Igiciro cyiza cy'umukozi Pentamethyldipropylenetriamine (PMDPTA) CAS: 3855-32-1

Igiciro cyiza cy'umukora Pentamethyldipropylenetriamine (PMDPTA) CAS: 3855-32-1 Ishusho yagaragaye

ibisobanuro bigufi:

PMDPTA ni catalyst ifite impumuro nkeya y'ifuro/gel, ishobora gukoreshwa mu ifuro ryoroshye rya polyurethane, utubumbe dukomeye twa polyurethane n'udupira two gusiga. PMDPTA ikoreshwa cyane cyane mu ifuro rya HR ry'ifuro rikonje. PMDPTA yitwa five-base di-propyleneramine, ifite uburyo bwinshi bwo gukoresha mu ifuro ryoroshye n'iry'ipfuro rikomeye. PMDPTA ishobora gutanga igisubizo cyiza cyo gutangira no gusubiza gel, kandi yongere igihe cyo gusubiza gel. Iyi catalyst ntishobora gukoreshwa yonyine gusa, ahubwo ikanakoreshwa n'izindi catalyst n'ibindi bikoresho by'inyongera. PMDPTA ishobora gushonga muri polyether polyol.

Ishongeshwa byoroshye mu bintu byinshi bishongesha. Ingano y'ibisubizo by'ifuro na gel. Ibyiza bikoreshwa mu ifuro ryoroshye, rishobora kwirinda guturika no gupfunyika kw'ifuro, rifite ubushobozi bwo kuzamura neza. Kunoza uburyo ifuro rikomeye ritunganywa, kwihanganira no gupima ubuso bwaryo. Kunoza umwobo wo hejuru wa pulasitiki yoroshye.

Imiterere y'imiterere: ubushyuhe bushyuha: 102 ° C / 1mmHg, ubucucike: 0,83 g / cm3, igipimo cyo kugarura ubushyuhe: 1.4450 kugeza 1.4480, igipimo cyo gukurura ubushyuhe: 92 ° C, igipimo cy'ubushyuhe (PKA): 9.88 ± 0.28 (Icyitonderwa). Ikoreshwa cyane cyane mu gushonga kwa alkaline, kandi ikoreshwa no mu bindi binyabutabire, nibindi, kandi ikunze gukoreshwa nk'ibitera imbaraga mu gupima no gukura amazi mu mubiri; irangi rikoreshwa hagati

Imikoreshereze ya PMDPTA

Pentamethyldipropylenetriamine ni catalyst ifite impumuro nkeya y'ifuro/gel, ishobora gukoreshwa mu gushonga ifuro ryoroheje rya polyether polyurethane, udupira dukomeye twa polyurethane, irangi, kole, nibindi, cyane cyane ikoreshwa muri Yu Cold Model HR Bubble. Ifuro irafunguye neza kandi ikoreshwa mu gushonga ifuro rya Maxfoam, ifite imikorere myiza cyane.
