Why SMC Manhole Cover Also called Epoxy Manhole Cover?

Why is the SMC Manhole Cover also called epoxy manhole cover?

SMC epoxy manhole cover is improved according to SMC production process and raw material formula, and epoxy resin is added as a resin material with excellent mechanical properties, so that the produced SMC material has stronger mechanical properties after molding. At the same time, the molding process has been improved accordingly. This improvement can improve the bearing level of the molded manhole cover under the same mold. The molded product has a lighter weight and higher strength. However, for the production process of the ordinary SMC manhole cover, the production cost is high and the production time is long. Although epoxy resin SMC manhole covers are costly, they still have superior cost performance.

1.fiber-reinforced thermosetting composite material using unsaturated polyester resin as a matrix, also known as a bulk molding compound (BMC), is made by pressing molding technology and is a new type of environmentally friendly cover plate. The Composite Manhole Cover adopts high temperature and high pressure one-time compression molding technology, which has high polymerization degree, high density, good impact resistance and tensile strength, and has the advantages of wear resistance, corrosion resistance, no rust, no pollution and no maintenance.

2. Generally refers to the use of glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix. A reinforced plastic made of glass fiber or its products as a reinforcing material, called glass fiber reinforced plastic, or glass fiber reinforced plastic, is distinguished from tempered glass. Because of the variety of resins used, it is called polyester fiberglass, epoxy glass reinforced plastic, and phenolic glass reinforced plastic. Light and hard, non-conductive, stable performance. High mechanical strength, low recycling, corrosion resistance. Machine parts and automobiles, ship casings, etc. can be manufactured instead of steel.

China standard manhole cover


The Resin Manhole Cover can be so popular. Basically, its comprehensive performance and economic indicators have surpassed the cast iron manhole cover, and it can also solve the problem of theft of the cast iron manhole cover, while reducing resource consumption, with important economic and social value, resin. The manhole cover has the advantages of light weight, high strength, simple molding, low noise of car rolling, good chemical corrosion resistance, good acid and alkali resistance and beautiful appearance. It has the advantages that the cast iron manhole cover does not have. The surface of the resin inspection manhole cover is beautifully designed and the color is bright. Adjustable, beautifying the urban environment, easy to use, light weight, no inspection value of resin inspection manhole cover, natural anti-theft, resin inspection manhole cover can be used at -50 °C through scientific formula, advanced technology and perfect technical equipment. -+150°C normal use in the environment, acid and alkali resistant, corrosion resistant, wear resistant, resistant to vehicle rolling, long service life, in line with resin manhole cover standards.
