4,4′-(hexafluoroisopropylidene)diphthalicanhydride CAS:1107-00-2

He nui te whakamahinga o te 4,4'-(Hexafluoroisopropylidene)diphthalic anhydride i roto i te hanganga o ngā polymer mahi-teitei me ngā rauemi motuhake nā ōna āhuatanga matū ahurei. I roto i te matū polymer, he poraka hanga matua mō te hanga polyimides, e rongonui ana mō tōna pumau wera, kaha miihini, me te ātete matū. He whānuitia te whakamahinga o ēnei polyimides i roto i ngā ahumahi rererangi, hikohiko, me te motuka mō te hanga wāhanga e hiahia ana ki te mahi pai ake i raro i ngā āhuatanga mahi uaua. Hei tāpiri, ka whakamahia tēnei matū i roto i te whanaketanga o ngā paninga me ngā kiriata motuhake me te ātete wera me ngā āhuatanga ārai tino pai. Ka kitea ngā tono o ēnei paninga i roto i ngā paparanga tiaki mō ngā taputapu hiko, ngā paninga ātete-waikura mō ngā taputapu ahumahi, me ngā rauemi whakamahana pāmahana-teitei. Hei tāpiri, ka whai wāhi te 4,4'-(Hexafluoroisopropylidene)diphthalic anhydride ki te hanga rauemi hiato matatau e whakamahia ana i roto i ngā tono rererangi me te tiaki. Ko tōna whakaurunga ki ngā matrices hiato ka whakarei ake i tōna pumau wera, ōna āhuatanga ātete-mura, me te roa whānui, ka pai ai mō ngā whakaritenga hanganga me ngā mahi uaua i roto i ngā waka rererangi, ngā waka mokowhiti, me ngā taputapu hōia. Hei tāpiritanga, he mahi nui tā tēnei matū i roto i te hanganga o ngā piripiri me ngā hiri motuhake e tuku ana i te kaha piri pai me te ātete ki ngā pāmahana tino kino, ngā matū, me te ahotea taiao. Ka kitea te whai huatanga o ēnei piripiri i roto i te whakakotahi i ngā wāhanga nui i roto i ngā ahumahi hiko, motuka, me ngā taputapu hauora e tino hira ana te pono me te mahi. Hei whakarāpopototanga, ko te 4,4'-(Hexafluoroisopropylidene)diphthalic anhydride he poraka hanga taketake mō te hanga i ngā polymer mahi-teitei, ngā paninga motuhake, ngā rauemi hiato, me ngā piripiri me te pumau wera tino pai, te kaha miihini, me te ātete matū. Ko ōna tono maha e whai wāhi ana ki te whakatairanga i ngā momo rāngai ahumahi, e āhei ai te whakawhanake i ngā rauemi auaha kua whakaritea mō ngā hiahia hangarau me ngā hiahia whakahaere.
