DI METHYL ETHANOLAMINE, ni ifumbire mvaruganda, imiti ya C5H13NO2, kubwamazi adafite ibara ryijimye cyangwa yijimye yijimye yamavuta, arashobora kwibeshya mumazi, inzoga, gushonga gato muri ether.Ahanini ikoreshwa nka emulifisiyeri na gaze ya acide, igenzura aside aside, catalizike ya polyurethane, ikoreshwa kandi nk'imiti igabanya ubukana nka azote ya hydrogloride ya azote.
Ibyiza:Ibicuruzwa bifite impumuro ya ammonia idafite ibara cyangwa ibara ry'umuhondo, irashya.Irashobora kwibeshya n'amazi, Ethanol, benzene, ether na acetone.Ubucucike bugereranije 0.8879, ingingo itetse 134,6 ℃.Ingingo yo gukonjesha - 59. O ℃.Ingingo yo gutwika 41 ℃.Flash point (fungura igikombe) 40 ℃.Viscosity (20 ℃) 3.8mPa.s.Igipimo cyangirika 1.4296.
Uburyo bwo kwitegura:
1.Imisemburo ya Ethylene na dimethylamine na Ethylene oxyde ammonia, binyuze muri distillation, distillation, dehydrasi.
2.Ibikorwa bya Chloroethanol bibonwa na saponification ya chloroethanol na alkali kugirango bibyare okiside ya Ethylene, hanyuma bigashyirwa hamwe na dimethylamine.
Porogaramu ya DMEA：
Igikorwa cya catalitiki ya N, N-dimethylethanolamine DMEA kiri hasi cyane, kandi ntigifite ingaruka nke mukuzamuka kwifuro na gel reaction, ariko dimethylethanolamine DMEA ifite alkaline ikomeye, ishobora guhungabanya neza urugero rwimiterere yibigize ifuro Acide, cyane cyane iyo muri isocyanates , bityo ugumane andi amine muri sisitemu.Igikorwa gito hamwe nubushobozi buke bwo kutabogama bwa dimethylethanolamine DMEA ikora nka buffer kandi ni byiza cyane iyo ikoreshejwe ifatanije na triethylenediamine, kuburyo igipimo cyifuzwa gishobora kugerwaho hamwe na triethylenediamine.
Dimethylethanolamine (DMEA) ifite uburyo bwinshi bwo gukoresha, nka: dimethylethanolamine DMEA irashobora gukoreshwa mugutegura ibishishwa byamazi;dimethylethanolamine DMEA nayo ni ibikoresho fatizo bya metethylaminoethyl methacrylate, ikoreshwa mugutegura imiti igabanya ubukana, imiterere yubutaka, ibikoresho bitwara ibintu, inyongeramusaruro nimpapuro;dimethylethanolamine DMEA nayo ikoreshwa mubikoresho byo gutunganya amazi kugirango birinde kwangirika.
Muri polyurethane ifuro, dimethylethanolamine DMEA ni co-cataliste hamwe na cataliste ikora, kandi dimethylethanolamine DMEA irashobora gukoreshwa mugutegura ifuro ryoroshye rya polyurethane hamwe nifuro ikomeye ya polyurethane.Hano hari hydroxyl groupe muri molekile ya dimethylethanolamine DMEA, ishobora kwitwara hamwe nitsinda rya isocyanate, bityo dimethylethanolamine DMEA irashobora guhuzwa na molekile ya polymer, kandi ntabwo izahinduka nka triethylamine.
Gupakira ibicuruzwa:Ukoresheje ingoma yingoma yicyuma, uburemere bwa 180 kg kuri buri ngoma.Ubike ahantu hakonje kandi uhumeka.Bika kandi utware ukurikije imiti yaka kandi ifite ubumara.
