Nano txheej yog txawv ntawm lub tswvyim ntawm waxing thiab yaj, nws yog qhov tsim ntawm qhov tseeb ntawm cov xim muaj xim Muaj peev xwm tiv thaiv ntev ntawm lub tsheb xim kom tiv thaiv kev puas tsuaj rau ib puag ncig los ntawm lub tsheb xim.
Cov khoom siv rau cov txheej txheem ceramic yog silica, los yog quartz. Cov txheej txheem tiv thaiv kab mob KISHO yog polysiloxane, uas yog ib qho polymer ntawm silicon dioxide, Nyob hauv cov xim pleev xim rau ib txheej sib cais, cais txheej nrog ib qho nyuaj, ua rau ultraviolet teeb, roj, kua qaub, alkali, hydrophobic, oleophobic muaj nuj nqi, uas tiv thaiv cov xim.
