4,4'-Oxydiphthalic anhydride (ODPA) yimichiza ephakathi enezinto ezininzi ezinoluhlu olubanzi lwezicelo kwimveliso yeemveliso ezahlukeneyo.I-ODPA cas 1823-59-2 ngumgubo omhlophe we-crystalline owenziwe ngokuphendula phakathi kwe-phthalic anhydride kunye ne-phenols.
I-4,4'-Oxydiphthalic anhydride cas 1823-59-2 yinto ephambili ephakathi kwimveliso yeepolymers eziphezulu zokusebenza ezifana ne-polyimides, i-polyesters, kunye ne-epoxy resins.Ezi polima zineepropathi ezigqwesileyo zoomatshini, ezishushu, kunye neekhemikhali, zibenza babe luncedo kwiinkqubo ezahlukeneyo ezifana ne-aerospace, i-electronics, kunye nemizi-mveliso yeemoto.
Iipolyimides ziipolima ezinobushushu obuphezulu ezisetyenziswa kwizicelo ezifuna iipropathi ezigqwesileyo zoomatshini.Eminye imizekelo yezi zicelo ibandakanya iibheringi, iigiya, kunye netywina.I-4,4'-Oxydiphthalic anhydride cas 1823-59-2 yinto ebalulekileyo ephakathi esetyenziselwa ukuveliswa kweepolyimides ezifana ne-PMDA-ODA, BPDA-ODA, kunye ne-BPDA-PDA.
I-epoxy resins isetyenziswa njengezinto zokuncamathelisa, zokugquma, kunye ne-composites kumashishini ahlukeneyo.I-ODPA cas 1823-59-2isetyenziselwa ukuveliswa kwee-epoxy resins ezifana ne-bisphenol A-type epoxy resins kunye ne-novolac-type epoxy resins.Ezi ntlaka zincamathele kakuhle, zomelele kakhulu, kwaye zikwazi ukumelana neekhemikhali ezizenza zilungele ukusetyenziswa kushishino lokwakha, lwaselwandle nolwezombane.
Iipolyester lolunye uhlobo lwepolymer olunokuveliswa kusetyenziswa i-ODPA njengendawo ephakathi.Ezi polima zinamandla aphezulu, ukuqina, kunye nokuguquguquka, zizenza zibe luncedo kuluhlu olubanzi lwezicelo ezinje ngeentsinga zelaphu, izinto zokupakisha, kunye neengubo.
I-ODPA ikwasetyenziselwa ukuveliswa kweeplastiki ezifana ne-ortho-phthalate esters.Ezi plasticizers zongezwa kwiipolymers ukwandisa ukuguquguquka kwazo kunye nokuqina.Iiplasticizers ezisekelwe kwi-ODPA zinomsebenzi obalaseleyo wobushushu obuphantsi kwaye zisetyenziselwa izicelo apho ukuguquguquka kuyinto ebalulekileyo.
Ukongeza kokusetyenziswa kwayo kwimveliso yeepolymers kunye neplastiki,4,4'-Oxydiphthalic anhydride cas 1823-59-2isetyenziswa njengesithinteli somlilo kwimveliso yeemveliso zombane neze-elektroniki.Isenokusetyenziswa njenge-agent edibanisayo ekuveliseni izinto zokuncamathelisa, iingubo kunye nezinye iimveliso.
Ukuququmbela,4,4'-Oxydiphthalic anhydride cas 1823-59-2yikhemikhali ephakathi enemisebenzi emininzi ebalulekileyo kumashishini ahlukeneyo.Ukusetyenziswa kwayo ekuveliseni iipolymers ezisebenza kakhulu, iiplasticizers, i-flame retardants, kunye nezinye iimveliso kube negalelo ekuphuculweni kweenkalo ezininzi zobuchwepheshe.Ngenxa yeepropati zayo ezizodwa kunye nezicelo ezahlukeneyo, i-ODPA yikhemikhali ebalulekileyo ephakathi enokuthi iqhubeke idlala indima ebalulekileyo kuphuhliso lwexesha elizayo lwamashishini ahlukeneyo.
