The plastic security network used underground in the coal mine
Product Introduction
The plastic security network used underground in the coal mine is a kind ofdouble-resistant plastic networkdeveloped independently by our company. The product is convenient to operate with the advantage of low cost and beautifui outlook.The main characteristic is that it is easy to static friction and has good flame retardancy, anti-corrosion and it is convenient in the construction and transport to facilitate coal washing both vertically and horizontally to the carrying capacity.
Product Feathers
The product is based on polypropylene as the main raw material, through flame-retardant, anti-static treatment, the bi-oriented approach taken by the formation of the overall structure of the grid network.
1. Attrition is not easy to cause static friction.In the coal mine environment, the average surface resistance of plastic net is below1 x**9Ω
2.Good flame-retardant performance. It can not only melt but also not burn in the fire environment even if the fire burning from the *0s up to the put out.
3. It can facilitate coal washing.This plastic net density is about 0.*2, less than the density of water. In the coal washing process, the broken mesh floating in the water, easy to wash off.
4.Strong anti-corrosion, anti-aging.
5.Facilitate the construction and transportation. The plastic network is relatively soft so that it is noe easy to scratch workers in the construction. And also it is easy to curl bunding, tailoring, and has the advantages of light weightand therefore easy to underground transport,carry and construction.
6.Have strong carrying capacity in vertical and horizontal direction.After extrusion and stretching process of the plastic, the molecular structure of materials is re-orientated. The tensile strength of the material is **3 times than before. The formation of two-way stretch tendonsand rib each other vertically, this structure enables the surface to exert pressure on the networknode through effective transfer to the four ribbed tendons, thus greatly enhance the network capacity to face the overall pressure. When an external force is imposed to a certain tendons, external uniform will also be distributed to other bars on the lower concentration for a single out-off ability, which is not eaasy rib fracture caused by gluten. Second, as a result of this network is a two-way stretch plastic rather than woven, the small mesh creep and uniform mesh size can effectively prevent the failing pieces of coal to protect the safety of mine workers and mine cars running.
Product Function
The product is mainly used at the time of protection for the exploitation of coal mine and also can be used as anchorof roadway, roadway support, anchor spray roadway roadwayand other material support. When used in the fake top, be sure to useddouble-deck joint above.
