Hole sealing agent belongs to the two-component materials, which in a certain proportion of mixed reaction and curing of the generated after a hard polymer material, not sealed when using object, the influence of the container products, thickness, shape, can be blocked immediately after pouring, curing does not affect the product.The product high strength, expansion ratio is adjustable, moistureproof, corrosion resistant, low temperature resistance, and the characteristics of the sealed performance is good, and less material, easy to carry and hole sealing quickly (five minutes), save time and effort.At the same time, because the material has certain elasticity and toughness, compression deformation is not broken.In the dynamic pressure area or long time more when drainage has unique advantages, the most suitable for gas drainage hole closed and sealed.
Compression strength ：(Mpa)≤20
Foaming density (kg/m3)50-60
Sealant Application Method & Range
Hole sealing agent use environment and the scope of application: this product is suitable for dry, low coal seam spontaneous combustion mines.
Sealed or blocked, there can be no flake oil, coal or rock hole hole of debris to clean up as soon as possible.
