Mtengo Wabwino Wopanga DI METHYL ETHANOLAMINE (DMEA) CAS:108-01-0

Ntchito yothandiza ya N,N-dimethylethanolamine DMEA ndi yotsika kwambiri, ndipo siikhudza kwambiri kukwera kwa thovu ndi gel reaction, koma dimethylethanolamine DMEA ili ndi alkalinity yamphamvu, yomwe imatha kuletsa kuchuluka kwa ma acids m'zigawo za thovu. Ma acids, makamaka omwe ali mu isocyanates, motero amasunga ma amine ena m'dongosolo. Ntchito yochepa komanso kuthekera kwakukulu koletsa kwa dimethylethanolamine DMEA kumagwira ntchito ngati buffer ndipo ndi yopindulitsa kwambiri ikagwiritsidwa ntchito limodzi ndi triethylenediamine, kotero kuti kuchuluka kwa zomwe mukufuna kuchita kungapezeke ndi kuchuluka kochepa kwa triethylenediamine.

Dimethylethanolamine (DMEA) imagwiritsidwa ntchito m'njira zosiyanasiyana, monga: dimethylethanolamine DMEA ingagwiritsidwe ntchito pokonza zokutira zosungunuka m'madzi; dimethylethanolamine DMEA ndi chinthu chopangira dimethylaminoethyl methacrylate, chomwe chimagwiritsidwa ntchito pokonza zinthu zotsutsana ndi kutentha, zoziziritsa kukhosi, zinthu zoyendetsera mpweya, zowonjezera pamapepala ndi zinthu zothira madzi; dimethylethanolamine DMEA imagwiritsidwanso ntchito pochiza madzi kuti apewe dzimbiri la boiler.

Mu thovu la polyurethane, dimethylethanolamine DMEA ndi co-catalyst komanso chothandizira chothandizira, ndipo dimethylethanolamine DMEA ingagwiritsidwe ntchito popanga thovu la polyurethane losinthasintha ndi thovu la polyurethane lolimba. Pali gulu la hydroxyl mu molekyulu ya dimethylethanolamine DMEA, yomwe imatha kuchita ndi gulu la isocyanate, kotero dimethylethanolamine DMEA ikhoza kuphatikizidwa ndi molekyulu ya polima, ndipo sidzakhala yosinthasintha ngati triethylamine.
