( WhatsApp/WeChat: +86 18625562875 ).
Expanded perlite is a white granular material with a honeycomb structure inside which is made by preheating and instantaneous high temperature roasting. The principle is as follows: the perlite ore is crushed to form a certain size of ore. Thermal calcination, rapid heating (above 1000 °C), water vaporization in ore, expansion in softened vitreous ore containing sand, forming a porous structure, volume expansion 10-30 times of non-metallic mineral products. Perlite according to its expansion process technology And the usage is classified into three type: open cell, closed cell, and balloon.
Expanded perlite application areas:
Architecture: insulation and heat insulation of building roofs and walls; lightweight aggregates of building materials;
Industrial: Dip-pressed hydrophobic perlite insulation board, sound absorbing panel, partition wall panel, fireproof panel, etc.;
deep cold, low temperature engineering insulation, industrial equipment, pipeline insulation, etc.;
Agriculture and horticulture: soil improver, soilless culture substrate, pesticide retardation agent;
Others: filter aids, fillers, abrasive materials, slag materials for steel making processes, etc.
