Wiping will not easily generate static electricity. In the underground coal mine environment, the average surface resistance of plastic mesh is below.
Good combustion performance. The flame retardant properties specified by coal industry standards can be achieved respectively.
In coal washing. The density of the plastic mesh is on the right, which is smaller than the density of water. During the coal washing process, the broken mesh pieces float on the water and are easily washed away.
Strong corrosion ability and anti-aging.
For construction and transportation. Plastic mesh is relatively soft and is not suitable for scratching workers during construction. It also has the advantages of being easily curled and bundled, cut for mining grids, and light in specific gravity, making it easy to transport, carry, and construct underground.
It has strong load-bearing capacity in both transverse directions. Because this kind of plastic mesh is bidirectionally stretched rather than woven, the mesh creep is small and the mesh size is uniform, which can effectively prevent the falling of broken coal and protect the safety and safety of underground workers. Mine car operation safety.
