The product introduces the perlite is one kind of volcanic eruption's acidic lava, after cools the vitreous humor rock which suddenly becomes, because it has the pearl crevasse structure to acquire fame. The pearl ore includes the pearlite, shines black the crag and the pitchstone. , because three differences lie in the pearlite to have the round arc crack which the condensation forms, calls the pearlite structure, the water content 2~6%; The pitchstone has the unique resinous luster, the water content 6~10%; The black sunlight crag has the glassy luster and the conchoidal fracture, the water content is smaller than 2% generally.
main application pearl rock floor granulated substance after thin smashing and ultrafine grinding, may use in the oak modelling in the product, the pigment, the paint, the printing ink, the synthesis glass, the heat insulation bakelite and some mechanical components and the equipment makes the stopping.
the perlite becomes one kind of light quality, the multi-purpose new materials after the inflation. Has the apparent density to be light, the thermal conductivity is low, the chemical stability is good, the application temperature scope is broad, the wettability power is small, and non-toxic, tasteless, characteristics and so on fire protection, sound absorption, widely applies in many kinds of Industry sectors.
