Dab tsi yog qhov txawv ntawm qhov xwm txheej ntawm Active Alumina Powder thiab Kub Kub Alumina Hmoov

Kub kub alumina hmoov yog tsim los ntawm kev lag luam aluminium hydroxide thiab bauxite, molecular sieve thiab sib tsoo pob ua raw khoom, thiab yog calcined ntawm kub kub rau lub sij hawm ntev nyob rau hauv lub qhov cub. Thaum lub sij hawm smelting txheej txheem, cov pa roj carbon nyob rau hauv lub anthracite txo impurities xws li silicon oxide (SiO2), hlau oxide thiab titanium oxide nyob rau hauv lub bauxite rau hlau, uas yog ua ke los ua ferroalloys, uas nyob rau hauv qab ntawm lub cub tawg thiab cais los ntawm cov hlau. corundum molten kua vim nws qhov ntom.
Kub kub aluminium oxide hmoov muaj zog crushing tsis kam, oxidation kuj, corrosion kuj, thiab zoo tshuaj stability, thiab yog ib tug dav siv abrasive.

Active aluminium oxide hmoov yog ib qho abrasive ua los ntawm kev lag luam aluminium hydroxide hmoov uas yog rhuab thiab yaj thiab recrystallized nyob rau hauv hluav taws xob arc rauv. Cov impurities hauv cov khoom siv raw tsis suav nrog hauv cov txheej txheem smelting, yog li qhov zoo ntawm activated alumina yog ze ze rau qhov purity ntawm raw cov ntaub ntawv. Cov ntsiab lus ntawm A12O3 nyob rau hauv activated alumina yuav tsum siab tshaj 99.5%, thiab nws hardness yog siab tshaj ntawm high-temperature aluminium oxide hmoov, tab sis nws yog nkig.

Nws muaj kev txiav zoo, oxidation tsis kam thiab roj corrosion, thiab muaj rwb thaiv tsev zoo. Feem ntau yog siv rau hardening steel, alloy steel zoo sib tsoo thiab zoo sib tsoo, sib tsoo threads thiab zog, active aluminium oxide hmoov kuj siv tau rau precision casting thiab high-qib refractory ntaub ntawv.
