White lava pumice stone

White lava pumice stone
Light weight, high strength, acid and alkali resistance, corrosion resistance, no pollution, no radioactive
Is a porous, lightweight glassy acidic volcano extrusive rocks, its content is equal to the rhyolite. The pumice is due to molten lava and volcano eruption condensation with the porosity of the glassy lava, the pore volume accounted for more than 50% of the volume of rock. Pumice surface roughness, particle density is 450kg/m3, loose bulk density is about 250kg/m3, Natural pumice porosity of 7l.8 - 81%, water absorption rate of 50-60%. For porous, light quality, density less than 1 g / cubic centimeters, can float on water
Pumice can not only widely used in architecture, landscape, textile industry, clothing factory, clothing and jeans washing plant, washing plant, dyeing plant and other industries,but alsoforskin care, foot care Jiapin, can remove the horny layer of the skin on the residual effective
