Ifomula yolwakhiwo:

Iimpawu zomzimba kunye neekhemikhali

I-N-Ethylmorpholine ilulwelo olungenambala ukuya kumthubi kancinane kunye ne-viscosity (23 ° C) ye-2.3mPa.s, ingxinano ye-0.916, i-refractive index (23 ° C) ye-1.4415, indawo ebilayo ye-138 ~ 139 ° C. , kunye nendawo yokukhenkceza -60 ~-63℃, i-flash point (TCC) yi-32℃, uxinzelelo lomphunga (20℃) yi-813Pa. Inyibilika emanzini, iPka=7.8.

Ukucoceka kwemveliso ≧98% okanye ≧99%, ukufuma ≦0.5

Iimpawu kunye nokusetyenziswa

Ingasetyenziswa njenge-catalyst kwintsimi ye-PU kwaye inevumba elincinci kune-NMM. I-N-ethylmorpholine idla ngokusetyenziswa njenge-solvent ye-oyile kunye ne-resin, kwaye ingasetyenziselwa njengendawo ephakathi kwi-organic synthesis. Okwangoku, ezinye iinkampani ezifana neeMveliso zoMoya kunye neMomentive zibonakala ngathi azisayiboneleli le mveliso.

I-N-ethylmorpholine kunye ne-N-methylmorpholine yi-medium-strength tertiary tertiary amine catalysts, ilungele ngokukodwa ukuveliswa kwe-polyester-type flexible polyurethane foams kunye nokusebenza kakuhle kwesikhumba. I-N-ethylmorpholine isenokuthi ibe nefuthe elinamandla le-catalytic kwi-gel reaction emva kokuba i-foam iphakame kwinqanaba eliphezulu, ukwandisa iiseli ukuya kumlinganiselo ophezulu. Ngaphezu koko, ukusabela kogwebu kunye neereyithi zokuphendula kwe-gelation aziyi kutshintsha kakhulu ngenxa yoxinzelelo olwahlukileyo lwe-catalyst, kodwa into engalunganga livumba elinamandla.
