Mine silent expanders

 Mining, also known as silent expansive controllable cut and broken expanders, static crushing agents, static crack agents, Splitting agent, crack stones and the like. It is a production made by a variety of inorganic materials with high expansion properties of gray powdery material with a non-explosive fragmentation. According apply to different ambient temperature, there are three models: SCA-1 (25 ℃ ~ 40 ℃), SCA-2 (10 ℃ ~ 25 ℃), SCA-3 (-5 ℃ ~ 10 ℃). Their working principle is: with the right amount of water into the fluidized slurry poured directly borehole through hydration reaction, the crystal deformation, resulting in huge expansion pressure (radial stress and cyclic tensile stress over time ) and applied to the hole wall. The expansion pressure is proportional to the reaction time and mine silent extenders, i.e. the longer the greater expansion pressure; cracking time required for the object is inversely proportional to ambient temperature, i.e. the higher the temperature, the shorter the time required. Drilling rational design (pore distribution, pore size and pore spacing hole depth) can easily crush hard rock and reinforced concrete. Usually after 2 to 24 hours, can in no vibration, no noise, no flying rocks, no harmful gases under a state object broken or cut open. It is the ideal alternative to today's other blasting tools. Mine silent expansive use: 1, underground structures: such as subways, underground parking, underground warehouses, tunnels, mines, air defense projects, excavation, etc., mixing station etc; 2, pool, swimming pools, water towers, tanks, large containers, silos, tanks, warehouses and other cave; 3, high strength highway pavement, bridge concrete surface, culvert; 4, anchor prefabricated frame structure connection joints, pipe joints, post-tensioned precast grouting material, After pouring seam backfill grouting material lava; 5, cement products: from stress, prestressed and prestressed concrete steel jacket pipes, slabs, columns, beams, waterproof roof; 6, anchor bolts mechanical equipment, machines no contraction between the seat and the concrete foundation perfusion; more mines silent expansive visit http://www.xzbsjc.com/
