产品简介 Introduction

气凝胶是由胶体粒子相互聚结构成纳米多孔网络结构，并在孔隙中充满气态分散介质的一种高分散固态材料。具有低导热系数、低密度、低介电常数、低声阻抗、高孔隙率、高比表面积等特点，在热学、电学、声学、力学、光学等领域显示优异的性能，在航天、航空、集中供热供冷、石油、天然气、建筑、交通、冶金、电子、环保等领域有着广泛巨大的应有前景。

Silica Aerogel is a kind of highly dispersed solid material, in which colloidal particles coalesce into a nanoporous network full of gaseous dispersion medium in the pores. It has such characteristics as low thermal conductivity, low density, low dielectric constant, low acoustic impedance, high porosity, high specific surface area, showing excellent performance in the fields of thermal, electrical, acoustic, mechanical, optical, etc. Furthermore, it has broad application prospects in aerospace, aviation, central heating and cooling, oil, natural gas, construction, transportation, metallurgy, electronics, environmental protection and other fields.

SiQ₂气凝胶是迄今为止已实现商业化生产的保温性能最好的材料。SiQ₂气凝胶材料具有低密度、低导热系数的特性，能有效抑制热传导；其平均孔径尺寸50nm，低于空气分子的平均自由程，能有效抑制空气热对流传热；此外SiQ₂气凝胶“无穷多”的空隙壁相当于辐射的反射面和折射面，再配合特殊的反射物质可以使热辐射降至最低。综上所述，SiQ₂气凝胶材料能有效抑制热传导、热对流和热辐射这三个方面的共同作用，几乎阻断了热传递的所有途径，是一种具有巨大应用价值的隔热材料。

SiQ2 aerogel is the best insulation material that has been produced commercially so far. SiQ2 aerogel material has the characteristics of low density and low thermal conductivity, which can effectively inhibit heat conduction. Its average pore size is 50nm, lower than the mean free path of air molecules, which can effectively inhibit air heat convection. In addition, the infinite void walls of SiQ2 aerogel act as the reflective and refractive surfaces of the radiation, and can minimize the thermal radiation coupled with special reflective material. In summary, SiQ2 aerogel material can effectively inhibit the combined effects of heat conduction, heat convection and heat radiation, almost blocking all the ways of heat transfer, so it is a kind of insulation material with great application value.
