Dawb Fused Alumina

Dawb fused alumina yog ib hom khoom siv refractory tsim los ntawm fusion ntawm calcined alumina hauv hluav taws xob arc rauv ntawm qhov kub ntawm li 2, 000 degree Celsius. Nws muaj lub siab refractoryness thiab yog ib qho nyuaj heev thiab resistant, ua rau nws yog ib qho zoo tagnrho cov ntaub ntawv rau daim ntaub ntawv uas yuav tsum tau high-temperature tiv taus kub thiab durability. Dawb fused alumina yog ib qho khoom siv refractory siv nyob rau hauv cov chaw tsim hluav taws xob, cov nroj tsuag cement, thiab lwm yam lag luam uas yuav tsum tau siv cov khoom siv hnyav.

Ib qho txiaj ntsig tseem ceeb ntawm dawb fused alumina yog nws purity. Raws li qhov kawg yuav tsum tau ua, WFA tuaj yeem tsim hauv Higgins lossis qaij rauv taws. Muaj ntau hom WFA sib txawv purity, thiab Delk muaj peev xwm xa cov qauv refractory thiab abrasive qib ntau thiab tsawg. Delk's dawb fused alumina cov khoom siv dav siv hauv cov hlau, tshuaj, cement, thiab lwm yam lag luam.

Dawb fused alumina paub txog nws cov purity siab, uas txhais tau tias nws muaj tsawg heev los yog tsis muaj impurities. Qhov no yog vim hais tias nws yog tsim los ntawm high-temperature thiab high-pressure txheej txheem, uas tshem tawm tag nrho cov impurities los ntawm raw cov ntaub ntawv. Qhov purity no ua rau dawb fused alumina xaiv ib puag ncig zoo dua, vim nws tsis muaj silica, uas yog cov khoom siv phom sij.

Ntxiv rau nws cov purity, dawb fused alumina kuj paub txog nws hardness thiab tsis kam mus rau tshav kub. Qhov no ua rau nws yog ib qho khoom siv zoo tshaj plaws rau cov ntawv thov uas yuav tsum tau ua haujlwm hnyav thiab siv tau ntev. Dawb fused alumina muaj qhov melting point ntawm ib ncig ntawm 2200, uas txhais tau hais tias nws tuaj yeem tiv taus qhov kub thiab txias yam tsis muaj degrading ..

Ib qho ntawm cov ntawv thov tseem ceeb ntawm dawb fused alumina yog nyob rau hauv kev tsim cov castables refractory. Cov no yog siv nyob rau hauv daim ntawv thov xws li rauv hauv ob sab phlu, refractory cib, thiab refractory vuas. Dawb fused alumina tuaj yeem siv los ua refractory castable hauv qhov ntau thiab tsawg: Ntu xuab zeb: 0-1mm, 1-3mm, 3-5mm
