INTRODUCE
Fiber reinforced resin matrix composite manhole cover
Composites are materials with new properties composed of two or more materials with different properties by physical or chemical methods. Different materials learn from each other and produce synergistic effects, so that the comprehensive properties of the composite materials are better than the raw materials and meet different requirements!
The fiber reinforced resin matrix composite well cover produced by our company is made with unsaturated polyester resin as the matrix material, steel fiber (reinforcement framework) as the reinforcing material, supplemented by certain filler and curing agent, and hot pressed by hot pressing die machine for thermal insulation and demoulding.
Fiber reinforced resin matrix composite manhole cover has the advantages of high polymerization degree, high density, good impact and tensile strength, wear resistance, corrosion resistance, no rust, no pollution and maintenance free
Hot dip galvanized angle iron outer frame
WELL COVER ADVANTAGE
—————
1. Strong anti-theft performance
2. Large bearing capacity
3. Long service life
4. Beautiful and practical, high grade
5. High / low temperature resistance, excellent green resistance and strong corrosion resistance
6. Environmental protection, anti slip and low noise
The manhole cover produced by our company is made of unsaturated resin, steel fiber and other materials and reinforcement framework. After compounding by special production process, it is molded at high temperature for one time. 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. Therefore, it has the function of active anti-theft, and the problem of urban black hole caused by stealing the manhole cover will be solved.
Steel fiber and steel frame provide a dense and tight carrier structure for unsaturated polyester resin. After high temperature molding, the material mixture can provide sufficient bearing capacity for the whole well cover. The relevant product quality supervision organization conducted load and impact strength tests on the well cover produced by our company, and found that its load force and impact strength exceeded that of the ordinary well cover.
By adopting the special production process formula with high-performance resin as the matrix, the penetration of the resin in the steel fiber is ensured, the adhesive force between the two is greatly enhanced, and the material will not produce internal damage under the action of cyclic load, so as to ensure the service life of the product. The service life is more than 20 years, which is twice that of the cast iron well cover.
According to the needs of high-end customers, the personalized design of complex logo and multiple colors on the same well cover surface can be made to make the pattern delicate, bright and clear. And according to customer needs, we can make all kinds of imitation stone surfaces and colors that are the same as all kinds of stone pavement.
The product is corrosion-resistant, non-toxic and harmless, and has good insulation performance. It can be used in complex, changeable, harsh and demanding places. The products are tested by the relevant authoritative inspection organizations of the state, and have obvious acid and alkali resistance, corrosion resistance and anti-aging ability.
The well cover will not slip, harsh noise and anti friction after rolling. With the characteristics of light weight and close fastening between the cover and the seat, the problems of "jumping, lifting, and displacement" of the general inspection well cover are overcome.
