Awọn ohun elo DMEA
Iṣẹ ṣiṣe catalytic ti N, N-dimethylethanolamine DMEA ti lọ silẹ pupọ, ati pe o ni ipa diẹ lori dide foomu ati ifasẹ gel, ṣugbọn dimethylethanolamine DMEA ni alkalinity ti o lagbara, eyiti o le ṣe imunadoko iye itọpa ninu awọn paati foaming Acids, ni pataki awọn ti o wa ni isocyanates. , nitorina ni idaduro awọn amines miiran ninu eto naa.Iṣẹ kekere ati agbara didoju giga ti dimethylethanolamine DMEA ṣe bi ifipamọ ati pe o jẹ anfani ni pataki nigba lilo ni apapo pẹlu triethylenediamine, ki oṣuwọn ifasẹyin ti o fẹ le ṣee ṣe pẹlu awọn ifọkansi kekere ti triethylenediamine.
Dimethylethanolamine (DMEA) ni ọpọlọpọ awọn lilo, gẹgẹbi: dimethylethanolamine DMEA le ṣee lo lati ṣeto awọn ohun elo ti omi-dilutable;dimethylethanolamine DMEA tun jẹ ohun elo aise fun dimethylaminoethyl methacrylate, eyiti a lo lati ṣeto awọn aṣoju anti-Static, awọn amúṣantóbi ilẹ, awọn ohun elo imudani, awọn afikun iwe ati awọn flocculants;dimethylethanolamine DMEA tun lo ninu awọn aṣoju itọju omi lati ṣe idiwọ ipata igbomikana.
Ninu foam polyurethane, dimethylethanolamine DMEA jẹ oludasiṣẹ-apapọ ati oludasiṣẹ ifaseyin, ati dimethylethanolamine DMEA le ṣee lo ni iṣelọpọ ti foam polyurethane rọ ati foam polyurethane lile.Ẹgbẹ hydroxyl kan wa ninu moleku ti dimethylethanolamine DMEA, eyiti o le fesi pẹlu ẹgbẹ isocyanate, nitorinaa dimethylethanolamine DMEA le ni idapo pẹlu molecule polymer, ati pe kii yoo jẹ iyipada bi triethylamine.
