Sanding sponge, muaj cov ntaub ntawv abrasive, tsim los ua haujlwm yuav luag txhua yam ntaub ntawv. Kev ua tiav feem ntau nkag siab tias yog kev sib tsoo thiab polishing ntawm qhov chaw. Txij li thaum qee qhov yuav tsum tau ua cov txheej txheem sib txawv, cov sponges kuj tuaj nrog cov tawv tawv sib txawv, nrog cov nplej sib txawv, thiab cov duab sib txawv.

piav qhia dav dav ntawm daim txhuam cev

Yog tias peb tham txog kev sib tsoo daim txhuam cev, tom qab ntawd ntawm tag nrho cov khoom siv abrasive hom no suav hais tias yog softest, feem ntau maj mam. Raws li cov khoom siv raw rau kev tsim cov khoom lag luam, cov ntaub ntawv mos yog siv, uas yog coated nrog abrasives. Daim ntawv thov tseem ceeb ntawm cov khoom siv no yog lub teeb sanding ntawm ntoo txheej, kua roj vanish, primer, xim. Ntawm no nws yog tsim nyog hais tias txheej abrasive tuaj yeem yog ib sab, ob sab thiab plaub sab. Silicon carbide rau daim txhuam cev feem ntau yog siv los ua abrasive.

Txoj phuam nrog ntau txheej

Pib nrog ib lub ntsej muag xuab zeb. Nws suav hais tias yog qhov yooj yim tshaj plawsdaim ntawv thov. Nws qhov txiaj ntsig tseem ceeb ntawm lwm tus yog txheej txheej me me, uas ua rau nws siv tau yooj yim dua. Qhov no yog cov cuab yeej tseem ceeb tshaj plaws nyob rau hauv cov xwm txheej uas yuav tsum tau ua cov txheej txheem nrog cov kev txiav muaj zog, pob thiab lwm yam tsis zoo.

Hom tom ntej yog daim txhuam cev txhuam nrog ob txheej txheej. Cov kws tshaj lij tau sau tseg tias nws yuav yooj yim siv hom kev sib tsoo daim txhuam cev, tsis hais qhov twg yuav tsum tau ua tiav. Nws yog qhov zoo tshaj plaws rau qhov chaw profiled hauv yuav luag txhua yam khoom siv.

hom kawg yog daim txhuam cev plaub sab. Hom abrasive no yog siv dav heev yog tias tsim nyog los ua haujlwm nrog ntoo. Sanding pads rau ntoo nrog plaub-sided abrasive yog zoo heev txawm rau nruab nrab ua hauj lwm, thaum priming los yog varnishing ib tug ntoo nto. Feem ntau, daim txhuam cev nrog qhov nruab nrab hardness twb tau siv rau kev ua haujlwm zoo li no. Nws qhov zoo dua qhov nruj dua yog qhov muaj cov yas me me, uas ua rau cov txheej txheem ua haujlwm yooj yim heev.

Siv daim txhuam cev

Hnub no, kev sib tsoo abrasive daim txhuam cev yog siv dav tshaj plaws hauv kev tsim cov rooj tog hauv txee. Yog tias tsis siv cov cuab yeej zoo li no, nws yog qhov tsis yooj yim sua kom tau txais ib qho chaw tiaj tiaj uas cov rooj tog yuav tsum muaj. Qhov no yog ib qho tseem ceeb heev, vim hais tias tam sim no cov kev xav tau rau cov tsos ntawm rooj tog yog heev siab. Kev siv daim txhuam cev sib tsoo tso cai rau koj kom tau txais tsis tau tsuas yog zoo kawg nkaus dunto, tab sis kuj txuag lub sijhawm ua haujlwm thiab txhim kho kev ua haujlwm zoo.

Lub neej ntawm daim txhuam cev thiab nws qhov yooj yim ntawm kev siv tau ua rau qhov tseeb tias lawv siv yuav luag txhua qhov chaw. Txog niaj hnub no, txhua hom kev ua tiav tsis tuaj yeem ua yam tsis muaj kev siv cov sponge lossis tsis muaj abrasive zoo sib xws thiab tsis muaj.

khoom thiab qauv

Raws li cov cuab yeej sib tsoo, lawv feem ntau muaj peb yam: abrasive, substrate thiab cov khoom sib txuas. Peb tham txog cov khoom siv abrasive, nws yog lub sijhawm los saib xyuas ob yam tseem ceeb.

Lub ntsiab lus thib ob yog qhov txhawb nqa. Nws feem ntau yog siv los ua daim ntawv lossis ntaub hauv paus, uas cov khoom siv abrasive yog glued. Cov ntaub ntawv siv tau ntau dua rau kev siv xuab zeb, yob, thiab lwm yam. Daim ntawv yog siv rau xuab zeb los yog discs. Nws tseem tsim nyog ntxiv tias lwm cov hauv paus tau pom ib ntus, piv txwv li, polyester. Lub tuam txhab ZUBR tau dhau los ua tus neeg sawv cev zoo ntawm cov khoom lag luam zoo. Sib tsoo sponges ntawm lub tuam txhab no yog cov khoom zoo. Lub hauv paus yog elastic EVA. Aluminium oxide thiab hluavtaws cob yog siv los ua ib daim ntawv khi.

Ib daim ntawv cog lus rau daim txhuam cev yog ib txheej ntawm qee cov tshuaj nplaum uas tuaj yeem tuav cov tshuaj abrasive.

Lwm qhov tseem ceeb heev yog graininess. Thaum xaiv ib daim txhuam cev, nws yog ib qho tseem ceeb heev uas yuav tsum xaiv tus yam ntxwv no kom raugyam khoom. Qhov ntsuas no yog qhov tseem ceeb tshaj plaws, tshwj xeeb tshaj yog thaum xaiv daim txhuam cev rau kev ua ntoo, piv txwv li. Lub peev xwm ntawm cov khoom kom ua tau zoo ntawm cov khoom siv yog nyob ntawm qhov graininess thiab nws gradation.
