BMC polymer resin molded manhole cover

Product introduction

The new BM C polymer resin molded composite material for manhole cover produced by our factory, adhering to the concept of "green environmental protection", adopts chemical raw materials such as unsaturated resin and glass fiber, supplemented by reinforcement bars, and is composed of high temperature and high pressure.

Product advantage

(1) Anti-theft

The materials used in this product have no recycling value, so they will not be stolen, fundamentally eliminate the phenomenon of urban traps and road black holes, and protect people's lives and property.

(2) Light weight, easy to use, moderate price

The use of high-strength composite materials as raw materials, convenient and practical, the weight is about half of cast iron products, easy to transport and construction, the price is cheaper than cast iron manhole covers, and the product promotion is rapid.

(3) High and low temperature resistance, corrosion resistance, anti-aging

The performance of the raw materials used is stable, and after testing according to the high and low temperature resistance, corrosion resistance and anti-aging test standards formulated by the state for related products, the product performance indicators meet the standards and the service life is long.

(4) Large payload, and no impact noise

This product not only has the strength of cast iron manhole cover, but also has the toughness of cast iron manhole cover, with high performance and large bearing capacity. This product adopts high temperature molding, cover, seat joint gap is small, overcome the manhole cover "running, jumping, ringing" problem, improve the road capacity and driving.

(5) Strong color plasticity

Products can be according to customer requirements to deploy color, plate typing, beautiful design, scientific.

Product application scope

Suitable for streets, industrial parks, residential areas, city squares, underground garages, colleges, factories and mines, farms, communication, fire, gas, chemical, water supply and drainage of all underground facilities of the road or site of the well exit and trees and flowers fertilization and maintenance pond.

Product application unit

Water company, municipal company, real estate company, gas company, Unicom company, Netcom company, mobile company, Tietong company, electric power company, factory and mining enterprises, park colleges and universities.

Product introduction

SMC is a kind of raw material for the molding of the sandwich core. The core material is a sheet material of short-cut roving without twist, impregnated polyester resin paste, covered with polyvinyl film on both sides. When in use, it can be demoulded to obtain the product by adding it to the mold that has been heated, and pressurizing and holding the product takes time.

SMC polymer resin molded manhole cover

Product advantage

First, SMC resin material has all the advantages of BMC material.

Second, SMC has quite good formability, very suitable for large-size products and products with complex modeling structure, and the size of the formed parts is stable.

Third, high productivity, suitable for mass production.
