Development potential and advantages of composite manhole covers

Introduction to Chongqing Composite Well Cover Composite well cover is a new type of well cover with high efficiency, environmental protection and low cost, which is made of unsaturated polyester resin as the primary material and limited molding technology. The composite data well cover is formed by one-time restriction under high temperature and pressure, so it has high strength, high density, high tensile strength and outstanding impact. Together, the composite data well cover also has the advantages of wear resistance, corrosion resistance, environmental protection, no pollution and no need to protect. Composite well covers use mesh reinforcement to add internal strength. Chongqing composite well covers can quickly disperse the pressure generated by people and vehicles, ensuring people's own safety and industrial safety. Because the metal used in composite well cover does not exceed one tenth of its own weight, and the strength of composite well cover is extremely high, Chongqing composite well cover does not have much value for theft.

The fiber reinforced data of a composite well cover is characterized by small specific gravity, large specific strength and specific modulus. For example, according to the data of carbon fiber and epoxy resin composite, the specific strength and specific modulus of Chongqing composite well cover are much larger than those of steel and aluminum alloy. Chongqing composite well cover also has excellent chemical stability, friction reduction and wear resistance, self lubrication, heat resistance, fatigue resistance, creep resistance, noise elimination, electrical insulation and other functions. The composite of graphite fiber and resin can obtain the data that the expansion coefficient is almost equal to zero. Another feature of Chongqing composite manhole cover fiber reinforcement data is anisotropy, so fiber placement can be planned according to the strength requirements of different parts of the parts. The aluminum matrix composites reinforced with carbon fiber and silicon carbide fiber can still maintain sufficient strength and modulus at 500 ℃.

According to different parts of the composite well cover, different enhanced data are used. The surface layer of Chongqing composite well cover is filled with quartz sand particles, which has good wear resistance; With the addition of ultraviolet absorber, Chongqing composite well cover has improved the anti-aging effect of composite data well cover. The structural layer can give full play to the characteristics of continuous fibers. Chongqing composite well cover makes the composite well cover without any reinforcement, with higher bearing capacity, longer service life and more market competitiveness.
