Raws li cov khoom siv zoo rau cov khoom kho kom zoo nkauj, chav ua noj ua kom zoo nkauj ntawm cov tub ntxhais ua noj muaj zog, kev ua kom zoo nkauj ntawm chav ua noj muaj ntau yam kev ua tau zoo thiab kev ua haujlwm ntawm kev ua tau zoo ntawm kev pom ntawm kev sib xyaw .
Chav ua noj ib txwm siv cov av nplaum uas yog cov khoom siv tuab los ntawm kev sib xyaw ua ke thiab hnav kom tsis txhob muaj zog thiab hnav tsis zoo Hom ntsiab lus tseem ceeb tseem yog cov tseem ceeb ntawm cov vuas feem ntau .
Txhawm rau txhim kho cov haujlwm, cov chav ua noj niaj hnub ua qhia cov kev sib tw tshwj xeeb ua rau cov kev sib txhuam los ntawm kev sib txhuam los ntawm kev siv corundum lossis ua yeeb yam concave-convave kev ntxhib los mos; kev tawm tsam cov cib siv nano-nplai silica txheej los txhawm rau kom cov khoom nkag mus, tshwj xeeb} Cov khoom siv hnyav tau siv .
Kev tiv thaiv ib puag ncig kev tsav cov khoom siv tshiab (xws li ya cov khoom siv nkauj ntsuab (VOC
Los ntawm kev pom kev ua lag luam, muaj cov kev sib txawv ncaj qha rau cov khoom xyaw ua ke, xws li cov khoom siv sib xyaw ua ke nrog kev siv cov khoom sib xyaw ua ke nrog kev siv cov khoom siv tau yooj yim thiab cov khoom siv hluav taws xob nrog kev siv hluav taws xob raws li kev siv tshuaj thiab cov dej noo thiab cov av noo.
Nyob rau hauv lub neej yav tom ntej, nrog kev nce qib ntawm cov khoom muaj zog, cov nplais pob zeb yog qhov ua kom muaj kev kho kom zoo dua qub thiab kev ruaj khov kho mob .
