Khoom Description
Daim ntawv thov ntawm molecularsieve hauv txheej yog feem ntau xav txog hauv cov hauv qab no:
1, Tshem tawm cov dej noo thiab impurities
Molecular sieve muaj cov qauv microporous zoo, uas tuaj yeem tshem tawm cov dej thiab impurities hauv txheej los ntawm adsorption. Cov dej noo thiab impurities no, yog tias tso rau hauv cov xim, tuaj yeem cuam tshuam cov txheej txheem kev ua haujlwm, hardness, gloss, hnav tsis kam thiab lwm yam ntawm kev ua haujlwm. Yog li ntawd, qhov sib ntxiv ntawm nws tuaj yeem txhim kho qhov zoo thiab kev ua haujlwm ntawm txheej txheej.
2, Txhim kho lub cev muaj zog ntawm cov txheej txheem
Los ntawm kev tshem tawm cov dej noo thiab impurities los ntawm cov xim, molecular sieve kuj pab ua kom lub cev zoo ntawm cov xim. Piv txwv li, nws tuaj yeem txhim kho cov txheej txheem kev ua haujlwm, huab cua tsis kam, dej tsis kam, tiv thaiv corrosion thiab kev laus ntawm cov txheej txheem. Cov kev txhim kho kev ua tau zoo no ua rau cov xim kom muaj kev ruaj ntseg zoo dua thiab kav ntev thaum siv sijhawm ntev -.
3, Txo qhov tsim ntawm npuas
Hauv qee hom txheej txheej xws li polyurea waterproof coatings, molecular sieve kuj plays lub luag hauj lwm hauv kev txo cov npuas. Lub isocyanate, lub ntsiab tseem ceeb ntawm polyurea waterproof txheej, reacts nrog dej los tsim cov pa roj carbon dioxide, uas ua rau tsim cov npuas. Nws tuaj yeem nqus dej hauv cov txheej txheej, yog li txo cov tshuaj tiv thaiv ntawm isocyanate thiab dej thiab tsis txhob tsim cov npuas. Tsis tas li ntawd, cov tshuaj tiv thaiv yog exothermic cov tshuaj tiv thaiv, yuav ua rau muaj cua sov ntau los ua kom cov npuas, qhov sib ntxiv ntawm nws tuaj yeem txo qhov xwm txheej no mus rau qee yam.
4, Txhim kho qhov sib xws thiab lub zog ntawm cov txheej txheem
Qhov sib ntxiv ntawm molecular sieve kuj tuaj yeem txhim kho qhov sib xws thiab lub zog ntawm txheej. Nws muaj zog adsorption muaj peev xwm ua rau muaj pes tsawg leeg nyob rau hauv lub txheej ntau tusyees faib, yog li txhim kho tag nrho cov kev ua tau zoo ntawm txheej. Nyob rau tib lub sijhawm, Nws kuj tuaj yeem cuam tshuam nrog qee cov khoom hauv cov txheej txheem txhawm rau txhim kho lub zog ntawm txheej txheej.
5, Daim ntawv thov piv txwv
Hauv kev tsim cov txheej txheem ntawm polyurea waterproof txheej, molecular sieve feem ntau yog siv los ua ib qho ntxiv los txhim kho qhov zoo thiab ruaj khov ntawm txheej. Los ntawm kev ntxiv molecularsieve activated hmoov ua lub cev qhuav dej rau lub cev ua ntej cov tshuaj tiv thaiv ntawm isocyanate thiab polyurea resin, cov dej thiab impurities hauv lub cev tuaj yeem raug adsorbed, txhawm rau txhim kho qhov zoo thiab kev ua haujlwm ntawm txheej. Tsis tas li ntawd, qee qhov kev tshawb fawb kuj tau siv graphene hloov kho mesoporous molecularsieves hauv dej - nthuav dav cov khoom siv roj hmab sealing los txhim kho cov tshuaj lom neeg ruaj khov thiab ruaj khov ntawm cov khoom siv.
Yog li daim ntawv thov ntawm molecular sieve nyob rau hauv txheej muaj ntau yam kev cia siab thiab tseem ceeb tus nqi. Nws tuaj yeem tsis tsuas yog txhim kho qhov zoo thiab kev ua haujlwm ntawm cov xim, tab sis kuj ua kom zoo rau lub cev ntawm cov xim thiab txo cov npuas. Nrog kev nce qib ntawm kev siv thev naus laus zis thiab kev nthuav dav ntxiv ntawm daim ntawv thov kev lag luam, daim ntawv thov ntawm nws hauv cov txheej txheem yuav ua kom dav dua thiab hauv - qhov tob.
