Vitrified Microbead Electrical Furnace is also named Closed Hole Perlite Expansion Furnace, it is specially used to manufacture closed pearlite, hollow pearlite vitrification microsphere, vitrified microsphere, glassy microsphere, closed surface perlite.

What is the vitrified microbead (closed hole perlite) ?

The vitrified microbead is produced by electric furnace, also known as closed surface perlite (glassy microsphere), is the preciously control of the temperature and the time of the raw material in the expansion furnace. The product surface is melted, the air hole is closed, the spherical body is fine particles, the internal porous cavity structure, the surface is closed, the gloss is smooth, the physical and chemical properties are stable, and the quality is high.

Vitrified microbead application areas

• (1) Architecture: insulation and heat insulation of building roofs and walls; lightweight aggregates of building materials. (2) Industrial: Dip-pressed hydrophobic perlite insulation board, sound absorbing panel, partition wall panel, fireproof panel, etc. (3) Deep cold, low temperature engineering insulation, industrial equipment, pipeline insulation, etc. (4) Others: filter aids, fillers, abrasive materials, slag materials for steel making processes, etc.
