Kugwiritsa polyimide filimu

Amagwiritsidwa ntchito ngati zotetezera varnish pama waya amagetsi, kapena ngati utoto wotentha kwambiri.

Zipangizo zamakono zopangira: zomwe zimagwiritsidwa ntchito popanga ndege, ndege ndi roketi, ndi imodzi mwazinthu zotentha zotentha kwambiri. Mwachitsanzo, dongosolo la ndege la supersonic linapanga liwiro la 2.4M, kutentha kwa pamwamba pa 177 ° C panthawi ya ndege, ndi moyo wofunikira wa maola 60,000. Malinga ndi malipoti, 50% ya zida zomangika zatsimikiziridwa kuti ndi kaboni fiber yokhala ndi thermoplastic polyimide monga matrix resin. Zolimbikitsidwa zophatikizika, kuchuluka kwa ndege iliyonse ndi pafupifupi 30t.

CHIKWANGWANI: Modulus of elasticity ndiyachiwiri kwa kaboni fiber. Amagwiritsidwa ntchito ngati fyuluta yazinthu zotentha kwambiri ndi zida zamagetsi komanso zotchinga zipolopolo komanso zopanda moto. Zinthu zosiyanasiyana za polyimide zimapangidwa ku Changchun, China.

Thovu la pulasitiki: limagwiritsidwa ntchito ngati zinthu zosagwira kutentha ndi kutentha.

Mapulasitiki aumisiri: Pali ma thermosets ndi thermoplastics. Thermoplastics imatha kupangidwa ndi kuponderezedwa kapena kupangidwa jekeseni kapena kusamutsa. Amagwiritsidwa ntchito kwambiri podzipaka mafuta, kusindikiza, kutsekereza ndi zida zamapangidwe. Zida za Guangcheng polyimide zayamba kugwiritsidwa ntchito pazigawo zamakina monga kompresa rotor, mphete za pistoni ndi zisindikizo zapadera zapampu.

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

Zomwe zili pamwambazi ndi kugwiritsa ntchito kanema wa polyimide mufilimu, yomwe ingathandize kumvetsetsa kanema wa polyimide.
