Pyromellitic dianhydridecas2420-87-3: "Ihhashi elimnyama" emkhakheni wezinto ezintsha zamakhemikhali ziheha ukunakwa komkhakha

Muva nje, phakathi kokuthuthukiswa okukhulayo kwemboni yamakhemikhali, i-pyromellitic dianhydride (PMDA), i-compound ebalulekile, uthule buthule ekubumbeni izinto eziningi eziphakeme kakhulu futhi kubangele igagasi elisha lokuhlola kulo lonke imbonini embonini, i-academia, kanye nemiphakathi yocwaningo.

Njengento ebalulekile ye-organic yamakhemikhali eluhlaza, i-pyromellitic mianhydride ingahle ibonakale ingadingekile ekuqaleni kokuqala, kepha empeleni inamakhono ahlukile. Ngokohlangothini lokukhiqizwa, amabhizinisi amaningi asekhaya aqinisa imizamo yawo yokuthuthukisa futhi anwebe imigqa yawo yokukhiqiza. [Igama lenkampani] I-Chemical Co, Ltd. Usanda kuqeda ukusebenza kahle nokuthuthuka kwenqubo yokukhiqiza ye-promellitic dianhydride. Ubuchwepheshe obusha bamukela uhlelo lokulawula oluhlakaniphile olulawula kahle amapharamitha asemqoka anjengezinga lokushisa lokuphendula kanye nengcindezi. Lokhu kukhuphule ukuhlanzeka komkhiqizo ngamaphesenti ama-3 amaphesenti futhi kunciphise kakhulu okuqukethwe kokungcola. Akugcini ngokuqinisekisa ukuqina kwekhwalithi elandelayo kodwa futhi kuthuthukisa kakhulu ukusebenza kahle kokukhiqiza, ngokukhipha isikhathi ngeyunithi ngayinye kukhuphuka ngamaphesenti angaphezu kuka-20%, kunikeza inkampani inzuzo yokuqala emakethe yokuncintisana kakhulu.

Ensimini yesicelo, i-pyromellitic mianhydride ikhanya kakhulu. Amaqembu ocwaningo ahlala ehlola amandla alo ekwakhiweni kwezinto ezisebenza kahle. Ngokuya kwezinto zokwenziwa nge-elekthronikhi, amafilimu e-polymide ahlanganiswe nawo anengxenye yendabuko yendabuko yokufaka amavolumu, kepha i-voltectric syctipting njalo, ne-chips ephelele yokushisa, ama-chips okunembe ama-5G kanye namadivayisi wokuxhumana wesikhathi esizayo. Ibhizinisi eliholayo lobuchwepheshe le-elekthronikhi lifinyelele ngokubambisana kwamasu nabahlinzeki bezinto ezibonakalayo abasezingeni eliphezulu futhi bathathe umthofu ekuhlolweni kwemikhiqizo yokufaka i-chip efakwe kwimikhiqizo entsha ye-polyimide, umncintiswano wemikhiqizo yezobuchwepheshe yezokuxhumana ngesizukulwane esilandelayo.

Umkhakha we-Aerospace ubuye futhi akalimalanga ngemuva. Ngenxa yezakhiwo ezishisa kakhulu nezindawo zokuvimbela izinto ezivinjelwe kusuka ku-Pyromellitic Dianhydride, kusetshenziselwa amapulasitiki wobunjiniyela afanele ukukhiqiza izingxenye ezilula zokuvikela ezingasindi emaphethelweni amaphiko ezindiza. Uma kuqhathaniswa nezakhi zensimbi yendabuko, zinciphisa isisindo ngaphezulu kwama-30%, ukusika kabi uphethiloli kanye nokusiza izimoto ze-aerospace zindiza kakhulu futhi zisheshe. Ngaphezu kwalokho, lapho izinto zokwenziwa ezivela kule nto zifakwa ezingxenyeni ezikhethekile zokuvikela zezintambo ezikhethekile zezindawo zesikhala, zingamelana nemisebe ye-cosmic ngokweqile, ziqinisekisa ukuhanjiswa kwedatha okuzinzile phakathi kwemishini yendawo eyinkimbinkimbi.
