Detailed Description
Expanded perlite is preheated, baked instantaneous expansion by expaned perlite ore, which is made after an internal honeycomb structure of the white granular material.
Perlite Principle and the expansion of configuration:
Expanded perlite is crushed by the ore, dealed with the rapid heating (1000℃ above). After the moisture vaporization ores and minerals in the particles soften internal expansion, the formation of porous structure, expansion to the original 10-30 times. The expanded perlite can be sorted to 3 fonfiguarations by the technical conditions. They are the open hole (OPEN CELL), the obturator (CLOSED Cell), the hollow hole (BALLOON).
The expanded perlite main characteristics :
Light porous Unburning insulation
Acoustic waterproof corrosion resistance
The use field:
• Construction: lightweight aggregate, lightweight thermal insulation material, anti-fire wood, insulation mortar, etc.
• Industry: deep cold, low-temperature thermal insulation engineering, industrial equipment, piping insulation
• Agriculture: horticulture and other aspects of soil amendments, soil matrix, pesticides, etc. evanescent ease
• Other: filter aid, filler, abrasive materials
