Mea Hana Kumukūʻai Maikaʻi Pentamethyldipropylenetriamine (PMDPTA) CAS: 3855-32-1

wehewehe pōkole:

He mea hoʻonui kaulike huʻa/gel ʻala haʻahaʻa ka PMDPTA, hiki ke hoʻohana ʻia i loko o ka huʻa palupalu polyurethane ʻano polyether, nā pehu paʻakikī polyurethane a me nā mea hoʻopili uhi. Hoʻohana kūikawā ʻia ka PMDPTA i ka huʻa HR mold anu. Ua kapa ʻia ʻo PMDPTA he ʻelima-kumu di-propyleneramine, nona ka laulā o nā noi i nā huʻa palupalu a paʻakikī like ʻole. Hiki i ka PMDPTA ke hāʻawi i kahi pane hoʻomaka kaulike a me ka pane gel, a hoʻolōʻihi i ka manawa pane huʻa a me ka gel. ʻAʻole hiki ke hoʻohana wale ʻia kēia mea hoʻonui, akā kaʻana like pū me nā mea hoʻonui ʻē aʻe a me nā mea kōkua. Hiki ke hoʻoheheʻe ʻia ka PMDPTA i loko o ka polyether polyol.

He maʻalahi ia e hoʻoheheʻe ʻia i ka hapa nui o nā mea hoʻoheheʻe. Kaulike ka hopena huʻa a me ka gel. Hoʻohana ʻia nā pono i ka huʻa poloka palupalu, hiki ke pale aku i ka nahā a me ka pinhole o ka huʻa, kahi hana hoʻokiʻekiʻe maikaʻi loa. Hoʻomaikaʻi i ka hiki ke hana ʻia, ke ahonui a me ka hana hoʻōla ʻili o ka huʻa paʻakikī. Hoʻomaikaʻi i ka lua kiʻekiʻe o ka plastik huʻa palupalu.

Nā waiwai waiwai: kiko paila: 102 ° C / 1mmHg, density: 0,83 g / cm3, index refractive: 1.4450 a i 1.4480, kiko flash: 92 ° C, coefficient acidity (PKA): 9.88 ± 0.28 (Wānana). Hoʻohana nui ʻia ia no nā phenols hoʻoheheʻe alkaline, a hoʻohana pū ʻia no nā inter -phenylphenols, a pēlā aku, a hoʻohana pinepine ʻia ma ke ʻano he catalysts i nā hopena esterization a me dehydration; dye intermediate
