Fiberglass widely used. As a new chemical materials, as compared with metal, Fiberglass with a high temperature, corrosion resistance, high strength, light weight, low moisture absorption, extend a small, electric insulation and high price range of features, energy saving effect is good, with a very a strong alternative, and the periodicity is not obvious. As the aforementioned various properties, glass fiber is widely used in various areas of the national economy, outstanding performance in: the construction sector, transportation, consumer products, electronic communications, oil and gas pipelines, aerospace aviation and wind fields. Fiberglass has a strong anti-cyclical. Although the Fiberglass industry has fluctuated, but as a new chemical materials, its anti-cyclical is much higher than other industries. China has become the world's major powers, while glass fiber, glass fiber gradually into the world power. Since the mid-20th century, 90 years, China'sFiberglass  industry has entered a rapid growth stage, 2007 the world's total annual production capacity of 40% in 2012 will exceed 60%. China Fiberglass Industry stagnant water are stronger China become the world's Fiberglass Fiberglass giant new market oligopoly. The world's Fiberglass industry has long been an oligopoly pattern; In recent years, as China's fiberglass industry's meteoric rise, China's three major Fiberglass giant is not only monopolized the domestic market and also the international glass market, the new oligarchs. The context of financial crisis, there is still growth in Fiberglass industry. The cyclical nature of fiberglass industry are far weaker than in traditional industries; glass of exports will not be significantly affected; oil pipelines and fan blades would not be a big decline in demand.

A, FRP has the following characteristics. (1) the relative density of light-weight high-strength between 1.5 to 2.0, only the carbon steel 1 / 4 to 1 / 5, but the tensile strength is close, even more than carbon steel, while the specific strength compared with high-alloy steel . Therefore, in aviation, rocket, spacecraft, high-pressure vessel and the need to reduce the weight of the products of other applications, all with outstanding results. Some epoxy FRP tensile, bending and compression strength can reach more than 400Mpa. Part of the material density, strength and specific strength in Table 1-1. (2) good corrosion resistance is a good corrosion-resistant FRP materials, air, water, and in general the concentration of acid, alkali, salt, and a variety of oils and solvents have a better resistance to diseases. Has been applied to all aspects of chemical corrosion, is being replaced by carbon steel, stainless steel, wood, non-ferrous metals. (3) good or excellent electrical properties of insulating materials used to make insulation. Still well under the protection of high-frequency dielectric properties. Microwave transmitted through sexual well and has been widely used in radar antenna cover. (4) The thermal properties of good thermal conductivity of FRP is low, at room temperature for 1.25 ~ 1.67kJ / (m · h · K), only the metal 1 / 100 ~ 1 / 1000, is an excellent insulation material. In the transient ultra-high temperature case, is ideal for thermal protection and anti-ablative materials to protect spacecraft at 2000 ℃ high-speed airflow over to withstand erosion. (5) can be designed to good ① as needed the flexibility to design a variety of structured products to meet the application requirements, you can make the product a very good overall. ② full selection of materials to meet product performance, such as: you can design a corrosion-resistant, and resistant to transient high temperature, the product of a direction of a special high-strength, dielectric and good, and so on. (6) process of fine ① according to the product shape, technical requirements, uses and the flexibility to select the number of molding process. ② process is simple, can be a shape, highlight the economic effects, especially for complex shape, a small number of easily forming the product, but also highlight the superiority of its technology. 2, can not ask a FRP to meet all the requirements, FRP is not a panacea, FRP also has the following shortcomings. (1) the low elastic modulus elastic modulus ratio of FRP timber twice as large, but lower than steel (E = 2.1 × 106) of small 10-fold, and therefore less rigid product structure are frequently and easily deformed. Can be made of shell structures, sandwich structure, but also through high-modulus fibers or do to strengthen tendons and other forms to cover. (2) Long-term temperature FRP can not be generally poor long-term use at high temperatures, common polyester FRP strength at 50 ℃ for more than a significant decline, it is generally at 100 ℃ for the following use; general-purpose epoxy FRP at 60 ℃ or above, the intensity obviously decline. But you can choose high-temperature resin, and make long-term working temperature 200 ~ 300 ℃ is possible. (3) The aging phenomenon of aging is plastic, a common defect, FRP is no exception, in the ultraviolet light, wind rain and snow yarn, chemical medium, under mechanical stress, etc. may easily lead to performance degradation. (4) interlaminar shear strength of low-level shear strength is borne by resin, so very low. Selection process through the use of coupling agents and other methods to increase the cohesive force between layers, most notably in the product design, try to avoid the shear layer. 