Kumvetsetsa Ma Desiccants: Udindo wa Alumina Woyambitsa

Desiccants ndi zinthu zomwe zimatenga chinyezi kuchokera ku chilengedwe, zomwe zimawapangitsa kukhala ofunikira m'mafakitale osiyanasiyana kuti asunge kukhulupirika kwa zinthu ndi zida. Pakati pa ma desiccants ambiri omwe alipo, alumina yoyendetsedwa imadziwika chifukwa cha mawonekedwe ake apadera komanso kusinthasintha.

Aluminium activated ndi mtundu waporous kwambiri wa aluminium oxide, wopangidwa ndi kuchitira aluminium hydroxide ndi kutentha. Izi zimakulitsa malo ake pamwamba ndi mphamvu zotsatsa, zomwe zimapangitsa kukhala desiccant yothandiza. Ndi malo opitilira 300 m²/g, aluminiyamu yoyendetsedwa imatha kuyamwa madzi ochulukirapo, ndikupangitsa kuti ikhale yoyenera kugwiritsa ntchito komwe kuwongolera chinyezi ndikofunikira.

Chimodzi mwazofunikira kwambiri za aluminiyamu activated ndi kuyanika mpweya ndi zakumwa. M'mafakitale, nthawi zambiri amagwiritsidwa ntchito kuchotsa chinyezi kuchokera ku mpweya woponderezedwa ndi gasi wachilengedwe, kuteteza dzimbiri ndikuwonetsetsa kuti zida zikuyenda bwino. Kuphatikiza apo, aluminiyamu yoyendetsedwa imagwiritsidwa ntchito popanga mankhwala oyeretsedwa kwambiri ndi mankhwala, pomwe ngakhale kuchuluka kwa chinyezi kumatha kusokoneza mtundu wazinthu.

Aluminium activated imagwiranso ntchito yofunika kwambiri pakuyeretsa madzi. Ndiwothandiza pochotsa fluoride ndi arsenic m'madzi akumwa, ndikupangitsa kuti ikhale gawo lofunikira pamakina oyeretsa madzi. Kuthekera kwake kutsatsa zonyansa ndikusungabe kutsika kwamadzi kumatsimikizira kuti madzi oyeretsedwa amakhalabe otetezeka kuti amwe.

Kuphatikiza apo, aluminiyamu yoyendetsedwa imatha kugwiritsidwanso ntchito. Ikhoza kubwezeretsedwanso ndi kutentha, kulola kumasula chinyezi chokhazikika ndikugwiritsidwa ntchito mobwerezabwereza. Khalidweli silimangopangitsa kuti likhale lopanda mtengo komanso lothandizana ndi chilengedwe, chifukwa limachepetsa zinyalala zomwe zimagwiritsidwa ntchito ndi desiccants imodzi yokha.

Pomaliza, alumina yoyendetsedwa ndi desiccant yamphamvu yokhala ndi ntchito zosiyanasiyana m'mafakitale osiyanasiyana. Kuthekera kwake kotengera chinyezi, kuphatikizidwa ndi kugwiritsiridwanso ntchito kwake, kumapangitsa kukhala chida chofunikira kwambiri posunga zinthu zabwino komanso chitetezo m'malo osamva chinyezi.
