Deskripsyon
Vermiculite se yon mineral natirèl inòganik silikat, ki te pwodwi pa yon sèten kantite idratasyon granit (anjeneral pwodui ansanm ak amyant), ki gen fòm tankou mika. Pwensipal peyi ki pwodui vèrmikulit yo se Lachin, Larisi, Lafrik di sid, Etazini, elatriye. Vermiculite ka divize an flak vèrmikulit ak elaji vèrmikulit dapre etap la, epi tou li ka divize an vèrmikil an lò, vèrmikil an ajan, ak blan lakte. vèrmikulit selon koulè a. Apre kalsinasyon wo-tanperati, volim vèrmikulit anvan tout koreksyon ka elaji rapidman pa 6 a 20 fwa.
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...
