Micro silica fume used in thermal insulation materials

Micro silica fume used in thermal insulation materials

Blogs
Thermal insulation materials are usually light, loose, porous and low thermal conductivity materials. The thermal conductivity of commonly used thermal insulation materials is less than 623K (350 ℃), and the thermal conductivity should be less than 0.14W / (M. K). Thermal insulation material can slow down heat flow rate produced…
