Cov ntawv thov ntawm DMEA

Qhov kev ua haujlwm catalytic ntawm N,N-dimethylethanolamine DMEA yog qis heev, thiab nws muaj me ntsis cuam tshuam rau kev nce ntawm cov ua npuas ncauj thiab cov tshuaj tiv thaiv gel, tab sis dimethylethanolamine DMEA muaj zog alkalinity, uas tuaj yeem ua kom cov kua qaub tsis muaj zog hauv cov khoom ua npuas ncauj, tshwj xeeb tshaj yog cov hauv isocyanates, yog li khaws lwm cov amines hauv lub cev. Qhov kev ua haujlwm qis thiab muaj peev xwm ua kom tsis muaj zog ntawm dimethylethanolamine DMEA ua haujlwm ua lub buffer thiab tshwj xeeb tshaj yog thaum siv ua ke nrog triethylenediamine, yog li qhov nrawm xav tau tuaj yeem ua tiav nrog cov concentration qis ntawm triethylenediamine.

Dimethylethanolamine (DMEA) muaj ntau yam kev siv, xws li: dimethylethanolamine DMEA tuaj yeem siv los npaj cov txheej txheem dej-dilutable; dimethylethanolamine DMEA kuj tseem yog cov khoom siv raw rau dimethylaminoethyl methacrylate, uas yog siv los npaj cov neeg sawv cev tiv thaiv Static, av conditioners, conductive cov ntaub ntawv, cov ntawv ntxiv thiab flocculants; dimethylethanolamine DMEA kuj tseem siv rau hauv cov neeg sawv cev kho dej kom tiv thaiv kev xeb boiler.

Hauv polyurethane ua npuas ncauj, dimethylethanolamine DMEA yog ib qho co-catalyst thiab ib qho reactive catalyst, thiab dimethylethanolamine DMEA tuaj yeem siv rau hauv kev tsim cov polyurethane ua npuas ncauj thiab polyurethane ua npuas ncauj. Muaj ib pawg hydroxyl hauv lub molecule ntawm dimethylethanolamine DMEA, uas tuaj yeem cuam tshuam nrog isocyanate pawg, yog li dimethylethanolamine DMEA tuaj yeem ua ke nrog lub molecule polymer, thiab nws yuav tsis volatile zoo li triethylamine.
