4,4'-Oxydiphthalic anhydride (ODPA) he mea hoʻohui kemika maʻamau i loaʻa i ka laulā o nā noi i ka hana ʻana i nā huahana like ʻole.ʻO ka ODPA cas 1823-59-2 he pauka keʻokeʻo keʻokeʻo i hoʻohui ʻia e ka hopena ma waena o ka phthalic anhydride a me nā phenols.
ʻO 4,4'-Oxydiphthalic anhydride cas 1823-59-2 he mea koʻikoʻi ia i ka hana ʻana i nā polymers kiʻekiʻe e like me nā polyimides, polyesters, a me nā resins epoxy.Loaʻa i kēia mau polymers nā waiwai mechanical, thermal, a me kemika maikaʻi loa, e hoʻohana pono ai i nā ʻano hana like ʻole e like me ka aerospace, electronics, a me nā ʻoihana automotive.
ʻO nā polyimides nā polymers kūpaʻa kiʻekiʻe i hoʻohana ʻia i nā noi e pono ai nā waiwai mechanical maikaʻi loa.ʻO kekahi mau hiʻohiʻona o kēia mau noi e pili ana i nā bearings, gears, a me nā sila.ʻO 4,4'-Oxydiphthalic anhydride cas 1823-59-2 he mea koʻikoʻi ia i hoʻohana ʻia i ka hana ʻana i nā polyimides e like me PMDA-ODA, BPDA-ODA, a me BPDA-PDA.
Hoʻohana ʻia nā resins epoxy e like me nā adhesives, coatings, a composites i nā ʻoihana like ʻole.ODPA cas 1823-59-2hoʻohana ʻia i ka hana ʻana i nā resins epoxy e like me ka bisphenol A-type epoxy resins a me ka novolac-type epoxy resins.Loaʻa i kēia mau resins ka hoʻopili maikaʻi ʻana, ka ikaika kiʻekiʻe, a me ke kūpaʻa kemika e kūpono iā lākou no ka hoʻohana ʻana i ke kūkulu ʻana, kai, a me nā ʻoihana uila.
ʻO nā polyesters kekahi ʻano polymer i hiki ke hana ʻia me ka hoʻohana ʻana i ka ODPA ma ke ʻano he waena.Loaʻa i kēia mau polymers ka ikaika kiʻekiʻe, ka lōʻihi, a me ka maʻalahi, e hoʻohana pono iā lākou no ka nui o nā noi e like me nā fiber textile, nā mea hoʻopihapiha, a me nā uhi.
Hoʻohana ʻia ʻo ODPA i ka hana ʻana i nā plasticizers e like me nā ortho-phthalate esters.Hoʻohui ʻia kēia mau plasticizer i nā polymers e hoʻonui i ko lākou maʻalahi a me ka lōʻihi.ʻO nā plasticizers hoʻokumu i ka ODPA he hana haʻahaʻa haʻahaʻa maikaʻi loa a hoʻohana ʻia i nā noi kahi mea koʻikoʻi ka maʻalahi.
Ma kahi o kona hoʻohana ʻana i ka hana ʻana i nā polymers a me nā plasticizers,4,4'-Oxydiphthalic anhydride cas 1823-59-2hoʻohana ʻia ma ke ʻano he lapalapa ahi i ka hana ʻana i nā huahana uila a me ka uila.Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻopili cross-linking i ka hana ʻana i nā adhesives, coatings, a me nā huahana ʻē aʻe.
I ka hopena,4,4'-Oxydiphthalic anhydride cas 1823-59-2he mea hoʻohana kemika maʻamau i loaʻa nā noi nui i nā ʻoihana like ʻole.ʻO kona hoʻohana ʻana i ka hana ʻana i nā polymers kiʻekiʻe, plasticizers, flame retardants, a me nā huahana ʻē aʻe i kōkua i ka holomua o nā ʻano ʻenehana he nui.Ma muli o kāna mau waiwai kū hoʻokahi a me nā noi like ʻole, ʻo ODPA kahi mea koʻikoʻi koʻikoʻi kemika e hoʻomau i ka hana nui i ka hoʻomohala ʻana o nā ʻoihana like ʻole.
