Umkhiqizi Intengo Enhle I-Pentamethyldipropylenetriamine (PMDPTA) CAS:3855-32-1

Intengo Enhle Yomkhiqizi I-Pentamethyldipropylenetriamine (PMDPTA) CAS:3855-32-1 Isithombe Esifakiwe

incazelo emfushane:

I-PMDPTA iyi-catalyst ye-foam/gel enephunga eliphansi, engasetshenziswa ku-foam ethambile ye-polyurethane yohlobo lwe-polyether, amabhamuza aqinile e-polyurethane kanye nezinamathiselo zokumboza. I-PMDPTA isetshenziswa ikakhulukazi ku-foam ye-HR yesikhunta esibandayo. I-PMDPTA ibizwa ngokuthi i-five-base di-propyleneramine, enezinhlelo zokusebenza eziningi kuma-foam athambile naqinile ahlukahlukene. I-PMDPTA inganikeza impendulo yokuqala elinganiselayo kanye nempendulo ye-gel, futhi yandise isikhathi sokuphendula kwe-foam kanye nempendulo ye-gel. Le catalyst ayikwazi ukusetshenziswa yodwa kuphela, kodwa futhi ihlanganyela nezinye izi-catalyst kanye nama-ejenti asizayo. I-PMDPTA ingancibilikiswa ku-polyol ye-polyether.

Incibilika kalula ezincibilikisini eziningi. Ibhalansi yokusabela kwe-foam nejeli. Izinzuzo zisetshenziswa ku-foam ethambile, engagwema ukuqhekeka kanye nembobo ye-foam, enomsebenzi omuhle kakhulu wokuphakamisa. Thuthukisa ukucutshungulwa, ukubekezelela kanye nokusebenza kokulungisa ubuso be-foam eqinile. Thuthukisa imbobo ephezulu yepulasitiki ethambile ye-foam.

Izakhiwo zezakhiwo: iphuzu lokubila: 102 ° C / 1mmHg, ukuminyana: 0,83 g / cm3, inkomba yokubuyisa: 1.4450 kuya ku-1.4480, iphuzu le-flash: 92 ° C, i-acidity coefficient (PKA): 9.88 ± 0.28 (Ukubikezela). Isetshenziswa kakhulu kuma-phenol okuncibilikisa i-alkaline, futhi isetshenziselwa ama-inter-phenylphenols, njll., futhi ivame ukusetshenziswa njengezinto ezibangela ukusabela kwe-esterization kanye nokuphelelwa amanzi emzimbeni; i-dye intermediate

Izicelo ze-PMDPTA

I-Pentamethyldipropylenetriamine iyisikhuthazi se-foam/gel esinephunga eliphansi, esingasetshenziselwa i-polyether polyurethane foam ethambile, amabhamuza aqinile e-polyurethane, izembozo, izinamathiseli, njll., ezifanele kakhulu ukusetshenziswa kwe-Yu Cold Model HR Bubble. I-foam ivuliwe kahle futhi isetshenziswa enqubweni ye-Maxfoam foam, esebenza kahle kakhulu.
