With the vigorous development of cogeneration and central heating in China, the steam pipe network for long distance transportation is gradually increasing, which is bound to place higher requirements on the adiabatic heat preservation engineering of steam pipelines. With the continuous development of the material processing industry in China, thermal insulation material has also made great progress and development. The new silica Aerogel thermal insulation material has low thermal conductivity, good thermal insulation and thermal insulation properties, stable physical and chemical properties, high temperature non-flammable, complete Waterproof, non-toxic, green and many other excellent performance in one, the current part of the high-temperature steam pipe and buried steam pipe project has been the first to use.
Aerogel is composed of 98% air and is a new type of amorphous solid material which is aggregated by nanometer particles and uses air as dispersion medium. It is a lightweight nano-porous material with unique optical, thermal and electrical properties, Nano-porous three-dimensional structure, the main component is silica, it is also known as silica Aerogel.
Due to its unique nano-porous structure, silica Aerogel can effectively prevent the heat transfer in three ways. The Aerogel covers the air and the diameter of 30-70mm can reduce the heat convection (70mm air static), nano-porous structure To bulk density, Aerogel unlimited length, can limit the heat conduction, arc structure and more, with the effect of the sun visor can be infinitely reduce heat radiation, excellent thermal insulation effect is 2 to 5 times the traditional insulation material And longer life expectancy.
