3A isihlungi sama-molecule

Isihlungi sama-molecule se-3A siyi-alkali metal aluminate, ngezinye izikhathi sibizwa nangokuthi isihlungi sama-molecule se-3A zeolite.

Igama lesiNgisi: 3A Molecular Sieve
Isilinganiso se-silica / i-aluminium: i-SiO2/ i-Al2O3≈2
Usayizi wembobo osebenzayo: cishe u-3A (1A = 0.1nm)

Umgomo wokusebenza wesihlungi sama-molecule uhlobene kakhulu nosayizi wembobo yesihlungi sama-molecule, ngokulandelana okungu-0.3nm/0.4nm/0.5nm, angamunca ama-molecule egesi anobubanzi bama-molecule obuncane kunosayizi wembobo, futhi uma usayizi wembobo umkhulu, kulapho amandla okumunca abe makhulu khona. Usayizi womhubhe uhlukile, futhi izinto ezihlungiwe zihlukile. Ngamagama alula, isihlungi sama-molecule esingu-3a singamunca ama-molecule angaphansi kuka-0.3nm kuphela.

Isihlungi sama-molecule esingu-3A sinosayizi wembobo engu-3A, esetshenziswa kakhulu ukumunca amanzi, futhi asimunca noma yiliphi i-molecule enobubanzi obungaphezu kuka-3A. Ngokwezici zokusetshenziswa kwezimboni, isihlungi sama-molecule sinesivinini sokumunca esisheshayo, izikhathi zokuvuselelwa, amandla okuchoboza kanye nekhono lokulwa nokungcola, okuthuthukisa ukusebenza kahle kwesihlungi sama-molecule futhi kwandise impilo yenkonzo yesihlungi sama-molecule. Siyinto edingekayo yokumunca ukuze komiswe ngokujulile, kuhlungwe futhi kupholimeke isigaba segesi noketshezi embonini kaphethiloli kanye namakhemikhali.
