4,4′-(hexafluoroisopropylidene)diphthalicanhydride CAS:1107-00-2

4,4'- (Hexafluoroisopropylidene) diphthalic anhydride imagwiritsidwa ntchito kwambiri popanga ma polima ogwira ntchito kwambiri komanso zinthu zapadera chifukwa cha mawonekedwe ake apadera a mankhwala. Mu chemistry ya polima, imagwiritsidwa ntchito ngati maziko ofunikira popanga ma polyimides, omwe amadziwika kuti ndi olimba kwambiri pa kutentha, mphamvu zamakanika, komanso kukana mankhwala. Ma polyimides awa amagwiritsidwa ntchito kwambiri m'mafakitale opanga ndege, zamagetsi, ndi magalimoto popanga zinthu zomwe zimafuna kugwira ntchito bwino kwambiri pansi pa mikhalidwe yovuta yogwirira ntchito. Kuphatikiza apo, mankhwalawa amagwiritsidwa ntchito popanga zokutira zapadera ndi mafilimu okhala ndi mphamvu zoteteza kutentha komanso zotchinga. Zophimba izi zimagwiritsidwa ntchito m'magawo oteteza zida zamagetsi, zokutira zoteteza dzimbiri pazida zamafakitale, ndi zinthu zoteteza kutentha kwambiri. Kuphatikiza apo, 4,4'- (Hexafluoroisopropylidene) diphthalic anhydride imathandizira kupanga zida zapamwamba zophatikizika zomwe zimagwiritsidwa ntchito mu ntchito zapamlengalenga ndi chitetezo. Kuphatikizidwa kwake mu matrix ophatikizika kumawonjezera kukhazikika kwawo pa kutentha, mphamvu zoletsa moto, komanso kulimba konse, zomwe zimapangitsa kuti zikhale zoyenera zofunikira pakupanga ndi kugwira ntchito m'ndege, zombo zamlengalenga, ndi zida zankhondo. Kuphatikiza apo, mankhwalawa amagwira ntchito yofunika kwambiri popanga zomatira zapadera ndi zomatira zomwe zimapereka mphamvu yabwino kwambiri yolumikizira komanso kukana kutentha kwambiri, mankhwala, komanso kupsinjika kwa chilengedwe. Zomatirazi zimathandiza kwambiri popanga zinthu zofunika kwambiri m'mafakitale amagetsi, magalimoto, ndi zida zamankhwala komwe kudalirika ndi magwiridwe antchito ndizofunikira kwambiri. Mwachidule, 4,4'-(Hexafluoroisopropylidene)diphthalic anhydride imagwira ntchito ngati maziko opangira ma polima apamwamba, zokutira zapadera, zinthu zophatikizika, ndi zomatira zokhala ndi kukhazikika kwa kutentha, mphamvu zamakanika, komanso kukana mankhwala. Kugwiritsa ntchito kwake mosiyanasiyana kumathandizira kupititsa patsogolo magawo osiyanasiyana amafakitale, zomwe zimathandiza kupanga zipangizo zatsopano zomwe zimagwirizana ndi zosowa zaukadaulo komanso zogwirira ntchito.
