1.6 ~ 2.5mm Zeolite molecular sieve 3a 4a 5a tus qauv, tshuaj lom neeg, thiab siv
Adsorption kev ua tau zoo
Kev nqus ntawm zeolite molecular sieve yog txheej txheem hloov lub cev. Qhov laj thawj tseem ceeb rau kev nqus tau yog ib yam ntawm "lub zog saum npoo av" tsim los ntawm kev nqus lub cev ua rau lub cev tawv. Thaum cov dej ntws hla, qee cov lwg me me hauv cov kua sib tsoo nrog cov nplaim dej ntawm cov dej tsis haum vim ua tsis tau zoo, ua rau muaj cov ntsiab lus molecular ntawm qhov chaw. Txo cov naj npawb ntawm cov lwg me me hauv cov kua kom ua tiav lub hom phiaj ntawm kev sib cais thiab tshem tawm. Txij li thaum tsis muaj tshuaj hloov pauv hauv kev nqus, tsuav yog peb sim tshem tawm cov lwg me me tsom mus rau saum npoo, zeolite molecular sieve yuav muaj peev xwm nqus tau dua. Cov txheej txheem no yog txheej txheem thim rov qab ntawm kev nqus, hu ua kev tshuaj xyuas lossis rov tsim dua tshiab. Txij li zeolite molecular sieve muaj qhov sib xws qhov loj me me, tsuas yog thaum cov txheej txheem cov txheej txheem molecular me dua li zeolite molecular sieve tuaj yeem nkag tau yooj yim sab hauv ntawm cov kab noj hniav siv lead ua thiab raug adsorbed. Yog li ntawd, zeolite molecular sieve zoo li lub lauj kaub rau cov roj thiab cov kua ua kua, thiab nws tau txiav txim siab tias yuav tsum tau nqus los yog tsis raws li qhov loj ntawm cov molecule. . Txij li zeolite molecular sieve muaj qhov sib zog muaj zog hauv cov kab noj hniav crystalline, nws tuaj yeem muaj qhov cuam tshuam zoo ntawm qhov ze ntawm zeolite molecular sieve nrog cov lwg me me uas muaj cov pab pawg ncov qaumteb, lossis los ntawm kev ua kom lub polarization ntawm polarizable molecules los ua kom muaj zog adsorption. Hom polar lossis polarized molecules yooj yim tau yooj yim kom raug adsorbed los ntawm polar zeolite molecular sieve, uas qhia txog lwm qhov kev xaiv adsorption ntawm zeolite molecular sieve.
Ion pauv kev ua tau zoo
Feem ntau hais lus, kev sib pauv ion hais txog kev sib pauv cov nyiaj them poob haujlwm sab nraum lub hauv paus ntawm zeolite molecular sieve. Kev them nyiaj ions sab nraum lub hauv paus ntawm zeolite molecular sieve feem ntau yog cov protons thiab alkali hlau lossis alkaline earth metals, uas tau yooj yim ion-pauv mus rau ntau yam valence hlau ion-hom zeolite molecular sieves hauv cov kua ntsev ntawm cov ntsev ntsev. Ions yooj yim dua rau kev tsiv chaw nyob hauv qee qhov xwm txheej, xws li cov kua dej los yog qhov kub siab dua.
Hauv cov kua dej, vim qhov sib txawv ion xaiv ntawm zeolite molecular sieves, cov khoom sib pauv ion sib txawv tuaj yeem nthuav tawm. Hydrothermal ion pauv cov tshuaj tiv thaiv ntawm cov hlau cations thiab zeolite molecular sieves yog txheej txheem pub dawb. Tus nqi sib kis txwv kev sib pauv cov tshuaj tiv thaiv.
Kev ua tau zoo catalytic
Zeolite molecular sieves muaj qhov tshwj xeeb niaj hnub siv ua qauv, txhua tus uas muaj cov qauv pore ntawm qee qhov loj me thiab cov duab, thiab muaj thaj tsam loj tshwj xeeb. Feem ntau zeolite molecular sieves muaj cov chaw muaj zog acid nyob rau saum npoo, thiab muaj lub zog Coulomb teb nyob rau hauv qhov siv lead ua pores rau polarization. Cov yam ntxwv no ua rau nws yog lub luag haujlwm zoo tshaj plaws. Heterogeneous catalytic tshua yog nqa tawm ntawm cov khoom catalysts, thiab cov haujlwm catalytic cuam tshuam nrog qhov loj ntawm cov pores siv lead ua ntawm cov catalyst. Thaum zeolite molecular sieve tau siv los ua catalyst lossis catalyst carrier, kev nce qib ntawm cov tshuaj tiv thaiv catalytic yog tswj los ntawm qhov pore loj ntawm zeolite molecular sieve. Qhov loj me thiab cov duab ntawm cov pores thiab cov pores tuaj yeem ua lub luag haujlwm xaiv hauv cov tshuaj tiv thaiv catalytic. Raws li cov xwm txheej tshwm sim, zeolite molecular sieves ua lub luag haujlwm tseem ceeb hauv cov tshuaj tiv thaiv kev taw qhia thiab nthuav tawm cov duab-xaiv xaiv catalytic kev ua tau zoo. Qhov kev ua tau zoo no ua rau zeolite molecular sieves cov khoom siv catalytic tshiab nrog lub zog loj.
