Pumice is an acidic lava formed from volcanic eruptions, which, upon rapid cooling, becomes a glassy rock known for its pearl-like fissured structure. Pumice deposits include pumice, obsidian, and pitchstone. The difference lies in their crystalline structures: pumice has round-arched cracks formed by condensation, known as the pumice structure, with a moisture content of 2-6%; pitchstone has a distinct resinous luster, with a moisture content of 6-10%; and obsidian features glassy luster and a shell-like fracture, with a moisture content generally less than 2%.
Expanded Perlite raw sand, after being finely and ultra-finely ground, can be used as a filler in rubber and plastic products, pigments, paints, inks, synthetic glass, thermal insulation materials, and various mechanical components and equipment. It becomes a lightweight, multi-functional new material through expansion. It features low apparent density, low thermal conductivity, good chemical stability, a wide temperature range of use, low moisture absorption, and is non-toxic, odorless, fire-resistant, and sound-absorbent. It is widely used in various industrial sectors.
Widely used in: concrete aggregates; lightweight, thermal insulation, and sound-absorbing boards; fire-resistant roof materials and fillers, mortars, and other construction materials for high-rise building walls that are fireproof, frost-proof, earthquake-proof, and radiation-proof; insulation layers for various industrial equipment and pipelines; inner walls of deep-freeze and cold storage projects; inner walls for storing low-boiling-point liquids and gases, as well as inner walls of transportation vehicles.
