Silicon Carbide: Nkag siab txog grit ntau thiab tsawg rau kev ua haujlwm zoo dua
Silicon carbide, renowned rau nws lub siab hardness, tsis nthuav dav cov coefficientity, yog ib qho zoo kawg li tsis yog - nws tsis yog - nws tsis yog - nws tsis yog - nws tsis yog - nws tsis yog - nws tsis yog - nws tsis yog - nws tsis yog - nws tsis yog - nws tsis yog - nws tsis yog - nws yog xim hlau khoom. Nws yog tsim nyob rau ntawm qhov kub siab tshaj 1800 degrees Celstz xuab zeb (sio}, thiab sodium rawicide (nrog so cov xim dub thiab ntsuab ntsuab ua ob hom loj.
Thaum nws los txog silicon carbide abrasive ntau lawm, grit loj yog qhov tseem ceeb heev. Kev lag luam sib txawv thiab cov ntawv thov thov kom muaj feem ntau thiab tsawg kom ua tiav tau cov txiaj ntsig zoo. Muaj ntau cov qauv thoob ntiaj teb rau cov qhov ntau thiab tsawg, xws li Suav Cov Qauv, Cov Qauv European (FEPA), thiab Japanese Cov Qauv (JIS).
Piv txwv li, hauv qab European txheem (FEPA), F8 #, F10 #, F12 #, F12 #, F12 #, thiab lwm cov qauv sib raug rau cov ntsiab lus loj. Piv txwv li, F16 # muaj qhov yooj yim qhov loj me me ntawm 1400 - 1180 microns, thaum f120 # {} {7}} microns. Nyob rau hauv Japanese tus qauv (JIS), 16 # Silicon Carbide muaj cov particle loj ntsig txog 1230 microns kwv yees li, thiab 120 # nyob ib puag ncig 109 microns.
Kev xaiv ntawm grit loj nyob ntawm qhov kev npaj siv. Hauv kev lag luam semiconduct, qhov twg precision yog qhov tseem ceeb, finer grit ntau thiab tsawg yuav tsum muaj rau cov haujlwm zoo li wafer polishing. Nyob rau hauv cov ntawv thov abrasive rau cov kev siv hlau ua haujlwm dav dav, ib coarser grit loj tej zaum yuav haum cov khoom siv sai.
Peb lub tuam txhab muaj cov khoom lag luam siab - cov khoom lag luam zoo silicon uas nruj rau cov qauv hauv ntiaj teb no. Peb xyuas kom meej tias cov thooj qhov ntau thiab tsawg yog qhov tseeb thiab zoo ib yam, lav tau kev txhim khu kev qha hauv koj cov ntawv thov. Txawm hais tias koj xav tau silicon carbide rau cov abrasives, kev ua khoom siv hluav taws xob, lossis lwm yam kev lag luam, peb cov khoom tuaj yeem ua tau raws li koj cov kev xav tau. Tiv tauj peb los kawm paub ntau ntxiv txog peb silicon carbide muaj thiab lawv tuaj yeem txhim kho koj cov txheej txheem ntau lawm.
