Tuairisgeul
Tha Vermiculite na mhèinnear silicate nàdarra neo-organach, air a thoirt a-mach le tomhas de uisgeachadh clach-ghràin (mar as trice air a thoirt a-mach aig an aon àm le asbestos), ann an cumadh mar mica. Is e na prìomh dhùthchannan cinneasachaidh vermiculite Sìona, an Ruis, Afraga a Deas, na Stàitean Aonaichte, msaa. Faodar Vermiculite a roinn ann an flakes vermiculite agus vermiculite leudaichte a rèir an àrd-ùrlar, agus faodar cuideachd a roinn ann an vermiculite òir, vermiculite airgid, agus geal bleogach. vermiculite a rèir an dath. Às deidh calcination àrd-teòthachd, faodaidh meud vermiculite amh leudachadh gu luath le 6 gu 20 uair.
The expanded vermiculite has a layered structure and a specific gravity of 60-180kg/m3. It has strong insulation and good electrical insulation properties, with a maximum usage temperature of 1100°C. Expanded vermiculite is widely used in industries such as insulation materials, fire-resistant materials, seedling cultivation, flower planting, tree planting, friction materials, sealing materials, electrical insulation materials, coatings, plates, paints, rubber, refractory materials, hard water softeners, smelting, construction, shipbuilding, chemistry, etc...
