Pearlescent sand is a porous, white, granular loose material made from acidic volcanic glass lava through processes of crushing, preheating, and pyroexpansion, featuring small capacity, low thermal conductivity, good chemical stability, non-flammability, non-toxicity, odorlessness, and sound absorption. Pearlescent sand (ultra-low temperature ultra-high strength expanded perlite) is a product obtained by heating and expanding fine particles selected from ore sand in a vertical kiln using natural gas as the heat source. The reinforced product is coated with organosilicon on the surface of the expanded perlite to form a hydrophobic structure. The product's color, bulk density, and specifications are similar to those of ordinary expanded perlite. However, this product has distinct features such as lower bulk density, lower thermal conductivity, and uniformly sized particles when compared to ordinary expanded perlite. This product is mainly used for insulation layer construction in large-scale ultra-low temperature thermal engineering projects, such as oxygen production air separation units, natural gas, liquid hydrogen, liquid nitrogen, liquid oxygen refrigerated transport vehicles and ships. The product boasts excellent ultra-low temperature insulation properties and quality exceeding European ship classification society standards. Operating temperature range: -200 to 800°C.Xinyang Zhongsen Perlite Application Co., Ltd.Situated in the non-metallic mineral area of Shangtian Ti, a pearl rock mine in Asia, we produce various grades of pearlescent sand, including 50-70 mesh, 70-90 mesh, and 90-120 mesh, which meet both domestic Hangyang Group and German Linde Company technical standards. The ultra-low-temperature insulation-grade pearlescent sand we manufacture satisfies the special requirements of ultra-low-temperature equipment such as air separation units and low-temperature liquid storage tanks. Pearlescent sand boasts characteristics such as light bulk density, low thermal conductivity, low moisture content, high porosity, scientifically reasonable particle size distribution, and high mechanical strength. All performance indicators meet the strict requirements of both domestic and international air separation equipment, fully demonstrating the unique effects of pearlescent sand in energy conservation, reducing electricity consumption, and minimizing cold loss.
