frp water tank

FRP fundamental components are resin and glass fiber (including woven, mat and so on),it is a composite material that it takes fiber (including glass fiber, carbon fiber, organic fiber and other metals, nonmetallic fiber) as reinforced material and resin (the main are epoxy resin, polyester resin, phenolic resin) as adhesive and other accessory material (the main accessory material are release agent, firming agent, catalyst, sealant, UV light stabilizer, gel coat and so on).

Glass fiber is a new function material and structural material in the inorganic nonmetallic material. It has a series of outstanding characteristics such as thermostable, corrosion resistance, high intensity , small specific gravity, low moisture absorption, small prolongation and good insulationand so on .

Since it has been more than forty years in China it impels technology transformations in traditional industry, agriculture and architecture industry and products renewal, at present it has been used in electron, communication, nuclear power, aviation, astronautics, weapon, naval vessel and ocean exploitation, genetic engineering, it is a indispensable continous development high-new technology material in 21st century in China.

Resin is a basic material, it may choose the different resin according to special requirement of different products.

The unsaturated polyester resin, epoxy resin and ethylene ester resin are used usually.Unsaturated polyester resin viscosity is small, the infiltration performance is good, the air bubble is easy to eliminate, the gelatin time may regulating control according to the requirement, the craft performance is the best, the comparative price is also low, therefore the rigidity is lower compared to epoxy resin, the solidification shrinkage rate is also big, but it still applied widely.Epoxy resin bond stress is better, it is used in high strength frp products.

But the viscosity is high, the technology performance isn't good, the price is also expensive. The vinyl resin is applied widely because of its superior anti-corrosive and heat resistance in the anticorrosion domain. Others includes phenolic resin, furan resin and some high performance resin.

The phenolic resin is regarded because of its superior flame-resistant.FRP is a character bonding product of glass fiber and organic resin.

Therefore the frp products have outstanding characters such as high intensity,light weight,corrosion resistance and good insulation which the glass fiber has, the performance is good as well as metal fiberglass is cemented in organic resin, it could not friction directly and also not flexing, so it avoids the big brittleness, not wear-resisting, not folding endurance.
