Thermal insulation material

2019-06-11

Thermal insulation materials are generally lightweight, loose, porous, and fibrous materials. According to its composition, it can be divided into organic materials and inorganic materials. The former has better thermal insulation properties than the latter, but the latter is more durable than the former. The thermal conductivity is the main indicator for measuring the performance of thermal insulation materials. The smaller the thermal conductivity, the smaller the heat transferred through the material, the better the thermal insulation performance. The thermal conductivity of the material depends on the composition, internal structure, bulk density, etc., and also determines the average temperature during heat transfer and the water content of the material. rate. Generally speaking, the lighter the bulk density, the smaller the thermal conductivity.
