Kev thov muaj txiaj ntsig ntawm3a molecular si cib qhib hmoov nplej
Hauv kev tsim cov polyurethane nplaum nplaum, tshem tawm ntawm ya raws thiab huab cua npuas yog qhov tseem ceeb los ua kom cov khoom lag luam. Ya ya raws li ortocyanates los tsim cov pa roj carbon dioxide, uas tuaj yeem ua rau pinholes thiab npuas nyob rau hauv txheej. Lub caij no, mechanically qhia npuas thaum sib xyaw cuam tshuam rau cov khoom siv nyiaj txiag thiab lub zog ua kom muaj zog.
3A molecular sirib tshuab antic antated: ua lub cev tsis zoo, txuag hluav taws xob
3A molecular siric milling hmoov yog ib qho tshwj xeeb, zoo-particle cov khoom siv rau kev tshem tawm noo noo. Nrog nws qhov tshwj xeeb pore loj ntawm 3 Å, nws xaiv adsorbs dej lwg me me (kwv yees lwmyam molecules kom dhau los, tswj xyuas kev ncaj ncees ntawm cov polyurethane system. Raws li lub cev adsorption-hom defoaming tus neeg sawv cev, nws ua rau pom kev ua tau zoo:
hal noo kev tshem tawm efficiency: ntawm 35% txheeb ze cov av noo, cov dej paug dej zoo li qub tau tuaj yeem ncav cuag ntau dua 23 wt%.
Cov qauv tsim qauv: Chemxin 3A ua haujlwm molecular sab cib hmoov ntau yam ntxwv ntawm qhov loj me {. 45 g \/ mL, muab kev cuam tshuam zoo tshaj plaws thiab tiv thaiv cov khoom.
superior sib xyaw: Qhov chaw hloov kho co tshuaj huab cua txhim kho polyurethane nrog polyurethane latrix rau ruaj khov, ntev kev tshem tawm ntev
Zoo kawg li kev ua tau zoo hauv kev siv
Hauv cov ntawv thov xws li Polyurethane Potting tebchaw, ntxiv 3% -5% ntawm 3a molecular si cib qhib tau txhim kho lub system zoo:
Moisture cov ntsiab lus txo los ntawm {{0}}}}. 15% rau hauv qab 0.02%
FOAM qhov siab txo los ntawm 75%
LOUNTY TXHUA YAM UA HAUJLWM pom nyob hauv 48 teev
Cov khoom kawg tuaj yeem ua tiav npuas qhov loj me dua hauv qab 5 0}} μm thiab cov dej noo cov ntsiab lus hauv qab no xws li encapsive interiors thiab tshuab hluav taws xob.
Outlook: Txhim Kho Polyurethane Kev Ua Haujlwm los ntawm thev naus laus zis thev naus laus zis
Nrog rau kev nce qib tsis tu ncua hauv kev hloov pauv saum npoo av thiab kev lag luam tawm tshiab hauv kev siv hluav taws xob, txhim kho cov nqi zog polyurethane, thiab txhim kho cov khoom muaj kev ntseeg tau.
