Cov pob alumina ua kom muaj ntau yam kev siv thiab cov lus qhia, uas tuaj yeem muab faib ua 5 lub luag haujlwm tseem ceeb.

Alumina desiccant: Nws feem ntau siv cov qhov tsim los ntawm cov pob alumina ua kom muaj zog thiab muaj peev xwm nqus dej tau zoo heev. Nws yuav tsis deform lossis tawg tom qab nqus dej, thiab yuav tsis ua rau cov khoom siv puas tsuaj. Nws yog siv dav hauv cov tshuab cua compressor, cov tshuab ziab khaub ncaws thiab lwm yam khoom siv. Cov lus qhia dav dav yog 3-5mm 4-6mm.

Kev txhawb nqa alumina: feem ntau siv cov qauv loj heev thiab thaj chaw tshwj xeeb ntawm cov pob alumina ua haujlwm, thiab siv lub zog van der Waals los nqus cov tshuaj catalyst xav tau rau hauv cov qauv ntim ntawm cov pob alumina ua haujlwm, yog li cov pob alumina ua haujlwm tau impregnated hauv cov txheej txheem tshwj xeeb. Nws muaj tib lub luag haujlwm li cov tshuaj catalyst. Ntau yam catalysts tuaj yeem siv, xws li: cov tshuaj potassium permanganate, cov tshuaj organic, cov hlau tsis tshua muaj, cov hlau muaj nqis thiab lwm yam catalysts sib txawv, cov lus qhia dav dav yog 2-3mm.3-5mm.

Tus neeg sawv cev tshem tawm alumina fluoride: Nws feem ntau siv cov qhov hws loj thiab thaj chaw loj ntawm cov pob alumina ua kom muaj zog. Nws muaj peev xwm nqus tau fluoride thiab arsenide hauv cov tshuaj zoo. Nws tsis muaj tshuaj lom thiab tsis ua rau muaj kev phom sij thiab tsis cuam tshuam rau kev haus dej. Siv rau hauv cov dej hauv av thiab cov dej haus defluoridation, qhov loj me feem ntau yog 2-3 hli.
