4,4'-Oxydiphthalic anhydride (ODPA) ikemikari inosiyana-siyana yepakati ine huwandu hwakawanda hwekushandisa mukugadzira zvigadzirwa zvakasiyana.ODPA cas 1823-59-2 ichena crystalline poda iyo inogadzirwa nekuita pakati pephthalic anhydride uye phenols.
4,4'-Oxydiphthalic anhydride cas 1823-59-2 inokosha yepakati mukugadzirwa kwepamusoro-soro mapolymers akadai se polyimides, polyesters, uye epoxy resins.Aya mapolymer ane akanakisa mechanic, anopisa, uye makemikari zvivakwa, zvichiita kuti abatsire mumhando dzakasiyana dzekushandisa senge aerospace, zvemagetsi, uye maindasitiri emotokari.
Polyimides ndeyepamusoro-tembiricha inodzivirira mapolymers ayo anoshandiswa mumashandisirwo anoda yakanakisa mechaniki zvivakwa.Mimwe mienzaniso yezvishandiso izvi inosanganisira mabheya, magiya, uye zvisimbiso.4,4'-Oxydiphthalic anhydride cas 1823-59-2 inokosha yepakati inoshandiswa mukugadzirwa kwepolyimides yakadai sePMDA-ODA, BPDA-ODA, uye BPDA-PDA.
Epoxy resins anoshandiswa seanonamira, machira, uye macomposites mumaindasitiri akasiyana.ODPA cas 1823-59-2inoshandiswa mukugadzira epoxy resins yakadai sebisphenol A-type epoxy resins uye novolac-type epoxy resins.Marezeni aya ane kunamatira kwakanaka, kusimba kwepamusoro, uye kusamira kwemakemikari anoita kuti akwanise kushandiswa mumaindasitiri ekuvaka, emugungwa, uye emagetsi.
Polyesters imwe mhando yepolymer inogona kugadzirwa uchishandisa ODPA seyepakati.Aya mapolymer ane simba repamusoro, kusimba, uye kuchinjika, zvichiita kuti abatsire kune dzakasiyana siyana dzekushandisa senge machira machira, zvekurongedza, uye machira.
ODPA inoshandiswawo mukugadzirwa kweplasticizers senge ortho-phthalate esters.Aya mapurasitiki anowedzerwa kumapolymers kuti awedzere kuchinjika uye kusimba.ODPA-based plasticizers ine yakanakisa yakaderera-tembiricha kuita uye inoshandiswa mumashandisirwo uko kuchinjika chinhu chakakosha.
Pamusoro pekushandiswa kwayo mukugadzirwa kwemapolymers uye plasticizers,4,4'-Oxydiphthalic anhydride cas 1823-59-2inoshandiswa semurazvo wemoto mukugadzira zvigadzirwa zvemagetsi nemagetsi.Inogona zvakare kushandiswa semuchinjiko-inobatanidza mumiriri mukugadzirwa kweanonamira, machira, uye zvimwe zvigadzirwa.
Mukupedzisa,4,4'-Oxydiphthalic anhydride cas 1823-59-2ikemikari inosiyana-siyana yepakati ine zvakawanda zvakakosha zvinoshandiswa mumaindasitiri akasiyana.Kushandiswa kwaro mukugadzira mapolymers epamusoro-soro, mapurasitiki, zvinodzosa moto, uye zvimwe zvigadzirwa zvakakonzera kufambira mberi kweminda yakawanda yetekinoroji.Nekuda kwezvimiro zvayo zvakasiyana uye akasiyana mashandisirwo, ODPA yakakosha kemikari yepakati iyo inogona kuramba ichiita basa rakakosha mukusimudzira mune ramangwana remaindasitiri akasiyana.
