ʻO DI METHYL ETHANOLAMINE, he mea hoʻohuihui kino, ʻano kemika C5H13NO2, no ka wai ʻaila melemele ʻole a ʻeleʻele paha, hiki ke hoʻopili ʻia me ka wai, ka waiʻona, hiki ke hoʻoheheʻe ʻia i ka etera.Hoʻohana nui ʻia e like me ka emulsifier a me ke kinoea absorbent, acid base control agent, polyurethane foam catalyst, hoʻohana pū ʻia e like me nā lāʻau antitumor e like me ka nitrogen mustard hydrochloride intermediate.
Nā waiwai:Loaʻa kēia huahana i ka ʻala amonia ʻaʻole waihoʻoluʻu a melemele paha, hiki ke puhi.Hiki ke hoʻopili ʻia me ka wai, ethanol, benzene, ether a me ka acetone.ʻO ka mānoanoa pili 0.8879, wahi hoʻolapalapa 134,6 ℃.Ka helu hau – 59. O℃.He 41 ℃ ke kiko ʻā.Ke kiko uila (ke kīʻaha hāmama) 40 ℃.ʻO ka viscosity (20 ℃) 3.8mPa.s.Hōʻike hoʻohālikelike 1.4296.
Kaʻina hoʻomākaukau:
1.Ethylene oxide kaʻina e ka dimethylamine a me ka ethylene oxide ammonia, ma o ka distillation, distillation, dehydration.
Loaʻa ka hana 2.Chloroethanol e ka saponification o ka chloroethanol a me ka alkali e hana i ka ethylene oxide, a laila synthesized me ka dimethylamine.
Nā noi o DMEA：
ʻO ka hana catalytic o N, N-dimethylethanolamine DMEA he haʻahaʻa loa, a he liʻiliʻi kona hopena i ka piʻi ʻana o ka hupa a me ka hopena gel, akā he alkalinity ikaika ka dimethylethanolamine DMEA, hiki ke hoʻopau maikaʻi i ka nui o nā mea hoʻoheheʻe ʻana i nā ʻāpana Acids, ʻoi aku ka poʻe i loko o isocyanates. , pēlā e mālama ai i nā amine ʻē aʻe i loko o ka ʻōnaehana.ʻO ka haʻahaʻa haʻahaʻa a me ka ikaika neutralizing kiʻekiʻe o ka dimethylethanolamine DMEA e hana ma ke ʻano he pale a ʻoi aku ka maikaʻi ke hoʻohana ʻia me ka triethylenediamine, i hiki ke hoʻokō ʻia ka nui o ka hopena i makemake ʻia me nā haʻahaʻa haʻahaʻa o triethylenediamine.
ʻO ka Dimethylethanolamine (DMEA) he nui nā mea hoʻohana, e like me: dimethylethanolamine DMEA hiki ke hoʻohanaʻia no ka hoʻomākaukauʻana i ka wai-dilutable coatings;ʻO dimethylethanolamine DMEA kekahi mea maka no ka dimethylaminoethyl methacrylate, i hoʻohana ʻia e hoʻomākaukau i nā mea anti- Static, nā mea hoʻonaninani lepo, nā mea conductive, nā mea hoʻohui pepa a me nā flocculants;Hoʻohana pū ʻia ka dimethylethanolamine DMEA i nā mea lapaʻau wai e pale ai i ka ʻino o ka paila.
I loko o ka polyurethane foam, dimethylethanolamine DMEA he co-catalyst a me ka reactive catalyst, a hiki ke hoʻohana ʻia ka dimethylethanolamine DMEA i ka hoʻokumu ʻana o ka polyurethane foam maʻalahi a me ka pahu polyurethane paʻa.Aia kekahi hui hydroxyl i loko o ka mole o ka dimethylethanolamine DMEA, hiki ke hana me ka hui isocyanate, no laila hiki ke hoʻohui ʻia ka dimethylethanolamine DMEA me ka mole polymer, a ʻaʻole ia e like me ka triethylamine.
Puke huahana:Me ka hoʻohana ʻana i ka pahu pahu hao, ke kaumaha ʻupena 180kg no ka pahu.E mālama i kahi anuanu a me ka makani.E mālama a lawe ʻia e like me nā mea ʻona a me nā mea ʻona.
