Ci ntsa iab nthuav dav perlite yog ib hom qauv ntxeem tau, dawb, cov khoom xoob ua los ntawm acidic volcanic vitreous lava los ntawm kev sib tsoo, ua kom sov, ci thiab nthuav dav. Nws muaj lub peev xwm me, tsis muaj cua sov ua kom sov, muaj tshuaj lom neeg ruaj khov, tsis kub hnyiab, tsis kub hnyiab thiab tsis kub hnyiab. Cov tshuaj lom, tsis hnov tsw, nqus suab thiab lwm yam ntxwv.
Ci ntsa iab nthuav perlite (nthuav perlite rau ultra-qis kub thiab super-zog engineering) yog cov khoom lag luam tau los ntawm kev xaiv me me ntawm cov hmoov zoo thiab ore hauv cov ntsug ntsug kiln nrog cov nkev nkev raws li cua sov, thiab cua sov thiab nthuav dav. Cov khoom lag luam txhim kho tau txau nrog silicone rau saum npoo ntawm nthuav perlite, Ua kom muaj cov qauv hydrophobic. Cov xim, qhov ntom ntom ntom ntom ntom ntom thiab cov yam ntxwv ntawm cov khoom zoo ib yam li nthuav dav perlite. Cov khoom no feem ntau yog siv rau kev tsim cov txheej txheem loj-kub tsis tshua muaj cua sov txheej txheej txheej txheej rwb thaiv tsev, xws li cov pa tsim cov pa cua sib cais, cov nkev nkev, kua hydrogen, kua nitrogen, kua oxygen txias tub yees thauj tsheb thiab nkoj. Cov khoom no muaj qhov ua tau zoo ultra-low kub rwb thaiv tsev.
