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

kufotokozera mwachidule:

PMDPTA ndi chothandizira kulimbitsa thovu/gel chomwe chili ndi fungo lochepa, chomwe chingagwiritsidwe ntchito mu thovu lofewa la polyurethane la mtundu wa polyether, thovu lolimba la polyurethane ndi zomatira zokutira. PMDPTA imagwiritsidwa ntchito makamaka mu thovu lozizira la HR. PMDPTA imatchedwa five-base di-propyleneramine, yomwe imagwiritsidwa ntchito m'njira zosiyanasiyana mu thovu lofewa ndi lolimba. PMDPTA ikhoza kupereka yankho loyambira bwino komanso yankho la gel, ndikuwonjezera nthawi yoyankhira thovu ndi yankho la gel. Chothandizira ichi sichingagwiritsidwe ntchito chokha, komanso chimagawidwa ndi ma catalyst ena ndi othandizira. PMDPTA ikhoza kusungunuka mu polyol ya polyether.

Imasungunuka mosavuta mu zosungunulira zambiri. Kulinganiza bwino kwa thovu ndi gel. Ubwino wake umagwiritsidwa ntchito mu thovu lofewa, lomwe lingapewe kusweka ndi kubowola kwa thovu, lomwe lili ndi mphamvu yabwino kwambiri yokweza. Limakonza kusinthasintha, kulolerana, ndi magwiridwe antchito a thovu lolimba. Limakonza dzenje lapamwamba la pulasitiki yofewa.

Katundu wa katundu: kutentha: 102 ° C / 1mmHg, kuchulukana: 0,83 g / cm3, refractive index: 1.4450 mpaka 1.4480, flash point: 92 ° C, acidity coefficient (PKA): 9.88 ± 0.28 (Kuneneratu). Amagwiritsidwa ntchito makamaka pa alkaline melting phenols, komanso amagwiritsidwa ntchito pa inter-phenylphenols, ndi zina zotero, ndipo nthawi zambiri amagwiritsidwa ntchito ngati catalysts mu esterization ndi dehydration reactions; utoto wapakati

Kugwiritsa ntchito PMDPTA

Pentamethyldipropylenetriamine ndi chothandizira kulimbitsa thovu/gel chomwe chimakhala ndi fungo lochepa, chomwe chingagwiritsidwe ntchito pa thovu lofewa la polyether polyurethane, thovu lolimba la polyurethane, zokutira, zomatira, ndi zina zotero, makamaka zoyenera kugwiritsidwa ntchito pa Yu Cold Model HR Bubble. Thovu limatsegulidwa bwino ndipo limagwiritsidwa ntchito mu njira yopangira thovu ya Maxfoam, yomwe imagwira ntchito bwino kwambiri.
