\”Airgel\” How to Make
Light texture, simply, microlens, the color was light pink, light blue, white …… Graduate School of Materials Science and Engineering, Nanjing University, Zhu Kunmeng students placed her experimental products in the laboratory, Professor Cui L, a kind of magic materials – aerogels . Airgel is a three-dimensional network structure of the nanomaterial, having excellent properties of low density, high surface area and low thermal conductivity, can be used Building insulation and industrial insulation, is ten future development one of the new material. Properties of building insulation materials protrusion is now wall insulation to polystyrene foam-based, high thermal conductivity and high temperature difference. Airgel as a building outer insulating material , the inside of the mesoporous structure, compared to conventional such that it has more excellent heat insulating material Insulation effects, the thermal conductivity is also lower than still air, insulation performance is more prominent solid material. \”Airgel insulation materials belong to class A, to Mars will not burn, it is also effective as a thermal insulation material to reduce the possibility of fire.\” Said Cui L, \”airgel low thermal conductivity, as the wall body thinner than conventional insulation materials insulation material and good effect. \”as well as wall insulation, aerogels may also participate in the production of windows, glass reinforced insulation effect. Airgel is now applied to the granular and chunk two kinds of glass. It is understood that the intermediate particulate airgel glazing filled with airgel particles, the outer layer is a Low-E glass, translucent poor this scheme, but the heat loss is small; airgel glazing block, which is light-transmissive rate of up to 0.75, good sound insulation. At present the practical application of airgel particles to the main program, the highest saving rate up to 80%. Materials Science Dr. Rank Conventional foamed cement, foam glass and the like as a foamed ceramic substrate, vacuum impregnation, and rapid binding ethanol supercritical drying process, the preparation of a series of a foamed SiO2 airgel matrix composite insulation material. The thermal conductivity of the material as low as 0.045W / (m · K), and overcomes the deficiencies of non-compressive break strength airgel material, not weight bearing, compression off capability comprising airgel, may be used in certain structure for support material, by machining can also be adapted to different environmental requirements. \”In the summer, hot areas, the material for commercial building facades, plus alternative to traditional insulation layer structure of concrete, can be saved20% of the total annual energy consumption. \”Rank Conventional said,\” In addition to building applications, the material in cold storage insulation, furnace insulation and heat pipe insulation, and other fields have broad application prospects. \”\” New Power \”booster industrial insulation crystal growth furnace silicon photovoltaic industry is an important production equipment, high production temperature need its internal energy efficient insulation material, reduce energy consumption. ho lock member RESEARCH 1602 class students crystalline silicon photovoltaic industry growth furnace for energy saving, low preparation cost is proposed, long life cycle and low thermal conductivity of the new high-temperature carbon fiber reinforced airgel material carbide, silicon crystal growth furnace effectively replacing high-purity graphite felt, breaking the double technical and financial barriers. the project won the top award at the just-concluded sixteenth \”Challenge Cup\” contest Jiangsu game. \”traditional insulation materials mainly high thermal conductivity, corrosion Wen defects and poor. We compared the domestic and commercial products airgel, airgel products currently found on the market, while having low thermal conductivity, but low maximum operating temperature, and temperature resistance poor. \”Ho said lock,\” we inorganic aluminum salt as a raw material and a boron source, a carbon fiber as a reinforcing material, prepared in a number of key technologies to break often warmed conductivity lower than 0.05, maximum compressive strength of 9.1 MPa, good thermal stability carbon fiber reinforced airgel carbide. \”The product is now in JinkoSolar Holdings Limited and Suqian Institute pilot study of new materials, carbon fiber reinforced carbide completed airgel material acquisition pilot line, pilot production and research applications. good application prospects and economic value aerogels have broad application prospects, can be used in aerospace, petrochemical, new energy, transportation and other fields. \”if the use of such insulation materials in laptops and mobile phones, you can boot from the heat neighboring shed, help to improve the thermal efficiency, enhance the use of comfort. \”Professor Cui L, said,\” airgel can also be applied to the lithium battery of new energy vehicles, lithium battery coupled between the airgel product, can prevent heat from affecting each other each lithium battery, the battery can be further prevented due to high temperature leads to burning. \”November 19, 2017 China Association of energy-saving insulation material airgel materials branch was established, Nanjing University to become president of the unit. In recent years, Nanjing University of Technology research and development, including thermal insulation, adsorption, carrying medicine, photocatalyticAnd use of antimicrobial use and other airgel material, formed Shen Xiao-dong, Choi was promoted to leader of the research team. Currently airgel results have been transferred to many enterprises to achieve industrial applications. Wherein, based on nano airgel insulating material insulated pipe channel, holding tanks and other items have been accumulated economic 245,720,000 yuan. In the field of adsorption, polypropylene fiber composite airgel material products to effectively deal with oil pollution treatment, the cumulative economic benefits of 54.524 million yuan.
