Umenzi Ixabiso Elihle DI METHYL ETHANOLAMINE (DMEA) CAS:108-01-0

Umsebenzi we-catalytic we-N,N-dimethylethanolamine DMEA uphantsi kakhulu, kwaye awunampembelelo ingako ekunyukeni kwe-foam kunye ne-gel reaction, kodwa i-dimethylethanolamine DMEA ine-alkalinity enamandla, enokuthi inciphise ngempumelelo inani le-trace kwi-foam components. Ii-Acids, ingakumbi ezo zikwi-isocyanates, ngaloo ndlela zigcina ezinye ii-amines kwinkqubo. Umsebenzi ophantsi kunye nokukwazi okuphezulu kwe-dimethylethanolamine DMEA kusebenza njenge-buffer kwaye kuluncedo ngakumbi xa kusetyenziswa kunye ne-triethylenediamine, ukuze izinga lokuphendula elifunekayo lifezekiswe ngoxinzelelo oluphantsi lwe-triethylenediamine.

I-Dimethylethanolamine (DMEA) ineendlela ezahlukeneyo zokusetyenziswa, ezinje ngezi: i-dimethylethanolamine I-DMEA ingasetyenziselwa ukulungisa izinto ezixutywa ngamanzi; i-dimethylethanolamine I-DMEA ikwayinto eluhlaza ye-dimethylaminoethyl methacrylate, esetyenziselwa ukulungiselela ii-anti-Static agents, izinto zokulungisa umhlaba, izinto eziqhuba amanzi, izongezo zephepha kunye nee-flocculants; i-dimethylethanolamine I-DMEA ikwasetyenziswa kwii-arhente zonyango lwamanzi ukuthintela ukugqwala kwebhoyila.

Kwi-polyurethane foam, i-dimethylethanolamine DMEA yi-co-catalyst kunye ne-reactive catalyst, kwaye i-dimethylethanolamine DMEA ingasetyenziswa ekwenzeni i-polyurethane foam eguquguqukayo kunye ne-polyurethane foam eqinileyo. Kukho iqela le-hydroxyl kwi-molecule ye-dimethylethanolamine DMEA, enokusabela neqela le-isocyanate, ngoko ke i-dimethylethanolamine DMEA inokudityaniswa ne-polymer molecule, kwaye ayiyi kuba ne-volatious njenge-triethylamine.
