Whakaahuatanga
Ko te Vermiculite he kohuke silicate parakore maori, ka puta mai i te nui o te wai whakamahana kiripaka (he mea hanga i te wa kotahi me te asbestos), he rite te ahua ki te mica. Ko nga whenua whakaputa nui o te vermiculite ko Haina, Russia, Awherika ki te Tonga, te United States, me etahi atu. Ka taea te wehea te vermiculite ki nga tawerewere vermiculite me te vermiculite whanui kia rite ki te atamira, ka taea hoki te wehewehe ki te vermiculite koura, vermiculite hiriwa, me te miraka ma. vermiculite kia rite ki te tae. Whai muri i te whakamaaramatanga o te pāmahana teitei, ka tere tere te rahi o te vermiculite mata ki te 6 ki te 20 nga wa.
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...
