　　復(fù)合井蓋為您提供 復(fù)合井蓋鑄鐵井蓋水泥井蓋--玻璃鋼井蓋的承載力

　　玻璃鋼井蓋用不飽和樹(shù)脂作基體材料，用連續(xù)玻璃纖維作增強(qiáng)材料的玻璃鋼井蓋，因結(jié)構(gòu)上采用鍋底結(jié)構(gòu)，材料受力均勻，并使用連續(xù)纖維增強(qiáng)，不用鋼筋增強(qiáng)，材質(zhì)均為復(fù)合材料，井蓋的承載能力及后期承載能力有保障，從承載能力角度看，使用壽命較長(zhǎng);井蓋采取分層復(fù)合，露天部分采用耐磨、耐老化材料制作，從耐車(chē)輛碾壓和耐老化角度看，使用壽命相對(duì)較長(zhǎng)。

　　這種玻璃鋼井蓋是用不飽和聚酯樹(shù)脂作基體材料，用玻璃纖維作增強(qiáng)材料，輔以一定剛性材料。結(jié)構(gòu)上采用鍋底結(jié)構(gòu)，底部抗拉材料受力均勻;材質(zhì)上分上下兩層，上部采用耐磨、耐老化材料，產(chǎn)品的使用壽命長(zhǎng)。下部采用連續(xù)玻璃纖維增強(qiáng)，可以使井蓋具有足夠的承載能力，而不需任何鋼筋增強(qiáng)，是幾種井蓋中綜合性能較好的一種材料井蓋。

　　Composite covers provide you with cast iron manhole covers cement composite covers - bearing capacity of FRP covers

　　FRP covers unsaturated resin as matrix material , with continuous glass fiber FRP covers reinforcements , because the structure using pot structure, material force uniform , and the use of continuous fiber reinforced , not steel reinforced, are made of composite materials, carrying capacity and carrying capacity of the latter covers the protection, from the perspective of carrying capacity and longer service life ; covers stratified complex , open-air part of the wear-resistant , anti-aging materials, from the vehicle rolling resistance and anti-aging perspective, relatively long life .
