FRP products
FRP products introduction:
Glass steel products refers to the resin and glass fiber as raw materials, finished products, glass steel products are mainly glass steel tank, mixing tank, glass steel cooling tower FRP FRP tank FRP chairs FRP pipe, glass steel trash. The scientific name of glass fiber reinforced plastics is glass fiber reinforced plastics. Is a new type of composite material developed in the early twentieth Century, which has many advantages, such as light weight, high strength, corrosion resistance, thermal insulation, insulation, sound insulation and so on. Because of the strength of the equivalent steel, and containing a glass component, also has the properties of glass color, shape, corrosion resistance, electrical insulation, insulation such as glass, as the history of the formation of popular name "glass steel".
Types of FRP products
[classification]
1, glass fiber reinforced plastic storage tank: hydrochloric acid storage tank, chemical storage tank, anti-corrosion tank, pressure tank, fermentation tank, food cans, transport tanks, mixing tanks, etc.;
2, glass fiber reinforced plastic pipe: glass fiber reinforced plastic sand pipe, glass fiber reinforced plastic pipe, glass fiber reinforced plastic pipe, cable protection tube, etc.;
3, glass fiber reinforced plastic water tank: magnetic square box, T box square box, universal square box, crossed square box, inspection box, etc.;
4, environmental protection chemical equipment: desulfurization tower, drying tower, washing tower, sewage treatment equipment, municipal water supply pipeline.
[function]
The glass steel products is a good corrosion-resistant materials, first with resin (phenolic, epoxy resin and polyester resin) make them coagulation as a whole, made of material, its tensile strength can be comparable with steel - so called glass steel. We see here should understand a little, because the hardness of the product is very high.
The tensile strength of FRP products is close to or even greater than that of carbon steel, while the specific strength can be compared with that of advanced alloy steel. As a result, it has excellent results in aviation, rockets, space vehicles, high pressure vessels and other applications that require a lighter weight. FRP is a good corrosion resistant material, it has good resistance to the atmosphere, water and the general concentration of acid, alkali, salt and a variety of oils and solvents. But it is also very obvious shortcomings, is his resistance to long time high temperature resistance is relatively poor, the general FRP can not be used long under high temperature, general polyester FRP at 50 DEG strength is decreased, generally used only at 100 DEG C, the common epoxy FRP at 60 DEG C, the strength decreased significantly.

[anti-corrosion Characteristics]
Glass fiber reinforced plastic products with its superior corrosion resistance has become a medium of transmission in many industries, but it is based on what is to achieve its unique characteristics. FRP structure inner lining layer, structure layer and the outer protective layer three part of filament winding. Among them, the resin content of the lining layer is high, generally more than 70%, and the resin content of the inner surface of the resin layer is as high as 95%. By using resin choice of lining, the glass steel products with different corrosion resistance in the transportation of liquid, so as to meet the different needs of the work; for anti-corrosion occasions, only external protective layer of resin was carefully chosen, it can achieve the purpose of using the different external coating.
Glass steel products according to the different corrosion environment, can choose different anti-corrosion resin, including: isophthalic unsaturated polyester resin, vinyl resin, bisphenol A resin, epoxy resin and furan resin, were selected according to the specific circumstances of the acidic environment, using double A phenol resin, furan resin and so on; alkaline the environment, vinyl resin, epoxy resin and furan resin; used environment of solvent, selection of furan resin; when acid, salt, solvent corrosion is not very serious, you can choose to use isophthalic resin cheaper. Through the selection of different resin in the lining layer, the glass fiber reinforced plastic products can be widely used in the working environment of acid, alkali, salt, solvent and so on.
Production process of FRP products
[curing process]
The curing of glass fiber reinforced plastics can increase the strength by more than 10%. Vacuum curing is one of the effective ways to improve the strength of FRP products. Products in the manufacturing process, there are still some residual solvents and other low molecular weight, can not be completely removed under atmospheric pressure.
Hinder the bonding of resin and glass fiber, thus affecting the strength of FRP products. The vacuum curing method can make the low molecular weight more volatile, and make the glass fiber reinforced plastic products more compact. Therefore, the strength of the container can be improved.
The curing agent in the binder should be less volatile under the condition of reducing pressure, otherwise it will lead to excessive loss of curing agent, curing the product is not complete, but reduce the intensity.
[process]
The inspection process is verified according to the production process, inspection process inspection system since the implementation of mutual inspection, products in every step of mixing the ingredients and lining, winding, trimming, demoulding, by the operator to implement self-test, and by the next step of the procedure for inspection, inspection is the main content of appearance, size, structure test fill in the product process and inspection records, a record of each product, product number and process inspection record number corresponding to each other.
[product acceptance]
The last procedure for product acceptance, should be the main test is whether the smooth surface of the glass steel products, no impurities, no fiber exposed, no visible visual crack, no scratches, white and layered; outer surface should be smooth, no fiber exposed, no air bubbles and serious uneven color.