3, FRP What are the methods of production? A: Basically, two broad categories, namely wet and dry-contact pressure forming. According to process characteristics, such as points, there are hand lay-up molding, lamination molding, RTM method, squeeze Rafah, compression molding, winding and so on. Hand lay-up also includes hand lay-up method, bag pressure method, injection method, the wet paste method and non-low-pressure mold hand lay-up method. Currently the world's most widely used methods are the following four types of molding. ① hand lay-up method: The main use of state are Norway, Japan, Britain, Denmark. ② injection method: The main use of state from Sweden, the United States and Norway. ③ molded law: mainly in Germany and other countries. ④ FTM France: The main use of state are European and American countries and Japan. China has more than 90% of the FRP products are hand lay-up method of production, and other molding method, winding method, laminating method, etc. (see chapter XI). Japan's hand lay-up method still accounts for 50%. From the world point of view, a considerable percentage of hand lay-up method still shows that it still has vitality. Hand lay-up method is characterized by wet resin molding, simple equipment, cost less, one can paste more than 10m overall product. The disadvantage is that the low level of mechanization, the production cycle is long, inconsistent quality. In recent years, China has introduced from abroad squeeze pulling, spraying, winding and other process equipment, with the FRP industrial development, new process methods will continue to appear.

2. To further expand the field of fiberglass met applications to address the application needs of the continually expanding. As a material offiberglass met  industry, how to better play to its own characteristics, and continuously expanding applications is a permanent topic, one of the key techniques to solve the fiberglass met and has been to enhance the coupling matrix is obtained the best combined results. In recent years, the international community more active areas of application development are the following: (1) reinforced thermoplastics. Almost all glass companies Qing Li meet this demand. ① chopped fibers: in the traditional injection extrusion FRTP products, with regard to enhance the production of fiberglass met objects of different short-cut specialty products, and constantly introduce new series of high performance, such as the OC's Micromax and Performax; JM Company Thermoflow and starstranLCF. at the same time actively developing for LFT dedicated fiberglass met products, such as JM's StarRovTMLFTplus; PPG's tufrov and other products. ② Continuous fibers: GMT component products are also in the promotion of. In order to further improve the performance FRTP products, fiberglass met, and engineering plastics businesses also active cooperation and development of continuous fiber reinforced thermoplastic matrix. Pre-mixed, pre-stain product development, including the mix of fiberglass met and plastic yarn, such as St. Brother Ban's twintex and JM's Comfil-G and CombiTex products. Used to enhance high-performance plastics (such as PPS, PEEK, etc.) pre-stain fiberglass met yarn, unidirectional tape, fabric stain pre-formed sheet material, suitable for suppression of higher performance FRTP products, has started large-scale production, expanding the composite materials in aviation and other high-tech fields. In short, through the cooperative development of upstream and downstream, FRTP product last five years, doubled. (2) fiberglass met knitted fabric. In order to meet the wind power blades, ships and sports equipment such as fiberglass met composite materials, the enhanced effect of the rapid development of fiberglass met knitted fabric, fiberglass metyarn in the fabric lining was straight (without analysis) state, and has more directivity (including uniaxial, biaxial and multi-axial fabric). To promote the development of knitted textile-based DR's development, such as PPG's INNOFIBer ○ R series of fiberglass met yarn. Some large enterprises dedicated specially developed high-quality fiberglass met yarn, such as the OC's Windstrand. Almost all the major glass companies are an extension of the production fiberglass met stitched fabric, of which the largest Ahlstrom Corporation. SGTF specially developed Maxflow, Tackified more suitable molding process such as product, while others stitch the fabric of professional fiberglass met processing, is also undergoing rapid expansion, such as Germany's SAERTEX Company. Needles, machine, three-dimensional woven substrate also enhanced the rapid development, especially in an empty Core enhanced substrate more popular. (3) fiberglass composite fabric. To meet the RTM and vacuum casting such as fiberglass met reinforced the development of closed-casting, fiberglass met composite fabric is also relatively rapid development, which includes different forms of fiberglass met composite to enhance the substrate, for example, SGTF's Multifilo, Multimat, un Juan complex, MulTiloop, MuLTixiAlS such as continuous strand mats, chopped strand mat, roving, a square cloth of different forms of composite fabric; OC's flowtex and flowro so. To give full play to enhance the composite material