3A molekụla sieve

3A molecular sieve bụ alkali metal aluminate, mgbe ụfọdụ a na-akpọkwa ya 3A zeolite molecular sieve.

Aha Bekee: 3A Molecular Sieve
Silica / aluminum ratio: SiO2 / Al2O3≈2
Ogo pore dị irè: ihe dịka 3A (1A = 0.1nm)

Ụkpụrụ ọrụ nke sieve molecular bụ nke metụtara pore size nke molecular sieve, karị 0.3nm / 0.4nm / 0.5nm, ha nwere ike adsorb gas ụmụ irighiri ihe ndị dayameta molekụla dị obere karịa pore size, na ibu pore size, na ibu ikike adsorption. Ogo nke oghere ahụ dị iche, na ihe ndị a kpochara dị iche iche. N'okwu dị mfe, sieve molekụla 3a nwere ike ịgbasa ụmụ irighiri ihe n'okpuru 0.3nm.

3A molekụla sieve nwere oghere nke 3A, nke a na-ejikarị eme ka mmiri na-ekpo ọkụ, ọ dịghịkwa anabata molekul ọ bụla nwere dayameta karịrị 3A. Dị ka e ji mara nke ngwa ụlọ ọrụ mmepụta ihe, molekụla sieve nwere ngwa ngwa adsorption ọsọ, oge mmụgharị, na-etipịa ike na mgbochi mmetọ ike, nke na-eme ka ojiji nke molekụla sieve na-agbatị ndụ ọrụ nke molekul sieve. Ọ bụ ihe mgbasa ozi dị mkpa maka ihicha miri emi, nchacha na polymerization nke gas-mmiri mmiri na mmanụ ala na ụlọ ọrụ kemịkalụ.
