Alumina hollow spheres yog tsim los ntawm kev lag luam alumina los ntawm melting thiab tshuab hauv lub cub hluav taws xob, thiab cov khoom siv lead ua yog a-Al2O3microcrystals. Nrog alumina hollow spheres ua lub cev tseem ceeb, nws tuaj yeem ua rau ntau yam kev qhia tshwj xeeb ntawm cov khoom siv hluav taws xob thiab cov khoom siv hnyav, qhov siab tshaj plaws kev khiav hauj lwm kub yog 1800 degree C, lub zog txhua yam yog siab, thermal conductivity yog tsawg, thiab cov kev ua tau zoo yog ruaj khov nyob rau hauv ntau yam. huab cua.
Qhov zoo ntawm Alumina Hollow Spheres
1. Kev khiav hauj lwm kub: mus txog 1750 degrees los yog ntau tshaj, nrog zoo thermal stability. Cov kab rov ua dua tshiab muaj qhov hloov pauv me me thiab tuaj yeem siv tau ntev dua.
2. Ua kom zoo rau cov qauv thiab txo qhov hnyav ntawm lub cub tawg: cov khoom siv hluav taws xob kub kub yog tag nrho cov cib hnyav nrog qhov ntom ntom ntawm 2.6-30g / cm, thaum lub pob alumina hollow cib tsuas yog 1.
3. Cov khoom txuag: ntawm tib qhov kev ua haujlwm kub, kev siv cov alumina hollow pob cib tuaj yeem txuag tau 1. .
4. Kev txuag hluav taws xob: Alumina hollow spheres muaj cov cuab yeej thermal rwb thaiv tsev, tsis tshua muaj thermal conductivity, txo cov cua sov dissipation, tuaj yeem ua tau zoo thermal rwb thaiv tsev, txhim kho thermal efficiency, thiab ua tiav lub hom phiaj ntawm kev txuag hluav taws xob, thiab txuag hluav taws xob tuaj yeem ncav cuag ntau dua. tshaj 30 feem pua.
Kev siv Alumina Hollow Spheres
1. Alumina hollow spheres thiab lawv cov khoom yog lub teeb yuag cov ntaub ntawv refractory nrog kub tsis kam thiab zoo heev zog txuag.
2. Alumina hollow spheres yog cov khoom siv rwb thaiv tsev zoo tagnrho rau cov cua kub kub, rwb thaiv tsev kub thiab lub zog txuag cov ntaub ntawv refractory. Nws tuaj yeem siv los ua qhov kub thiab txias, ultra-siab kub rwb thaiv tsev muab tub lim, kub kub refractory qhob sib xyaw ua ke, kub castable, thiab lwm yam.
3. Alumina hollow npas yog dav siv nyob rau hauv high kub thiab ultra-siab kub furnaces xws li petrochemical industrial gasifiers, carbon dub industrial cov tshuaj tiv thaiv rauv, thiab metallurgical industrial induction furnaces.
4. Alumina hollow ball refractory bricks can be used for high temperature energy saving (>30 feem pua) industrial furnaces.
