Brown fused alumina grit rau sandpaper sib tsoo log coated abrasive
Brown fused alumina / Brown corundum, feem ntau hu ua emery, yog xim av dag corundum ua los ntawm melting thiab txo peb cov ntaub ntawv raw: bauxite, carbon cov ntaub ntawv thiab hlau filings nyob rau hauv ib tug hluav taws xob arc rauv, li no lub npe.Nws cov ntsiab lus tseem ceeb yog alumina, thiab cov qib kuj txawv ntawm cov ntsiab lus txhuas.Qhov qis ntawm cov ntsiab lus aluminium, 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 siv lead ua loj me me thiab cuam tshuam resistant.Vim tias nws tau ua tiav thiab tawg los ntawm lub tshuab nws tus kheej sib tsoo, cov khoom feem ntau yog spherical hais.Qhov saum npoo yog qhuav thiab huv si, thiab nws yog ib qho yooj yim rau kev sib txuas nrog cov binder.Brown fused alumina yog ua los ntawm cov qib abrasive bauxite ua raw khoom thiab ntxiv nrog cov khoom pabcuam.Nws yog refined nyob rau hauv hluav taws xob arc rauv ntawm qhov kub siab tshaj 2250 ℃.Rau lub hauv paus no, nws yog refined los ntawm high-strength magnetic separator thiab nws refractoriness yog siab tshaj 1850 ℃.Cov xim av corundum ua los ntawm peb lub tuam txhab muaj cov yam ntxwv ntawm siab purity, zoo crystallization, muaj zog fluidity, tsis tshua muaj linear expansion coefficient thiab corrosion kuj.Cov khoom muaj cov yam ntxwv ntawm tsis tawg, tsis yog hmoov, thiab tsis tawg thaum lub sij hawm daim ntawv thov, thiab yog feem ntau siv nyob rau hauv abrasives thiab refractory raw khoom industries.

Abrasives cov ntaub ntawv: Sib tsoo log, abrasive siv, sandpaper, abrasive daim ntaub, txiav daim, xuab zeb blasting tshuab, sib tsoo, hnav-resistant pem teb, dej dav hlau txiav, coated abrasives, consolidated abrasives, thiab lwm yam.
Cov khoom siv refractory: Castable, refractory cib, ramming khoom, swb phaj, nozzle, ladle, hauv ob sab phlu khoom.precision casting, thiab lwm yam
Brown corundum yog hu ua cov hniav muaj: feem ntau yog siv nyob rau hauv refractories, sib tsoo log, thiab sandblasting.
1. Siv los tsim cov khoom siv refractory siab heev, castables, refractory bricks, thiab lwm yam.
2. Sandblasting-lub abrasive muaj nruab nrab hardness, siab bulk ntom, tsis muaj silica dawb, siab lub ntiajteb txawj nqus, thiab zoo toughness.Nws yog ib qho zoo tagnrho "ib puag ncig tus phooj ywg" sandblasting khoom.Nws yog dav siv nyob rau hauv aluminium profiles, tooj liab profiles, iav, thiab ntxuav ris.Precision pwm thiab lwm yam kev lag luam;
3. Dawb sib tsoo-sib tsoo qib abrasive, siv rau kev sib tsoo dawb hauv cov duab thaij duab, iav kho qhov muag, monocrystalline silicon, lens, saib iav, siv lead ua iav, jade, thiab lwm yam. Nws yog cov khoom siv qib siab sib tsoo feem ntau siv hauv Suav teb ;
4. Resin Abrasives-Abrasives uas haum xim, zoo hardness, toughness, haum particle cross-section hom thiab ntug tuav, siv rau resin abrasives, cov nyhuv yog zoo tagnrho;
5. Coated abrasives-abrasives yog cov khoom siv raw rau cov chaw tsim khoom xws li cov ntawv xuab zeb thiab cov ntaub qhwv ntsej;
6. Lub tshuab ua haujlwm ua haujlwm-tsuas yog siv rau cov tsheb nres tsheb, cov log tsheb tshwj xeeb, cov khoom siv tshwj xeeb thiab lwm yam dab tshos, uas tuaj yeem siv los ua cov khoom siv tiv thaiv xws li kev khiav, chaw nres tsheb, chaw nres tsheb, chaw ua haujlwm, chaw ua si, thiab lwm yam.;
