SMC manhole cover is also called sheet molding manhole cover. It is made of unsaturated polyester resin, thickener, initiator, cross-linking agent, low shrinkage additive, filler, internal release agent, colorant and other impregnated chopped glass fiber. A high-strength composite product of roving sheet molding compound formed by a special process and high temperature and high pressure hydraulic forming.
SMC material is a kind of resin-based material, which has excellent electrical properties, corrosion resistance, light weight and high strength mechanical properties. In the 1980s, China introduced foreign advanced SMC material production lines and production technology. After continuous development and technical improvement in China, it has been maturely applied in many fields in China. Based on the existing SMC sheet technology, our company has improved the glass fiber content of the SMC material and improved the performance of the SMC material. The SMC manhole cover made of SMC material produced by our company has more excellent characteristics.
1. High strength bearing, light weight and convenient maintenance. The density of this product is only 1/4 of that of steel, but the strength can exceed the strength of steel through special processing. Widely used in urban and rural roads, airports, gas stations, telecommunications, communications, water, gas and other important transportation roads.
2. Security and anti-theft. There is no metal interlayer in this material, which has no stealing value, so it can be safely used in remote and unmonitored facilities.
3. Prevent noise pollution. Compared with the metal manhole cover, the passing of the vehicle will generate 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 passing vehicles.
4, super corrosion resistance, wear resistance, antistatic. The service life can reach more than 50 years. It can be used normally at -40 ℃ to 100 ℃, and its service life is more than 5-10 years longer than the ductile iron manhole cover; it is more than 30 years longer than the steel fiber manhole cover and BMC manhole cover.
5. The non-hollow structure makes it suitable for various complicated traffic sections and construction sections. The excavation, leveling, and renovation of rural sewage roads are complicated in construction technology, and the road surface
The situation is complicated, requiring frequent access of excavators and rollers, and it is difficult to install manhole covers according to standard procedures. For ordinary manhole covers, in this case, manhole cover damage and holes are extremely prone to occur, which will bring great maintenance costs to subsequent project operation and maintenance. The SMC manhole cover can not be damaged under various complicated conditions due to its excellent pressure resistance and wear resistance.
