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 use value, and it is very difficult to take out the reinforcement (the cost of taking out the reinforcement exceeds the value of 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. And meet or exceed the national standards.
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 SMC manhole covers. The disadvantages of poor adhesion are eliminated.
4. And can be made according to customer needs and all kinds of stone pavement with the same imitation stone surface and color.
5. HThe products have been tested by the relevant national testing institutions, with obvious acid and alkali resistance, corrosion resistance and other indicators have reached and exceeded the national standards.
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.
Summary: resin composite well cover is made of polymer composite material, which has no recycling value. After the use of resin manhole cover, the problem of city black hole caused by stealing manhole cover will be solved.
The SMC manhole cover service life is more than 20 years, which is twice as much as that of cast iron manhole cover, and the price is only 80% of that of cast iron manhole cover. At the same time, this kind of well cover has the characteristics of insulation and no noise
