    Cov Lus Nug Feem Ntau

    Kuv tsim cov khoom siv polyurethane sealant uas kho tau dej ib feem. DMDE ua haujlwm li cas?

    DMDE yog ib qho catalyst latent; nws tsuas yog ua haujlwm thaum muaj dej noo, muab kev ruaj khov ntev (≥12 lub hlis).

    Kuv cov sealant tawv sai dhau, ua rau muaj cov kab nrib pleb. Yuav kho li cas?

    Txo DMDE rau 0.2–0.3 phr kom qeeb qhov kho ntawm qhov chaw, cia sijhawm txaus rau kev sib npaug.

    Puas siv tau DMDE rau hauv cov nplaum polyurethane kub-yaj (HMPUR)?

    Yog lawm, nws yog tus qauv kev lag luam rau HMPUR uas kho tau dej noo, muab cov viscosity ruaj khov ntawm 120 ° C thiab lub zog ntsuab sai.

    Tus nqi ntawm DMDE hauv ib txheej txheej hauv pem teb yog dab tsi?

    0.5–1.0 phr (raws li prepolymer) rau lub sijhawm tsis muaj tack ntawm 2–4 teev ntawm 50% RH.

    Kuv cov elastomer kho dej muaj npuas vim yog CO2 tso tawm sai dhau. Yuav kho li cas?

    Txo DMDE rau 0.1–0.2 phr thiab ntxiv cov tshuaj ntxuav dej xws li p-TSI.

    DMDE puas ua rau daj ntawm cov sealants xim dawb?

    Tsawg heev; nws yog ib qho morpholine derivative thiab paub txog kev ruaj khov xim zoo.

    Puas siv tau DMDE ua ke nrog lub tshuab ziab khaub ncaws zoo li molecular sieves?

    Yog, tab sis xyuas kom meej tias cov sieves tsis nqus DMDE; siv daim ntawv nplaum lossis ua ntej sib tov nrog plasticizer.

    Kuv cov tshuaj nplaum ua npuas dej ib feem (ua npuas dej tau) tsis muaj sijhawm khaws cia zoo. DMDE puas tuaj yeem ncua nws lub sijhawm?

    Yog, cov tshuaj DMDE-based tuaj yeem muaj lub sijhawm khaws cia ntawm 18-24 lub hlis hauv cov kaus poom aerosol.

    Qhov zoo ntawm DMDE dua li DBTDL hauv cov txheej txheem kho dej noo yog dab tsi?

    DMDE tsis muaj tshuaj lom (tsis muaj tin) thiab tsis ua rau hydrolysis ntawm cov pab pawg ester hauv polyester polyols.

    Kuv yuav ua li cas thiaj ua kom cov txheej ib feem kho tau sai dua thaum lub caij ntuj no txias thiab qhuav?

    Nce DMDE mus rau 1.2–1.5 phr thiab ntxiv cov tshuaj ua kom cov av noo zoo li cov tshuaj yaj uas pub dej.
