Description :

　　Steel plastic composite mesh with high false top tension for coal mines, 4 steel wire steel plastic mesh

　　Steel plastic composite mesh false roof, 4 steel wire steel plastic mesh, manufacturer of mining steel plastic composite mesh false roof, mining plastic protective net

　　Steel plastic composite mesh false roof for coal minesIt can be widely used in construction, foundation engineering, road and mine protection, as well as coastal defense and river embankment slope protection. The application field is extremely broad and is positioned for the protection of coal mine tunnels.

　　In order to prevent coal and stone collapse and gradual collapse, protective measures must be taken in accordance with regulations for the spatial areas formed during coal mining and the tunnels entering each excavation point. The existing equipment mainly uses metal mesh, but coal mines have reported that metal mesh is bulky and prone to corrosion, making it not an ideal protective equipment. The mining steel plastic composite false roof mesh can achieve the same effect as a metal mesh in terms of tensile strength, load-bearing capacity, and extension, and has unparalleled advantages in corrosion resistance and lightweight. Its application is very obvious and suitable for the protection and renovation of coal mine tunnels.

　　1、 Performance of Steel Plastic Composite Mesh False Roof for Coal Mines:

　　Steel plastic composite mesh false roof for coal mines is a new type of protective net specifically designed for coal mines. It adopts a structure of modified plastic wrapped high-strength cold drawn steel wire, focusing on improving its comprehensive performance while ensuring strength requirements. This new product has the following major advantages compared to traditional diamond shaped mesh and warp and weft mesh:

　　1. The elongation rate of the steel plastic composite mesh false roof used in coal mines is less than 5%, effectively avoiding the phenomenon of "net pockets" in actual use and overcoming the unsafe factors of underground use;

　　2. The surface of the steel plastic composite mesh false roof used in coal mines is made of corrosion-resistant modified plastic, which will not rust or fail due to corrosion after long-term use, ensuring long-term protection effect;

　　2、 The deviation of the mesh size of the fake roof of the steel plastic composite mesh used in coal mines is shown in Table 1; The length, width, and deviation of the false top net are shown in Table 2

　　The main technical indicators of the steel plastic composite mesh false roof used in the three coal mines are as follows:

　　1. Unilateral ultimate tensile strength ≥ 4800N;

　　2. The maximum elongation of the product is ≤ 5%;

　　3. Node ultimate peeling force ≥ 200N;

　　4. The product has a flame extinguishing time of ≤ 10s (flame retardant performance)

　　5. The surface resistance value of the product is ≤ 1 × 109 Ω (anti-static performance);

　　6. Mesh size 50 × 50mm~60 × 60mm (adjustable in one direction);

　　7. Product width 0.8m~4.0m (adjustable)