in the substrate best results, as well as in fiberglass met reinforced composite substrate surface and the fiber and foam SMIC, for example, the Multicore so SGTF. The composition of a bonded fabric (M), with lines and fiberglass met yarn, polyester sewing knot (S), acupuncture in three ways. (4) for construction products. Fiberglass met products companies in the construction sector in efforts to satisfy the demand for fiberglass met products. These products around the building energy-saving and security, should give full play to fiberglass met, high strength, non-burning, good weather resistance characteristics of the original products based on the development of new products. The more prominent are the following three aspects: ① shade fabric. In the original screens, mesh fabric, based on the newly developed adhesive fiberglass mesh, so that mesh mesh and organization more diverse, better adapted to a variety of curtain fabrics such as shade requirements. According to reports, shade fabric can save air conditioning energy consumption 30%, the United States, Hexcel Corporation, Japan's Nitto spinning, You Qika and other companies have developed a glass awning fabric products. Hexcel company has Screen Series; Nittobo's Verrescreen series gray light transmission rate of 67% ~ 93.6%, and shutter sun shading coefficient of between 0.29 ~ 0.49. ② gypsum corrosion surface material. Wallcloth in thin felt and decorative materials, based on the plaque along with the expansion of gypsum application, OC, JM, and Nittobo has developed a non-combustible gypsum board and glass fiber cloth affixed Mianbao felt instead of paper decorating material. Nittobo the development of such a fiberglass met cloth can also be additional features: Negative Ions function, antifouling deodorization function (light catalyst). ③ fire, lighting, drop cloths. In the silica fiberglass met cloth, PTFE-coated architectural membrane material based on the production, many companies have further developed the fire, lighting, drop cloths, for example, extruded insulation SGTF there TECO fabrics series, fireproof, industrial furnace curtain textiles. You Qika companies are also fighting the Japanese cloth, flammable apron and retaining sleeve products; Nittobo company's newly developed fiberglass met lighting drop cloths - Lightshade products, light transmission rate of between 41.9% ~ 61.4% is more applicable to complex shape of the roof and the side of varnish surface. (5) The heat-resistant fiberglass met products. Because of the heat-resistant glass fiber than most good, in many areas could on behalf of asbestos, in addition to the above-mentioned construction, civilian fire products, the large numbers used in the high-temperature industrial areas, including high-temperature furnace insulation, sealing , high temperature gas, liquid filtration, purification; welding protection; high-temperature equipment, pipe protection; heat-resistant conveyor belt and so on. In recent years heat-resistant fiberglass met products in a better development trend, and many a professional factory engaged in heat-resistant products are to develop. Textile industry in the last two exhibition Yicheng active state of affairs, such as Germany's KLEVERS, HKO, ASGLAWO, EUROCARBON Corporation, the United States, Newtex company, Belarus PoloTSK, the Netherlands Hiltex so. Direction of development of heat-resistant products: ① According to the different requirements of the use of heat-resistant fiberglass met selected varieties, selected from 300 ℃ one level of alkali, alkali, basalt, silica and quartzfiberglass met . Many companies produce both heat-resistant synthetic fiber products and ceramic fiber products to meet a larger range of heat-resistant and occasions, and sometimes also the use of different hybrid fibers. ② product variety is also bit applications on the market, yarn (including textured), rope, belt, sleeve, cloth, carpets, and blankets variety, of course, a variety of products, there should be many options specifications. ③ In order to better play to the heat-resistant glass and have a certain degree of processing and use of performance, would like to fiberglass met and fabric processing. The enterprises attach great importance to the development of this area to deal with but also the use according to temperature requirements, select the temperature polymer latex, silicone, and PTFE and so on, more in the development of high temperature inorganic suspensions, such as the graphite, vermiculite and ceramic oxides. ④ In order to further satisfy the use, care should be made into composite products, such as felt cloth composite, and aluminum foil compound, thereby directly causing a variety of fire blankets, and be insulated body to adapt to a complete set of shell, and so on. (6) electrical insulation products. Such as electronics, electrical appliances, electrical products, and a small increase in the trend toward fiberglass met material power must average annual growth rate of about 15% in recent years, and because of the rapid increment of China across the Taiwan Strait in the world, occupy more than half of market share. fiberglass metinsulation product development direction is: ① to meet the product thin, uniform, stable, fine. At present, production out of 0.015m / m thin cloth. As required per unit mass deviation <± 6%, so there is a low-Tex volatility, low