Brown corundum ua li cas? Cov haujlwm ntawm xim av corundum yog dab tsi?
Brown corundum yog cov khoom siv polishing tshiab uas feem ntau siv hauv peb cov khoom lag luam, tab sis ntau tus phooj ywg tsis paub qhov twg xim av corundum kuj siv tau?
Brown corundum yog siv cov bauxite, carbon cov ntaub ntawv, hlau chips peb raw cov ntaub ntawv nyob rau hauv lub hluav taws xob rauv melting txo thiab ua los ntawm cov xim av dag corundum, xim av corundum abrasive, zoo hnav tsis kam, zoo hardness, zus tau tej cov qib, ob, xim av corundum ntau lub npe tseem hu ua emery. Cov tshuaj muaj pes tsawg leeg yog AL2O3, nws cov ntsiab lus yog 94.5% -97%, thiab muaj me me ntawm Fe, Si, Ti thiab lwm yam. Los ntawm kev xyaum ntawm ntau lub tuam txhab refractory ntau lawm, cov khoom muaj cov yam ntxwv ntawm tsis muaj pib, tsis muaj pulverization thiab tsis muaj cracking nyob rau hauv daim ntawv thov txheej txheem. Tshwj xeeb, nws cov nqi kev ua tau zoo yog ntau dua li ntawm cov khoom siv ib txwm siv, uas ua rau nws cov khoom sib xyaw ua ke zoo thiab muab tub lim kom zoo dua refractories.
Xim av corundum yog tan, uas qib peb xim av corundum feem ntau hu ua dub corundum xim yog tsaus. Nws muaj cov yam ntxwv ntawm siab purity, zoo crystallization, muaj zog fluidity, tsawg coefficient ntawm linear expansion thiab corrosion kuj. Cov khoom tseem ceeb ntawm cov khoom yog alumina, thiab kev faib tawm yog sib txawv los ntawm cov ntsiab lus ntawm aluminium, thiab cov ntsiab lus ntawm aluminium qis, qhov qis dua qhov hardness; Cov khoom me me yog tsim raws li cov qauv thoob ntiaj teb thiab cov qauv hauv tebchaws, thiab tuaj yeem ua tiav raws li cov neeg siv khoom xav tau. Qhov loj me me yog F4 -- F320, thiab nws cov tshuaj muaj pes tsawg leeg sib txawv nyob ntawm seb qhov loj me me. Qhov zoo tshaj plaws feature yog hais tias cov siv lead ua loj me me thiab cuam tshuam resistant, vim hais tias ntawm crushing txheej txheem nrog lub automill, cov hais yog feem ntau spherical hais, qhov saum npoo yog qhuav thiab huv si, thiab nws yog ib qho yooj yim los mus ua ke nrog cov binder.
Kev siv loj ntawm cov xim av corundum: cov khoom siv ua haujlwm, cov xuab zeb blasting lub hom phiaj txheej txheem yuav tsum tau ua. Stainless hlau, nto decontamination, vuam slag tshem tawm thiab matte nyhuv. Hlau workpiece, xeb, av, oxide tshem tawm, ua kom cov txheej txheej, txheej adhesion. Aluminium workpiece, tshem tawm daim tawv nqaij, deg ntxiv dag zog, ua tiav.
Brown corundum yog lub npe hu ua cov hniav ntawm kev lag luam: feem ntau yog siv rau hauv cov ntaub ntawv refractory, sib tsoo log, sandblasting. Dav siv nyob rau hauv txhuas profile, tooj liab profile iav, ntxuav ris precision pwm thiab lwm yam teb; Nws yog kev sib tsoo qib abrasive, siv nyob rau hauv ntau qhov chaw ntawm kev sib tsoo dawb, yog siv dav hauv cov khoom siv sib tsoo hauv tsev; Nws yog cov khoom siv raw ntawm cov ntawv xuab zeb, gauze thiab lwm cov tuam ntxhab; Nyob rau tib lub sijhawm, nws kuj tseem yog siv rau tsheb nres qhov chaw, cov log tsheb tshwj xeeb, cov khoom siv tshwj xeeb, thiab lwm yam. Nws tuaj yeem siv los ua cov khoom hnav-tiv taus rau lub tsev loj pavement, airstrip, chaw nres tsheb, chaw nres tsheb, hauv pem teb, kev ua si. teb thiab lwm yam.
