DI METHYL ETHANOLAMINE, o se faʻalapotopotoga faʻapitoa, vailaʻau C5H13NO2, mo le lanu samasama poʻo le lanu samasama o le suauʻu vai, e mafai ona faʻafefiloi i le vai, ava malosi, soluble i le eter.E masani ona faʻaaogaina e pei o le emulsifier ma le acid gas absorbent, acid base control agent, polyurethane foam catalyst, faʻaaogaina foi e avea ma vailaʻau faʻamaʻi e pei o le nitrogen sinapi hydrochloride intermediate.
Meatotino:O lenei oloa e iai le manogi ammonia e leai se lanu pe samasama vai, e mu.E mafai ona faʻafefiloi ma vai, ethanol, benzene, eter ma acetone.Tulaga va'aiga 0.8879, mea fa'apuna 134,6 ℃.Fa'a'aisa – 59. O℃.Fa'amumu 41 ℃.Ipu moli (ipu tatala) 40℃.Viscosity (20 ℃) 3.8mPa.s.Fa'asinomaga fa'afoliga 1.4296.
Sauniuniga auala:
1. Ethylene oxide faagasologa e dimethylamine ma ethylene oxide ammonia, e ala i le distillation, distillation, dehydration.
2.Chloroethanol faagasologa e maua e le saponification o chloroethanol ma alkali e maua ai le ethylene oxide, ona synthesized ma dimethylamine.
Talosaga a DMEA:
O le catalytic gaoioiga o le N, N-dimethylethanolamine DMEA e matua maualalo, ma e itiiti sona aafiaga i le foam tulai ma gel tali, ae o le dimethylethanolamine DMEA e malosi alkalinity, lea e mafai ona faaitiitia lelei le aofaiga o vaega foaming acids, aemaise lava i latou i isocyanates. , o lea e taofia ai isi amine i le tino.O le gaioiga maualalo ma le maualuga o le neutralizing le gafatia o le dimethylethanolamine DMEA e galue e pei o se paʻu ma e sili ona aoga pe a faʻaoga faʻatasi ma le triethylenediamine, ina ia mafai ona ausia le fua o le tali manaʻomia i le maualalo o faʻatonuga o le triethylenediamine.
Dimethylethanolamine (DMEA) o loʻo i ai le tele o faʻaoga, e pei o le: dimethylethanolamine DMEA e mafai ona faʻaaogaina e saunia ai le faʻafefe vai;o le dimethylethanolamine DMEA foi o se mea mataʻutia mo le dimethylaminoethyl methacrylate, lea e faʻaaogaina e saunia ai anti- Static agents, faʻamaʻi eleele, mea faʻapipiʻi, mea faʻapipiʻi pepa ma flocculants;dimethylethanolamine DMEA o loʻo faʻaaogaina foi i vailaʻau togafitiga vai e puipuia ai le pala.
I le polyurethane foam, o le dimethylethanolamine DMEA o se co-catalyst ma se reactive catalyst, ma le dimethylethanolamine DMEA e mafai ona faʻaaogaina i le faʻaogaina o le polyurethane foam fetuutuunai ma le polyurethane foam malosi.O loʻo i ai se vaega hydroxyl i le mole o le dimethylethanolamine DMEA, lea e mafai ona tali atu i le isocyanate group, o lea e mafai ai ona tuʻufaʻatasia le dimethylethanolamine DMEA ma le polymer mole, ma o le a le faʻafefeteina e pei o le triethylamine.
afifiina o oloa:Fa'aaogā pusa pa'u u'amea, mamafa mama 180kg i le pa'u.Teu i se nofoaga malulu ma ea.Teu ma felauaiga e tusa ai ma vailaau e mu ma oona.
