PERLITE - Nature
Open Data Verified Data
perlite is a glassy rock formed by the rapid cooling of volcanic acid lavas, with a Pearl fissure structure. Brittle, pearlescent and oil gloss. There is a special arc-shaped crack. Hardness 5.5~7. Density 2. 2~2. 4G/cm3. Expansion ratio of up to 7~30 times, refractoriness up to 1300~1380 ℃. The Pearl Rock minerals include perlite, obsidian and turite. The three types of rock have the property of expanding under the condition of instantaneous high temperature. The difference between the three types of perlite is that perlite has a circular arc crack formed by condensation, called perlite structure, and the water content is 2% ~ 6%; the turpentine rock has a unique resin luster, water content of 6%~ 10%; Obsidian has glass luster and shell-like fracture, water content is generally less than 2%.

PERLITE - Preparation Method
Open Data Verified Data
perlite according to the different degree of processing, its products can be divided into perlite ore, perlite ore, expanded perlite and surface treatment of expanded perlite four categories.
Because the purpose of the mineral processing of perlite ore is to process the selected raw ore into products that meet the industrial requirements in terms of particle size, moisture and other indicators, that is, perlite ore sand, which determines that the mineral processing process of perlite is very simple, usually crushing, grading, drying.

PERLITE - Use
Open Data Verified Data
perlite sand by fine grinding and ultra-fine grinding, can be used for rubber and plastic products, pigments, paint, ink, synthetic glass, heat insulation Bakelite and some mechanical components and equipment as a filler. Perlite has become a new light and multi-functional material by expansion. It has the characteristics of light weight, low thermal conductivity, strong sound absorption, good chemical stability, wide temperature range, small moisture absorption ability, non-toxic, tasteless, fire prevention, sound absorption and so on, as a high-performance and ultra-lightweight insulation, heat insulation, sound insulation, decoration materials, widely used in metallurgy, petroleum, chemical, electric power, construction and defense industry, can also be used for casting, soil improvement, detergent, model filler, etc.
