Chithandizo cha alpha alumina chothandizira

Kufotokozera Kwachidule:

α-Al2O3 ndi zinthu zaporous, zomwe nthawi zambiri zimagwiritsidwa ntchito pothandizira othandizira, adsorbents, zipangizo zolekanitsa gasi, etc. α-Al2O3 ndi gawo lokhazikika kwambiri la alumina yonse ndipo nthawi zambiri amagwiritsidwa ntchito kuthandizira zigawo zogwira ntchito zomwe zimakhala ndi chiŵerengero chachikulu cha ntchito. The pore kukula kwa chonyamulira α-Al2O3 chothandizira ndi lalikulu kwambiri kuposa maselo ufulu njira, ndi kugawa ndi yunifolomu, kotero vuto mayamwidwe mkati chifukwa yaing'ono pore kukula mu dongosolo chothandizira anachita akhoza bwino kuthetsedwa, ndi kuya makutidwe ndi okosijeni mbali zimachitikira akhoza kuchepetsedwa mu ndondomeko ndi cholinga chosankha 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.
