Sandpaper, ib qho cuab yeej zoo li yooj yim, nqa ntau yam kev siv thev naus laus zis thiab kev siv. Cia peb ua tib zoo saib thiab nkag siab txog qhov sib txawv ntawm cov ntawv xuab zeb.
1. Hom
Sandpaper tuaj yeem muab faib ua ob hom: ntawv xuab zeb dej thiab cov ntawv xuab zeb qhuav raws li kev siv sib txawv.
Cov ntawv xuab zeb qhuav: Cov abrasive yog khi rau latex nrog cov khoom siv hluavtaws ua cov ntawv khi thiab coated nrog antistatic txheej. Nws muaj cov yam ntxwv ntawm kev tiv thaiv kev thaiv, tiv thaiv zoo li qub, zoo softness, siab hnav tsis kam, thiab lwm yam, thiab haum rau kev sib tsoo qhuav.
Cov ntawv xuab zeb dej (dej-resistant sandpaper): Sandpaper nrog dej-resistant ntawv los yog kho cov dej-resistant ntawv raws li lub hauv paus hu ua dej xuab zeb. Nws feem ntau yog ua los ntawm kev sib koom ua ke ntawm cov abrasive rau lub hauv paus nrog cov xim los yog resin ua ib daim ntawv khi. Nws yog siv los txhuam qhov saum npoo ntawm cov hlau lossis cov khoom tsis yog hlau hauv dej lossis roj.
2. Kev cuam tshuam ntawm lub hauv paus hnyav
Lub hauv paus hnyav ntawm cov ntawv xuab zeb, xws li AW yog 65g / cm², ncaj qha cuam tshuam rau nws txoj kev khoov, toughness thiab mechanical resistance. Sandpapers ntawm qhov hnyav sib txawv yog AW (Ib qhov hnyav), CW, DW, EW, FW, thiab lwm yam los ntawm lub teeb mus rau hnyav. AW yog lub teeb tshaj plaws thiab feem ntau yog siv rau kev siv xuab zeb; CW yog tsim rau phau ntawv sanding thiab lub teeb mechanical sanding (portable vibration sander); DW thiab saum toj no yog rau mechanical sanding; EW thiab FW yog rau cov xuab zeb hnyav. Cov kev xav tau sib txawv xav tau kev xaiv sib txawv.
3. Cov khoom siv raw
Cov ntawv xuab zeb qhuav feem ntau siv cov abrasives xws li xim av corundum, dawb corundum, thiab zirconium corundum. Qhov zoo yog kev sib tsoo siab thiab tsis yooj yim rau lo rau chips, uas yog tsim rau kev sib tsoo qhuav; Cov ntawv xuab zeb dej feem ntau siv corundum lossis silicon carbide abrasives, uas muaj qhov zoo nkauj zoo nkauj thiab tsim nyog rau kev sib tsoo qee yam nrog kev ntxhib los mos zoo thiab haum rau kev ua haujlwm tom qab.
Kev xaiv ntawm ntau hom ntawv xuab zeb ncaj qha cuam tshuam rau nws qhov kev ua tau zoo hauv ntau qhov chaw.
4, Sandpaper Grit No.
Mesh tooj yog hais txog tus naj npawb ntawm cov qhov mesh ib nti ntawm qhov ntev ntawm lub sieve mesh, tseem hu ua sieve tooj lossis mesh tooj. Yog li ntawd, qhov ntau mesh qhov (piv txwv li, qhov me me mesh loj), qhov loj mesh tus naj npawb, uas dhau los ua qhov taw qhia ntawm qhov zoo ntawm cov khoom siv abrasive thiab indirectly ntsuas qhov fineness ntawm cov xuab zeb. Piv txwv li, 100 # sandpaper yog cov ntawv xuab zeb ua los ntawm 100 grit abrasive, nrog rau qhov chaw faib ntawm 150um abrasive hais.
Lub thickness ntawm cov ntawv xuab zeb thiab hom abrasive muaj qhov cuam tshuam loj rau lub hom phiaj thiab kev ua haujlwm ntawm cov ntawv xuab zeb. Nov yog qee qhov loj me me ntawm cov ntawv xuab zeb thiab lawv cov kev siv sib xws:
40-60 mesh: Cov pob zeb ntxhib no yog tsim rau tshem tawm cov khoom loj ntawm qhov chaw ntxhib, xws li tshem tawm cov xim qub.
80-120 grit: Cov grit loj ntawm cov ntawv xuab zeb no yog tsim los tshem tawm cov teeb meem me me, xws li cov npoo ntse lossis cov fab ntawm cov ntoo lossis hlau.
150-180 grit: Daim ntawv nruab nrab grit no tuaj yeem siv los txhuam cov npoo kom du, xws li tshem cov txheej tuab ntawm cov xim lossis txheej.
220-240 grit: Daim ntawv xuab zeb no tuaj yeem siv los tshem tawm cov teeb meem me me thiab tsim kom muaj qhov sib luag.
280-320 grit: Daim ntawv xuab zeb zoo no yog tsim rau polishing thiab smoothing ntau qhov chaw ntawm ntoo, hlau, thiab yas.
360-600 grit: Cov ntawv xuab zeb zoo tshaj plaws no tuaj yeem siv los tshem tawm cov khawb me me ntawm qhov chaw, ua rau lub ntsej muag du heev, xws li cov ntawv xuab zeb siv los ua cov txheej txheem tsheb.
1000+grit: Cov ntawv xuab zeb zoo heev no tuaj yeem siv rau kev ua haujlwm zoo tshaj plaws, xws li polishing iav lo ntsiab muag, hlau thiab yas, thiab lwm yam.
