Description :

　　IIJDPP30-30MS, JDPP50-50MS plastic false roofSpecific operation methods for internet access:

　　(1) After the fiber mesh enters the working face, the first step is to confirm whether the direction of the mesh is correct and whether the mesh is twisted after unfolding. Then, use a blade to cut off the ropes of the fiber mesh.

　　(2) After unfolding the mesh, use the steel wire rope on the manual winch to pass through the steel wire rope on the working face, hook up the edge of the mesh, shake the winch, lift the fiber mesh edge, and connect it with the steel wire rope on the working face with a networked wire.

　　JDPP30-30MSPlastic fake roofStrong anti-corrosion ability Anti aging.JDPP50-50MS plastic false topEasy to construct and transport.Plastic false roof net for underground coal minesRelatively soft, it is not suitable for scratching workers during construction, and has the advantages of easy curling, bundling, cutting, and light weight, making it easy to transport, carry, and construct underground

　　JDPP30-30MS, JDPP50-50MS plastic false roofFeatures:

　　Plastic false roof net for underground coal minesIt is a grid structure formed by using polypropylene as the main raw material, flame retardant and anti-static technology treatment, and adopting biaxial stretching method to form a whole structure.

　　1. Friction does not easily generate static electricity. In the underground environment of coal mines, the average surface resistance of plastic mesh is below 1 x 109;

　　2. Good flame retardant performance. In an open flame environment, it only melts and does not burn, even if it burns for no more than 10 seconds before extinguishing;

　　3. Easy to wash coal. The density of this plastic mesh is around 0.92, which is lower than the density of water. During coal washing, the broken mesh floats on the water surface and is easily washed away;

　　6. Both vertically and horizontally have strong load-bearing capacity. After extrusion and stretching processes, the molecular structure of the plastic mesh is rearranged, and the tensile strength of the material is 2-3 times that of before stretching. The ribs formed by biaxial stretching are perpendicular to each other, which allows the pressure applied to the mesh surface to be effectively transmitted to the surrounding ribs through the nodes, greatly improving the overall pressure bearing capacity of the mesh surface. When external force is applied to a certain tendon (or rib), it also evenly distributes the external force to other tendons (or ribs), reducing the concentrated load-bearing capacity of the single tendon (or rib) Therefore, it is not easy to cause rib breakage. Due to the fact that this plastic mesh is biaxially stretched rather than woven, the creep of the mesh holes is small, and the mesh size is uniform, which can effectively prevent the falling of broken coal blocks and protect the safety of underground workers and the operation of mining cars.
