1, Lub tswvyim ntawm molecular sieve
MolecularSieve yog ib hom silico-aluminate multi-microporous siv lead ua, uas muaj cov yam ntxwv ntawm cov pore loj, siab tshwj xeeb thaj chaw, zoo thermal stability, muaj zog adsorption cov cuab yeej, loj sab hauv deg cheeb tsam thiab siab zog.
MolecularSieve vim nws cov kev siv sib txawv, thiaj li muab faib ua 3A, 4A, 5A, 13X, 13X cua sib cais tshwj xeeb MolecularSieve, hollow iav MolecularSieve, MolecularSieve activated hmoov, carbon MolecularSieve thiab hais txog.
2, Qhov zoo ntawm molecular sieves
Adsorption yog xaiv raws li qhov loj thiab cov duab ntawm cov molecules, uas yog, tsuas yog cov molecules uas me dua qhov pore loj ntawm MolecularSieve yog adsorbed. Rau me polarity zoo thiab unsaturated zoo, nrog kev xaiv haum ntawm kev txhaj tshuaj zog,
Qhov ntau dua qhov polarity thiab siab dua qhov unsaturation, qhov muaj zog dua qhov kev xaiv haum. Nws muaj zog nqus dej. Txawm tias nyob rau hauv qhov kub thiab txias, airspeeds loj dua thiab cov ntsiab lus dej qis, tseem muaj peev xwm nqus dej txaus.
3, Hollow iav:
Nyob rau hauv cov iav insulating nyob rau hauv kev ua lag luam tam sim no, cov desiccant siv nyob rau hauv qee cov khoom tsis yog 3A MolecularSieve los ua cov desiccant, qee cov tuam ntxhab yuav siv 4A MolecularSieve, thiab txawm siv chav B desiccant ua cov khoom siv hauv cov iav insulating.
Qhov no yuav ua rau lub neej kev pab cuam ntawm lub iav insulating yuav raug txo.
Txawm hais tias 4A molecular sieve muaj lub peev xwm adsorption muaj zog rau cov dej, nws kuj muaj peev xwm adsorption muaj zog rau nitrogen thiab lwm yam inert gases hauv huab cua, thiab nws yuav nce thiab txo nrog qhov kub thiab txias.
Cov roj hauv cov iav insulating yog adsorbed thiab tso tawm. Nrog rau qhov kev hloov ntawm qhov kub thiab txias sib txawv ntawm nruab hnub thiab hmo ntuj los yog kev hloov ntawm lub caij, lub iav insulating yog yooj yim distorted thiab tawg vim expansion thiab contraction, ua rau muaj kev nyab xeeb xwm txheej.
Yog li ntawd, hauv kev tsim cov iav insulating, nws yog nruj me ntsis txwv tsis pub siv lwm yam MolecularSieve uas tsis yog 3A li insulating iav desiccant.
