What is a Resin Composite Manhole Cover?

What is a resin composite Manhole Cover?
The oversized features of the resin Composite Manhole Cover are made of a polymer composite without any recycling value. After the promotion of the Resin Manhole Cover, the problem of theft of the manhole cover and the black hole in the city will be solved. Unlike the manhole cover on the market, it is extruded by a hydraulic press and has the ability to withstand high impact strength. The resin composite manhole cover is made of glass fiber and resin as a base material and is made of high temperature and high-pressure auxiliary material such as a curing agent and a promoter. The weight is two-thirds lighter than the cast iron manhole cover, but the service life is more than 20 years, twice the cast iron manhole cover, but the price is only 80% of the cast iron manhole cover. At the same time, the composite manhole cover also has the advantages of a lightweight, high strength, excellent performance, not easy to break, simple molding, low rolling noise of the automobile, good chemical corrosion resistance, good acid, and alkali resistance, and beautiful appearance. Usually, it is round and can be used for green belts, sidewalks, motor vehicles, and docks.
Polymer composite resin manhole cover products have the following characteristics:
1, anti-theft performance: resin composite manhole cover using a special production process, made of unsaturated resin, glass fiber, and other materials and steel frame. After high temperature grinding and forming, the material has no recycling value. It is very difficult to remove the steel bars. The cost exceeds the value of the steel bar) and therefore has the function of active anti-theft.
2. Large carrying capacity: the bottom is made of a special pot bottom structure, which is ten or even dozens of times the force area. The continuous reinforcing fiber yarn used maintains the fiber filaments and the fiberglass cloth together in one material, giving the product sufficient load-carrying capacity. And meet or exceed the standard.
3, long service life: the use of high-performance resin, glass fiber and special production process formula, to ensure the permeability of the resin in the glass fiber, the adhesion between the two is greatly improved, so that the material is not affected by the cyclic loading. Internal damage is created to ensure product life and the superiority of other resin composite manhole covers. Eliminate the disadvantage of poor adhesion.
4. Beautiful and practical, high grade: According to the needs of high-end customers, we can make complex LOGO and multi-color personalized designs on the same manhole cover surface, making the pattern delicate, bright and clear. According to the requirements of customers, we can make a variety of imitation stone surfaces and colors, the same as all kinds of stone pavement.
5. High temperature/low-temperature resistance, good insulation performance and strong corrosion resistance: the product is corrosion resistant and harmless. Without metal additives, it has a real insulation effect. It can be used in complex, diverse and demanding places. The product has been tested by relevant testing institutions and has obvious acid and alkali resistance, corrosion resistance, anti-aging, and other indicators have reached and exceeded the standard.
6. Environmental protection, non-slip, low noise: This product will not slip, and there will be no harsh noise and reversal after the vehicle is crushed. At the same time, due to the lightweight of the product, the cover and the seat are fastened, which overcomes the problems of other inspections of the manhole cover "jumping, squeaking, ringing, shifting".
