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. Glass fiber reinforced plastics is the scientific name of glass fiber reinforced plastics, commonly known as glass fiber reinforced plastics. Is a new type of composite material developed in early twentieth Century, it has many advantages, such as light weight, high strength, anti-corrosion, insulation, insulation, noise, 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".
Characteristics of glass fiber reinforced plastic products
[classification characteristics]
1, glass steel tank: hydrochloric acid tank, chemical tank, anti-corrosion tank, pressure tank, fermentation tank, food tank, transport tanks, mixing tanks, etc.;
2, glass steel pipe: glass steel sand pipe, glass steel pipe, glass steel duct, cable protection pipe etc.;
3, glass fiber reinforced plastic water tank: magnetic square box, T type slot square box, universal square box, square box, inspection square box, etc.;
4, environmental protection chemical equipment: desulfurization tower, drying tower, washing tower, sewage treatment equipment, municipal water supply pipeline, etc..
[feature]
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 product is very high hardness.
The tensile strength of FRP products are close to or even more than carbon steel, rather than the intensity can be compared with high alloy steel. Therefore, in the aviation, rocket, spacecraft, high pressure vessels and other products in need to reduce the weight of the application, have excellent results. FRP is a good corrosion resistant material, to the atmosphere, water and general concentration of acid, alkali, salt, and a variety of oils and solvents have better resistance. 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 strong anti-corrosion ability to become a transmission medium in many industries, but it is by virtue of what 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 inner liner layer resin content is high, generally above 70%, the inner surface of the resin layer resin content of up to 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. The glass fiber reinforced plastic products are widely used in the working environment of acid, alkali, salt, solvent and so on, which can be widely used in the work environment of acid, alkali, salt, solvent and so on.
Production process of glass fiber reinforced plastic products
[curing process]
Curing of glass fiber reinforced plastic can be increased by more than 10%, vacuum solidification is one of the effective ways to improve the strength of glass fiber reinforced plastic products. Products in the manufacturing process, there are still some residual solvents and other low molecular weight, can not be completely removed at atmospheric pressure.
To prevent the resin and the glass fiber firmly bond, thus affecting the strength of glass fiber reinforced plastic products. Vacuum solidification method can be used to make the low molecular volatile matter more completely, so that the glass fiber reinforced plastic products are more compact. So it can increase the strength of the container.
The curing agent in the binder should be less volatile in the reduced pressure, otherwise it will make the curing agent lose too much too much, so that the product can not be cured completely.
[process detection]
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.
[final 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.
Glass fiber reinforced plastic products
Glass fiber reinforced plastic products can be used widely.
