Resin manhole covers are widely used in urban roads, communications, power supply, drainage, chemical, sewage, gas and other industries, but do you really understand resin manhole covers? One of the biggest features of resin manhole covers is that it has no recovery value at all, completely solves the problem of anti-theft, and effectively reduces the phenomenon of theft of manhole covers. Let us look at the specific advantages of resin manhole covers together.
1. High strength: high-molecular-weight composite plastic composite materials have high compressive, bending, and impact strength and toughness. After being used for a long time, the product will not be crushed and damaged, which can completely prevent the "urban black hole" accident.
2. Beautiful appearance: Exquisite designs on the surface of the inspection cover are designed to beautify the urban environment.
3. Easy to use and light weight: The product weighs only about one-third of cast iron, which is easy to transport, install and repair, which greatly reduces labor intensity.
4. Anti-theft: The composite plastic synthetic material has no recycling value and is natural anti-theft; according to customer needs, a lock structure is provided to prevent theft of property in the well.
5. Strong weather resistance: This product uses high molecular weight materials with large molecular weight and strong chemical stability as raw materials for manhole covers. Through scientific formula, advanced technology and perfect technical equipment, the product can be used normally at -50 ° C to 150 ° C.
6, low noise: the application of synthetic materials, special lock structure design, completely solved the noise caused by inspection manhole cover to the city.
Resin manhole covers are made of unsaturated resin as the base material and continuous glass fiber is used as the reinforcing material for the composite material manhole cover. Because the bottom structure is used in the structure, the material is uniformly stressed, and continuous fiber is used for reinforcement. The bearing capacity and later bearing capacity of the manhole cover are guaranteed. From the perspective of bearing capacity, the service life is longer; the manhole cover is layered and compounded, and the open-air part is made of wear-resistant and aging-resistant materials. From the standpoint of rolling resistance and aging resistance of vehicles , The service life is relatively long.
The appearance of resin manhole covers has brought great changes and impacts to urban life. It not only has the basic functions of other manhole covers, but also has many new practical new functions. The resin manhole covers can hold a foothold in today's society. It shows that it is currently recognized by the public, because it is recognized, it is likely to have greater surprises and performance.
