DI METHYL ETHANOLAMINE, waa isku-dhis dabiici ah, qaacido kiimiko ah oo C5H13NO2 ah, oo loogu talagalay dareere saliid ah oo aan midab lahayn ama jaalle madow ah, waxaa lagu qasi karaa biyo, aalkolo, oo si yar ugu milmi kara ether. Inta badan waxaa loo isticmaalaa sida emulsifier iyo nuugista gaaska aashitada, wakiilka xakamaynta salka aashitada, kicinta xumbo polyurethane, sidoo kale waxaa loo isticmaalaa daawooyinka ka hortagga burooyinka sida nitrogen mustard hydrochloride dhexdhexaad.
Guryaha:Badeecadani waxay leedahay ur ammonia ah oo aan midab lahayn ama dareere huruud ah, oo guban kara. Waxaa lagu qasi karaa biyo, ethanol, benzene, ether iyo acetone. Cufnaanta qaraabada ah waa 0.8879, dhibicda karkaraya waa 134,6℃. Barta barafowga - 59. O℃. Barta shidista waa 41℃. Barta iftiiminta (koob furan) waa 40℃. Viscosity (20℃) waa 3.8mPa. s. Tusmada Refractive waa 1.4296.
Habka diyaarinta:
1. Habka oksaydhka Ethylene oo ay sameeyaan dimethylamine iyo ethylene oxide ammonia, iyada oo loo marayo kala-soocidda, kala-soocidda, iyo fuuq-baxa.
2. Habka Chloroethanol waxaa lagu helaa saponification-ka chloroethanol iyo alkali si loo soo saaro ethylene oxide, ka dibna lagu sameeyo dimethylamine.
Codsiyada DMEA:
Dhaqdhaqaaqa katalytic-ga ee N,N-dimethylethanolamine DMEA aad ayuu u hooseeyaa, saameyn yar ayuuna ku leeyahay kor u kaca xumbada iyo falcelinta jelka, laakiin dimethylethanolamine DMEA waxay leedahay alkalinity xooggan, taas oo si wax ku ool ah u dhexdhexaadin karta tirada raadadka ee qaybaha xumbo-samaynta. Asiidhada, gaar ahaan kuwa ku jira isocyanates, sidaas darteed waxay hayn karaan amines kale oo ku jira nidaamka. Dhaqdhaqaaqa hooseeya iyo awoodda dhexdhexaadinta sare ee dimethylethanolamine DMEA waxay u dhaqantaa sidii kayd waxayna si gaar ah faa'iido u leedahay marka la isticmaalo iyadoo lala kaashanayo triethylenediamine, si heerka falcelinta la rabo loo gaaro iyadoo la adeegsanayo fiirsasho yar oo triethylenediamine ah.
Dimethylethanolamine (DMEA) waxay leedahay isticmaallo kala duwan, sida: dimethylethanolamine DMEA waxaa loo isticmaali karaa diyaarinta dahaarka biyaha lagu milmi karo; dimethylethanolamine DMEA sidoo kale waa walxo cayriin ah oo loogu talagalay dimethylaminoethyl methacrylate, kaas oo loo isticmaalo diyaarinta wakiilada ka hortagga istaagga, qaboojiyeyaasha ciidda, walxaha gudbiya, waxyaabaha lagu daro waraaqaha iyo flocculants; dimethylethanolamine DMEA sidoo kale waxaa loo isticmaalaa wakiilada daaweynta biyaha si looga hortago miridhka kuleyliyaha.
Xumbo polyurethane, dimethylethanolamine DMEA waa isku-darka kicinta iyo kicinta falgalka ah, dimethylethanolamine DMEA-na waxaa loo isticmaali karaa qaabaynta xumbo polyurethane dabacsan iyo xumbo polyurethane adag. Waxaa jira koox hydroxyl ah oo ku jirta molecule-ka dimethylethanolamine DMEA, kaas oo la falgali kara kooxda isocyanate, sidaa darteed dimethylethanolamine DMEA waxaa lagu dari karaa molecule-ka polymer-ka, mana noqon doono mid kacsan sida triethylamine.
Baakadaha alaabta:Adigoo isticmaalaya baakad bir ah oo loogu talagalay in lagu xidho, miisaan saafi ah 180kg halkii foosto. Ku kaydi meel qabow oo hawo leh. Ku kaydi oo u rari sida kiimikooyinka guban kara oo sun ah.
