Isisefo se-molecular

I-molecular sieve iyi-adsorbent eqinile engahlukanisa ama-molecule anobukhulu obuhlukahlukene. I-SiO2, i-Al203 njenge-crystalline aluminium silicate enengxenye eyinhloko. Kunezimbobo eziningi zobukhulu obuthile ku-crystal yayo, futhi kunezimbobo eziningi ezinobubanzi obufanayo phakathi kwazo. Ingakwazi ukukhangisa ama-molecule amancane kunobubanzi bembotshana ukuya ngaphakathi kwembobo, futhi ikhiphe ama-molecule amakhulu kunembobo eya ngaphandle, idlala indima yesisefo.

Isisefo samamolekyuli sinamandla okumunca umswakama oqinile, futhi cishe zonke izincibilikisi zingasetshenziswa ukuze zomiswe, ngakho sisetshenziswa kakhulu elabhorethri nasembonini. I-Molecular sieve adsorption method iyindlela yokukhipha amanzi emzimbeni esebenzisa amandla aphansi kanye nokusebenza kahle okuphezulu, inqubo ilula, ifaneleka kakhudlwana ukuphelelwa amanzi emzimbeni okujulile koketshezi negesi, ukusetshenziswa kosayizi we-molecular sieve aperture adsorption ekhethiwe yamanzi, ukuze finyelela ukwehlukana.

Ukuzinza okushisayo kwe-sieve yamangqamuzana kuhle, okungamelana nokushisa okufushane okuphezulu kwe-600C ~ 700C, futhi izinga lokushisa lokuvuselela akufanele lidlule i-600C, ngaphandle kwalokho kuthinte umsebenzi we-molecular sieve, futhi ingakhishwa (akukho ukuvuselelwa okushisayo). Isisefo samangqamuzana asincibiliki emanzini, kodwa sincibilika kuma-asidi aqinile ne-alkali, ngakho singasetshenziswa phakathi nendawo ye-pH5~11. Isihlungo samangqamuzana kulula ukumunca amanzi, kufanele sivalwe isitoreji, ukusetshenziswa kufanele kuhlole ukuthi okuqukethwe kwamanzi kudlula izinga, isitoreji isikhathi eside ukumuncwa umswakama, kufanele kusetshenziswe ngemva kokusetshenziswa, ukusebenza kwawo kungashintshiwe. Isisefo samangqamuzana sinezici zesivinini sokukhangisa esisheshayo, izikhathi eziningi zokuvuselela, ukuchotshozwa okuphezulu nokumelana nokugqoka, ukumelana nokungcola okuqinile, ukusebenza kahle kakhulu kokusetshenziswa, impilo ende yesevisi, njll., okuyi-desiccant ethandwayo yegesi nesigaba soketshezi okomisa okujulile.
