Molecular sieve yog ib qho khoom adsorbent uas tuaj yeem cais cov molecules ntawm ntau qhov sib txawv. Nws yog SiO2, Al203 raws li crystalline aluminium silicate nrog lub ntsiab tivthaiv. Muaj ntau qhov ntawm qhov loj me hauv nws cov siv lead ua, thiab muaj ntau qhov ntawm tib txoj kab uas hla ntawm lawv. Nws tuaj yeem adsorb cov molecules me dua qhov pore txoj kab uas hla mus rau sab hauv ntawm lub qhov, thiab tsis suav cov molecules loj dua lub aperture rau sab nraud, ua si lub luag haujlwm ntawm sieve.
Molecular sieve muaj zog nqus dej noo, thiab yuav luag tag nrho cov kuab tshuaj tuaj yeem siv los ziab nws, yog li nws tau siv dav hauv kev sim thiab kev lag luam. Molecular sieve adsorption txoj kev yog ib txoj kev dehydration nrog tsawg zog noj thiab high efficiency, cov txheej txheem yog yooj yim, ntau haum rau lub sib sib zog nqus lub cev qhuav dej ntawm cov kua thiab roj, siv qhov luaj li cas ntawm molecular sieve aperture xaiv adsorption ntawm dej, thiaj li. ua tiav kev sib cais.
Lub thermal stability ntawm molecular sieve yog qhov zoo, uas tuaj yeem tiv taus qhov kub siab ntawm 600C ~ 700C, thiab qhov kub thiab txias yuav tsum tsis pub tshaj 600C, txwv tsis pub cuam tshuam rau kev ua haujlwm ntawm molecular sieve, thiab tuaj yeem khiav tawm (tsis muaj thermal regeneration). Molecular sieve tsis soluble nyob rau hauv dej, tab sis yaj nyob rau hauv muaj zog acids thiab alkali, yog li nws yuav siv tau nyob rau hauv nruab nrab ntawm pH5 ~ 11. Molecular sieve yog ib qho yooj yim rau nqus dej, yuav tsum tau kaw cia, siv yuav tsum xyuas seb cov dej cov ntsiab lus siab tshaj tus qauv, cia rau lub sij hawm ntev noo noo nqus, yuav tsum tau siv tom qab siv, nws cov kev ua tau zoo tsis hloov. Molecular sieve muaj cov yam ntxwv ntawm ceev ceev adsorption ceev, ntau lub sij hawm tsim dua tshiab, siab crushing thiab hnav tsis kam, muaj zog ua paug tsis kam, siab siv efficiency, ntev kev pab cuam lub neej, thiab lwm yam.
