Ngā tono o te DMEA

He tino iti te kaha whakaterenga o te N,N-dimethylethanolamine DMEA, ā, he iti noa iho tōna pānga ki te pikinga o te pahuka me te tauhohenga ira, engari he kaha te kawakore o te dimethylethanolamine DMEA, ka taea te whakakore i te iti o te huka i roto i ngā wāhanga huka. Ko ngā waikawa, inā koa ko ērā i roto i ngā isocyanates, ka pupuri i ētahi atu amine i roto i te pūnaha. Ko te iti o te mahi me te kaha whakakorenga teitei o te dimethylethanolamine DMEA ka mahi hei parepare, ā, he tino painga ina whakamahia tahitia me te triethylenediamine, kia taea ai te whakatutuki i te tere tauhohenga e hiahiatia ana me te iti o te kukū o te triethylenediamine.

He whānuitia ngā whakamahinga o te Dimethylethanolamine (DMEA), pēnei i: Ka taea te whakamahi i te dimethylethanolamine DMEA hei hanga i ngā paninga wairewa-wai; he rauemi mata anō hoki te dimethylethanolamine DMEA mō te dimethylaminoethyl methacrylate, e whakamahia ana hei hanga i ngā kaihoko anti-Static, ngā whakangawari oneone, ngā rauemi kawe hiko, ngā tāpiringa pepa me ngā flocculants; ka whakamahia anō hoki te dimethylethanolamine DMEA i roto i ngā kaihoko maimoatanga wai hei ārai i te waikura o ngā poihau.

I roto i te pahuka polyurethane, he kaiwhakaoho tahi te dimethylethanolamine DMEA, ā, he kaiwhakaoho tauhohe, ā, ka taea te whakamahi i te dimethylethanolamine DMEA i roto i te hanganga o te pahuka polyurethane ngāwari me te pahuka polyurethane pakari. He rōpū hydroxyl kei roto i te ngota ngota o te dimethylethanolamine DMEA, ka taea te tauhohe ki te rōpū isocyanate, nō reira ka taea te whakakotahi i te dimethylethanolamine DMEA me te ngota polymer, ā, e kore e tino pōrearea pērā i te triethylamine.
