99.9% Nano silica
Nano-silica muaj cov yam ntxwv ntawm cov khoom me me, cov micropores loj, thaj chaw loj, cov hydroxyl ntau ntawm qhov chaw, muaj peev xwm cuam tshuam rau lub teeb ultraviolet, lub teeb pom kev thiab lub teeb infrared. Tshwj xeeb tshaj yog nrog kev txhim kho ntawm cov txheej txheem kho qhov chaw ntawm cov khoom, qhov kev sib sau ua ke ntawm cov khoom nano yog qhov pom tseeb txo qis, thiab kev sib raug zoo nrog cov khoom siv organic polymer zoo, uas ua rau daim ntawv thov ntawm cov khoom dav dua.
