Nga kupu taurite
N,N-Dimethyl-2-hydroxyethylamine, 2-dimethylaminoethanol
Nga tono a DMEA
Ko te mahi catalytic o N,N-dimethylethanolamine DMEA he iti rawa, he iti te paanga ki te piki o te pahuka me te tauhohenga ra, engari he kaha te kawakore o te dimethylethanolamine DMEA, ka taea te whakakore i te nui o nga waahanga o te hukahuka waikawa, ina koa ko nga mea kei roto i te isocyanates. , na reira ka mau etahi atu amine i roto i te punaha.Ko te iti o te ngohe me te kaha whakaheke teitei o te dimethylethanolamine DMEA ka mahi hei parepare me te tino painga ina whakamahia me te triethylenediamine, kia taea ai te tere tauhohenga e hiahiatia ana me te iti o te kukume o te triethylenediamine.
Ko te Dimethylethanolamine (DMEA) he maha nga whakamahinga, penei: ka taea te whakamahi i te dimethylethanolamine DMEA ki te whakarite i nga paninga wai-diluted;Ko te dimethylethanolamine DMEA ano he rauemi mata mo te dimethylaminoethyl methacrylate, e whakamahia ana hei whakarite i nga anti- Static agents, conditioners soil, conductive material, paper additives and flocculants;Ka whakamahia ano te dimethylethanolamine DMEA i roto i nga kaihoko maimoatanga wai hei aukati i te pirau o te kohua.
I roto i te pahuka polyurethane, ko te dimethylethanolamine DMEA he whakakorikori tahi me te whakakorikori reactive, a ka taea te whakamahi dimethylethanolamine DMEA i roto i te hanga o te pahuka polyurethane ngawari me te pahuka polyurethane pakari.He roopu hydroxyl kei roto i te ngota ngota o te dimethylethanolamine DMEA, ka taea te tauhohe me te roopu isocyanate, na reira ka taea te whakakotahi te dimethylethanolamine DMEA me te ngota ngota polymer, a ka kore e rite ki te triethylamine.
