Pearl sand

Uses: mechanical equipment in low temperature environment, low temperature medium transmission pipeline, low temperature medium storage container and other thermal insulation layer, perlite hand washing powder.
Specifications: 50-70 mesh, 70-90 mesh, 90-120 mesh

Pearlescent sand is a porous, white, granular loose material made of acid volcanic vitreous lava by crushing, preheating, roasting and expanding. It has small capacity, low thermal conductivity, good chemical stability, non-combustible, no Poisonous, odorless, sound absorbing and other characteristics.



Pearlescent sand (expanded perlite for ultra-low temperature super-power engineering) is a product obtained by powder selection of small particles by ore in a vertical shaft kiln using natural gas as a heat source and heating and expanding. The reinforced product is sprayed with silicone on the surface of expanded perlite. Form a hydrophobic structure. The product color, bulk density and specifications are similar to ordinary expanded perlite.

Widely used in air separation equipment, storage tanks, petroleum, detergent removal lotion (hand washing powder), chemical, shipbuilding, explosive manufacturing and other fields.

This product is mainly used for the construction of large-scale ultra-low temperature thermal engineering insulation layer, such as oxygen-making air separation unit, natural gas, liquid hydrogen, liquid nitrogen, liquid oxygen refrigeration transport vehicle and so on.

This product has good ultra-low temperature insulation performance, and the product quality is better than the European classification society standard.
