Dab tsi yog cov qauv sib txawv ntawm cov khau khiab thiab sandcloth?

Ua ntej tshaj plaws, Sandpaper yog tsim los ntawm cov khoom abrasive tso rau daim ntawv pib nrog cov nplaum. Daim ntawv puag yuav yog hom sib txawv xws li kraft daim ntawv, yas daim ntawv, dej - resistant ntawv thiab lwm yam. Cov ntaub ntawv no muab cov xuab zeb hloov tau thiab qee lub zog, yog li nws tuaj yeem siv rau kev sib tsoo ntawm txhua hom duab thiab chaw. Cov khoom siv abrasive tau sib kis tau tusyees ntawm daim ntawv saum npoo los ntawm cov nplaum, ua ib txheej uas tuaj yeem txiav thiab zom.

Tab sis cov ntaub npog tsis zoo yog ua los ntawm cov khoom abrasive rau cov ntaub npuag. Cov ntaub npuag feem ntau yog ua los ntawm cov ntaub ntawv fiber ntau, xws li cov ntaub paj rwb lossis hluavtaws ntaub. Piv rau daim ntawv pib, cov ntaub npuag no yog cov nrawm dua thiab ntau ruaj khov. Lawv tuaj yeem sawv ntsug ntau sib tsoo siab thiab cov kev sib tsoo ntev dua. Cov khoom siv abrasive kuj tseem tsau rau cov ntaub npuag los ntawm cov nplaum. Tab sis vim tias cov yam ntxwv ntawm cov ntaub ntawm cov ntaub, cov ntaub qhwv roj ntsha feem ntau muaj cov hnav zoo dua thiab kua muag tiv taus.

Dhau li ntawm qhov sib txawv hauv cov khoom sib txawv, tseem muaj qhov sib txawv ntawm qhov loj me, faib khoom thiab kev npaj ntawm cov ntaub pua tsev thiab cov ntaub qhwv. Tab sis cov kev sib txawv no feem ntau yog nyob ntawm cov txheej txheem ntau lawm thiab cov kev xav tau. Piv txwv li, cov xuab zeb tej zaum yuav muaj cov abrasive zoo nkauj me me thiab ib qho ntxiv txawm faib, yog li ntawd nws yog tsim nyog rau kev sib tsoo zoo thiab cov haujlwm polishing. Thaum cov ntaub khoob yuav muaj qhov coarser abrasive particle loj thiab ib qho denser kev npaj kom muab cov kev sib tsoo siab dua thiab muaj peev xwm nrawm dua rau cov khoom.
