Gas drainage sealing agent gas drainage sealing agent belonging to two-component material, it is mixed by a certain percentage after curing chemical reaction generates a rigid polymeric material, when used without an object to be sealed, container products , thickness and shape effects can be blocked immediately after casting, does not affect cure. The product high strength, foam adjustable magnification, with moisture, corrosion resistance, low temperature resistance and good sealing performance, but with less material, easy to carry, sealing quickly (five minutes or so), saving time and effort. Same time as the material has a certain degree of flexibility and toughness, compression deformation is not broken. In the dynamic pressure or prolonged drainage area be more unique advantages, ideal for gas drainage hole closed and blocked. Gas drainage sealing agent applications: two-component gas drainage sealing agent belongs polymer materials, gas drainage sealing agent mixed by a certain percentage after curing chemical reaction generates a rigid polymeric material, gas drainage sealing agent when used without an object to be sealed, container products, thickness, shape effects can be blocked immediately after casting, does not affect the product solidified. gas drainage, high strength sealing agent, foam adjustable magnification , with moisture, corrosion resistance, low temperature sealing performance and good features, but with less material, easy to carry, sealing speed (about 5 minutes) effort, time, while the materials have a certain flexibility and toughness, compression deformation not broken, the dynamic pressure drainage area or a long time, more unique advantages, ideal for gas drainage hole closed and blocked. ambient gas drainage and sealing agent Scope: This product is suitable for dry, low spontaneous combustion coal mine. Gas drainage sealing agent parameters curing time: 30S-300S Compression strength: (Mpa) ≤ 20 Foam Density (kg/m3) 50-60 Bond strength: (Mpa) ≤ 15
