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

Umsebenzi we-catalytic we-N, N-dimethylethanolamine DMEA uphantsi kakhulu, kwaye unempembelelo encinci ekunyukeni kwegwebu kunye nokuphendula kwejeli, kodwa i-dimethylethanolamine DMEA ine-alkalinity eyomeleleyo, enokuthi ithintele ngokufanelekileyo inani lomkhondo kwizinto ezinogwebu lwe-Acids, ngakumbi ezo zikwi-isocyanates. , ngaloo ndlela gcina ezinye iiamines kwinkqubo.Umsebenzi ophantsi kunye nobuchule obuphezulu bokungathathi hlangothi kwe-dimethylethanolamine DMEA isebenza njenge-buffer kwaye inenzuzo ngakumbi xa isetyenziswe ngokudibanisa 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.