air bubbles or flat glass, and fiber and fabric such as opening of new technologies. ② In order to meet the high frequency of electronic signals transmitted to require fiberglass met lower dielectric constant (ε <4.5). ③ In order to meet higher insulation levels, to better address high-insulation, heat-resistant plastic, a good composite, such as organic silicon, poly-4 ethylene oxide (PTFT), polyimide (PI) and so on. With the fiberglass met electrical insulation material production and the increasing specialization of the glass products have become increasingly demanding. (7) reinforced rubber cord. In recent years, this product is also the development of Japan's increasing NGF varieties and production capacity, has built four factories, Asahi (OC), the central and AGY, Miller companies, these companies are actively carried out technical development. There are two main research directions: first, to the glass fiber cord in the expansion of their own selection of component patterns. Components are not restricted to the traditional E fiberglass met still use high-strength glass fiber, basalt fiber, fiberglass met and other fibers as well as a mixed yarn. Patterns, not only the traditional continuous fiber, has also developed a short-cut fiberglass metcord, as fiber thickness and the cord structure, there are more series to meet different performance requirements. Secondly, the cord tire cord yarn, impregnated with the infiltration of agents and materials to enhance the continuous improvement in order to achieve a better rubber matrix enhancement, and can adapt to neoprene, nitrile, polyurethane rubber such as various enhancements. Also used to enhance the friction material, such as the production safety brake parts chopped glass fiber, the market demand is also expanding, optimistic about the base with phenolic resin has good compatibility and have sufficient heat resistance.

 

Thus, fiberglass met products in many areas, the successful application development, summed up the experience a few basic points: ① full attention to fiberglass met properties, the maximum avoid weaknesses. ② occupy a larger market share in the enterprise, has its own innovative features, independent brands and open up the field. ③ only benefit large-scale applications, new technology, strict management, quality is often accompanied by the scale for us. Third, drawing on the experience of a successful enterprise. The country's three fiberglass met giants, seize the opportunities, integration of resources, rapid expansion of scale, improve the technical level. Their main characteristics are: (1) Zhejiang rock: the largest, highest level, the world's largest 10 tons / output furnaces are being identified, 12 tons / output furnaces have also ignition, 14 tons / annual pool Kiln project has been started, a comprehensive integrated innovation embodied in the high level of large direct-melt production line. (2) Chongqing International: pay close attention to the core competitiveness of its alkali-free boron fiber production and the infiltration of agents ECR development leading position. (3) Shandong Taishan: the establishment of a national business development centers, to improve the technology development system and improve the technological innovation capability, equipment localization rate high emphasis on product development, chopped strand mats, thin felt the largest output. 2. fiberglass met products deep processing base - Jiangsu Jiuding Group, is the industry leader in the development of deep processing of products, in the absence of large foreign investment conditions, the solid development, fiberglass met and related products revenue nearly 5 billion yuan, 80% of export products. The main product in the alkali industry, fabrics, mesh products accounted for 40%, from yarn to fabric to deal with, ring ring constantly seeking improvement, the best quality grinding wheel mesh, the output of domestic top spot, ranked second internationally, are gradually moving toward the first 1. FRP hand lay-up started continuous refinement, adapt to the market, now has reached 130 million yuan output value, self-developed centrifugal FRP rod, car parts and wind turbine cover, but also to achieve international recognition, is trying to speed up the expansion. Many technology companies originated in the CSG hospital, but all further development. The enterprise innovation environment, the mechanism is good, has 16 patents. The market to adapt quickly, the size of the new product cycle is short. To sum up the experience of success can be seen that most of these enterprises according to their own actual conditions to determine the innovation and focus, take a rounded form features, such as OC company had homes textiles, homes S, ECR, efforts to develop new fiberglass met reinforced substrates ; St Scotia intended to enhance the Yang Ban Brother Building Materials; Jiuding Group also rounded off duct products. In the innovation process must pay attention to learning to expand their new knowledge. Can be said that there is no new knowledge, there is no innovation. At the same time we should pay attention to market research to predict market, improve market responsiveness. Advanced goals set high standards, there must be the first and the high market share in order to desire, but also practical to conduct detailed technical accumulation of work. To improve the level of equipment as soon as possible to solve large-scale production, but also the necessary logistic problems to solve. Fourth, take practical measures to promote scientific and technological innovation 1. According to corporate practice, developing innovative programs to enterprise development, industry-leading, market competition, high level as a starting point, and actively serve the business development strategy. According to the actual forming characteristics to determine the direction, focus and steps. Focus on innovation and mechanism construction, focusing on incentives (conditions, incentives) and accountability (performance appraisal). 