Polyurethane (coatings, sealants, adhesives)
Moisture nyob rau hauv lub PU system reacts nrog isocyanate, tsis muaj teeb meem nyob rau hauv ib qho khoom los yog ob lub ntsiab polyurethane cov khoom, uas tsim amine thiab carbon dioxide, amine txuas ntxiv mus nrog isocyanate, yog li ntawd nws noj kom tso pa carbon dioxide nyob rau tib lub sij hawm, ua npuas nyob rau saum npoo ntawm cov xim zaj duab xis, ua rau deterioration lossis txawm tias qhov ua tau zoo ntawm cov xim zaj duab xis tsis ua haujlwm.
2% ~ 5% ntawm molecular sieve (hmoov) nyob rau hauv lub system yog txaus los tshem tawm cov seem uas seem nyob rau hauv PU system, tab sis nws yog thaum kawg nyob ntawm cov dej noo nyob rau hauv lub system.
Anti-corrosive txheej
Nyob rau hauv epoxy zinc-nplua nuj primer, ib tug kab ntawm cov dej yuav tsim ib tug zoo tshuaj tiv thaiv nrog zinc hmoov, tsim hydrogen, ua rau kom lub siab nyob rau hauv lub chim, txo lub neej kev pab cuam ntawm primer, ua rau lub nruj, hnav tsis kam thiab hardness. ntawm txheej zaj duab xis.Molecular sieve (hmoov) raws li cov dej nqus dej desiccant, uas yog tag nrho lub cev adsorption, yuav tshem tawm cov dej thiab tsis muaj qhov cuam tshuam nrog lub substrate.Yog li molecular sieve muaj kev nyab xeeb thiab yooj yim rau kev tiv thaiv corrosive txheej txheej.
Hlau hmoov txheej
Cov tshuaj tiv thaiv zoo sib xws tuaj yeem tshwm sim hauv cov hmoov hlau hmoov txheej, xws li hauv cov hmoov txhuas hmoov txheej.
