The company's high-strength composite material inspection manhole cover is made of unsaturated resin-based chemical raw materials, supplemented with steel reinforcement ribs. After high temperature molding, the anti-theft resin manhole cover is a new type of environmentally friendly product. This product integrates new technology, new materials and new processes, and greatly breaks through many shortcomings of traditional manhole cover products. It is currently an alternative to cast iron and cement manhole cover management.
Anti-aging performance: Put the sample in a temperature and humidity control device, use a 60 ℃ ± 5 ℃ xenon lamp and rain for 500 hours, the Qinghai resin manhole cover, the flexural strength change is:> 3 friction coefficient: use the cover surface and rubber to directly rub 5 hours, with a coefficient of> 0.35 and a long service life: through the use of high-performance resins, glass fibers and special production process formulas, to ensure the penetration of resin in glass fibers, greatly enhance the adhesion between the two, and make the material circulate. Under the action of load, no internal damage occurs, thereby ensuring the service life of the product and the same superiority of other resin composite manhole covers. Eliminate the disadvantages of poor adhesion.
The main differences between resin cover and resin manhole cover:
1 Resin cover plate and resin material manhole cover are made of the same material and the same production process. The products produced by our company guarantee the quality. Green resin manhole cover, please rest assured to buy.
2 The difference between the two is that in the environment of use, circular resin manhole covers are mostly used in rainwater wells, new resin manhole covers, and sewage wells, while resin cover plates are mostly used for cable trench covers
Board these aspects.
3 The shapes of the two are different. The compoiste manhole covers are mostly round, while the resin cover plates are mostly square.
