I-PMDPTA yi-foam enuka kancinci / i-gel balance catalyst, enokusetyenziswa kwi-polyether-type polyurethane foam ethambileyo, i-polyurethane amaqamza aqinileyo kunye ne-adhesives yokugubungela.I-PMDPTA isetyenziswa ngokukodwa kwi-foam ye-HR ebandayo.I-PMDPTA ibizwa ngokuba yi-five -base di -propyleneramine, enoluhlu olubanzi lwezicelo kwiifoam ezahlukeneyo ezithambileyo nezilukhuni.I-PMDPTA inokubonelela ngempendulo yokuqala elinganiselayo kunye nempendulo ye-gel, kwaye yandise ukuphendula kwe-foam kunye nexesha lokuphendula i-gel.Le catalyst ayikwazi ukusetyenziswa yodwa kuphela, kodwa ikwabelana nezinye ii-catalysts kunye nee-agent agents.I-PMDPTA inokunyibilika kwi-polyether polyol.
Inyibilika ngokulula kwizinyibilikisi ezininzi.I-foam kunye ne-gel reaction balance.Izibonelelo zisetyenziselwa i-foam yebhloko ethambileyo, enokuphepha ukuqhekeka kunye ne-pinhole ye-foam, enomsebenzi obalaseleyo wokuphakamisa.Ukuphucula ukusetyenzwa, ukunyamezela kunye nokunyanga umphezulu ukusebenza kwegwebu eliqinileyo.Phucula umngxuma ophezulu weplastiki yogwebu ethambileyo.
Iipropathi zepropati: indawo yokubilisa: 102 ° C / 1mmHg, ubuninzi: 0,83 g / cm3, isalathisi se-refractive: 1.4450 ukuya kwi-1.4480, i-flash point: 92 ° C, i-acidity coefficient (PKA): 9.88 ± 0.28 (Ukuxela kwangaphambili).Isetyenziselwa ikakhulu kwi-alkaline melting phenols, kwaye ikwasetyenziselwa i-inter-phenylphenols, njl., kwaye ihlala isetyenziswa njenge-catalysts kwi-esterization kunye ne-dehydration reactions;Idayi ephakathi
