Wopanga Mtengo Wabwino Pentamethyldipropylenetriamine (PMDPTA) CAS:3855-32-1

Kufotokozera mwachidule:

PMDPTA ndi chothandizira chochepa kwambiri cha thovu/gel osakaniza, chomwe chitha kugwiritsidwa ntchito popanga thovu lofewa la polyether-mtundu wa polyurethane, thovu lolimba la polyurethane ndi zomatira zokutira. PMDPTA imagwiritsidwa ntchito makamaka pakhungu lozizira la HR. PMDPTA imatchedwa five -base di -propyleneramine, yomwe imakhala ndi ntchito zambiri mumitundu yofewa komanso yovuta. PMDPTA ikhoza kupereka kuyankha koyenera koyambira ndi kuyankha kwa gel, ndikuwonjezera kachitidwe ka thovu ndi nthawi yoyankhira gel. Chothandizira ichi sichikhoza kugwiritsidwa ntchito chokha, komanso kugawana ndi othandizira ena ndi othandizira. PMDPTA imatha kusungunuka mu polyether polyol.

Imasungunuka mosavuta mu zosungunulira zambiri. Foam ndi gel reaction balance. Ubwino wake umagwiritsidwa ntchito mu thovu lofewa, lomwe lingapewe kung'ambika ndi kupindika kwa thovu, lomwe limakhala ndi ntchito yabwino yokweza. Limbikitsani kusinthika, kulolerana ndi kuchiritsa kwapamwamba kwa thovu lolimba. Konzani bowo lapamwamba la pulasitiki ya thovu yofewa.

Katundu wa katundu: otentha mfundo: 102 ° C / 1mmHg, kachulukidwe: 0,83 g / cm3, refractive index: 1.4450 kuti 1.4480, kung'anima mfundo: 92 ° C, acidity coefficient (PKA): 9.88 ± 0.28 (Predict). Amagwiritsidwa ntchito kwambiri pakusungunuka kwa alkaline phenols, komanso kugwiritsidwa ntchito kwa inter-phenylphenols, ndi zina zambiri, ndipo nthawi zambiri amagwiritsidwa ntchito ngati chothandizira mu esterization ndi kuchepa kwa madzi m'thupi; utoto wapakatikati

Mapulogalamu a PMDPTA

Pentamethyldipropylenetriamine ndi otsika kununkhira thovu / gel osakaniza bwino chothandizira, amene angagwiritsidwe ntchito polyether polyurethane thovu zofewa, polyurethane thovu zolimba, zokutira, zomatira, etc., makamaka oyenera ntchito Yu Cold Model HR Bubble. Chithovucho chimatsegulidwa bwino ndipo chimagwiritsidwa ntchito pochita thovu la Maxfoam, lomwe limagwira ntchito bwino kwambiri.
