SMC manhole cover
SMC manhole cover is a kind of manhole cover which is molded by highg temperature press with composite materieals(unsaturated resin + glass fiber + calcium powder + filler, etc.), which is also called composite manhole cover.
The composite manhole cover is a type of environmental protection manhole cover, which is in the international market. Why can manhole covers be made so beautiful, and they are not afraid of corrosion and theft.
Next, we will introduce the characteristics of the SMC manhole cover
1 strong anti-theft performance: the resin SMC 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.
3. Long service life: through the use of high-performance resin, glass fiber and special production process formula, the role 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 the 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. Beautiful and practical, high grade: according to the customer's needs, we can make the personalized design of complex logo and various colors on the surface of the same manhole cover, so that the pattern is delicate and the color is bright and clear. 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 and strong corrosion resistance: the product is corrosion-resistant and has no metal additives, which has a significant insulation effect. It can be used in complex, changeable, harsh and demanding places. The product has been tested by relevant testing institutions, and has obvious acid and alkali resistance, corrosion resistance and anti-theft.
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, the cover and seat are tightly closed, which overcomes the problems of "jumping, swinging, ringing and shifting" of other manhole covers.
