Usually we see a variety of manhole covers on the road, and the role of each kind of manhole cover is different. In recent years, the utilization rate of composite well cover is higher and higher. The most prominent feature of the composite manhole cover is that the material itself has no secondary use value and has the function of natural anti-theft, which directly solves the big problem of manhole cover being stolen.
Advantages of composite manhole cover products:
1. Strong anti-theft performance: the resin composite manhole cover is made of unsaturated resin, glass fiber and other materials and reinforcement framework by special production process. After high temperature grinding and pressing, the material has no recycling value, and it is very difficult to take out the reinforcement (the cost of taking out the reinforcement exceeds the value of the reinforcement), so it has the function of active anti-theft.
2. Large bearing capacity: special bottom structure is adopted at the bottom, which can increase the stress area by more than ten times or even dozens of times. The continuous reinforced fiber is used to ensure that the fiber and glass fiber cloth are integrated into one, so that the product has sufficient bearing capacity.
3. Long service life: through the use of high-performance resin, glass fiber and special production process formula, the penetration of resin in glass fiber is ensured, and the adhesion between the two is greatly enhanced, so that the material will not produce internal damage under cyclic load, thus ensuring the service life of the product and the same advantages of other resin composite well covers. The disadvantages of poor adhesion are eliminated.
4. Beautiful and practical, high grade: according to the needs of high-end customers, we can make the personalized design of complex logo and various colors on the surface of the same manhole cover to make the pattern delicate and colorful. And can be made according to customer needs and all kinds of stone pavement with the same imitation stone surface and color.
5. High temperature / low temperature resistance, good insulation performance, strong corrosion resistance: the product is corrosion-resistant, without metal additives, which has a real sense of insulation effect. It can be used in complex, changeable, harsh and demanding places. The products are tested by the relevant authoritative testing organizations, and have obvious acid and alkali resistance, corrosion resistance and anti-aging ability.
6. Environmental protection, anti-skid and low noise: the product will not skid, harsh noise and opposite phenomenon after rolling. At the same time, due to the light weight of the product and the precise closure of the cover and seat, the problems of "jumping, swinging, ringing and shifting" of other manhole covers are overcome.
The particularity of the composite manhole cover lies in the particularity of the material. Adopting the polymer composite material, the material itself has no secondary use value, which plays the role of natural anti-theft and directly solves the problem of manhole cover theft. The composite manhole cover is light in material and can save cost in the process of installation and maintenance.
