Thaum xaiv cov ntaub ntawv rau kev txiav ua, nws yog ib qho tseem ceeb kom xav txog cov khoom tshwj xeeb thiab cov yam ntxwv ntawm cov khoom, nrog rau cov kev xav tau ntawm cov khoom kawg. Nov yog qee qhov kev txiav txim siab dav dav rau kev xaiv xaiv hauv kev txiav cov khoom lag luam:

Hardness: Cov ntaub ntawv nrog cov tawv tawv siab, xws li cov hlau thiab tawv plastics, tuaj yeem xav tau cov cuab yeej txiav nrog cov txiaj ntsig zoo.

Thickness: cov tuab ntawm cov khoom siv yuav cuam tshuam cov kev xaiv ntawm kev txiav txheej txheem thiab khoom siv. Thicker cov ntaub ntawv yuav xav tau ntau cov cuab yeej lossis cov hau kev ntau.

Thaum tshav kub kub siab: Qee cov ntaub ntawv muaj kev nkag siab txog kev tsim cua sov thaum lub sijhawm txiav, yog li cov hau kev zoo li cov dej txiav dej txiav los ntawm cov thaj chaw kub.

Hom khoom: Cov hau kev sib txawv yuav yog qhov tsim nyog rau cov ntaub ntawv tshwj xeeb. Piv txwv li, kev txiav laser laser feem ntau yog siv rau cov hlau, thaum dej nres tsheb txiav yog tsim nyog rau ntau cov ntaub ntawv suav nrog cov khoom siv hlau, plastics, thiab sib sau.

Nto tas: Cov kev xav nto tiav ntawm cov khoom txiav tej zaum yuav cuam tshuam rau kev xaiv ntawm kev txiav. Piv txwv, cov kev txiav nyom abrasive yuav ua rau cov npoo ntxhib piv rau laser txiav.

Los ntawm kev xav txog cov xwm txheej no, cov tuam txhab tuaj yeem xaiv cov khoom tsim nyog tshaj plaws rau kev txiav cov khoom kom ua tiav cov txiaj ntsig xav tau.
