The expanded perlite is the perlite ore preheating and instantaneous high temperature baking expansion is made of an internal honeycomb structure of white granular materials. The principle is: Perlite ore by crushing formed a certain size of ore, the preheating and baking, rapid heating (above 1000 DEG C) and sand moisture vaporizing and in softening containing glassy sand internal expansion, the formation of porous structure.
Perlite expansion and become a light, multi-functional new materials, the particle interior is honeycomb structure, non-toxic, tasteless, no rot, non flammable, acid and alkali resistance. Perlite expansion and become a light, multi-functional new materials, the particle interior is honeycomb structure, non-toxic, tasteless, no rot, non flammable, acid and alkali resistance. With different binders it can be made of the performance of different products, with the apparent low density, low thermal conductivity, good chemical stability, temperature range, low moisture absorption ability, and non-toxic, tasteless, fire prevention, sound absorption and so on characteristics, widely used in various industrial sectors.