2. In order to "project" as the clue, to promote innovation and the implementation of production plans on an annual basis to develop innovative plans, discharge sizes and different types of innovative projects, plans to launch the process of determining which is the process. Projects according to business needs, reflect the business advantages, should not have things set up for people, and follow the trend of operations. Note that the accumulation of project identification, feasibility, should not have lost a row of one, did not blindly seek perfection big. The continuous improvement of technology and equipment, and get the best production results. 3. To business development centers as a link, the formation of large-scale corporate innovation networks of enterprises setting up business development center (specifically responsible for small businesses) is an important measure for promoting innovation. Development Center to build an enterprise information platform, pay attention to gathering and business development related to professional sources of information and accumulation. To develop the center as a link, the coordination of innovation and the relations of production constitutes a reasonable knowledge, talent echelon form the Innovation Network. Business development centers should play forward, driving and coordinating role 4. Handle the relationship between absorption and innovation, and continuously improve innovative capability from the technical characteristics of fiberglass met and fiberglass met in China the status quo, recognizing innovative ways. Note that fiberglass met edge disciplines, involves many links and long features. Active outside the Association, to strengthen technical and product extension of the cooperation of units of a good grasp of integrated innovation. Learn from foreign advanced technology actively and effectively do a good job digestion and absorption re-innovation. Always pay attention to improve their ability to innovate, to take the patent strategy, to independent innovation.

Scientific and technological innovation is a subject of great concern to the industry, a hot topic. Today, economic globalization, China's economic After several years of rapid development, are proposed to create innovative social situation calls for. Glass industry in 60 years of development history, has been exploring the development of the situation to adapt to the innovation. Although Fiberglass met production in China has leapt to the world, but only the constant in-depth technical innovation, in order to achieve the Fiberglass met industry from a big strong. First, emphasis on technology, industry, a total of total of each industry has its own technology, it decided that from a technical level, the industry division, the common sense is the industry's laws, but also can be said is the industry's core technology, its development decisions the industry level. A total of advances in technology, in particular, need a leader in the industry under the leadership of painstaking accumulation, to work together to achieve. Summarized the experience at home and abroad, a total of fiberglass industry largely concentrated in the following four technology levels: fiber glass composition, decided the nature of performance; Fiberglass met melting system, decided to stability and performance; glass fiber forming, decided to fiber performance; Fiberglass met sizing, and products including treatment, decided to apply the effect. National scientific and technological development program attaches great importance to tackling common technology, because there were technology to improve the industrial level plays a vital role. China's Fiberglass met industry direct-melt technology, industrialization and development to date, there were technical enough to explain important. Industry-recognized OC company's core competitive in recent years have launched their advantex, windstrand yarn, and the new low-bubble Fiberglass met direct rovings and other new technologies, shows his deep grounding in technology accumulation. Let us look at a rough OC innovation company's three platforms: 1. For the environment protection and energy, 1997 OC introduced advantex yarn, the composition of fluoride, boron, while taking Oxy-Fuel and electric flux and dust emissions reduced nearly 85% of the total energy in production efficiency is improved by more than 20%, 6 million ton / year of Fiberglass met melting furnace the amount of heat per kilogram of only 1320 kcal. In its factory in Belgium Battice, also achieved the technological upgrading of wastewater treatment, water consumption reduced by 50%, wastewater pollution levels reduced by about 80%, by the European industry generally praised. OC is also actively developing advantex applications, the company is currently adcantex Fiberglass met production accounts for 70% of the total. 