Cov pa roj carbon molecular sieve (CMS) yog cov khoom siv adsorption siab heev uas ua ke cov khoom ntawm cov pa roj carbon activated thiab zeolites. Tsim nyob rau hauv 1970s, CMS yog cov khoom siv tsis yog-polar carbon-raws li nrog rau thaj chaw siab sab hauv thiab cov qauv pore tshwj xeeb. Cov pores no muaj qhov loj me ntawm 0.28 txog 0.38 nanometers, tso cai rau kev sib cais ntawm cov pa roj zoo raws li lawv qhov loj me me thiab qhov sib txawv.
Molecular sieves yog dav siv rau kev sib sib zog nqus ziab ntawm cov pa roj thiab kua xws li cua, nkev roj, alkanes, tub yees thiab cov kuab tshuaj; purification ntawm nitrogen; tshem tawm nyob rau hauv cov xim, dyeing thiab txheej industries; thiab hluav taws xob zoo li qub hauv kev ntim tshuaj, cov khoom siv hluav taws xob thiab cov tshuaj perishable. Nws tseem tuaj yeem tshawb pom cov pa roj carbon monoxide siab, sib txuas cov khoom nqus adsorption kinetics thiab lub cev ruaj khov kom ntseeg tau lub neej ntev dua. Tshem tawm cov dej molecular tsawg, cov ntsiab lus kub kub, hydrogen thiab mercaptans. Tsim tshwj xeeb rau kev tshem tawm hauv cov tshuab cua hauv tsheb, suav nrog kev tshem tawm cov dej noo ntawm cov cua txias thiab cua nres tshuab. Los ntawm kev ntim khoom noj mus rau cov kws tshuaj, peb cov khoom siv molecular sieve desiccants tuaj yeem siv los khaws cov khoom. Peb cov desiccants muaj peev xwm adsorption zoo, pab tiv thaiv kev puas tsuaj los ntawm ya raws, pwm thiab lwm yam dej noo, thaum lawv muaj peev xwm ua kom pom huab cua zoo heev pab tiv thaiv cov pa oxygen nkag mus rau hauv lub ntim.
FAQ
Q: Koj puas tuaj yeem muab cov qauv dawb?
A: Cov qauv pub dawb tuaj yeem muab tau, tab sis tus nqi thauj khoom yog nyob ntawm koj tus nqi. Tus nqi yuav raug xa rov qab rau koj lossis txiav tawm ntawm koj qhov kev txiav txim.
Q: Lub sijhawm xa khoom ntev npaum li cas ntawm koj cov khoom?
A: Rau cov khoom lag luam zoo tib yam, peb feem ntau muaj cov khoom lag luam. Cov khoom tshwj xeeb yuav tsum tau sib tham nrog cov neeg siv khoom.
Q: Koj qhov kev pab cuam tom qab muag zoo li cas?
A: Yog tias muaj teeb meem, peb yuav sim peb qhov zoo tshaj plaws los nrhiav kev daws teeb meem thiab muab cov lus pom zoo rau koj, thiab peb yuav taug qab tag nrho cov txheej txheem txij thaum peb tau txais kev txiav txim mus rau thaum koj tau txais cov khoom.
Q: Yuav ua li cas txog lub ntim?
A: Feem ntau peb siv cov ntim zoo tib yam, xws li hnab yas, hnab ntawv kraft. Yog tias cov neeg siv khoom xav tau, peb yuav ua tau raws li cov neeg siv khoom xav tau.
