4,4′-Oxydiphthalic anhydride CAS:1823-59-2

He maha ngā whakamahinga o te 4,4'-Oxydiphthalic anhydride puta noa i ngā ahumahi rerekē, nā tōna whai huatanga hei monomer i roto i te hanga o ngā kapia polyimide me ētahi atu polymer mahi-teitei. E mōhiotia ana ēnei polymer mō tō rātou pumau wera pai, te ātete matū, me te kaha miihini, e pai ai mō ngā tono uaua i roto i ngā rāngai pēnei i te hikohiko, te rererangi, me te hanga motuka. I roto i te umanga hikohiko, ka whakamahia te 4,4'-oxydiphthalic anhydride hei hanga rauemi whakamahana mō ngā papa ara iahiko me ētahi atu wāhanga. Mā te pumau wera o ngā polymer i ahu mai i tēnei anhydride ka taea e rātou te mahi pono i raro i ngā āhuatanga pāmahana teitei, he mea nui mō ngā taputapu hiko hou. Heoi anō, he mahi nui tāna i roto i te hanga o ngā paninga me ngā piripiri. Ko tōna whakaurunga ki roto i ngā whakatakotoranga ka whakarei ake i ngā āhuatanga piri me te roa, e pai ai mō ngā paninga tiaki i roto i ngā tono hanga me ngā tono ahumahi. Ka whakaratohia e ēnei paninga te ātete ki te waikura, ngā matū, me ngā āhuatanga taiao kino. Hei tāpiri, ka whakamahia te 4,4'-oxydiphthalic anhydride i roto i te whakatakotoranga o ngā matū motuhake me ngā takawaenga. Mā tōna kaha tauhohenga ahurei ka taea te hanga i ngā momo ngota matatini ka tukatukahia anō hei rongoā, hei matū ahuwhenua, me ētahi atu matū pai. I te nuinga, ko ngā āhuatanga kanorau o te 4,4'-oxydiphthalic anhydride he mea nui hei hanga i roto i ngā rauemi matatau me ngā tono ahumahi, ā, he mea nui ki ngā otinga auaha i roto i te hangarau me te hanga.
