The international community often referred to as glass fiber reinforced plastic polyester-based plates, written in English FRP (Fiber Glass-Reinforced Plastics) glass plate refers to the unsaturated polyester resin impregnated glass fiber mat, glass fiber fabrics or chopped fibers, and condensate rubber curing and obtained the products, it has a light weight, high strength, impact performance, particularly those with a unique translucent nature of construction of building structures for lighting and lighting of greenhouse crops marked effect, as well as excellent corrosion resistance, resistance to atmospheric aging, simplify the design, installation, replace them simple and can choose the color.
A glass plate with the raw materials
A reinforcing material
FRP panels are usually reinforced material of choice for the glass cloth, untwisted glass rovings, chopped glass fiber mat.
Twist Glass Roving
Continuous FRP corrugated molding process of glass used in untwisted rovings should have a good cutting, decentralized nature, branch invasive, does not produce static electricity or less.
Short-cut glass fiber mat is usually used in the current domestic chopped glass fiber mat of the specifications, EMC300, EMC450, EMC600 three, with a density of uniform, soaked in good, clean, weather, light transmission and so on.
2 resin matrix
Continuous FRP corrugated sheet forming process the majority of selected unsaturated polyester resins (UP) resin, has high mechanical strength, good weatherability and impact resistance, but also has a lower shrinkage rate and the appropriate viscosity in order to impregnated glass fiber has a good nature of Pai Pao.
3 Films
FRP corrugated sheet forming a continuous film with the requirements, the surface smooth, without folds outside the most important thing is have a high tensile strength and a certain degree of heat resistance, to ensure that the process of forming corrugated film is not deformed, according to use of FRP corrugated film film and anti-aging process can be divided into two kinds of films.
a single fluoride films, anti-aging effects of atmospheric and light excellent, can be used for corrugated board up to 20 years.
b polyester film.
4 Other supporting material
FRP plates used in the resin formulations of the supporting materials, initiator, accelerator, pigment lakes, UV absorbers, and now the widespread use of methyl ethyl ketone peroxide, cobalt accelerator solution for different bitterness, so that corrugated pure color, in particular, is to make transparent board for more than 87% light transmission rate.
High-quality light board has the following features:

1, transmission - up to 85% light transmission for more than 90% of the sun blocking ultraviolet radiation.

Lighting panels in a greenhouse on the Application of

Transparent glass steel Greenhouse:
-------------------------------------------------- ------------------------------
      A transparent glass fiber reinforced plastic greenhouse in a transparent glass fiber reinforced plastic instead of glass, built a greenhouse. Practice has proved that in a transparent glass fiber reinforced plastic greenhouse cultivated plants and crops, can significantly improve the yield and quality to achieve results. For example, Wuhan University and Beijing Chinese holly leaf jointly built by the transparent glass fiber reinforced plastic greenhouse, using even the inter-frame structure, simple structure, easy construction and low cost. Greenhouse cucumber, tomato significantly increase production, the data show that glass fiber reinforced plastic greenhouse in winter cucumber yield under the same conditions than in glass fiber reinforced plastic greenhouse, high yield 55%, in the spring tomato yield 48%. In Europe, transparent glass fiber reinforced plastic greenhouse cultivation of vegetables and flowers than the annual output of greenhouse glass, steel 10% ~ 20%. Beijing FRP apple orchard louang nursery greenhouse was imported from America, and in nurturing seedlings, planting flowers, planting of rare trees and tropical plants has made great achievements.

Transparent glass fiber reinforced plastic greenhouse structure:
-------------------------------------------------- ------------------------------
Transparent glass and steel is light and the carrying capacity of multi-functional composite materials used to build greenhouses can simplify the design of building structures, save material, reduce costs and facilitate construction.

      Many forms of glass fiber reinforced plastic greenhouse, small greenhouse often used single-slope roof structure. The light side of this greenhouse is transparent glass fiber reinforced plastic plates, in order to reduce the support structure, the use of transparent glass, the strength of steel, light panels can be designed to build cross-section for waveform, curved, folded plate-shaped and trapezoidal and so on.

      Large glass-steel greenhouse can be used with cross-vaulted roof, or double-sloping roof, this greenhouse can be used load-bearing structure of aluminum, galvanized light steel and prestressed reinforced concrete structures. Greenhouse-span is generally 6 ~ 12m, can also be designed to be larger, such as Germany built for the 18m span steel glass greenhouse, sloping transparent glass roof is a two-wave cross-section three twisted steel arch plate, a transparent glass side walls folded steel plate, arch seat and columns of steel.

      In a greenhouse scale, done specifically statistics, greenhouse area to 300 ~ 400m2, 900 ~ 1000m2, and 1000 ~ 1500m2 up. Small area of greenhouse used for kinds of melon, nursery, 1000 m2 large area is mainly used for greenhouse cucumbers, tomatoes, eggplant and other vegetables growing. To save energy, farmers in northern China more than a single-slope greenhouse plus insulation cover.

