Mine grille Product Uses: off the top of the coal mine grassroots network, which can effectively prevent the mine road collapse and cracks. The product is mainly used as a guard to help in the mining of coal mine, also as anchor roadway, supported roadway, roadway and other roadway anchor spray supporting materials. , Be sure to leave the top bunk above joint use. Polypropylene as the main raw materials, and after a flame retardant, antistatic technical processing, to take the square grid of the overall structure formed by a two-way stretching method. Polypropylene as the main raw material, adding a variety of additives, drawn into the band, woven mesh, mesh into a regular hexagon intersect every three layers, are closely linked, pull evenly dispersed to the six directions, this structure dispersion conducive to vertical heavy loads, network and networking rope connected as a whole, depending on the coal mining process can be divided into hierarchical mining and total mining. Product packaging: packing tape strapping packaging mining grille features: 1, mine grille friction is not easy to generate static electricity. In the coal mine environment, the average surface resistance of plastic mesh in less than 1 × 109Ω; mine grille good flame retardant properties. Only melted in the open flame environment does not burn, even if burning from the fire no longer than 10s Jimie; mine grille easy coal washing. This plastic mesh density of about 0.92, less than the density of water, coal washing process, broken mesh floating in the water, easy to wash off; mine grille corrosion resistance and anti-aging. 5, mine with a grid to facilitate the construction and transportation. Plastic mesh is relatively soft, and should not scratch the workers in the construction, but also has the advantage of easy curl bundling, tailoring and light weight, thus facilitating the underground transport, carry and construction; 6, the vertical and horizontal direction have a strong bearing capacity. After plastic net after the treatment of the extrusion and stretching process, its molecular structure is re-orientation, the tensile strength of the material is 2-3 times before the undrawn. Biaxially stretched to form the ribs and the ribs are perpendicular to each other, this structure makes the pressure applied to the mesh surface through node effectively passed around the ribs, thereby greatly improving the overall pressure capability of the mesh surface. When the external force is applied to a one rib (or ribs), and will also be the external force is uniformly dispersed to the other rib (or ribs) reduces a single centralized carrying capacity, and therefore difficult to cause the breakage of ribs. This plastic net is a two-way stretch non-woven mesh creep amount is small, and the mesh size is uniform, can effectively prevent the drop of the crushed coal and protect the safety of operation of the downhole safety of workers and scavengers. Mining geogrid acid corrosion, not aging, long service life, avoid rust easily shortcomings with barbed wire. According to user requirements, produce a flame retardant, antistatic, double anti-type and special pull-products, this product is light weight, easy to transport and install underground workers can reduce labor intensity, than the use of metal network is easy to operate, while the price per square meter is only the metal mesh of 1/2 or 1/3, which can greatly speed up the production schedule, reduce production costs, increase profits and improve the economic efficiency of enterprises, and to ensure production safety. Mining geogrid coal mine support features: 1, with a flame-retardant and antistatic properties, in line with the requirements of coal mine safety regulations ". 2, the compressive strength of the product, wear-resistant, corrosion-resistant, can replace metal diamond mesh and other supporting material, is a good replacement products. Effect of branched Square, rectangular mesh of the product, the net stocks intersection fixed, mesh deformation, so that nursing help nursing top even by force, to meet the mining needs of the mining depth increases and crushing work to improve the supporting effect. 4, light weight, shipping, construction is convenient. 5, recyclable, reduce the waste of resources, to achieve the purpose of savings and consumption reduction.