2. Advantex fibers in the development of the basis, OC is made to actively improve the melt technologies, introduced a new type of low-bubble Fiberglass met directly Twist Roving - SE8400LS, to ensure that air bubbles were much lower than 0.5 / g. This roving has a particularly good resistance properties, mechanical strength, compared with E Fiberglass met has better corrosion resistance and heat resistance, thereby reduction of brittle fracture, for the manufacture of high-voltage insulator, can greatly improve the safety of insulators. OC Norway Birke Juan land plant known to achieve bubble-free production. 3. To meet the wind power blades of glass fiber strength, elastic modulus and strain fatigue properties of higher demands, OC recently launched Windstrand direct roving. Tensile strength than E Fiberglass met increased by 35%, rigidity 17% increase compared with advantex fiber tensile strength increases by 33%, the tensile modulus increased by 19%, fatigue performance enhancement of 25% to 50%, which is a kind of alkaline-earth aluminum silicate Fiberglass met. The new melting and molding technology enables some performance more excellent alkali-free borosilicate Fiberglass met to achieve the large-scale production. OC's success is that they attach great importance to innovation of the "platform" concept, that is, a total of Technology - common law - the core technology - the core competitiveness, better to "innovation" push from a big strong. Second, the current focus on technological innovation fiberFiberglass metoverview of the development trend of international and domestic glass, the author believes that the current focus of China's Fiberglass met technological innovation has the following two aspects: 1. Further improve the Fiberglass met production technology to solve its own technical bottlenecks, has a price advantage to provide high-quality products to energy-saving emission reduction, quality optimization, species diversity in three directions for sustainable development. From the effort to narrow the gap with the advanced start, from the initial digestion and absorption re-innovation, the transition to integrated innovation, and thus independent innovation. The whole industry on the one hand to promote advanced furnace technology, the other hand, should strive to catch up with international advanced furnace technology. Here are some representatives of foreign advanced level of information for reference: ① energy-saving aspects: the United States a company a 60000 / year of E-Fiberglass met melting furnace, using pure oxygen combustion and electric kiln top flux, the amount of heat per kilogram of Fiberglass met only 1320 calories, the company's non-alkali Fiberglass met melting furnace has reached the highest melting rate 2.7t/m2 · day. Abroad in support of the Government is also actively developing new melting technologies, including promotion, improving access pure oxygen combustion technology, the development potential at the end of the intermediate combustion melting furnace tests and fire away from the melting of plasma technology development research. ② Quality Optimization: the foreign company's drawing an alkali-free direct-melt yields up to 96%, the company's new low-bubble Fiberglass met direct rovings, its bubble content can guarantee less than 0.5 / g, with considerable good resistance properties, mechanical strength was also high. The highest level of quality raw silk Tex fluctuations of up to 1% ~ 1.5%. There are high quality Fiberglass met fluid as a guarantee, to the continuous improvement of molding technology, direct-melt has achieved the 6000 leak hole plate production and six sub-pulled drawing operations . Production of the United States a crucible of electronic glass products, the company produced four points with 800-hole pull-E225 yarn per hour output was 10 kg ~ 12 kg. This is our crucible method for manufacturing enterprises learn from. ③ varieties aspects: In order to meet the functional requirements of a higher glass for more recent years, distinct from the traditional E Fiberglass met varieties of the rapid increment. First, to improve the corrosion resistance of glass fiber, especially in acid resistance, OC's advantex Fiberglass met aggregate has more than E Fiberglass met. Canada and China's rapid increment of ECR glass fiber, St Costa Rica classes ARcotex also incremental. In addition, there are high-strength, heat resistance, low dielectric properties of high strength, high silica, basalt, low dielectric with special features such as glass fiber, but also are constantly improving production technology, expanding production. It is obvious that the key to improve the production technology is still Fiberglass met Fiberglass met melting technology and molding technology. Melting furnace technologies, including combustion technology and design, molding technology is the key to drain board design, materials and processing. These will have to take the initiative by the Fiberglass met manufacturers to continuously explore the development. Experience has shown that, in the refractory, drain board material and processing the active cooperation of the professional manufacturers to continuously improve and enhance the also very important.

