Coal mine with fake plastic composite roof Network Usage: The product is mainly used for coal mine seam slice off the top and help protect mined, but also can be used as anchor roadway, supported roadway, roadways, and other roadway Shotcrete The support material. for false roof, be sure to double or more in combination. There is also used for other mine roadway engineering, slope protection works, underground civil works and road works traffic anchor, strengthen the material is woven plastic mesh and steel mesh best alternative. Plastic mesh when the product model and symbol: Plastic network model by product type, material, longitudinal and transverse tensile strength grade, flame retardant anti-static, vertical and horizontal edge mesh class into five parts, specifically marked as follows: JD GS + PP 40MS (JD behalf of off the top; GS + PP, said material for steel + PP; 40 indicates a single network with pull-off force, in units of kN (KN); M represents a composite network; S represents retardant antistatic) execution Standard: Q / ZTJ · TG01-2006 "coal mine with a plastic off the top," coal mine with a plastic off the top with a flame retardant, antistatic properties, high tensile strength, low creep and other characteristics. Specifications indicators as follows: coal mine with a plastic off the top mass per unit area, size and offset projects JD PP50-50MS width: m 4.0 or 5.0, but also according to user requirements width error: m 0 ~ + 0.20 mesh side length : mm 40 (± 5) × 40 (± 5) coal mine with a plastic off the top of the physical and mechanical properties Item Unit JD PP50-50MS 1 per meter vertical pull-off force KN / M ≥50 2 per meter of the lateral pull-off force KN / M ≥50 3 longitudinal elongation at yield% ≤25 4 promote long transverse yield rate% ≤25 5 sticky pads limit the peel force N ≥120 *************** **************************** Company: Shandong Xiang New Material Co., Ltd.
