Nrog rau kev tsim kho kev lag luam, kev pov tseg cov roj pov tseg insulating tau dhau los ua qhov teeb meem tseem ceeb ntawm ib puag ncig. Cov roj khib nyiab pov tseg muaj ntau yam teeb meem, thiab kev tso tawm ncaj qha tuaj yeem ua rau av thiab dej muaj kuab paug.
Txawm li cas los xij, kev rov ua dua ntawm cov roj pov tseg insulating muaj peev xwm tseem ceeb. Los ntawm cov txheej txheem ntawm lub cev thiab tshuaj lom neeg, xws li lub tshuab nqus tsev distillation thiab adsorption purification, impurities tuaj yeem raug tshem tawm tau zoo, ua tiav cov roj rov ua dua tshiab thiab ua tiav ob lub hom phiaj ntawm kev tiv thaiv ib puag ncig thiab kev siv rov qab.
Txhawb nqa cov khoom siv rov ua dua tshiab ntawm cov khib nyiab insulating roj tsis tsuas yog txo cov kev pheej hmoo ntawm ib puag ncig tab sis kuj txuag lub zog thiab cov khoom siv raw, pab txhawb kev txhim kho kom ruaj khov.
