复合井盖为您提供 复合井盖 铸铁井盖 水泥井盖--玻璃钢井盖的承载力

玻璃钢井盖用不饱和树脂作基体材料，用连续玻璃纤维作增强材料的玻璃钢井盖，因结构上采用锅底结构，材料受力均匀，并使用连续纤维增强，不用钢筋增强，材质均为复合材料，井盖的承载能力及后期承载能力有保障，从承载能力角度看，使用寿命较长;井盖采取分层复合，露天部分采用耐磨、耐老化材料制作，从耐车辆碾压和耐老化角度看，使用寿命相对较长。

这种玻璃钢井盖是用不饱和聚酯树脂作基体材料，用玻璃纤维作增强材料，辅以一定刚性材料。结构上采用锅底结构，底部抗拉材料受力均匀;材质上分上下两层，上部采用耐磨、耐老化材料，产品的使用寿命长。下部采用连续玻璃纤维增强，可以使井盖具有足够的承载能力，而不需任何钢筋增强，是几种井盖中综合性能较好的一种材料井盖。

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 .
