coal mine plastic grids

1.coal mine plastic grids material is pp (polypropylene) 2.coal mine plastic grids not easy to produce static when friction Plastic grids for coal mine is mainly consisted of Polypropylene, through the special processing of anti-static and fire resistance, its characters as following:A. Not easy to produce static when friction. Under coal mine, the resistance mean value of girds is 1×109ΩB. Good ability of fire resistance. In the environment of 760°C, only melting, no fire, it will extinguish as soon as the grids left flame if it fire.C. Convenient to wash coal. The density of this grids between 0.89 and 0.91, below the density of water, the broken rids will float on the water during washing coal, easy to be wash out.D. Good performance of anti-corrosion.E. Convenient to construction and transport. It is not easy to hurt wokers because this kind of grids is sofe relative, convenient to pack and cut out, easy to transport under mine and construction.  This products mainly used in coal mine as ceiling and shield, also can be used to protect laneway when mining coal.
