Raws li tus xa khoom ntawm Abrasive Cloth Roll, Kuv tau koom nrog kev lag luam abrasives rau qee lub sijhawm. Ib qho ntawm cov lus nug uas nquag nug kuv ntsib los ntawm cov neeg siv khoom yog hais txog kev sib raug zoo ntawm cov nplej abrasive loj thiab cov xuab zeb ceev. Hauv tsab ntawv blog no, kuv yuav qhia kuv qhov kev nkag siab ntawm lub ncauj lus no raws li kev paub txog kev paub thiab kev ua haujlwm.
Nkag siab txog Abrasive Grain Size
Abrasive grain loj yog ib qho tseem ceeb hauv kev txiav txim siab kev ua tau zoo ntawm cov khoom abrasive. Nws yog feem ntau ntsuas nyob rau hauv cov nqe lus ntawm grit loj. Tus lej grit qis dua qhia tias cov nplej coarser, thaum tus lej siab dua piv rau cov nplej zoo dua. Piv txwv li, ib qho 40 - grit abrasive muaj cov nplej loj thiab coarser piv rau 220 - grit abrasive.
Coarse - grained abrasives yog tsim los tshem tawm cov khoom sai. Lawv feem ntau yog siv rau hnyav - daim ntawv thov lub luag hauj lwm xws li ntxhib shaping, tshem tawm cov khoom loj, los yog npaj qhov chaw rau kev ua tiav ntxiv. Cov nplej loj tuaj yeem txiav los ntawm cov khoom hnyav dua, tshem tawm cov khoom tseem ceeb nrog txhua qhov dhau los.
Ntawm qhov tod tes, nplua - grained abrasives yog siv rau kev ua tiav. Lawv tsim ib tug smoother nto tiav los ntawm tshem tawm me me ntawm cov khoom. Fine - grained abrasives yog qhov zoo tagnrho rau kev ua haujlwm xws li polishing, deburring, thiab ua tiav qhov siab - zoo li saum npoo.
Qhov cuam tshuam ntawm Abrasive Grain Loj ntawm Sanding Ceev
Kev sib raug zoo ntawm cov nplej loj thiab cov xuab zeb nrawm yog qhov nyuaj thiab cuam tshuam los ntawm ntau yam.
Coarse Grains thiab High Sanding Ceev
Thaum siv coarse - grained abrasives, lub sanding ceev yuav kuj siab. Cov nplej loj muaj peev xwm txiav ntau dua, uas tso cai rau lawv tshem tawm cov khoom sai. Piv txwv li, hauv kev ua hlau, 40 - grit abrasive daim ntaub yob tuaj yeem tshem tawm xeb, nplai, lossis cov hlaws loj. Cov nplej loj khawb rau hauv cov khoom, tawg nws thiab nqa nws mus. Qhov no ua rau muaj kev tshem tawm cov khoom siv siab, uas yog sib npaug rau cov xuab zeb siab ceev.
Txawm li cas los xij, muaj kev txwv rau kev siv coarse nplej ntawm kev kub ceev. Cov nplej loj tuaj yeem ua rau lub ntsej muag rougher tiav, thiab yog tias qhov nrawm dhau lawm, nws yuav ua rau muaj cua sov ntau dhau. Qhov cua sov no tuaj yeem ua rau cov khoom ua haujlwm puas tsuaj, tshwj xeeb tshaj yog tias nws yog cua sov - cov khoom rhiab zoo li cov yas lossis cov hlau mos.
Fine Grains thiab Low Sanding Speed
Fine - grained abrasives xav tau ib tug qis sanding ceev. Txij li cov nplej me me, lawv tshem tawm cov khoom hauv qhov me me. Yog tias cov xuab zeb ceev dhau lawm, cov nplej zoo yuav tsis muaj sijhawm txaus los txiav cov khoom zoo, thiab lawv yuav ua rau txhaws yooj yim dua. Clogging tshwm sim thaum cov khoom tshem tawm puv qhov chaw ntawm cov nplej, txo cov kev ua haujlwm ntawm cov abrasive.
Piv txwv li, thaum sanding ib tug ntoo nto kom tiav ib tug du tiav, ib tug 220 - grit los yog siab dua abrasive yob yuav tsum tau siv ntawm ib tug kuj qeeb ceev. Qhov no tso cai rau cov nplej nplua nuj maj mam abraded saum npoo, tsim kom du thiab txawm tiav.
Lwm yam cuam tshuam rau kev sib raug zoo
Khoom siv ua haujlwm
Hom khoom siv sanded kuj ua lub luag haujlwm tseem ceeb hauv kev sib raug zoo ntawm cov nplej loj thiab xuab zeb ceev. Cov ntaub ntawv nyuaj xws li cov hlau tsis muaj steel lossis titanium yuav tsum muaj kev sib txawv piv rau cov ntaub ntawv softer xws li ntoo lossis txhuas.
