Raws li kev lag luam hlau thiab hlau them nyiaj ntau dua thiab ntau dua rau kev txuag hluav taws xob thiab kev txo qis, cov khoom siv hluav taws xob thiab cov khoom siv tau tsim nyob rau hauv cov kev taw qhia ntawm lub teeb yuag thiab thermal conductivity tsawg, yog li cov khoom hloov kho ntawm "sintered fused alumina"-zog-txuag lub teeb yuag microporous corundum yog kab rov tav yug.
Microporous corundum yog tsim los ntawm kev lag luam alumina, aluminium hydroxide thiab -Al2O3micropowder ua cov ntaub ntawv tseem ceeb, ntxiv cov khoom sib xyaw tsim nyog, thiab tua hluav taws hauv lub qhov cub kub kub. Cov khoom muaj qhov pom tseeb tsis tshua muaj porosity, siab zog, thiab thermal shock kuj. Zoo, siab refractoriness thiab lwm yam. Piv nrog rau qhov zoo tib yam sintered fused alumina, nyob rau hauv lub premise tias lub zog thiab corrosion kuj yeej ib yam, los ntawm kev txhim kho lub internal kaw micropores, txo cov thermal conductivity thiab structural thermal stress ntawm cov khoom, lub thermal rwb thaiv tsev kev ua tau zoo thiab thermal poob siab kuj ntawm cov khoom. cov ntaub ntawv zoo dua. Nws tuaj yeem siv los ua ib feem lossis tag nrho hloov pauv cov sintered fused alumina zoo tib yam hauv cov khoom siv refractory xws li ladle phab ntsa thiab hauv qab castables, prefabricated qhov chaw, thiab lub rooj bricks, thiab lub zog thiab corrosion kuj ntawm refractory khoom tsim los ntawm kev siv microporous corundum yuav tsis txo, thiab Nws kuj tseem muaj cov thermal poob siab zoo dua, thermal conductivity tsawg, thiab txuag hluav taws xob thiab thermal rwb thaiv tsev.
Txawm hais tias microporous corundum tuaj yeem hloov sintered fused alumina hauv txoj kev xav, nws tseem nyuaj heev rau cov tuam txhab siv sintered fused alumina los xaiv cov nqi siab tshiab microporous corundum nyob rau hauv kev poob qis hauv kev lag luam refractory saw lag luam. , nws yog tsis yooj yim sua rau microporous corundum hloov tag nrho sintered fused alumina, thiab kev lag luam txoj hauj lwm ntawm sintered fused alumina tsis tuaj yeem shaken. Txawm li cas los xij, cov tuam txhab tuaj yeem ntsib nws ntsiag to, thiab yuav tsum tsis txhob tso tseg cov khoom lag luam microporous corundum, thiab tsis txhob ua qhov muag tsis pom qhov project microporous corundum. Tom qab tag nrho Cov Kev Loj Hlob Loj yog qhov tam sim no ntawm cov khoom siv kev loj hlob.
