Qhov cuam tshuam ntawm Grit Number ntawm Sandpaper Performance

Cov grit tooj ntawm cov ntawv xuab zeb, piv txwv li, qhov loj ntawm cov khoom abrasive, yog qhov tseem ceeb cuam tshuam rau nws qhov kev ua tau zoo. Tus lej grit ntau dua txhais tau hais tias cov khoom ua kom zoo dua qub, ua rau muaj kev sib txhuam zoo dua. Txawm li cas los xij, cov lej loj heev tuaj yeem txo cov kev sib tsoo kom zoo, yog li kev sib npaug yuav tsum raug ntaus raws li cov cai tshwj xeeb hauv kev siv tswv yim.

Grit tooj, los yog tus naj npawb ntawm meshes ib cheeb tsam, yog ib qho tseem ceeb qhia txog fineness ntawm cov xuab zeb. Piv txwv li, 100 # sandpaper txhais tau tias nws muaj 100 meshes, piv txwv li, abrasive hais nrog ib txoj kab uas hla ntawm 150µm, yog li txiav txim siab nws cov nyhuv sanding. Qhov tseeb, qhov coarseness ntawm cov ntawv xuab zeb yog ze ze rau hom abrasive siv, yog li cuam tshuam rau nws cov ntawv tshwj xeeb thiab cov nyhuv sanding. Tom ntej no, peb yuav sib tham txog qee cov ntawv xov tooj ntawm cov ntawv xuab zeb thiab lawv cov xwm txheej uas siv tau.

• 40-60 grit: Cov ntawv xuab zeb no muaj cov coarse abrasive hais thiab feem ntau yog siv los tshem tawm cov khoom loj ntawm qhov chaw ntxhib, xws li tshem tawm cov xim qub.
• 80-120 grit: Cov ntawv xuab zeb no muaj cov qib abrasive nruab nrab thiab tsim nyog rau kev tshem tawm cov kev tsis zoo me me, xws li xuab zeb cov npoo ntse lossis cov fab ntawm cov ntoo lossis hlau.
• 150-180 grit: Hom ntawv xuab zeb no yog siv los ua kom du nto, xws li tshem cov txheej tuab ntawm cov xim los yog txheej.
• 220-240 grit: Hom ntawv xuab zeb no tuaj yeem tshem tawm qhov tsis zoo ntawm qhov me me, tsim kom muaj qhov smoother.
• 280-320 grit: Cov ntawv xuab zeb zoo yog tsim rau kev xuab zeb thiab smoothing ntau yam ntoo, hlau, thiab yas.
• 360-600 grit: Cov ntawv xuab zeb zoo ntxiv yog siv los tshem tawm cov khawb me me, ua kom lub ntsej muag du, xws li sanding automotive nto.
• 1000 thiab siab dua grit: Cov ntawv xuab zeb zoo heev yog siv rau kev ua haujlwm zoo tshaj plaws sanding, xws li sanding eyeglass lo ntsiab muag, hlau, thiab yas nto.