1, FRP mold making one, the main module production: production of the main mold material there are many general requirements of material easy to make decisions mold forming, easy to break, and there is good stability, and so on. Such as wood, plaster, wax and so on. We usually use are wood. Drawings or die based on product drawings, made from wood wooden master model. 2, the main mode repair: the main module must be repaired and can only turn the system of production modules. Dressing, including play putty, plastic, size, the more positive reinforcement. This process mainly for wood mold surface and the whole to do the basic treatment, to ensure that wood mold in the size and form is consistent with the drawings. 3, the main mold surface treatment: This process has glue, clothing, rubber clothing curing, grinding, polishing, playing stripping wax. In front of a good process to deal with the main mode on the sprayed gel coat, and then gel coat such as curing, after curing gel coat polish gel coat surface with sandpaper. From the dozens of numbers in general have been hit rough sandpaper No. 1000 of around fine sandpaper. Once on shore, sand paper and begins to mold polishing the final product marked with mold release. Until this point, the main mode of production to an end. Take over the master mold can be used to create the production mold. This process, the use of many materials and industrial equipment. Carpentry of wood and the corresponding apparatus is necessary. There are also: putty (also known as Putty), sandpaper, coarse sandpaper from the dozens of numbers to more than 1000 numbers of fine sandpaper, plastic clothing (general use of the product can be gel coat), mold cleaning agents, sealing agents, polishing paste, mold release wax. In addition, the workers also use some small appliances, such as sanders, polishing wheel, gel coat spray gun, air pump (or other gas source). 4, the production mode of reproduction: the main module to lay stripping wax, you can turn the system of production mold, they are producing mold reproduction processes are as follows: ⑴ spray mold gel coat: Due to start production of the production mold, so you must use better performance mold plastic clothing, to ensure that the ultimate effect of the mold. And requested the jet reached a certain thickness. ⑵ mold shop floor: the initial solidification mold gel coat, you can start a shop floor. Shop floor processes can not be too fast, usually 2-3 a day shop-layer glass cloth or glass fiber mat. Shop floor to use a certain amount of mold resin. The performance of this resin is better than ordinary resins. Shop floor workers in the process should be equipped with rubber, or resin to be increased for promoting agent and curing agent and then use the glue tool to glue and spread a layer of fiberglass fabric coated layer of glue, and use the flat iron rollers driven fabrics, Pai go bubbles, so that glue evenly. After the designated thickness, layer an end. Under normal circumstances the thickness of the mold to achieve the product 3-5 times the thickness. Therefore, the time ply generally longer, 6-7 days for sustainable bar. ⑶ mold curing reinforcement: Mold can be a natural cure, but also heat-curing, it is generally desirable to have a natural cure period. Natural cure period, to give mold reinforcement, so that mold damage in the production process Buzhi Yu. ⑷ production of Die Surface Treatment: production mold cured to the required time, you can play down from the main mold, mold ways from the workers by hand from mold, can also be used to effect high-pressure gas model. After modeling, the production model from the same need to do surface treatment, including the fight sandpaper, polishing, draw processing line, playing stripping products. After playing stripping products can be used to produce product. The materials used in this phase are: mold gel coat, mold resin, ordinary resin; curing agent, accelerator; glass fiber surface mat, fiberglass mat, fiberglass cloth; fine sandpaper, mold cleaning agents, sealing agent, polish paste, mold release products (mold release wax, semi-permanent release agent and so lines). In addition to the instruments used in mold processing tools, plus upper berth layer tools: such as rubber rollers, plastic brushes, rollers and so on. Mold making is an elaborate and lengthy process, generally a mold production cycle before and after close to a month's time.
