Mashoko anoreva zvakafanana

N, N-Dimethyl-2-hydroxyethylamine, 2-dimethylaminoethanol

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.
