珍珠岩是一种酸性的玻璃质火山喷出岩。它容重轻、导热系数小、保温、绝热、耐火、防腐、无臭、无毒,原材料丰富,价格便宜,是一种具有广泛应用价值的建筑材料。膨胀珍珠岩是珍珠岩矿石经破碎、预热、焙烧,使体积急剧膨胀制得的一种白色、多孔颗粒状轻质多功能材料。这种松散颗粒可直接充填于设备夹层,起绝热作用。也可以用不同的胶结剂制成各种形状和性能的制品,用来作管道,热工设备上的保温层及
Perlite is an acidic vitreous volcanic eruption rock. It has light weight, small thermal conductivity, thermal insulation, thermal insulation, fire resistance, corrosion resistance, odorless, non-toxic, abundant raw materials, and low price. It is a building material with wide application value. Expanded perlite is a white, porous, granular, lightweight, multi-functional material obtained by crushing, preheating, and roasting perlite ore to rapidly expand the volume. This loose particles can be directly filled in the equipment sandwich and play a role in thermal insulation. Different adhesives can also be used to make various shapes and properties of products for the insulation of pipes, thermal equipment and
