is the nano-silica Aerogels as the main material, made of composite glass fiber through a special process with the pre-oxidized cotton fiber mat or a flexible insulation blankets. Which is characterized by low thermal conductivity, tensile and compressive strength of a certain, easy insulation construction applications, is a new type of insulating material . Airgel currently felt is from about 400 deg.] C within a temperature range of the lowest thermal conductivity of a solid insulating material (thermal conductivity of 400-1000 ℃ high temperature region is significantly higher than the thermal micro-nano series). airgel mat airgel mat having a soft ﹑ cutting ﹑ density Yi, ﹑ overall hydrophobic inorganic fire, environmental protection and other characteristics which can replace glass fiber products, asbestos insulation blankets, silicate fibers and the like are not environmentally friendly products, , poor thermal insulation performance of conventional flexible insulation material. Airgel mat mainly for industrial pipelines ﹑ storage tanks, industrial furnace, power plants, saving space, ships bulkheads, EMU, buried pipes, injection molding machines, removable insulation jacket, heavy oil recovery temperature steam pipes, transportation field, household appliances, steel, nonferrous metals, glass, etc. insulation . 1 airgel mat advantages, excellent insulation effect. Airgel insulation effect of conventional heat insulating material mat is 2-5 times, according to the experimental determination of the theoretical useful life of 20 years Arrhenius. Almost the same life of the building. 2, to reduce the thickness of insulation layer. Airgel insulation mat to obtain the same effect, the thickness of only a fraction of one of the traditional materials. After incubation heat loss is small, a high space utilization. And at high temperatures, above the performance advantage is more obvious. 3, water repellency and fire resistance. Absolute hydrophobic airgel mat, which can effectively prevent moisture from entering the pipe, the interior equipment. While having a construction fire performance class A1, aerogels and unique three-dimensional network structure to avoid the effect of thermal insulation material other long-term high-temperature sintering deformation in use, decreased sedimentation phenomena. 4, to facilitate construction. Airgel mat lightweight, easily cut, sewn to suit a variety of pipes, equipment insulation of different shapes, and less time and labor required for installation. 5, save transportation costs. Smaller package size and lighter weight can greatly reduce transportation costs of the insulation material.
