Zeolite Properties thiab Stability
Jan 01, 2022
Tsis muaj decomposition yog siv thiab khaws cia raws li cov kev qhia tshwj xeeb, tsis paub txog kev phom sij, tsis txhob oxidizing tus neeg sawv cev. Soluble nyob rau hauv muaj zog alkali. Yog ib lub siab silica zeolite. Nws muaj cov qauv pore tshwj xeeb, kev ua haujlwm siab catalytic, thermal stability thiab acid tsis kam.
Zeolite yog ib lo lus dav dav rau cov zaub mov hauv tsev neeg zeolite, uas yog cov dej uas muaj alkali lossis alkaline ntiaj teb hlau aluminosilicate ntxhia. Ntau tshaj 40 hom zeolites ntuj tau pom thoob plaws ntiaj teb, cov uas muaj ntau tshaj plaws yog clinoptilolite, mordenite, chabazite, erionite, zeolite, heuerite, hazelite, pyroxene thiab analcite. Clinoptilolite thiab mordenite tau siv ntau heev. Cov pob zeb zeolite muaj nyob hauv cov tshuab siv lead ua sib txawv, thiab cov muaju feem ntau yog fibrous, plaub hau, columnar, thiab ob peb yog phaj lossis luv columnar.
Zeolite muaj ion pauv, adsorption sib cais, catalysis, stability, tshuaj reactivity, reversible dehydration, hluav taws xob conductivity, thiab lwm yam. nws kuj yog tsim nyob rau hauv pyroclastic sedimentary pob zeb thiab kub caij nplooj ntoos hlav deposits.
