The plastic protective net used in coal mines is a double-resistant plastic net independently developed by our company. This product is easy to construct, low cost, safe and beautiful. Its main features are that friction does not easily generate static electricity, good flame retardant performance, strong anti-corrosion ability, easy construction and transportation, easy coal washing, and strong vertical and horizontal load-bearing capacity.
Product Features
This product is made of polypropylene as the main raw material. After being treated with flame retardant and antistatic technologies, it is a square grid with an overall structure formed by biaxial stretching.
, friction is not easy to generate static electricity. In the underground coal mine environment, the average surface resistance of plastic mesh is below.
, good flame retardant properties. It only melts but does not burn in an open flame environment. Even if it burns no longer than the longest distance from the fire, it will be extinguished.
, convenient for washing coal. The density of this kind of 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 anti-corrosion ability and anti-aging.
, easy 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 easy to curl and bundle, cut and light in specific gravity, making it easy to transport, carry and construct underground.
, has strong load-bearing capacity in both vertical and horizontal directions. After the plastic mesh is extruded and stretched, its molecular structure is rearranged, and the tensile strength of the material is twice that of before stretching. The ribs and ribs formed by bidirectional stretching are perpendicular to each other. This structure allows the pressure exerted on the mesh surface to be effectively transmitted to the surrounding ribs through the nodes, thereby greatly improving the overall pressure-bearing capacity of the mesh surface. When an external force is applied to a certain rib (or rib), the external force will be evenly distributed to other ribs (or ribs), reducing the concentrated interception capacity of a single rib, making it less likely to cause the rib to break. Second, because this 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 of underground workers and the operation of mine cars. safety.
