I-4,4' -'-oxydipho ye-anhydride (odpa) Ngaba ikhemikhali eguquguqukayo iphakathi kuluhlu olubanzi lwezicelo ekuvelisweni kweemveliso ezahlukeneyo. I-Odpa cas 1823-59-2 yipoder emhlophe ye-crystalline entywila ngokuphendula phakathi kwe-PHTHAY i-anhydride kunye ne-phenols.
4,4'-Oxydiphthalic anhydride cas 1823-59-2 is a key intermediate in the production of high-performance polymers such as polyimides, polyesters, and epoxy resins. Ezi polymers zineempawu ezigqwesileyo, i-thermal, kunye neekhemikhali, zibenza zibe ziluncedo kwizicelo ezahlukeneyo ezinje nge-aerospace, i-elektroniki, kunye nemizi-mveliso yemoto.
I-polyomides i-polymers enganyangekiyo esetyenziswa kwizicelo ezifuna iipropathi ezifanelekileyo. Eminye imizekelo yezi zicelo ibandakanya iibherithi, iigiya kunye namatywina. I-4,4'--'--'-'-i-Oxydipho ye-Anhydride Das 1823-59-2 sisiseko esisetyenzisiweyo kwimveliso ye-poldaimenis enje nge-PMDA-oda, i-BPDA-PDA-PDA.
I-Epoxy Reward isetyenziswa njengabahambi, iingubo, kunye neziqu ezikumveliso wamashishini ohlukeneyo.I-Odpa cas 1823-59-2isetyenziselwa ukuveliswa kwe-Epoxy Redins efana ne-bisphenol ye-bisphenol ye-epoxy ye-epoxy kunye ne-novolac-uhlobo lwe-iposmes. Le mihlali inomlinganiso olungileyo, amandla aphezulu, kunye nokuxhathisa amachiza okwenza ukuba balungele ukusetyenziswa kulwakhiwo, elwandle, kunye nombane.
I-Polysters lolunye uhlobo lwepolymer enokuveliswa usebenzisa i-Odpa njengelinye eliphakathi. Ezi polimers zinamandla aphezulu, ukuqina, kunye nokuguquguquka, zibenza ziluncedo kuluhlu olubanzi lwezicelo ezinje ngemingxunya ye-letles, izixhobo zokupakisha, kunye neengubo.
I-OdPA ikwasetyenziswa kwimveliso yamaphatho-e-ortho-Phthalate Esters. Ezi ziphangiyeyi zongezwa kwi-polymers ukonyusa ukuguquguquka kwabo kunye nokuqina. Iiplastiki ezisekwe kwi-OdPA zilungelelaniswe kakuhle kakhulu kwaye zisetyenziswa kwizicelo apho bhetyebhetye yinto ebaluleke kakhulu.
Ukongeza kusetyenziso lwayo ekuvelisweni kwee-polymers kunye neeplasitizeli,I-4,4' -'-i-oxydiphisetyenziswa njengelangatye ekuhlawulelo kwimveliso yeemveliso zombane kunye ne-elektroniki. Ingasetyenziswa njenge-arhente yokunxibelelanisa umnqamlezo ekuvelisweni kweedeshers, iingubo, kunye nezinye iimveliso.
Ukuququmbela,I-4,4' -'-i-oxydiphNgaba ikhemizemikhali eguquguqukayo iphakathi kwezicelo ezininzi ezibalulekileyo kumashishini ahlukeneyo. Ukusetyenziswa kwayo kwimveliso yee-polymers eziphezulu, iiplasitizeli, ukuziphindezela, kunye nezinye iimveliso kube negalelo ekuqhubeni phambili amabakala amaninzi obuchwephesha. Ngenxa yepropathi yayo eyahlukileyo kunye nezicelo ezahlukeneyo, i-Odpa yikhemikhali ebalulekileyo ephakathi apho kunokwenzeka ukuba aqhubeke nokudlala indima ebalulekileyo kuphuhliso lwamashishini ngamaxesha onke.
