Pentamethyldiethylenetriamine (pmdeta)

O le lima methyl two ethyleneamine tolu o se faʻamalosi malosi tele mo le tali polyurethane.E masani ona faʻaosoina le faʻafefete faʻafefe, ma faʻaaogaina foi e faapaleni ai le faʻafefe atoa ma gel tali.E faʻaaogaina lautele i ituaiga uma o polyurethane foam malo, e aofia ai le polyisocyanurate plate foam malo.Ona o lona malosi malosi, e mafai ona faʻaleleia le suavai o le foam, o lea e faʻaleleia ai le gaosiga o gaosiga ma faʻaleleia le tele o le gaosiga.E masani ona faʻasoa ma DMCHA ma isi.O le lima methyl ethyleneamine tolu amine e faʻaaogaina naʻo le faʻaogaina o le polyurethane foam formula, ma e mafai foʻi ona faʻasoa ma isi catalysts.0-2.0 vaega ile 100 vaega ole polyol.
I le faʻaopoopoga i le faʻapipiʻiina o le foam maʻaʻa, e mafai foi ona faʻaaogaina le lima methyl two ethyleneamine tolu i le gaosiga o le polyether polyurethane soft foam ma le foam foam.Mo se faʻataʻitaʻiga, o le 70% o le pentamethylenediethylenetriamine e masani ona faʻaaogaina i le faʻatulagaina o oloa faʻafefe vaivai.O le faʻamalosi e maualuga le gaioiga, vave faʻafefe vave, maualuga le malosi ma maualuga le gafatia.I le foam vaivai, 0.1-0.5 phr o le catalyst i le 100 phr o polyether e mafai ona sili atu le aafiaga.E mafai foʻi ona faʻaaogaina e fai ma faʻamalosi fesoasoani mo le foam malo.
O le lima methyl two ethyleneamine tolu amine quaternary ammonium masima o se faʻagata tuai mo foam vaivai, lea e faʻaaogaina e faʻaumi ai le taimi faʻafefe.E fetaui lelei mo oloa foam ma foliga lavelave ma ituaiga pusa foaming process, ma faʻaleleia le fausaga o le foam ma faʻaleleia le tulaga lelei.O le tele o ana lava vailaʻau e matua lautele, ma o le suiga o le vailaʻau e leai sona aafiaga manino i le taimi paʻepaʻe;Ae o le faʻateleina o le vailaʻau e mafai ona faʻapuʻupuʻu le taimi maualuga o le foam ma faʻapuʻupuʻu le taimi faʻamalolo.
