3A Molecular Sieves Activated Powder Rau Gassing Thiab Bubbling Control
3A activation hmoovyog ib hom molecular sieve hmoov raws li A-type crystal nrog potassium daim ntawv ntawm cov qauv, nws muaj peev xwm xaiv adsorb sib txawv molecular tshuaj raws li molecular loj thiab polarity, nws muaj peev xwm adsorb tag nrho cov molecules nrog zoo txoj kab uas hla tsawg dua 0.3nm (xws li dej molecules). Qhov sib ntxiv ntawm cov hmoov ua kom muaj nuj nqis hauv lub cev tuaj yeem tshem tawm cov dej los ntawm PU system, thiab nws tsis adsorb cov kuab tshuaj, resins lossis pigments, zam qhov tsim ntawm huab cua npuas thiab ncua kev pab cuam lub neej ntawm cov khoom, yog li cov hmoov ua kom muaj zog yog qhov zoo heev. Dehumidifier rau PU coatings, nplaum thiab sealants.3A molecular sieves activated hmoovtuaj yeem siv rau gassing thiab bubbling tswj nyob rau hauv ob feem polyurethane adhesives.

Molecular sieve activation hmoov plays lub luag haujlwm tseem ceeb hauv kev tsim cov polysulfide sealant. Nws yog ib qho zoo heev desiccant uas pab absorbing noo noo los ntawm raw cov ntaub ntawv siv nyob rau hauv cov txheej txheem ntau lawm.
Polysulfide sealant feem ntau yog siv rau hauv kev tsim kho thiab paub txog nws qhov zoo heev adhesion, tshuaj tiv thaiv, thiab kav ntev. Txawm li cas los xij, yog tias muaj dej noo nyob rau hauv nws qhov kev tsim khoom, nws tuaj yeem ua rau txo qis hauv qhov zoo ntawm cov sealant, cuam tshuam rau nws cov kev ua tau zoo.
Txhawm rau tiv thaiv qhov no tshwm sim, molecular sieve activation hmoov yog ntxiv rau cov khoom siv raw. Nws ua haujlwm los ntawm kev nqus cov dej noo tam sim no hauv cov ntaub ntawv ua ntej lawv ua tiav, kom ntseeg tau tias cov khoom kawg yog qhov zoo tshaj plaws.
Siv molecular sieve activation hmoov yog ib qho kev daws teeb meem zoo rau cov tuam txhab vim nws ua kom cov kav ntev thiab ua haujlwm ntawm polysulfide sealant, ua kom nws lub neej ntev thiab tiv thaiv tsis ua haujlwm ntxov.
