Alumina hollow npas yog hom tshiab ntawm cov khoom siv rwb thaiv tsev kub. Lawv yog ua los ntawm industrial alumina smelted thiab tshuab nyob rau hauv ib tug hluav taws xob rauv. Daim ntawv siv lead ua yog a-Al2O3 microcrystals. Siv alumina hollow npas ua lub cev tseem ceeb, nws tuaj yeem ua rau cov khoom ntawm ntau yam duab. Qhov siab tshaj plaws ua haujlwm kub yog 1800 degree. Lub zog txhua yam ntawm cov khoom yog siab, ob peb zaug ntawm cov khoom sib sib zog nqus zoo tib yam, thiab lub ntim ntim tsuas yog ib nrab ntawm cov khoom corundum.
Nws tau dav siv nyob rau hauv high-temperature thiab ultra-high-temperature kilns xws li gasifiers nyob rau hauv petrochemical kev lag luam, carbon dub industrial reactors, thiab induction furnaces nyob rau hauv metallurgy kev lag luam, thiab tau ua tiav heev txaus siab rau lub zog txuag.

qhov zoo ntawm alumina npuas cib
-
Kev khiav hauj lwm kub: Nws tuaj yeem ncav cuag tshaj 1750 degrees thiab muaj thermal stability zoo. Cov kab rov ua dua tshiab muaj qhov hloov pauv me me thiab tuaj yeem siv tau ntev dua.
-
Txhim kho cov qauv thiab txo qhov hnyav ntawm lub cub tawg: Cov khoom siv kub-resistant tam sim no yog cov cib hnyav nrog lub ntim ntim ntawm 2.6-3.0g / cm, thaum alumina hollow pob cib tsuas yog 1.1 ~ 1.5g / cm. Rau tib lub cubic meter ntawm ntim, siv alumina hollow pob cib tuaj yeem txo qhov hnyav los ntawm 1.1-1.5g / cm. 1.9 tons hnyav.
-
Txuag cov ntaub ntawv: Yuav kom ua tiav qhov kev khiav hauj lwm kub, tus nqi ntawm cov cib hnyav yog sib npaug ntawm cov alumina hollow pob cib, thiab cov khoom siv hluav taws xob ntau cov txheej txheem refractory kuj tseem yuav tsum tau. Yog siv alumina hollow pob cib, 1.
-
Txuag lub zog: Alumina Bubble bricks muaj cov cuab yeej thermal rwb thaiv tsev thiab cov thermal conductivity tsawg, uas tuaj yeem muaj cov thermal rwb thaiv tsev zoo, txo cov cua sov dissipation, thiab txhim kho thermal efficiency, yog li txuag lub zog. Kev txuag hluav taws xob tuaj yeem ncav cuag ntau dua 30%.
daim ntawv thov ntawm alumina npuas cib
Alumina Bubble Cib thiab lawv cov khoom yog cov khoom siv hluav taws xob sib zog nrog kev kub siab thiab kev txuag hluav taws xob zoo heev. Lawv ruaj khov heev nyob rau hauv ntau yam cua. Tshwj xeeb tshaj yog haum rau cov ntawv thov nyob rau hauv high-kub kilns ntawm 1800 degree.
Alumina Bubble Brick can be used as high-temperature and ultra-high-temperature insulation fillers, high-temperature refractory concrete lightweight aggregates, high-temperature castables, etc. Alumina core ball bricks can be used in high-temperature energy-saving (>30%) inverted nplaim taws kilns, shuttle kilns, molybdenum hlau furnaces, tungsten rod furnaces, induction furnaces, nitriding furnaces, thiab lwm yam. Nws yuav ua tau kom pom tseeb tshwm sim nyob rau hauv txo qhov hnyav ntawm lub cub tawg lub cev, hloov cov qauv, txuag cov ntaub ntawv thiab txuag zog.
