4,4′-Oxydiphthalic anhydride CAS:1823-59-2

Anhydride ye4,4'-Oxydiphthalic ine mashandisirwo akasiyana-siyana mumaindasitiri akasiyana, kunyanya nekuda kwekushanda kwayo semonomer mukugadzira ma polyimide resin nemamwe ma polymer anoshanda zvakanyanya. Ma polymer aya anozivikanwa nekugadzikana kwawo kwakanyanya kwekupisa, kuramba makemikari, uye simba remakanika, zvichiita kuti akwanise kushandiswa zvakanyanya muzvikamu zvakaita semagetsi, ndege, uye kugadzira mota. Muindasitiri yemagetsi, 4,4'-oxydiphthalic anhydride inoshandiswa kugadzira zvinhu zvinodzivirira mabhodhi edunhu nezvimwe zvikamu. Kugadzikana kwekupisa kwema polymer anobva kune iyi anhydride kunoita kuti ashande zvakavimbika mumamiriro ekupisa kwakanyanya, izvo zvakakosha kumidziyo yemagetsi yemazuva ano. Uyezve, inoita basa rakakosha mukugadzirwa kwema coatings nema glues. Kubatanidzwa kwayo mumafomula kunowedzera hunhu hwekunamatira uye kugara kwenguva refu, zvichiita kuti ive yakakodzera ma coatings ekudzivirira mukuvaka uye mumaindasitiri. Ma coatings aya anopa kudzivirira ngura, makemikari, uye mamiriro ekunze akaoma. Pamusoro pezvo, 4,4'-oxydiphthalic anhydride inoshandiswa mukugadzira makemikari akakosha uye ma intermediates. Kushanda kwayo kwakasiyana kunoita kuti pave nekuumbwa kwemamorekuru akasiyana-siyana akaomarara ayo anozogadziriswazve kuita mishonga, makemikari ekurima, nemamwe makemikari akanaka. Kazhinji, hunhu hwakasiyana-siyana hwe4,4'-oxydiphthalic anhydride hunoita kuti ive chinhu chakakosha muzvinhu zvepamusoro uye mashandisirwo emaindasitiri, zvichibatsira zvikuru mukugadzirisa zvinhu zvitsva muhunyanzvi nekugadzira.
