Composite resin trench cover is a special covering equipment for road drainage. Common materials are cast iron and composite resin. Resin drain covers have gradually replaced other materials. It can be used for 20 to 30 years, its size is designed according to its location, high load, excellent drainage effect and unique anti-theft function.
Cast iron trench cover plate has certain bearing capacity, but it is easy to be corroded, rusted, broken, stolen and other defects. In the process of installation and use, anti-corrosion and anti-theft treatment should be done well, which requires certain maintenance costs, heavy weight, transportation costs and labor costs. What are the characteristics of resin composite trench cover? The water leakage area is large, the toughness is strong, the bearing capacity is high, the resilience is good, corrosion resistance, high temperature resistance, fire resistance, anti-static, the material has no recycling value, even if there is steel bar, the cost of taking out the steel bar is very high, no need; the appearance design is also very extensive, the foundation can meet all the needs of the user. It is suitable for gas stations, chemical plants and other flammable, explosive and corrosive dangerous places.
According to the new building materials industry standard of the people's Republic of China (Standard No.: jc889-2010), steel fiber, concrete and manhole cover are divided into four levels according to their bearing capacity.
A. It is used for special passageways and sites such as airports or highways where helicopters can take off and land.
B. Urban roads, highways and parking lots for motor vehicle driving and parking.
C. It is used for slow lane, residential area passageway and sidewalk.
D. It is used in the residential area and site where motor vehicles cannot drive and park.
1. Strong impermeability: the well cover of resin composite material is made of underfull machine resin glass fiber and reinforcement framework, which is compounded by special production process and molded once at high temperature. The material has no recycling value. Take out the steel bar, the cost exceeds the value of the steel bar. Therefore, it has the function of active anti-theft.
2. Large bearing capacity: the special pot bottom structure is adopted at the bottom, which is the continuous reinforced fiber used to ensure the integration of fiber and glass fiber from the material. So that the products have enough bearing capacity, and meet or exceed the quality standards of our well cover industry.
3. Long service life: through the use of high-performance resin, fiber and special production distribution, the penetration of resin in the glass fiber is ensured, greatly increasing the adhesion between the two
4. The high polymer molding well cover produced by our company is made of high load (50kn-900kn) materials such as BMC / SMC resin, quartz sand and heavy calcium, and reinforced framework, which is molded by high temperature and high pressure at one time. This product has the advantages of high density, high hardness, high pressure, light weight, corrosion resistance, anti-aging, beautiful appearance, artistic pattern or unit name.
