4,4'-Oxydiphthalic anhydride (ODPA) iyikhemikhali ephakathi nendawo enezinhlobonhlobo zezicelo ekukhiqizeni imikhiqizo ehlukahlukene. I-ODPA cas 1823-59-2 iyimpushana emhlophe ecwebezelayo ehlanganiswa ukusabela phakathi kwe-phthalic anhydride nama-phenols.
I-4,4'-Oxydiphthalic anhydride cas 1823-59-2 iyisihluthulelo esimaphakathi ekukhiqizeni ama-polymers asebenza kahle njengama-polyimides, ama-polyester, nama-epoxy resins. Lawa ma-polymer anezakhiwo ezinhle kakhulu zemishini, ezishisayo, kanye namakhemikhali, okuwenza abe wusizo ezinhlelweni ezihlukahlukene ezifana ne-aerospace, electronics, kanye nezimboni zezimoto.
Ama-Polyimides ama-polymers amelana nokushisa okuphezulu asetshenziswa ezinhlelweni ezidinga izakhiwo ezinhle kakhulu zemishini. Ezinye izibonelo zalezi zinhlelo zokusebenza zifaka ama-bearings, amagiya, nama-seal. I-4,4'-Oxydiphthalic anhydride cas 1823-59-2 iyisiphakathi esibalulekile esisetshenziswa ekukhiqizeni ama-polyimides afana ne-PMDA-ODA, BPDA-ODA, ne-BPDA-PDA.
Ama-epoxy resins asetshenziswa njengezinto zokunamathisela, okokuhlanganisa, nezinhlanganisela ezimbonini ezahlukahlukene.I-ODPA cas 1823-59-2isetshenziswa ekukhiqizeni ama-epoxy resins njenge-bisphenol A-type epoxy resins kanye ne-novolac-type epoxy resins. Lezi zinhlaka zinokunamathela okuhle, amandla aphezulu, nokumelana namakhemikhali okuzenza zifanelekele ukusetshenziswa embonini yokwakha, yasolwandle nekagesi.
Ama-polyester angolunye uhlobo lwe-polymer olungakhiqizwa kusetshenziswa i-ODPA njengendawo ephakathi. Lawa ma-polymers anamandla aphezulu, ukuqina, kanye nokuguquguquka, okuwenza abe usizo ezinhlobonhlobo zezinhlelo zokusebenza ezifana nezintambo zendwangu, izinto zokupakisha, nezingubo zokumboza.
I-ODPA iphinde isetshenziswe ekukhiqizeni ama-plasticizer afana ne-ortho-phthalate esters. Lawa ma-plasticizers anezelwa kuma-polymers ukwandisa ukuguquguquka kwawo nokuqina. Ama-plasticizers asekelwe ku-ODPA anokusebenza okuhle kakhulu kwezinga lokushisa eliphansi futhi asetshenziselwa izinhlelo zokusebenza lapho ukuguquguquka kuyisici esibalulekile.
Ngaphezu kokusetshenziswa kwayo ekukhiqizeni ama-polymers nama-plasticizers,4,4'-Oxydiphthalic anhydride cas 1823-59-2isetshenziswa njengesinqamuleli somlilo ekukhiqizeni imikhiqizo kagesi neye-elekthronikhi. Ingasetshenziswa futhi njenge-ejenti yokuxhumanisa ekukhiqizeni okunamathelayo, okokunamathela, neminye imikhiqizo.
Ekuphetheni,4,4'-Oxydiphthalic anhydride cas 1823-59-2iyikhemikhali esezingeni eliphakathi enemisebenzi eminingi ebalulekile ezimbonini ezahlukahlukene. Ukusetshenziswa kwayo ekukhiqizeni ama-polymers asebenza kahle kakhulu, ama-plasticizers, ama-flame retardants, neminye imikhiqizo kube nomthelela ekuthuthukisweni kwezinkambu eziningi zobuchwepheshe. Ngenxa yezakhiwo zayo eziyingqayizivele kanye nezinhlelo zokusebenza ezihlukahlukene, i-ODPA iyikhemikhali ebalulekile emaphakathi okungenzeka izoqhubeka nokubamba iqhaza elibalulekile ekuthuthukisweni kwesikhathi esizayo kwezimboni ezihlukahlukene.
