1, Rock wool
Rock wool is a natural and artificial inorganic fiber, and is currently one of the commonly used insulation materials. The thermal insulation performance of rock wool is very good, and it also has a certain sound insulation effect. In addition, it also has excellent chemical corrosion resistance and fire resistance, and is not easy to burn when exposed to high temperatures.
2, Aluminum silicate
Aluminum silicate is a new type of inorganic insulation material, which has good efficient insulation performance and fire resistance. Aluminum silicate also has good corrosion resistance and long service life characteristics, which have a good effect on boiler insulation. However, the price of aluminum silicate is relatively high and cost factors need to be considered.
3, Aerogel
Aerogel is a kind of material with many excellent properties, among which the most remarkable is its thermal insulation performance. The thermal conductivity of silicon aerogel is very low, even lower than 0.016 W/(m · K). Thermal insulation applied in aerospace, construction, refrigerated vehicles, space suits and other fields.
