I-PMDPTA iwumthombo we-foam/gel balance balance-nuka kancane, engasetshenziswa ku-polyether -uhlobo lwe-polyurethane igwebu elithambile, amabhamuza aqinile e-polyurethane nezinamatheliso zokunamathela.I-PMDPTA isetshenziswa ikakhulukazi esikhunjeni esibandayo se-HR foam.I-PMDPTA ibizwa nge-five -base di -propyleneramine, enohlu olubanzi lwezinhlelo zokusebenza kumagwebu athambile naqinile ahlukahlukene.I-PMDPTA inganikeza impendulo yokuqala elinganiselayo kanye nempendulo yejeli, futhi yandise ukusabela kwegwebu kanye nesikhathi sokuphendula ijeli.Le catalyst ayikwazi ukusetshenziswa yodwa kuphela, kodwa futhi yabelana namanye ama-catalysts nama-axiliary agents.I-PMDPTA ingancibilika ku-polyether polyol.
Incibilika kalula kuma-solvents amaningi.Ibhalansi yokusabela kwegwebu nejeli.Izinzuzo zisetshenziselwa i-foam block block, engagwema ukuqhekeka kanye ne-pinhole ye-foam, enomsebenzi omuhle kakhulu wokuphakamisa.Thuthukisa ukucutshungulwa, ukubekezelelana kanye nokusebenza kokwelapha okungaphezulu kwegwebu eliqinile.Thuthukisa imbobo ephakeme yepulasitiki yegwebu elithambile.
Izakhiwo zezakhiwo: iphoyinti elibilayo: 102 ° C / 1mmHg, ukuminyana: 0,83 g / cm3, inkomba ye-refractive: 1.4450 kuya ku-1.4480, i-flash point: 92 ° C, i-acidity coefficient (PKA): 9.88 ± 0.28 (Predict).Isetshenziselwa ikakhulukazi i-alkaline melting phenols, futhi isetshenziselwa i-inter-phenylphenols, njll., futhi ivame ukusetshenziswa njengama-catalysts ekuphenduleni kwe-esterization kanye nokuphelelwa amandla kwamanzi;udayi ophakathi
