Puas yog Brown Aluminium Oxide Hloov Dawb Txhuas Oxide Hauv Kev Lag Luam Cov Khoom Siv Refractory?

Sebxim av aluminium oxidetuaj yeem hloovdawb aluminium oxidenyob rau hauv cov ntaub ntawv refractory kev lag luam nyob ntawm tej daim ntawv thov yuav tsum tau thiab kev ua tau zoo specifications. Cov hauv qab no yog ib qho kev ntsuam xyuas ntxaws ntawm qhov teeb meem no:

1. Qhov txawv tseem ceeb ntawm Brown aluminium oxide thiab dawb txhuas oxide

• Brown Fused Alumina:

Ntau dua toughness, me ntsis qis hardness, zoo cuam tshuam thiab thermal shock kuj, haum rau nruab nrab thiab qis kub ib puag ncig.

• Dawb Fused Alumina:

Ntau dua purity, muaj zog hardness, zoo heev -kub tsis kam, haum rau huab cua kub - kub thiab corrosive ib puag ncig.

2. Cov xwm txheej qhov twg Brown aluminium oxide tuaj yeem hloov dawb txhuas oxide

Scenario Qhov twg Nws tuaj yeem hloov tau:

1. Nruab nrab- thiab qis- Ib puag ncig kub:

Yog tias cov khoom siv refractory yog siv nyob rau hauv nruab nrab - thiab qis- qhov kub thiab txias ib puag ncig (feem ntau hauv qab 1600 degree), xws li hauv cov khoom siv hluav taws xob zoo tib yam lossis nruab nrab- thiab qis- qhov kub ntawm lub qhov cub, qhov kev ua tau zoo ntawm cov xim av fused alumina yog txaus kom ua tau raws li qhov yuav tsum tau ua thiab nws tuaj yeem hloov tau dawb fused alumina.

2. Kev Tiv Thaiv Kev Tiv Thaiv Siab:

Nyob rau hauv cov ntawv thov uas yuav tsum tau muaj zog dua los yog thermal shock kuj, xws li nyob rau hauv industrial kilns qhov twg lub qhov cub hauv ob sab phlu feem ntau raug hloov kub, xim av fused alumina yuav yog ib qho kev xaiv zoo dua.

3. Tus nqi txwv:

Yog tias cov peev nyiaj tsawg thiab qhov siab - qhov yuav tsum tau muaj kev ruaj ntseg kub rau cov khoom siv refractory tsis nruj heev, xim av fused alumina, raws li cov khoom siv qis, tuaj yeem siv los ua lwm yam.

Cov xwm txheej uas nws tsis tuaj yeem hloov tau:

1. Kev kub siab heev - ib puag ncig kub:

Yog tias cov khoom siv refractory yog siv nyob rau hauv siab - kub (siab tshaj 1600℃) los yog ultra- siab - kub (xws li, saum 1800℃) ib puag ncig, xws li metallurgical blast furnaces los yog siab - kub furnaces nyob rau hauv petrochemical industries siab {8} siab stability, fused alumina yog qhov tseem ceeb, thiab xim av fused alumina hloov tsis tau.

2. High oxidizing thiab corrosive ib puag ncig:

Nyob rau hauv ib cheeb tsam tshwj xeeb uas yuav tsum tau muaj zog oxidation los yog corrosion (xws li roj av refining khoom los yog semiconductor rauv linings), lub siab purity thiab oxidation tsis kam ntawm dawb fused alumina ua rau nws ib tug irreplaceable xaiv.

3. High precision yuav tsum:

Yog hais tias cov khoom siv refractory yuav tsum muaj cov ntsiab lus tsis muaj paug tsawg heev kom tsis txhob muaj cov kab mob sib kis los yog cuam tshuam rau cov txheej txheem (xws li cov khoom siv hluav taws xob ua kom siab- purity iav los yog ceramics), dawb fused alumina yog qhov tsim nyog dua vim tias nws cov purity siab, thaum xim av fused alumina tuaj yeem ua rau kev ua haujlwm tsis zoo.

3. Kev sib piv thiab daim ntawv thov kev pom zoo ntawm cov xim av aluminium oxide thiab dawb aluminium oxide

Brown aluminium oxide tuaj yeem hloov dawb aluminium oxide nyob rau hauv cov ntaub ntawv refractory kev lag luam nyob rau hauv nruab nrab thiab qis kub, tsis yog - ib puag ncig heev, thiab ua tau zoo tshwj xeeb tshaj yog nyob rau hauv cov nqi -sensitive tej yaam num. Txawm li cas los xij, hauv cov ntawv thov uas xav tau qhov kub thiab txias, siab purity, thiab siab oxidation tsis kam, dawb fused alumina tseem yog qhov kev xaiv tsis raug.
