Chaw tsim tshuaj paus zoo nqi DI methyl ethanolamine (DMEA) CAS: 108-01-0
Txhais lus hais tias
N, n-dimethyl-2-hydrotethylamine, 2-dimetethylaminoethanol
Cov ntawv thov ntawm DMEA
Cov kev ua si catalytic ntawm n, n-dimethylethangine DMEA muaj peev xwm tsawg heev, thiab nws muaj cov txiaj ntsig me me, tab sis tsis muaj txiaj ntsig rau hauv cov txheej txheem ua npuas dej acids, tshwj xeeb tshaj yog cov hauv Isocyanates , yog li khaws cia lwm cov amines hauv lub system. Qhov kev ua ub no tsawg thiab muaj peev xwm nruab nrab muaj peev xwm ntawm Doshleytisanoline D TheEs thiab yog tias cov tshuaj tiv thaiv zoo tshaj plaws uas tau ua tiav nrog cov tshuaj tiv thaiv qis ntawm trietylenediamine.
Dimethylethangine (DMEA) muaj ntau yam ntawm kev siv, xws li: Dretylethangethanbon DMEA tuaj yeem siv los npaj cov dej dej ntws; dimethylethatanolamine DMea kuj yog cov khoom siv raw rau cov neeg sawv cev ua kom muaj zog, cov khoom siv tsis zoo, cov ntaub ntawv sau, cov ntawv sau thiab flocculants; Dosethylethangamine D sawv ntxov kuj yog siv rau cov neeg sawv cev dej kom tiv thaiv kev xeb boiler.
Hauv polyurethane ua npuas dej, dimethylethanbon dmehlalthans thiab reathylethans thiab dimtive catulationanolamam ua npuas thiab siv zog polyurethane ua npuas ncauj. Muaj cov pab pawg hydroxyl hauv cov molecule ntawm Dostylethatanoline D sawv daws, thiab nws yuav ua ke nrog lub zog polymer, thiab nws yuav tsis yog volatile li triethylamine.
