Umenzi wexabiso eliLungileyo DI METHYL ETHANOLAMINE (DMEA) CAS:108-01-0

Umsebenzi we-catalytic we-N, N-dimethylethanolamine DMEA iphantsi kakhulu, kwaye inempembelelo encinci ekukhuphukeni kwe-foam kunye nokuphendula kwejel, kodwa i-dimethylethanolamine DMEA ine-alkalinity eyomeleleyo, enokuthi ithintele ngokufanelekileyo inani lomkhondo kumacandelo e-foaming Acids, ngakumbi ezo zi-isocyanates, ngaloo ndlela zigcina ezinye ii-amines kwinkqubo. Umsebenzi ophantsi kunye nobuchule obuphezulu bokungathathi hlangothi kwe-dimethylethanolamine DMEA isebenza njenge-buffer kwaye inenzuzo ngakumbi xa isetyenziswe ngokudibeneyo ne-triethylenediamine, ukwenzela ukuba izinga lokuphendula elifunwayo linokufezekiswa ngokugxilwa okuphantsi kwe-triethylenediamine.

I-Dimethylethanolamine (i-DMEA) inoluhlu olubanzi lokusetyenziswa, njenge: i-dimethylethanolamine DMEA ingasetyenziselwa ukulungiselela iingubo ezichithwa ngamanzi; I-dimethylethanolamine i-DMEA iphinda ibe yinto eluhlaza ye-dimethylaminoethyl methacrylate, esetyenziselwa ukulungisa i-anti-Static agents, i-conditioners yomhlaba, izinto zokuqhuba, izongezo zephepha kunye ne-flocculants; I-dimethylethanolamine DMEA ikwasetyenziswa kwiiarhente zokunyanga amanzi ukuthintela ukubola kwebhoyila.

Kwi-polyurethane foam, i-dimethylethanolamine DMEA i-co-catalyst kunye ne-catalyst esebenzayo, kwaye i-dimethylethanolamine DMEA ingasetyenziselwa ukuqulunqwa kwe-flexible polyurethane foam kunye ne-polyurethane foam eqinile. Kukho iqela le-hydroxyl kwi-molecule ye-dimethylethanolamine DMEA, enokusabela kunye neqela le-isocyanate, ngoko ke i-dimethylethanolamine DMEA inokudibaniswa ne-polymer molecule, kwaye ayiyi kuba yinto ephazamisayo njenge-triethylamine.
