Abrasives yog dab tsi? Nws ua qhov txawv li cas?
Abrasive cov cuab yeej yog cov cuab yeejsiv rau kev sib tsoo, sib tsoo thiab polishing. Feem ntau cov abrasives yog cov khoom siv abrasives ua los ntawm abrasives thiab binders. Ntxiv nrog rau kev siv dav hauv kev tsim khoom thiab lwm yam kev lag luam hlau, cov cuab yeej abrasive kuj tseem siv rau hauv kev ua qoob loo, kev lag luam ntawv thiab kev ua cov ntaub ntawv tsis yog xim hlau xws li ceramics, iav, pob zeb, yas, roj hmab thiab ntoo.
Ceramic daim ntawv cog lus - Lub zog ntawm daim ntawv cog lus no rau cov abrasive zoo dua li cov resin. Tom qab tsim cov cuab yeej sib tsoo, qhov chaw ua haujlwm muaj peev xwm zoo, yog li nws tsis yooj yim rau ntsaws, ntse txiav, kev sib tsoo siab, thiab thermal expansion me me, yooj yim los tswj cov kev ua haujlwm raug, uas yog qhov zoo rau kev sib tsoo. txheej txheem. Nyob rau hauv lub shaping thiab hnav khaub ncaws ntawm cov cuab yeej abrasive, nws yog ib qho yooj yim rau kev khiav lag luam, feem ntau yog siv rau kev sib tsoo ntxhib, semi-zoo sib tsoo, thiab molding sib tsoo nrog loj qhov chaw, thiab lwm yam.
Hlau binders - suav nrog bronze binders thiab electroplating binders ob pawg. Electroplating binder yog ib daim ntawv cog lus nrog lub zog siab dua, feem ntau ib leeg lossis ntau txheej ntawmabrasiveParticles plated ntawm cov hlau matrix los ntawm txoj kev electroplating, tus naj npawb ntawm abrasive hais ib cheeb tsam ntawm qhov chaw ua hauj lwm ntawm cov binder sib tsoo cov cuab yeej yog ntau ntau dua li ntawm lwm yam ob peb binders, thiab cov abrasive hais raug rau saum npoo ntawm chu binder. , yog li txiav yog ntse thiab kev sib tsoo efficiency siab. Txawm li cas los xij, vim qhov txwv tsis pub muaj txheej txheej, tag nrho cov kev pab cuam lub neej ntawm cov cuab yeej sib tsoo tsis siab, xws li molding sib tsoo cov cuab yeej, me me sib tsoo taub hau, nesting riam, electroplating reamer, cov ntaub ntawv thiab lwm yam. Nrog rau kev nce qib ntawm cov thev naus laus zis tsis tu ncua, daim ntawv thov ntawm cubic boron nitride electroplating hlau bonding abrasives nthuav dav ib hnub.
Abrasive khoom feem ntau muab faib ua corundum abrasives thiab silicon carbide abrasives ob pawg, subdivided rau hauv ntau yam hauv qab no.
1, xim av corundum abrasive, lub ntsiab tivthaiv yog Al2O3, nrog rau nruab nrab hardness, toughness, particle ntse, kuj tsis tshua muaj nqi, haum rau ua high tensile zog hlau.
2, xim av corundum abrasive, nws hardness yog me ntsis siab dua xim av corundum, tab sis lub toughness yog tsis zoo, yooj yim rau txiav mus rau hauv lub workpiece thaum sib tsoo, zoo tus kheej-sharpening, me me tshav kub, muaj zog sib tsoo muaj peev xwm, high efficiency.
3, ib leeg siv lead ua corundum abrasive, nws cov khoom yog tsim los ntawm ib qho siv lead ua, thiab muaj qhov zoo ntawm ntau cov ntug txiav, siab hardness thiab toughness, sib tsoo muaj peev xwm, sib tsoo kub tsawg, qhov tsis zoo yog tias cov nqi tsim khoom siab, cov zis tawm. yog tsawg, yog li tus nqi kuj siab.
4, dub silicon carbide abrasives, ntsuab silicon carbide abrasives, cubic silicon carbide abrasives, cerium silicon carbide abrasives, thiab lwm yam., belongs rau silicon carbide abrasives.
