Grit Size Grading: Sandpaper grit qhov ntau thiab tsawg feem ntau qhia los ntawm cov lej (piv txwv li, 60 # txog 5000 #). Cov lej me me qhia tias coarser hais, haum rau kev tshem tawm cov khoom sai; Cov lej loj dua qhia cov khoom zoo dua, siv rau polishing zoo. Piv txwv li, 60 # sandpaper yog haum rau cov hlau ntxhib, thaum 2000 # thiab grit sandpaper feem ntau yog siv rau daim iav tiav ntawm qhov muag lo ntsiab muag lossis siab - qhov tseeb.
Substrate Hom: Sandpaper substrates muaj xws li ntawv, ntaub, thiab zaj duab xis. Daim ntawv substrates yog tsawg- nqi thiab haum rau kev siv ib zaug; daim ntaub substrates yog dej heev -resistant thiab yuav siv tau nrog dej los yog roj- raws li coolants; zaj duab xis substrates (xws li polyester zaj duab xis) muab kev puas tsuaj ntau dua thiab qhov ruaj khov.
Cov txheej txheem Bonding: Abrasive particles yog tsau rau lub substrate siv resin, tsiaj kua nplaum, los yog ceramic adhesives. Resin adhesives yog haum rau qhuav sanding, thaum ceramic adhesives tuaj yeem tiv taus qhov kub thiab txias thiab haum rau siab - ceev sanding.
Puab thiab Loj: Cov ntawv xuab zeb tuaj yeem ua tiav rau hauv cov yob, cov nplooj ntawv, cov nplhaib, lossis cov duab tsis sib xws. Roll sandpaper (piv txwv li, 115mm dav) feem ntau yog siv rau hauv pneumatic sanders, thaum daim ntawv xuab zeb (xws li, 230mm x 280mm) yog tsim rau tes sanding.
