Mkpọ molekụla 3A

Mkpọchi molekul 3A bụ aluminate alkali metal, mgbe ụfọdụ a na-akpọkwa ya mkpọchi molekul zeolite 3A.

Aha Bekee: 3A Molecular Sieve
Oke silica / aluminom: SiO2/Al2O3≈2
Nha oghere dị irè: ihe dị ka 3A (1A = 0.1nm)

Ụkpụrụ ọrụ nke sieve molekul metụtara nha oghere nke sieve molekul, n'otu n'otu 0.3nm/0.4nm/0.5nm, ha nwere ike itinye molekul gas nke dayameta molekul ha pere mpe karịa nha oghere ahụ, na ka ibu nke oghere ahụ, otú ahụ ka ikike adsorption si dịkwuo ukwuu. Nha oghere ahụ dị iche, ihe ndị a kpochara dịkwa iche. N'ụzọ dị mfe, sieve molekul 3a nwere ike itinye naanị molekul n'okpuru 0.3nm.

Mkpọchi molekul 3A nwere oghere dị nha 3A, nke a na-ejikarị eme ihe iji mịnye mmiri, ọ naghịkwa amịnye molekul ọ bụla nwere dayameta karịrị 3A. Dịka njirimara nke ojiji ụlọ ọrụ mmepụta ihe si dị, mkpọchi molekul nwere ọsọ mkpọchi ngwa ngwa, oge mmeghari ohuru, ike ịpịpịa na ikike mgbochi mmetọ, nke na-eme ka arụmọrụ ojiji nke mkpọchi molekul dịkwuo mma ma na-agbatị ndụ ọrụ nke mkpọchi molekul. Ọ bụ ihe dị mkpa maka mkpọchi miri emi, nchacha na polymerization nke usoro gas-mmiri mmiri na ụlọ ọrụ mmanụ ala na kemịkalụ.
