Kusanthula Mwachidule kwa Kugwiritsa Ntchito Mwanzeru kwa Mafilimu a Polyimide

Filimu ya Polyimide ndi imodzi mwazinthu zakale kwambiri za polyimide, zomwe zimagwiritsidwa ntchito popanga ma motors ndi zida zomata chingwe. Zogulitsa zazikulu ndi DuPont Kapton, Ube’s Upilex series ndi Zhongyuan Apical. Makanema a Transparent polyimide amagwira ntchito ngati ma cell a solar osinthika. Matanga a IKAROS amapangidwa ndi mafilimu a polyimide ndi ulusi. M’gawo lopangira mphamvu zamagetsi, ulusi wa polyimide ukhoza kugwiritsidwa ntchito kusefa mpweya wotentha, ndipo ulusi wa polyimide ukhoza kulekanitsa fumbi ndi zinthu zapadera za Chemical.

Kupaka: Monga insulating utoto wa waya maginito, kapena ngati kutentha kugonjetsedwa ndi utoto.

Zida zophatikizika zapamwamba: zomwe zimagwiritsidwa ntchito muzamlengalenga, ndege ndi zida za roketi. Ndi imodzi mwazinthu zomangika zomwe zimalimbana ndi kutentha kwambiri. Mwachitsanzo, ndege yonyamula anthu yapamwamba kwambiri ku United States idapangidwa kuti ikhale ndi liwiro la 2.4M, kutentha kwapamtunda kwa 177 ° C pakuuluka, komanso moyo wofunikira wa 60,000h. Akuti 50% ya zida zomangira zatsimikiziridwa kuti ndi thermoplastic polyimide ngati utomoni wa matrix. wa carbon CHIKWANGWANI analimbitsa gulu zipangizo, kuchuluka kwa ndege iliyonse ndi za 30t.

Fiber: The modulus of elasticity ndi yachiwiri ku carbon fiber, yomwe imagwiritsidwa ntchito ngati fyuluta ya zinthu zotentha kwambiri komanso zinthu zotulutsa ma radio, komanso nsalu zoteteza zipolopolo ndi zosatentha moto. Mitundu yosiyanasiyana ya polyimide imapangidwa ku Changchun, China.

Pulasitiki ya thovu: imagwiritsidwa ntchito ngati zida zotchingira kutentha kwambiri.

Mapulasitiki aumisiri: Pali ma thermosets ndi thermoplastics. Thermoplastics imatha kuumbidwa kapena kupangidwa jekeseni kapena kusamutsa. Amagwiritsidwa ntchito kwambiri podzipaka mafuta, kusindikiza, zotetezera ndi zomangamanga. Zida za Guangcheng polyimide zakhala zikugwiritsidwa ntchito pamakina monga ma compressor rotary vanes, mphete za piston ndi zisindikizo zapadera zapampu.

Nembanemba wolekanitsa: amagwiritsidwa ntchito polekanitsa mitundu yosiyanasiyana ya gasi, monga haidrojeni/nitrogen, nayitrogeni/oxygen, carbon dioxide/nitrogen kapena methane, ndi zina zotero, kuchotsa chinyontho mu mpweya wa mpweya wa hydrocarbon ndi mowa. Itha kugwiritsidwanso ntchito ngati nembanemba ya pervaporation ndi nembanemba ya ultrafiltration. Chifukwa cha kukana kutentha ndi kukana kwa organic zosungunulira za polyimide, ndizofunika kwambiri pakulekanitsa mpweya wachilengedwe ndi zakumwa.
