P珍珠 rock is a glassy rock formed from acidic lava that has been explosively cooled during volcanic eruptions, named for its pearl-like fracture structure. The pearl rock deposits include pearl rock, obsidian, and pitchstone. The difference between them lies in the round-arc cracks formed by condensation in pearl rock, known as the pearl rock structure, with a moisture content of 2~6%; pitchstone has a unique resinous luster, with a moisture content of 6~10%; and obsidian has a glassy luster and a conchoidal fracture, with a moisture content usually less than 2%.
Expanded Perlite raw sand, after being finely and ultra-finely crushed, can be used as a filler in rubber-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, flame-retardant, and sound-absorbent. It is widely applied in various industrial sectors.
Widely applied in: concrete aggregates; lightweight, thermal insulation, heat-insulating and sound-absorbing boards; fire-resistant roof materials and fillers for high-rise building walls that are lightweight, frost-proof, shockproof, fireproof, and radiation-proof; thermal insulation for various industrial equipment and pipelines; inner walls for deep-freeze and cold storage projects; inner walls for storage and transportation of low-boiling-point liquids and gases.
