Qhov kev faib ua feem ntawm cov abrasives ua rau ntau yam ntawm polishing thiab kev sib tsoo cov txheej txheem, suav nrog cov nyiaj ntawm kev tshem tawm thiab cov nyhuv polishing. Ntawm no yog cov kev cuam tshuam tshwj xeeb ntawm cov kev sib txheeb ntawm cov lus piv txwv ntawm cov xwm txheej:
Cov Khoom Siv Tshem Tawm:
Cov noob nplej loj ntawm cov abrasive (coarseness) ncaj qha cuam tshuam cov nyiaj ntawm kev tshem tawm. Cov abarseasives (loj loj loj) tuaj yeem tshem cov khoom, ua rau lawv haum rau cov theem sib tsoo; Kev ua kom zoo (cov nplej me me) cov khoom me me ntxiv tab sis muab ntau txoj kev ua kom zoo dua tab sis ua rau lawv haum rau kev sib tsoo thiab sib nraus kom nruj.
Polishing nyhuv:
Cov nyhuv polishing muaj feem xyuam rau cov mov loj thiab qhov nyuaj ntawm cov abrasives. Softer abrasives (xws li txhuas oxide) yog tsim nyog rau cov ntaub ntawv muag muag, thaum nyuaj abrasives (xws li pob zeb diamond) yog qhov haum rau cov khoom siv nyuaj.
Qhov tsim nyog cov abrasive tuaj yeem muab cov khoom siv sib txuas polishing, txo cov kab txaij thiab hnav tsis ncaj.
Sib tsoo twj lub neej:
Lub hardness ntawm abrasives thiab lub zog ntawm binder cuam tshuam rau lub neej ntawm cov cuab yeej sib tsoo. Cov Abrasives nyuaj thiab muaj zog binders tuaj yeem txhim kho cov hnav tsis kam ntawm cov cuab yeej sib tsoo, txuas ntxiv nws lub neej pabcuam.
Daj Roughness:
Tus finer cov abrasive grain loj dua, qis dua qhov saum npoo roughness tom qab polishing, ua rau muaj qhov chaw smoother. Txawm li cas los xij, yog tias cov nyom abrasive loj heev, nws yuav txo tau kev sib tsoo ua kom haum.
Sib tsoo kub:
Qhov sib piv ntawm cov abralisives tseem cuam tshuam rau cov cua kub tsim kho thaum lub sijhawm sib tsoo. Kev sib tsoo siab siab siab thiab cov abrasive siab yuav nce kev sib tsoo kub, uas yuav tsum tau tswj hwm los ntawm kev ntsuas txias kom txias.
Yog li no, kom ua kom zoo polishing thiab sib tsoo txheej txheem, nws yog ib qho tsim nyog los ua tib zoo xaiv thiab kho qhov sib piv ntawm cov khoom siv abrasives raws li cov kev cai thov. Qhov no feem ntau cuam tshuam txog kev sim thiab kev ua kom zoo dua los nrhiav cov khoom muaj abrasive zoo tshaj plaws, thiab cov ntaub ntawv ua tiav, peb ntawm XieJin abrasives tsis txhob ua kom dawb huv peb cov qauv abrasive. Peb cov kev cog lus rau kev txhim kho kom ua kom muaj kev txhim kho kom ua kom peb cov khoom uas peb cov khoom muaj kev ua haujlwm zoo tshaj plaws thiab kev lag luam polishing thiab sib tsoo. Yog tias koj xav tau cov ntaub ntawv ntxiv ntsig txog peb cov khoom lag luam, thov xa kev nug peb los ntawm cov ntaub ntawv tiv toj!
