Cia tej yam kev mob yog ib qho tseem ceeb tshaj plaws uas cuam tshuam rau kev ua tau zoo ntawmcoated abrasivecov khoom. Tsuas yog khaws cia kom zoo tuaj yeem tswj xyuas kev sib tsoo zoo.
Lub substrate thiab qee cov nplaum thaum lub sij hawm tsim khoom yog rhiab rau kev nyab xeeb thiab yuav qhuav los yog damp nyob ntawm seb cov av noo ntawm lawv ib puag ncig.
Coated abrasives muaj qhov ua tau zoo tshaj plaws thaum khaws cia thiab siv nyob rau hauv qhov pom zoo kub thiab av noo. Lawv muaj qhov ua tau zoo tshaj plaws ntawm 60 degrees txog 80 degrees Fahrenheit thiab 40%-50% txheeb ze av noo.
Thaum khaws cia, xyuas kom tag nrho cov coated abrasives tsis nyob rau hauv kev sib cuag ncaj qha nrog cov pob zeb hauv pem teb, kom deb ntawm cov dej noo, cov kav dej kub thiab cov cua sov.
Kev cuam tshuam ntawm kev cia khoom tsis zoo:
Cov av noo ntau dhau: Nws yuav ua rau cov binder lossis resin soften, thiab cov khoom muab tub lim hauv matrix kom muag. Nyob rau hauv txoj kev no, thaum lub sij hawm sib tsoo txheej txheem, lub abrasive yuav nias tawm tsam lub matrix es tsis txhob ntawm lub workpiece nyob rau hauv av, txo cov kev sib tsoo efficiency. Frictional cua sov yuav ua rau lub binder softer. Lub neej ntawm coated abrasives yuav raug txo los ntawm 50% yog tias lawv tau khaws cia rau hauv qhov chaw muaj av qeeg ntev.
Overdrying: Nws yuav txo qhov hloov pauv ntawm cov khoom thiab ua rau muaj teeb meem hauv kev siv. Nqaim abrasive siv yuav curl los yog twist thiab ua khob (khoov rau sab nraub qaum) thaum overdried. Cov khoom siv ntawv, tshwj xeeb tshaj yog cov khoom siv hnyav, yuav plam qhov yooj yim thiab ua nkig yog tias khaws cia rau hauv qhov chaw overdry rau lub sijhawm ntev. Dej-resistant sandpaper kuj yuav cuam tshuam los ntawm qhov no.
Rau cov ntaub qhwv cov ntaub qhwv thiab cov discs, yog tias cov dej noo nyob hauv lub hauv paus siab dhau lawm, lawv yuav khoov rau sab nraub qaum thiab ua tsis zoo rau kev siv. Adhesive thiab resin-bonded abrasive siv kuj yuav khoov rau sab nraub qaum yog tias lawv ntub dhau. Yog tias lawv qhuav dhau lawm, lawv yuav khoov rau hauv qhov sib txawv.
Nco tseg:
Ntxiv nrog rau kev ua kom ntseeg tau qhov kub thiab txias rau koj cov coated abrasives, koj yuav tsum tau ua tib zoo mloog rau cov lus qhia tseem ceeb hauv qab no kom ntev lub neej ntawm koj cov coated abrasives tsis siv:
Coated abrasives yuav tsum muab cia rau hauv cov thawv ntim khoom ua ntej siv.
Tej yob yuav tsum muab cia kom tiaj tus thiab tsis stacked. Cartons, thawv thiab ntim yob yuav tsum khaws cia kom zoo thaum siv. Abrasive siv yuav tsum tau dai rau ntawm tshwj xeeb racks.
Kev tsim nyog racking rau koj cov coated abrasives tuaj yeem pab koj tswj koj lub tsev rau khoom.
