1, is a kind of glass as the main raw material, mixed with the right amount of blowing agent, after roasting and cooling processing annealing temperature tunnel kiln prepared by heating with a new inorganic equally closed pore structure of the insulating material. It fully preserves the chemical stability of inorganic glass, with a low bulk density, thermal conductivity, non-breathable, non-absorbent, no burning, no mildew, not rat gnawing, high mechanical strength but easy processing characteristics, the ability in addition to All except hydrogen fluoride chemical attack, known as the green-insulation. 2, there are the following six characteristics: (1) A Class non-combustible Class A non-combustible, superior fire performance; (2) the life of the building with a glass of mineral raw materials, durability, corrosion resistant, good chemical stability , does not soften, stainless borers, aging, can with life and architecture. 3, the product uses (3) size foam molding temperature stability, dimensional stability, low coefficient of linear expansion (4) Good insulation performance for lasting stability matrix glass, so minimal water absorption (volume of water absorption <0.5%). Closed internally bubbles, there is no capillary phenomenon, substantially non-hygroscopic (moisture permeability coefficient is close to zero), with good heat-insulating moisture-permeable. (5) the intensity of high apparent density 160 ~ 180kg / m3, compressive and flexural strength index of 0.4 ~ 0.6MPa, the thermal conductivity of 0.052W / (mK) around the insulation material, the highest intensity. High mechanical strength, proportional to the intensity and apparent density. (6) can be used in a wide temperature range -196 ℃ ~ + 400 ℃ temperature afraid, not afraid of cold. Exterior insulation (1) of the building, interior wall insulation and roof insulation; (2) theater, auditorium, subway and other indoor decorative sound absorption; (3) Tunnel Engineering waterproof moisture barrier; (4) compressor room, fans housing and other pumping station sound absorption; adiabatic (5) petrochemical cryogenic equipment, containers and pipes cold; (6) chimney liner.
