Talking about the role of airgel products

\” Aerogels \” The word appeared more and more frequently in recent years, especially in the thirteenth five-year plan in pen and ink chapters emphasize the role of new materials strategy, airgel as an advanced new materials again It has become the focus of attention. Aerogels have the insulation, thermal insulation, sound insulation, noise reduction, oil and other fields very common applications, large aerospace materials, spacesuits fire insulation clothes; small mug, car noise insulation, absorption oil spill port , a very broad field of use make airgel material by the industry great concern in the market. Significance of the development of airgel what? From the national strategic level, the new material is the upgrading of traditional industries driven by revolutionary forces, is a matter of national security strategic industries. The domestic industry to develop new materials, new materials to enhance the domestic industry manufacturing standards, so as to continuously improve the advanced polymer materials and special metal functional materials self-sufficiency level. Then compare the new materials enterprises at home and abroad, the United States 3M, DuPont, Germany\’s BASF, Bayer, Mitsubishi Chemical of Japan occupied most of the international market share, many of whom are market capitalization of over 100 billion dollars giants. The other hand, domestic new materials enterprises, A-share market capitalization of leading Guoshuo not billions of dollars. Why is there such a big gap, the gap between the start time is one of the reasons, but the main reason is that in the country, the new material has not been seen as a cause of long-term sustainable development. So, how to make the new material Constant \”new\” is a question worth considering. At present, new materials enterprises want comprehensive, all-around beyond foreign giants, is not realistic in a short time. However, in key areas such as nano-materials, but there is the sudden emergence of the space and capacity. After the talk finished first and worry about the world of industry background, we officially cut to the chase. What is airgel? As nanomaterials industry star – airgel (Aerogel), why was it in the end? First, we airgel different from conventional thinking in the \”glue\”, which is a solid form of matter density 3KG / m³, because of its low density, it is also called \”frozen smoke\” or \”blue smoke\” , he won the Guinness Book of records \”the world\’s lightest solid\” title. In 1931 it was first successfully SiO2 aerogels prepared by supercritical drying method of S.Kistler. Since the airgel is generally more than 80% of air, so there is a very good insulating effect, rather airgel inch thick ordinary glass 20-30The thermal insulation. Even on the airgel between Rose and flame, the Rose will remain intact. Aerogels in space exploration is also a variety of purposes, in the Russian \”Peace\” space station and the United States \”Mars Pathfinder\” probe has used this material. Science about airgel described here, only remember them significantly different from the pore structure in the micro and millimeter porous material fine nanostructures such low thermal conductivity material, having a great specific surface area. Light scattering sound than conventional porous material is much less, of these unique properties such that the material not only causes people interested in basic research, but also bears widely used in many fields scene. Airgel products What? What is the use? Introduced in front of the various features of this airgel nano-materials, it can be made into what exactly? From an objective point of view, combined with the progress of the relevant domestic and foreign enterprises, research institutions as we comb combing story of airgel products. About airgel products, can be divided into two parts, the first part for the application of products already have attributes of commodity circulation, the second part is cutting-edge research of great scientific value. Present aerogels include airgel particles: the above-described physical properties which makes purification airgel material itself noise insulation, water, gas adsorption aspects have outstanding advantages, can replace activated carbon as a consumable. Nanoporous airgel composite insulation materials: this is just a general term, understood as something of all places need efficient thermostat can lingua franca, as this material can be solid, liquid may be. Briefly, when such a composite insulating material is an airgel composite with a secondary substrate which, so that it has a high thermal insulation material performance. Industrial construction sector applications, the glass fiber mat composite airgel processed to make the airgel mat, such that its thermal conductivity is exponentially decreased; daily art, and textile composite, such that a thermal insulation properties and the level. So in terms of airgel composite application products, Xiao Bian prefer to see it as an additive functionality. Currently, the new airgel applications mainly in the field of energy saving and environmental protection.
