Thaum Fused Alumina (Al2O3Ntau tshaj los yog sib npaug rau 99.3%) tseem hu ua dawb fused corundum, nws tau los ntawm fusion ntawm siab purity calcined alumina nyob rau hauv hluav taws xob arc furnaces.
Dawb fused alumina yog dav siv los ua raw khoom hauv refractories, ceramics duab, sib tsoo log, sandpaper, blasting media, hlau npaj, laminates, coatings, lapping, polishing, sib tsoo thiab pua pua ntawm lwm yam kev siv. Dawb fused alumina npuas, nplej thiab hmoov muaj nyob rau hauv cov qauv mesh, grit thiab hmoov ntau thiab tsawg thiab lawv kuj tuaj yeem ua rau tus kheej specifications.
Muaj particle loj xws li: 0-1mm; 1-3 hli; 3-5 hli; 5-8mm; hmoov los yog raws li tus neeg yuav tsum tau muaj.
Cov yam ntxwv tseem ceeb muaj xws li High hardness, High purity thiab whiteness, Zoo tus kheej -sharpening rau abrasion, muaj zog sib tsoo muaj peev xwm, Acid-alkali corrosion kuj, kub tsis kam thiab zoo thermal stability.
Dawb fused alumina yog cov khoom siv siab tshaj -refractory muaj peev xwm tiv taus qhov kub thiab txias thiab tshuaj corrosion. Nws yog ua los ntawm alumina, zirconia thiab lwm yam ntaub ntawv. Nws muaj cov yam ntxwv ntawm siab hardness, siab melting point, siab thermal conductivity, thiab zoo heev tshuaj stability. Nws yog dav siv nyob rau hauv high - kub furnaces, sulfuric acid thiab lwm yam muaj zog acids.
1. Kev tshuaj xyuas cov khoom nyoos thiab kev sib xyaw: Kho qhov sib piv ntawm cov khoom siv raw raws li qhov sib txawv ntawm daim ntawv thov kom tau txais cov khoom tiav nrog cov khoom tshwj xeeb.
2. Kev npaj pwm: Nws yog ib qho tsim nyog los xaiv cov khoom tsim nyog thiab cov txheej txheem ua cov pwm tsim raws li qhov xav tau tiag tiag.
3. Kev tsim cov txheej txheem: Nws yog ib qho tsim nyog yuav tsum ua kom tau raws li cov khoom ntim thiab tsim nyog kom tsis txhob muaj teeb meem zoo xws li huab cua npuas thiab tawg.
4. Sintering kev kho mob: Cov tsim dawb corundum qhov chaw yuav tsum tau sintered kom cov raw khoom molecules sib xyaw ua ke thiab tsim ib tug siab - ntom crystal qauv.
5. Kev ua haujlwm thiab kev sim: Tom qab sintering, cov khoom tiav corundum dawb yuav tsum tau ua tiav thiab kuaj.