A variety of sunlight on plant photosynthesis:
-------------------------------------------------- ----------------------------
In vegetables, flowers and crops, the growth process, the role of its light is only a part of the sun - visible light. Too much solar radiation the Earth's surface on the UV wavelength is 290 ~ 400um, visible light is 400 ~ 760um, infrared light and far-infrared light for more than 760um.

    ⑴ It is an invisible ultraviolet short-wave light, the wavelength range of 290 ~ 390um, on plant growth would not achieve a positive role, but the metabolism of plant growth, as well as changes in flower color is essential. Therefore, planting eggplant, cherry, flowers, greenhouse, hoping ultraviolet light through a little bit more. For the Department of root and leaf vegetables, flowers, remove the UV light contribute to the growth of plants. Impervious to UV light in the greenhouse cultivation of vegetables, Komatsu dish, round pepper, their photosynthesis faster than in the open air cultivation large and Sclerotinia sclerotiorum on cucumber, tomatoes inhibit the toxic diseases.

    ⑵ wavelength of visible light visible light range 400 ~ 760um, removing 500um below the wavelength, can improve the quality of tea. In a translucent membrane, under selective cultivation of soybeans, crude protein content increased; in the blue film under cultivation, increased water content; in pink under the crude fat content of films increased, while root systems are well developed. In the plant growth process, the visible light is very important, in which red-orange light on crops play a key role in photosynthesis, crops also depend on the formation of vegetative organs of blue, purple. Visible light transmittance and thus directly affect the production of vegetables and flowers, and quality.

    ⑶ infrared wavelength 760um or more infrared light alone, 760 ~ 800um wavelength of light is necessary for bud formation and flowering of light. 800um above the light is not absorbed by crops, only reflected or transmitted.

    In the radiant energy of sunlight, 740um or more near-infrared light accounted for 50% to 60%.

China Fiberglass: weak demand caused by rapid decline in profitability

by: jinjiudingfrp   Keywords: fiberglass, fabric

Lower than expected earnings in 2008: China Fiberglass, today announced the 2008 annual report. In 2007 the company achieved operating income of 4.008 billion yuan, up 25.23 percent; operating profit of 610 million yuan, down 13.35%; attributable net profit of 244 million of listed companies, down 18.87 percent, retrace eps0.57 yuan, lower than our expectations. Company's profit lower than expected fourth quarter is mainly due to the rapid decline in profitability and trading of financial assets losses.

Weak demand, a substantial decline in profitability in the fourth quarter: With the global macro-economic growth slows, demand for glass products, were greatly affected. 2008 sales of fiberglass fabric and related products 580,000 tons, lower than we expected about 15%. In November, the company conducted a major fiberglass fabric prices drop nearly 10% increase. Therefore, the four quarter alone, the company's consolidated gross profit margin slipped to 20.5%, while the three-quarter one-quarter of 35.43%. The full year gross margin of fiberglass fabrica , 32.58%, down 0.88 percentage points more than in the first half fell 2.69 percentage points.

The end of 2008, the company stock commodity 724 million yuan, rose by 7.6 times. 2008 rock group net profit of 667 million yuan, an increase of 11.32%.

Highlighting financial pressure, trading gains and losses drag on earnings of financial assets: Due to the continued expansion of production capacity, the financial cost pressures highlighted in 2008, the company's financial costs of 332 million, an increase of more than 100%. 2008 operating cash flow -4.57 billion, operating cash flow per share -1.07 yuan, down 175.59%.

2007 companies to invest in Tianwei change security transactions such as financial assets for the company contributed 68.08 million yuan of net profit, and since 2008 the stock market Shenfutiaozheng, trading financial assets, a loss of 38.12 million yuan upside down. Although the transfer of Building Material Investment Co., Ltd. company's stake in a return 19.29 million yuan, and the government subsidy year on year revenue increase of 46.15 million yuan, but the gains and losses on trading financial assets are still unable to compensate for the impact.

Industry lead outstanding waiting for the bottom of the pick-up: in 2008 the Group of new capacity is 380,000 tons rock end of the year's total capacity to crack the 90 million tons, as the world's largest fiberglass production company. Advantage of the company's economies of scale is very prominent, is the industry's lowest unit consumption products company. We believe that, although the degree of glass fiber industry, is currently in the bottom of the economy, but with the macro-economic recovery, demand for glass fiber will be gradually picked up at the bottom. 2009 fiberglass fabric in the field of wind power and the expressway will have a significant improvement in sales. We expect that this year sales of 750,000 tons fiberglass, consider the contribution of stock returns are expected this year's eps at 0.68 yuan, 2010 and 2011, without regard to security returns, expects eps were 0.91 yuan and 1.27 yuan. Taking into account the industry at the worst of times and asset injection expectations, we adjust the company's rating to "overweight-B", 6-month target price of 20 yuan, inventory digestion cause for concern.
