Umenzi Ixabiso Elihle I-Pentamethyldipropylenetriamine (PMDPTA) CAS:3855-32-1

inkcazo emfutshane:

I-PMDPTA yi-catalyst ye-foam/gel enuka kancinci, enokusetyenziswa kwi-polyurethane foam ethambileyo yohlobo lwe-polyether, amaqamza aqinileyo e-polyurethane kunye nezincamathelisi zokugquma. I-PMDPTA isetyenziswa ngakumbi kwi-cold mold HR foam. I-PMDPTA ibizwa ngokuba yi-five-base di-propyleneramine, enezicelo ezininzi kwiifoam ezahlukeneyo ezithambileyo neziqinileyo. I-PMDPTA inokubonelela ngempendulo yokuqala elungeleleneyo kunye nempendulo ye-gel, kwaye yandise ixesha lokuphendula kwe-foam kunye ne-gel. Le catalyst ayinakusetyenziswa yodwa kuphela, kodwa ikwabelana nezinye ii-catalysts kunye nee-arhente ezincedisayo. I-PMDPTA inokunyibilikiswa kwi-polyol ye-polyether.

Inyibilika lula kwiintlambululi ezininzi. Ibhalansi yempendulo yefoam kunye nejeli. Iingenelo zisetyenziswa kwi-soft block foam, enokuthi iphephe ukuqhekeka kunye nomngxuma we-pinhole yefoam, enomsebenzi ophakamileyo wokuphakamisa. Iphucula ukuqhubekeka kokusebenza, ukunyamezela kunye nokusebenza kokulungisa umphezulu wefoam eqinileyo. Iphucula umngxuma ophezulu weplastiki yefoam ethambileyo.

Iimpawu zeempawu: iqondo lokubila: 102 ° C / 1mmHg, uxinano: 0,83 g / cm3, isalathisi sokurhawuzelela: 1.4450 ukuya kwi-1.4480, iqondo lokutsha: 92 ° C, i-acidity coefficient (PKA): 9.88 ± 0.28 (Ingxelo). Isetyenziswa kakhulu kwi-alkaline melting phenols, kwaye ikwasetyenziswa kwi-inter-phenylphenols, njl.njl., kwaye isetyenziswa rhoqo njengee-catalysts kwi-esterization kunye ne-dehydration reactions; i-dye intermediate

Izicelo ze-PMDPTA

I-Pentamethyldipropylenetriamine sisincedisi sokulinganisela i-foam/gel esinevumba eliphantsi, esinokusetyenziselwa i-polyether polyurethane foam ethambileyo, amaqamza aqinileyo e-polyurethane, ii-coating, izincamathelisi, njl.njl., zilungele ukusetyenziswa kwi-Yu Cold Model HR Bubble. I-foam ivuliwe kakuhle kwaye isetyenziswa kwinkqubo ye-Maxfoam foam, esebenza kakuhle kakhulu.
