Sanding yog thawj kauj ruam hauv kev ua tiav txhua qhov haujlwm ua haujlwm ntoo. Txawm hais tias koj siv lub zog sander lossis xuab zeb los ntawm tes, koj yuav tsum xaiv hom thiab grit ntawm cov ntawv xuab zeb. Sanding nrog cov ntawv xuab zeb tsis raug tuaj yeem ua rau koj txoj haujlwm tsis raug.
Xaiv Txoj Cai Grit
Sandpaper yog ntsuas los ntawm tus naj npawb ntawm abrasive hais ib square inch. Cov grit loj hlob rougher raws li tus lej txo. Cov ntawv xuab zeb feem ntau raug faib ua ntxhib (40 txog 60 grit), nruab nrab (80 mus rau 120 grit), nplua (150 mus rau 180 grit), zoo heev (220 mus rau 240 grit), nplua ntxiv (280 mus rau 320 grit), thiab super nplua (280 rau 320 grit) (360 thiab siab dua). Sanding nrog finer grits tshem tawm cov khawb sab laug los ntawm daim ntawv ua ntej, tawm hauv qhov ua tiav."Vim li cas kuv tsis tuaj yeem xuab zeb tag nrho siv Super Fine sandpaper?" tej zaum koj yuav xav tsis thoob. Tsis muaj ib yam dab tsi uas hais tias koj ua tsis tau, tab sis cov nplooj ntawv coarse grit yuav tshem tawm cov khoom sai sai thiab, thaum ua raws li cov ntaub ntawv zoo dua, yuav ua rau cov xuab zeb yooj yim dua thiab sai dua. Raws li yuav luag txhua tus kws tshaj lij woodworker yuav qhia rau tus neeg tshiab, qhov sai dua koj tuaj yeem ua tiav sanding, qhov zoo dua.
Qib Sandpaper
Sandpaper tau muab faib ua ob hom: qib lag luam thiab qib kev lag luam. Cov kev sib txawv muaj nyob rau hauv ob peb qhov chaw, nrog rau cov khoom grit, cov ntaub ntawv thaub qab (daim ntawv), thiab cov kua nplaum siv los tuav cov grit rau ntawv. Rau tag nrho peb yam, qib kev lag luam siv cov ntaub ntawv zoo dua.Koj tuaj yeem tuaj hla cov ntawv xuab zeb sau tias "qhib-coat" lossis "kaw-coat." Qhov txawv yog tias cov grit particles nyob rau hauv kaw-coat sandpaper yog ntau ze packed ua ke, whereas open-coat sandpaper muaj ntau dua qhov sib txawv ntawm cov hais. Raws li txoj cai dav dav, qhib-coat yog qhov zoo dua rau kev ua haujlwm ntoo vim tias nws clogs tsawg dua, tshwj xeeb tshaj yog thaum ua haujlwm nrog cov ntoo mos uas muaj cov resin ntau dua.
Hom Abrasives
Muaj tsib hom ntawv xuab zeb muaj, tab sis tsis yog txhua tus ntawm lawv tsim nyog rau kev ua haujlwm ntoo. Glasspaper, qee zaum hu ua flint paper, yog ib daim ntawv hnyav, daj-daj. Glasspaper nkag tau yooj yim disintegrates thiab yog tsis tshua muaj siv nyob rau hauv woodworking.Garnet ntawv yog ib daim ntawv xim av-liab uas feem ntau siv hauv kev ua ntoo. Nws tsis xuab zeb ntoo sai npaum li lwm cov ntawv xuab zeb, tab sis nws ua rau lub ntsej muag smoother. Garnet yog ib qho zoo kawg sanding khoom.
Aluminium oxide sandpaper yog lwm qhov kev xaiv nrov rau kev ua haujlwm ntoo. Nws yog hom ntawv tshaj plaws uas siv hauv lub zog sanders. Aluminium oxide yog qhov ruaj khov dua li daim ntawv garnet, txawm hais tias nws tsis tsim tib lub polish.Silicon Carbide daim ntawv feem ntau yog tsaus grey lossis txawm tias xim dub. Daim ntawv no feem ntau yog siv rau polishing hlau los yog "ntub-xuab zeb," uas yog siv dej los ua roj nplua nyeem. Thaum daim ntawv Silicon Carbide siv rau hauv qee qhov kev ua tiav tiav, nws tsis yog feem ntau siv hauv kev ua haujlwm ntoo.
Thaum kawg, ceramic sandpaper yog tsim los ntawm ib co ntawm cov feem ntau resilient abrasives muaj thiab sai sai tshem tawm cov khoom loj. Ceramic ntawv feem ntau yog siv rau txoj siv tawv sander, tab sis nws kuj siv tau los ua ntoo los ntawm tes. Ceramic sandpaper feem ntau tawm ntawm qhov chaw ntxhib heev, yog li siv nws nrog ceev faj, tshwj xeeb tshaj yog ntawm plywood thiab veneers, qhov twg nws tuaj yeem xuab zeb sai sai los ntawm txheej txheej thiab ua kom puas.
Tau txais qhov kawg
Pib nrog ntau yam ntxhib-grit Aluminium Oxide cov ntaub ntawv rau thawj zaug sanding cov kauj ruam, ua raws li cov ntaub ntawv zoo-grit Garnet, yuav zoo li tawm ntawm qhov ua tiav zoo heev uas yuav qhia tawm koj cov txuj ci woodworking thiab muab koj lub platform zoo heev rau staining lossis pleev xim koj cov ntoo. qhov project nyob rau hauv feem ntau siv woodworking.