Rau cov ntaub ntawv nyuaj, coarser nplej yuav xav tau kom ua tiav qhov kev pom zoo sanding ceev. Txawm li cas los xij, cov xuab zeb ceev tseem yuav tsum tau hloov kho kom tsis txhob hnav ntau dhau ntawm cov abrasive thiab kev puas tsuaj rau lub workpiece. Nyob rau hauv sib piv, cov ntaub ntawv softer feem ntau yuav sanded nrog finer nplej ntawm ib tug kuj ceev dua yam tsis muaj kev puas tsuaj.
Abrasive Bond
Daim ntawv cog lus uas tuav cov nplej abrasive rau cov khoom siv rov qab ntawm daim ntaub abrasive yob yog lwm qhov tseem ceeb. Cov ntawv sib txawv muaj ntau theem ntawm hardness thiab yooj. Daim ntawv cog lus nyuaj tuaj yeem tuav cov nplej kom ruaj khov, tso cai rau cov xuab zeb ntau dua, tshwj xeeb tshaj yog nrog cov ntxhib - grained abrasives. Ib daim ntawv cog lus mos, ntawm qhov tod tes, yog qhov tsim nyog rau kev nplua - grained abrasives thiab tej zaum yuav xav tau cov xuab zeb qis dua los tiv thaiv cov nplej los ntawm kev rub tawm ntxov.
Kev siv tswv yim hauv Abrasive Cloth Roll Industry
Hauv peb lub lag luam raws li Abrasive Cloth Roll tsum, peb feem ntau muab kev taw qhia rau cov neeg siv khoom ntawm kev xaiv cov nplej loj thiab xuab zeb ceev rau lawv cov ntawv thov tshwj xeeb.
Rau cov neeg siv khoom hauv kev lag luam hlau fabrication, uas koom nrog cov haujlwm xws li kev sib tsoo thiab deburring, peb pom zoo kom siv coarser - grained abrasive daim ntaub yob zoo li 60 - 80 grit rau thawj txheej txheem roughing. Cov no tuaj yeem siv rau ntawm qhov nrawm nrawm ntawm txoj siv tawv sander lossis disc sander kom tshem tawm cov khoom ntau dhau. Rau kev ua tiav tiav, peb xav kom zoo dua - grained abrasives zoo li 180 - 220 grit, uas yuav tsum tau siv ntawm qhov qis dua kom ua tiav qhov chaw du.
Hauv kev lag luam woodworking, ntxhib - grained abrasives yog siv rau shaping thiab leveling ntoo, thaum zoo - grained abrasives yog siv rau sanding thiab polishing. Piv txwv li, ib qho 100 - grit abrasive daim ntaub yob tuaj yeem siv tau sai sai tshem tawm cov cim, thiab tom qab ntawd ib qho 240 - grit lossis siab dua yob tuaj yeem siv rau qhov kawg ua tiav.
Yam khoom thiab lawv lub luag haujlwm
Ntxiv rau Abrasive Cloth Rolls, muaj lwm yam khoom lag luam hauv kev lag luam abrasives uas cuam tshuam nrog cov txheej txheem sanding. Piv txwv li, Hlau Nplhaib yog ib qho tseem ceeb nyob rau hauv nrov plig plawg discs. Nws muab kev txhawb nqa thiab kev ruaj ntseg rau cov flaps abrasive, kom ntseeg tau tias lawv tuaj yeem ua haujlwm tau zoo ntawm qhov sib txawv sanding speeds.
Flap Disc Backing Phaj - fiberglass thiab Fiberglass Phaj rau Flap Disc kuj tseem ceeb heev. Cov ntawv thaub qab no muab lub hauv paus ruaj khov rau cov flaps abrasive, thiab lawv qhov zoo tuaj yeem cuam tshuam qhov kev ua tau zoo ntawm cov flap disc, nrog rau cov xuab zeb ceev thiab qhov chaw tiav.
Xaus
Hauv kev xaus, kev sib raug zoo ntawm abrasive grain loj thiab sanding ceev yog ib tug ilv tshuav nyiaj li cas nyob ntawm ntau yam. Coarse - grained abrasives feem ntau cuam tshuam nrog kev sib tsoo ntau dua rau kev tshem tawm cov khoom sai, thaum zoo - grained abrasives yuav tsum tau qis dua rau kev ua tiav. Hom ntawm cov khoom siv ua haujlwm, daim ntawv cog lus abrasive, thiab lwm yam khoom muaj feem xyuam rau txhua tus ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov zoo tshaj plaws sanding ceev rau ib qho loj npaum li cas.
Yog tias koj nyob hauv kev ua lag luam rau Abrasive Cloth Rolls lossis muaj lus nug txog qhov loj npaum li cas thiab xuab zeb ceev rau koj daim ntawv thov tshwj xeeb, kuv xav kom koj hu rau peb kom muaj kev sib tham ntxaws. Peb tau cog lus tias yuav muab siab - cov khoom zoo thiab cov lus qhia tshaj lij kom tau raws li koj cov kev xav tau abrasives.
