The product is from a variety of polymers designed for underground strictly necessary coal and rock reinforcement research and development, seam conditions of use without restrictions. Using a dedicated injection pump and a mixing gun, and react with the resin and catalyst are mixed at a volume ratio of 1:1. Hair seasonal low viscosity, good fluidity, can penetrate into the tiny cracks, swelling and hardening, great strength, more than the hardness of coal and waste rock reinforcement and closed applicable areas. Because of its good adhesion, high compressive strength, ductility and toughness after injection to improve the intensity of coal and rock, meet the requirements. Scope: reinforcement of roadway coal face reinforcement pillar reinforcement and plugging air methane drainage hole sealing Features: low viscosity, flame retardant anti-static, has a good permeability quickly reach optimal physical strength and good toughness, shorten the duration of construction fast simple operation antistatic flame spread of the basic ingredients of the Technical Data AB Appearance light yellow liquid brown liquid Viscosity (25 ° C) 200 to 400 200 to 400 using the ratio of 1:1 (V) reaction time (s) 40 to 120 maximum compressive strength Mpa> 50 flame retardant properties retardant
