Airgel Uses

Airgel, English aerogel, also known as dry gel. When the gel off most of the solvent, the gel content is much less than in the liquid content of the solids, or gel spatial network structure is filled with a gas medium, the look as a solid, which is the xerogel, but also called airgel. Such as gelatin, gum arabic, silica gel, hair, nails and so on. Airgel also has properties of the gel, i.e., having a swelling action, a thixotropic effect, syneresis. Airgel is a solid physical form, one of the world\’s small density of the solid. Density of 3 kilograms per cubic meter. General common silicon airgel airgel, which was first proposed by American scientists Kistler bet made in 1931 because of their friends. Many types of airgel, silicon-based, carbon-based, sulfur-based, metal oxide, metal-based and the like. aerogel is a combination of words, here aero is an adjective, represents flight, gel apparently gel. Literally can fly gel. It can be any substance as long as the gel after drying after removal of the solvent inside, but also to substantially maintain its shape unchanged, and the product having a high porosity, low density, can call all the airgel. Because very low density, only 0.16 milligrams per cubic centimeter, slightly lower than the density of air lightest aerogels, it is also called \”frozen smoke\” or \”blue smoke.\” Since the inside of the particles are very small (nanometer scale), so when it is visible through a small scattering (Rayleigh scattering), just as the sun through the air. So, it looked like the sky and the blue (if there is no doping other things), if we look to the light a little red. (The sky is blue, and the evening sky is red). Since the airgel is generally more than 80% of air, so there is very good thermal insulation effect, quite inch thick airgel 20-30 ordinary glass. 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. Also airgel particle physics experiments, using the detector as Cherenkov effect. Bit Belle experiment detector KEK B meson in the factory called airgel Cherenkov counter (Aerogel Cherenkov Counter, ACC) particle discriminator, it is a new application instance. The probeLow refraction index between the liquid and the properties of the gas detector using the airgel, as well as the nature of the solid and high transmittance, is superior to the traditional practice of using high pressure air or cryogenic liquids.

With the continuous improvement of group performance motor car, body structure and materials also will have a series of changes, and these changes will have an impact on the EMU body insulation properties. EMU roof insulation properties is one of the main factors that affect the body heat, the effects of different thermal insulation properties of the roof structure, dynamic analysis of energy consumption for EMU to determine its air conditioning load and avoid harsh working conditions (dew inner wall the local temperature is too high) appears, and the maintenance of the car comfortable thermal environment are of great significance. Electric car in winter heat in whether the normal, safe driving and the car is equipped with power battery has a great relationship. At high temperatures, if no suitable cooling solution, the temperature around the battery pack a larger difference, influence the consistency of the battery cell and trigger a series of follow-up questions. One of the more serious is that the battery charge lead to \”thermal runaway\”, and thus make electric vehicles on fire, explosion. The airgel material itself has a Class A fire function, when new energy vehicles due to \”thermal runaway\” and fire, but also can play a good role in thermal protection for passengers to escape from or to win more time to extinguish the fire, and then reduce losses. Nature and influenced by the temperature of the battery power factor, the discharge efficiency changes with temperature changes, thus affecting the performance of the electric vehicle. Winter can be a good solution to the new energy automotive battery pack temperature is too low problems. The thickness of conventional materials only 1/5 ~ 1/3You can achieve the same insulating effect for the limited space of the battery pack to save more valuable space, equivalent to the thickness of the insulation effect is more durable than traditional materials, very good problem-solving cold winter, new energy battery pack life decline, improve power utilization efficiency while also extend the life of the battery pack. In recent years, people\’s attention to environmental protection, development and utilization of natural gas more and more attention. Because of the uneven distribution of the world\’s natural gas, the maritime transportation of natural gas as possible, with the acceleration of the development of natural gas resources, China\’s liquefied natural gas has entered a new stage. Liquefied natural gas (LNG) at a temperature of about -162 deg.] C at atmospheric pressure, a large LNG storage device can not withstand high pressure, it can only be transported under normal pressure or low pressure conditions. LNG from production to use can be divided into the following five parts: the production of LNG, shipping, receiving, allocation, subscriber. Each and every element there is some delivery problems. In order to improve the effect of cold storage tank of the LNG carrier, LNG reduced evaporation rate, from a development standpoint, select the appropriate cold insulation material is necessary.
