Activated alumina yog ib qho ntawm cov khoom siv tshuaj inorganic siv dav hauv ntiaj teb. Vim nws cov qauv ntxeem tau, siab tshwj xeeb ntawm thaj chaw thiab tsis ruaj khov ntawm kev hloov pauv, nws muaj kev ua haujlwm zoo. Nws yog dav siv los ua catalyst thiab catalyst cab kuj nyob rau hauv petrochemical thiab tshuaj chiv industries.
Activated alumina kuj muaj cov yam ntxwv adsorption, yog li nws tuaj yeem siv los ua desiccant rau roj thiab kua, adsorbent rau roj purification, fluoride Remover rau cov dej haus, xim thiab tsw Remover rau industrial dej phwj, thiab lwm yam. Niaj hnub no, lub ntsiab industrial activated alumina khoom yog tsim. los ntawm lub cev qhuav dej sai.
Nws yog hais txog kev sib tsoo zoo nrog cov khoom siv lead ua qub ntawm 1 μ M α- Al2O3 yog calcined alumina nrog cov ntsiab lus tseem ceeb (20% - 90%). Nws muaj cov khoom me me me me, purity siab, siab dispersion α- Al2O3, uas muaj qhov tshwj xeeb ntawm qhov chaw qis thiab kub kub resistant inertia, tsis yog rau activated alumina thiab muaj me ntsis catalytic.
Nws muaj zog tiv taus cua sov, zoo formability, ruaj khov siv lead ua theem, siab hardness thiab zoo seem stability. Nws tuaj yeem siv los ua kom muaj zog thiab tawv txhua yam ntawm cov yas, roj hmab, ceramics, refractories thiab lwm yam khoom, tshwj xeeb tshaj yog los txhim kho lub compactness, smoothness, txias thiab kub qaug zog, tawg toughness, creep resistance thiab hnav tsis kam ntawm cov khoom polymer.
vim α Phase alumina kuj yog cov khoom siv hluav taws xob nyob deb-infrared nrog kev ua tau zoo heev. Raws li deb-infrared emission thiab thermal rwb thaiv tsev cov ntaub ntawv, nws yog siv nyob rau hauv cov tshuaj fiber ntau thiab high-pressure sodium teeb. Tsis tas li ntawd, α Phase alumina muaj kev tiv thaiv siab thiab kev ua haujlwm zoo rwb thaiv tsev. Nws tuaj yeem siv rau hauv cov khoom siv tseem ceeb ntawm YGA laser siv lead ua thiab kev sib xyaw ua ke hauv substrate.
Cov tsos ntawm activated alumina lim khoom yog dawb kheej kheej, uas yog tsim los ntawm cov txheej txheem tshwj xeeb. Vim nws cov qauv pob txha tshwj xeeb, nws muaj kev sib raug zoo nrog cov khoom siv. Lub pob activated alumina muaj qhov sib txawv ntawm micropore tis, qhov pore loj, qhov pore loj, nqus dej siab, me me ntom ntom, zoo mechanical kev ua tau zoo thiab ruaj khov zoo. Nws yog tsim rau desiccant, catalyst carrier, fluoride tshem tawm tus neeg sawv cev Pressure viav vias adsorbent.
Lub Co-Mo sulfur resistant hloov catalyst npaj nrog cov khoom no muaj cov yam ntxwv ntawm kev ua haujlwm kub tsis zoo, kev ua haujlwm kub ntau thiab lub sijhawm luv vulcanization. Lub catalyst yog haum rau me me thiab nruab nrab-qhov loj me ammonia nroj tsuag.
