Niki Pyromellitis Dianhydride hamwe na CAS 89-32-7?

Dianhydride ya pyromellitike (mu magambo ahinnye yiswe PMDA), ikoreshwa cyane cyane muguhuza polyimide, kubera ko polyimide ifite imbaraga zidasanzwe zo kurwanya ubushyuhe bukabije, aside na alkali irwanya, bihebuje Kubera imiterere yubukanishi, imiterere y’amashanyarazi no guhagarara neza, ikoreshwa cyane mu buhanga buhanitse nko mu ndege, mu kirere, mu kirere cya elegitoroniki ndetse n’ibikoresho bya atome, bifite ingufu zikomeye.

Gusaba

Pyromellitis dianhydride (PMDA) ni ibikoresho byingenzi mu nganda ngengabihe, hamwe n’ibikoresho fatizo bigamije iterambere ry’ibikoresho bishya bya shimi n’ibicuruzwa byiza byongerewe agaciro. Ikoreshwa cyane cyane mubikorwa bya polyimide monomers, kandi irashobora no gukoreshwa nkumuti ukiza kuri epoxy resin hamwe nu muti uhuza imiti ya polyester, ikoreshwa mugukora irangi ry'ubururu bwa phthalocyanine nibindi bikomokaho, nibindi, kandi bifite uburyo bwinshi bwo gukoresha. Pyromellitis dianhydride, izwi kandi nka homoanhydride, ifite imiterere yihariye ya molekile kandi irashobora gukoreshwa mugukora ibikoresho birwanya ubushyuhe, insimburangingo y’amashanyarazi hamwe n’imiti irwanya imiti, muri byo hakoreshwa cyane ni nka monolayeri ya polyimide. Ihujwe na diamine ya aromatic kugirango ibone plastiki ya polyimide, ariko ubuziranenge bwa pyromellitis dianhydride ni ndende cyane, bugomba kuba burenga 99%.
