Epoxy resin well cover is a kind of resin material with excellent mechanical properties, which uses SMC sheet and epoxy resin, so that the SMC composite well cover produced can have better mechanical properties. In the same mold, the well cover with epoxy resin material has higher bearing capacity, better strength and toughness than that without epoxy resin material. But for the common SMC well cover production process, this kind of production cost is relatively high and time is relatively long, but the overall characteristics and effect of epoxy resin well cover are much better than the traditional well cover.
What are the advantages of epoxy resin well cover over traditional well cover? The fiber-reinforced thermosetting composite based on unsaturated polyester resin, also known as bulk molding compound (BMC), is made by pressing technology, which is a new type of environmental protection cover plate. The composite well cover adopts high temperature and high pressure one-time molding technology, with high polymerization degree, high density, good impact resistance and tensile strength, wear-resistant, corrosion-resistant, rust free, pollution-free, maintenance free and other advantages. It generally refers to the glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix. The reinforced plastics with glass fiber or its products as reinforcement materials are called as glass fiber reinforced plastics or glass fiber reinforced plastics, which should be distinguished from toughened glass. Due to the different types of resin used, it is called polyester glass fiber reinforced plastics, epoxy glass fiber reinforced plastics and phenolic glass fiber reinforced plastics. Light and hard, non-conductive, stable performance, high mechanical strength, less recycling, corrosion resistance. It can replace steel to manufacture machine parts, automobile, ship shell, etc.
The cast iron well cover developed earlier and was cast by pig iron, which has better bearing capacity and weather resistance. The disadvantage is that the production cost is high and the production process pollutes the environment. Once it is broken, it collapses completely and the safety protection function is lost. Part of the production enterprises are just for profit and steal to reduce materials, which makes the bearing capacity of the products unable to be guaranteed. The contact surface between the well cover and the well seat lacks machining, In addition, due to the high recovery value of cast iron well cover, the lawbreakers can see the profit and sell the cast iron well cover to the waste recycling station after stealing and smashing. Especially in recent years, with the rise of steel price, the theft of cast iron well cover is serious.
Resin well covers are so popular that their comprehensive performance and economic indicators have surpassed those of cast iron well covers, and they can solve the problem of theft of cast iron well covers. At the same time, they can reduce the consumption of resources and have important economic and social values. Resin well covers have light weight, high strength, simple forming, low rolling noise, good chemical corrosion resistance, good acid and alkaline resistance and appearance Beautiful and other advantages. It has the advantages that the cast iron manhole cover does not have. The surface pattern of the resin inspection manhole cover is exquisite, the color is bright and adjustable, it beautifies the urban environment, it is convenient to use, light in weight, the resin inspection manhole cover has no recycling value, it is natural anti-theft. The resin inspection manhole cover makes the product positive in the environment of - 50 ° C - + 150 ° C through scientific formula, advanced technology and perfect technical equipment Often used, acid and alkali resistant, corrosion-resistant, wear-resistant, rolling resistant, long service life, in line with the resin well cover standard.
