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;井蓋采取分層復(fù)合,露天部分采用耐磨、耐老化材料制作,從耐車輛碾壓和耐老化角度看,使用壽命相對較長。


這種玻璃鋼井蓋是用不飽和聚酯樹脂作基體材料,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。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 .


This fiberglass covers are made with unsaturated polyester resin matrix material reinforced with glass fiber materials, supplemented by some rigid material . Structures using structural pot bottom material tensile force uniform ; divided into two layers on the material, the upper part of long life wear, anti-aging materials, products. The lower part of a continuous glass fiber reinforced, can make the covers with sufficient carrying capacity, without any steel reinforced, is one of several wells in a better overall performance material covers .
