Chrome corundum

Chrome corundum (eo hape e tsejoang e le pinki corundum) e entsoe ka metallurgical grade chrome green le alumina ea indasteri e le lisebelisoa tse tala, 'me lik'hemik'hale li itšoara ka mocheso o phahameng ka holimo ho likhato tse 2000.Palo e itseng ea chromium oxide e eketsoa nakong ea ts'ebetso ea ho qhibiliha, e leng bopherese bo bobebe kapa rose.

Ts'ebetso e pharaletseng ea lihlahisoa tsa chromium corundum e na le litšobotsi tsa ho thatafala ho phahameng, boima bo phahameng, bohloeki bo phahameng, ho itšeha ka mokhoa o babatsehang, bokhoni bo matla ba ho sila, mocheso o fokolang oa mocheso, bokhoni bo phahameng, ho hanyetsa acid le alkali, ho hanyetsa mocheso o phahameng, le botsitso bo botle ba mocheso.

Ho chromium corundum, kenyelletso ea Cr element e ntlafatsa ho tiea ha abrasive.Boima bo tšoana le ba corundum e tšoeu, 'me boima bo phahame ho feta ba white corundum.Lisebelisoa tsa abrasive tse entsoeng ke eona li na le nako e ntle ea nako e telele le qetello e phahameng ea ho qetela.E sebelisoa haholo ho li-abrasives, ho sila, lisebelisoa tsa ho bentša, lehlabathe le nepahetseng, lisebelisoa tsa ho fafatsa, li-catalyst catalyst carriers, li-ceramics tse khethehileng, joalo-joalo. Mabaka a sebetsang a kenyelletsa: ho sila ka mokhoa o nepahetseng oa lisebelisoa tsa ho lekanya, li-spindle tsa lisebelisoa tsa mochine, likarolo tsa lisebelisoa, lisebelisoa tse entsoeng ka khoele, le ho sila mohlala. .

Chromium corundum e na le viscosity e phahameng le khanyetso e ntle ea ho kenella ka lebaka la karolo ea khalase e nang le chromium oxide, e ka thibelang haholo ho khoholeha le ho kenella ha slag e qhibilihisitsoeng.E boetse e sebelisoa haholo masimong a mocheso o phahameng a nang le tikoloho e thata, ho kenyelletsa le libopi tsa tšepe tse se nang ferrous, likhalase tse qhibilihisang likhalase, li-reactors tse ntšo tsa carbon, li-incinerators tsa lithōle, li-castable tse refractory le tse ling tse hanyetsanang le mocheso o phahameng le tšireletso ea kutu.
