DI METHYL ETHANOLAMINE, is an organic compound, chemical formula C5H13NO2, yemvura isina ruvara kana yakasviba yero ine mafuta, inogona kusanganiswa nemvura, doro, zvishoma soluble muether.Inonyanya kushandiswa se emulsifier uye asidi gasi inonwisa, acid base control agent, polyurethane foam catalyst, inoshandiswawo se antitumor mishonga yakadai senitrogen yemasitadhi hydrochloride yepakati.
Properties:Ichi chigadzirwa chine ammonia inonhuhwirira isina ruvara kana yero mvura, inopfuta.Inogona kusanganiswa nemvura, ethanol, benzene, ether uye acetone.Hukama density 0.8879, boiling point 134,6 ℃.Kutonhora kwechando - 59. O℃.Ignition point 41 ℃.Flash point (kapu yakazaruka) 40 ℃.Viscosity (20 ℃) 3.8mPa.s.Refractive index 1.4296.
Kugadzirira nzira:
1.Ethylene oxide process ne dimethylamine uye ethylene oxide ammonia, kuburikidza ne distillation, distillation, dehydration.
2.Chloroethanol process inowanikwa ne saponification ye chloroethanol uye alkali kuti ibudise ethylene oxide, uye inobva yagadzirwa ne dimethylamine.
Zvikumbiro zveDMEA:
Iyo inokonzeresa chiitiko cheN, N-dimethylethanolamine DMEA yakadzikira zvakanyanya, uye haina mhedzisiro yekusimuka kwefuro uye gel reaction, asi dimethylethanolamine DMEA ine alkalinity yakasimba, inogona kunyatso kudzikamisa huwandu hwekutsvaga muzvikamu zvinopupuma Acids, kunyanya izvo zviri isocyanates. , saka chengetedza mamwe maamine muhurongwa.Iyo yakaderera chiitiko uye yakakwirira neutralizing kugona kwe dimethylethanolamine DMEA inoita senge buffer uye inonyanya kubatsira kana yakashandiswa pamwe chete ne triethylenediamine, kuitira kuti inodiwa yekuita chiyero inogona kuwanikwa nekudzika kwakadzika kwe triethylenediamine.
Dimethylethanolamine (DMEA) ine zvakawanda zvakasiyana-siyana zvekushandisa, zvakadai se: dimethylethanolamine DMEA inogona kushandiswa kugadzira mvura-dilutable coatings;dimethylethanolamine DMEA zvakare chinhu chakasvibirira che dimethylaminoethyl methacrylate, iyo inoshandiswa kugadzira anti-Static agents, ivhu conditioners, conductive zvinhu, mapepa ekuwedzera uye flocculants;dimethylethanolamine DMEA inoshandiswawo mumishonga yekurapa mvura kudzivirira kuomarara kwebhailer.
Mu polyurethane furo, dimethylethanolamine DMEA inokonzeresa uye inoshanda inokonzeresa, uye dimethylethanolamine DMEA inogona kushandiswa mukugadzira inochinjika polyurethane furo uye rigid polyurethane furo.Kune boka re hydroxyl mumorekuru we dimethylethanolamine DMEA, inogona kuita neboka re isocyanate, saka dimethylethanolamine DMEA inogona kusanganiswa nepolymer molecule, uye haizove yakasvibiswa se triethylamine.
Product package:Uchishandisa iron dhiramu kurongedza, mambure uremu 180kg per dhiramu.Chengeta munzvimbo inotonhorera uye ine mhepo.Chengetedza uye takura zvinoenderana nemakemikari anopisa uye ane chepfu.
