Hom thiab cov teebmeem ntawm cov khoom muag
Ib qho abrasive yog ib qho khoom muag abrasive uas muaj kev sib txhuam cov khoom thiab yog ib qho adjuvant rau cov txheej txheem ntawm cov xim hlau sib tsoo. Feem ntau hais lus, nws yog sib tov ua los ntawm abrasives, dispersants (tseem hu ua kev sib tsoo kua) thiab cov ntaub ntawv pabcuam, thiab nws kuj yog qee tus kheej dej num raws li hom ntawm cov cuab yeej abrasive. Kev siv txhuam hniav yog siv rau kev sib tsoo thiab polishing, thiab cov khoom tawg yog nyob hauv ib lub xeev dawb thaum siv. Vim yog qhov sib txawv ntawm qhov sib xyaw thiab qhov sib piv ntawm tus neeg saib xyuas thiab cov ntaub ntawv pabcuam, cov khoom ntiag tug muaj lub xeev ua kua, daim ntawv muab tshuaj, thiab cov zoo li.
Kev faib tawm ntawm cov khoom sib cais yuav muab faib tau rau cov khoom siv qis thiab cov tshuaj khib nyiab raws li qhov tau siv. Cov khoom siv abrasives feem ntau yog siv cov ntaub ntawv txhuam kev sib txhuam. Raws li qhov loj me ntawm cov pob zeb, lawv muab cais ua tob tob (lossis ntsuas), nruab nrab (lossis qib nrab) thiab micro (lossis teeb). Peb hom yog siv los kho cov xim tsis xws luag xws li oxidation, khawb thiab fading ntawm cov xim tsis zoo.
