Thandizo la A-aluminium chothandizira

Kufotokozera Kwachidule:

α-Al2O3 ndi zinthu zaporous, zomwe nthawi zambiri zimagwiritsidwa ntchito pothandizira zopangira, adsorbents, zipangizo zolekanitsa gasi, etc. α-Al2O3 ndi gawo lokhazikika la alumina yonse ndipo nthawi zambiri limagwiritsidwa ntchito kuthandizira zigawo zogwira ntchito zomwe zimakhala ndi chiwerengero chachikulu cha ntchito. .Kukula kwa pore kwa chonyamulira chothandizira cha α-Al2O3 ndikokulirapo kuposa njira yaulere ya maselo, ndipo kugawa kuli yunifolomu, kotero vuto la kufalikira kwamkati komwe kumachitika chifukwa cha kukula kwa pore mu dongosolo lothandizira litha kuthetsedwa bwino, komanso kuyatsa makutidwe ndi okosijeni. mbali zimachitikira akhoza kuchepetsedwa mu ndondomeko ndi cholinga kusankha makutidwe ndi okosijeni.Mwachitsanzo, chothandizira siliva chomwe chimagwiritsidwa ntchito popanga ethylene oxidation ku ethylene oxide chimagwiritsa ntchito α-Al2O3 ngati chonyamulira.Nthawi zambiri amagwiritsidwa ntchito pothandizira kutentha kwambiri komanso kuwongolera kufalikira kwakunja.
