Daim ntawv thov
1.Pigments:
Chromium (III) oxide ntsuab yog siv nyob rau hauv cov teb xws li coatings, ceramic enamel, tshwj xeeb xim, camouflage coatings, ntsuab flooring, ntsuab iav, thiab xim cement.
2. Polishing abrasive:
Chromium (III) oxide ntsuab tuaj yeem ua rau hauv cov ntaub ntawv polishing rau kev sib tsoo thiab polishing stainless hlau, gemstones, machinery, instruments, meters, moos thiab pob bearings.
3.Refractory khoom:
Chromium (III) oxide ntsuab yog siv ncaj qha los ua cov khoom siv refractory, thiab feem ntau ntxiv rau corundum lossis corundum spinel refractory cov ntaub ntawv, nws tuaj yeem txhim kho nws qhov kub thiab txias kev ua tau zoo, slag yaig kuj, thiab lwm yam khoom. Dav siv nyob rau hauv cov teb xws li refractory cib, siab chromium cib, magnesium chromium cib, ramming cov ntaub ntawv, castables, high-temperature coatings, fireclay, thiab lwm yam.
4.Electrofusion:
Chromium (III) oxide ntsuab yog siv rau hauv cov hluav taws xob melting, siv nyob rau hauv non-ferrous metallurgy, tsev cov ntaub ntawv, petrochemical kev lag luam, loj fais fab nroj tsuag, khib nyiab incinerators, thiab lwm yam teb. Nws kuj tseem tuaj yeem siv los ua cov txheej txheej yaj, txau ncaj qha mus rau saum npoo ntawm cov hlau, ceramics, thiab lwm yam ntaub ntawv siv cov roj plasma kub kub, ua rau cov khoom siv siab heev, tiv thaiv corrosion, thiab kub tsis kam. Raws li kev xav tau, chromium oxide ntsuab tuaj yeem sib xyaw nrog alumina lossis zirconia los ntawm hluav taws xob melting los tsim cov ntaub ntawv refractory nrog kev ua haujlwm zoo.
