Refractory calcined aluminium oxide hmoov
Alumina hmoov / α-Alumina Micropowder
Alumina hmoov yog ib qho inorganic tshuaj nrog cov tshuaj formula Al2O3.Nws yog ib qho nyuaj hardness compound nrog lub melting point ntawm 2054 ° C thiab boiling point ntawm 2980 ° C.Nws yog ib qho siv lead ua ionic uas tuaj yeem ionize ntawm qhov kub thiab txias thiab feem ntau siv los ua cov khoom siv refractory.
Alumina hmoov yog alumina Al2O3 khoom hmoov, feem ntau ua tiav rau α-al2o3 alumina hmoov, β-al2o3 alumina hmoov, γ-al2o3 alumina hmoov raws li kev siv sib txawv.
α-Alumina micropowder
α alumina hmoov muaj qhov ruaj khov ntawm lub cev thiab tshuaj lom neeg, siab hardness, hnav tsis kam, siab mechanical zog, rwb thaiv tsev, kub tsis kam, tsis tshua muaj kub kub, tsawg coefficient ntawm thermal expansion, zoo thermal conductivity thiab lwm yam ntxwv.
α alumina feem ntau yog siv los ua abrasive, toughening agent, refractory cov ntaub ntawv, polishing cov ntaub ntawv, thiab lwm yam.
Txheej txheem ntau lawm
Raw khoom pob zeb: pab tshem tawm impurities, txhim kho qhov hloov pauv ntawm cov txheej txheem tua, thiab ua kom cov tshuaj tiv thaiv ceev;
Tunnel kiln roasting: nruam thiab ruaj khov ntau lawm tuaj yeem paub, thiab qhov kub ntawm qhov cub tuaj yeem tswj tau raug;
Clinker pob zeb: Sib tsoo lub clinker rau hauv qhov xav tau qhov loj me.
