The difference of perlite, glass beads and obturator perlite

The difference between the 1, the concept of simple terms to explain according to generalized degree: Perlite > > perlite glassy beads, in theory, all the perlite ore through high temperature expansion called expanded perlite. In the expanded perlite, spherical surface sealing, also called hollow obturator perlite; obturator perlite, expanded perlite particle size in 30-50 mesh is called glass beads, the above is the definition of science, but its real connotation has narrowed, we usually say the expansion perlite is perforated the obturator perlite and glass beads is one thing that is closed.

The difference of perlite, glass beads and obturator perlite

The difference between the 2, processing technology: glass beads and perlite is furnace production, manufacturers report is more than 90%, bibulous rate is below 20%, the heating temperature is about 1000 degrees. The daily output of 30-40 tons, glass beads products from sliding down the stratified heating, precise control of the temperature of each layer, the surface of vitrified. Expanded perlite is the furnace produced gas, heating temperature of 900 degrees, the daily output of 60-90 tons. Expanded perlite product when buoyancy over its gravity, the ore particles expansion began to flow increased with the hot gas, and continue heating and expansion. Perlite particles with hot wind kiln top to after guided steering into water level separator and cyclone fan, complete separation products.

The difference between the 3, product application: essentially expansion to low thermal conductivity than perlite vitrified micro bead and obturator perlite, expanded perlite insulation effect is better, why is cheaper? This is because the water absorption problem, expanded perlite due to higher water absorption, water absorption after high thermal conductivity. So to use the expanded perlite insulation must be modified and commonly used silicone modified solution made of hydrophobic expanded perlite, the water absorption rate of solve the problem, I think it expanded perlite insulation effect is better.

4, the different valuation method: perlite glassy beads and sold by the ton, according to the expanded perlite bag.
