{dede:global.cfg_gsname/} | Updated: 2020-07-23 08:39:43
SMC manhole cover It is a kind of high strength compound product which is made of unsaturated polyester resin, thickener, initiator, cross-linking agent, low shrinkage additive, filler, internal release agent, colorant and other mixtures impregnated with chopped glass fiber roving by special process, and then formed by high temperature and high pressure liquid pressure.
SMC material is a kind of resin based material, which has excellent electrical performance, corrosion resistance, light weight and high strength mechanical properties. Our country introduced the advanced SMC material production line and production technology from abroad in 1980s. After continuous development and technical improvement in China, it has been applied in many fields in China. Based on the existing SMC sheet technology, our company has improved the glass fiber content of SMC material and further improved the performance of SMC material.
SMC manhole cover has more excellent characteristics
1. High strength bearing, light weight, convenient maintenance.
2. Security.
There is no metal interlayer in the material, so it can be safely used in remote places without monitoring facilities.

3. Prevent noise pollution. Compared with metal manhole cover, the vehicle passing by will produce a lot of noise, especially when the cover seat is loose, it will cause harsh noise. The SMC material can reduce the noise caused by vehicle passing.
4. Super corrosion resistance, wear resistance, antistatic. The service life can reach more than 50 years. It can be used normally from - 50 ℃ to 150 ℃.
5. Solid structure, suitable for all kinds of complex traffic section and construction section.
For rural domestic sewage road excavation, leveling, renovation and other construction technology is complex, the road surface situation is complex, need excavator, roller frequent access, it is difficult to install SMC manhole cover according to the standard process. For the ordinary well cover, it is very easy to damage and hole in this case, which will bring a lot of maintenance cost to the follow-up project operation and maintenance. The SMC well cover can not be damaged in various complex situations because of its excellent performance of pressure resistance and wear resistance.
