Kumukūʻai maikaʻi o ka mea hana DI METHYL ETHANOLAMINE (DMEA) CAS:108-01-0

He haʻahaʻa loa ka hana catalytic o N,N-dimethylethanolamine DMEA, a he liʻiliʻi kona hopena i ka piʻi ʻana o ka huʻa a me ka hopena gel, akā he alkalinity ikaika ko ka dimethylethanolamine DMEA, hiki ke hoʻopau pono i ka nui o nā mea i loko o nā ʻāpana hua. ʻO nā waikawa, ʻoi aku hoʻi i nā isocyanates, no laila e mālama i nā amine ʻē aʻe i loko o ka ʻōnaehana. ʻO ka hana haʻahaʻa a me ka hiki ke hoʻopau kiʻekiʻe o ka dimethylethanolamine DMEA e hana ma ke ʻano he buffer a he mea maikaʻi loa ia i ka wā e hoʻohana ʻia ai me ka triethylenediamine, i hiki ai ke hoʻokō ʻia ka wikiwiki o ka hopena i makemake ʻia me nā haʻahaʻa haʻahaʻa o ka triethylenediamine.

He ākea nā hoʻohana o Dimethylethanolamine (DMEA), e like me: hiki ke hoʻohana ʻia ka dimethylethanolamine DMEA e hoʻomākaukau i nā uhi wai-dilutable; ʻO ka dimethylethanolamine DMEA kahi mea maka no ka dimethylaminoethyl methacrylate, i hoʻohana ʻia e hoʻomākaukau i nā mea anti-Static, nā mea hoʻomaʻamaʻa lepo, nā mea conductive, nā mea hoʻohui pepa a me nā flocculants; Hoʻohana ʻia ka dimethylethanolamine DMEA i nā mea mālama wai e pale aku i ka pala o ka paila.

I loko o ka huʻa polyurethane, ʻo dimethylethanolamine DMEA kahi mea hoʻouluulu a me kahi mea hoʻouluulu reactive, a hiki ke hoʻohana ʻia ka dimethylethanolamine DMEA i ka hana ʻana o ka huʻa polyurethane palupalu a me ka huʻa polyurethane paʻa. Aia kahi hui hydroxyl i loko o ka mole o dimethylethanolamine DMEA, hiki ke hana me ka hui isocyanate, no laila hiki ke hui pū ʻia ka dimethylethanolamine DMEA me ka mole polymer, a ʻaʻole ia e like me ka volatile e like me triethylamine.
