Mukufuna kudziwa momwe filimu ya polyimide imagwirira ntchito? Yang’anani pa izi

Filimu ya Polyimide ndi imodzi mwazinthu zoyambirira za polyimide, zomwe zimagwiritsidwa ntchito popanga ma motors ndi zida zomata chingwe. Zogulitsa zazikulu ndi DuPont Kapton, Ube Industries ‘Upilex series ndi Zhongyuan Apical.

Kanema wowonekera wa polyimide atha kugwiritsidwa ntchito ngati mbale yosinthika ya solar cell base. Matanga a IKAROS amapangidwa ndi mafilimu a polyimide ndi ulusi. Ulusi wa polyimide ukhoza kugwiritsidwa ntchito kusefa mpweya wotentha, ndipo ulusi wa polyimide ungalekanitse fumbi ndi mankhwala apadera ndi mpweya wotuluka.

1. Utoto: Amagwiritsidwa ntchito ngati insulating penti wa waya maginito, kapena ngati kutentha kupirira penti.

2. Zida zophatikizika zapamwamba: zomwe zimagwiritsidwa ntchito muzamlengalenga, ndege ndi zida za roketi. Ichi ndi chimodzi mwa zinthu zomangika zosagwira kutentha kwambiri. Mwachitsanzo, pulogalamu ya ndege zonyamula anthu zamphamvu kwambiri ku US inapanga liwiro la 2.4M, kutentha pamwamba pa 177°C pakuuluka, ndi moyo wofunikira wa maola 60,000. Malinga ndi malipoti, 50% ya zida zomangika zatsimikiziridwa kuti zimachokera ku thermoplastic polyimide resin. Kuchuluka kwa carbon fiber kulimbikitsa zida zophatikizika pa ndege iliyonse ndi pafupifupi 30t.

3. Fiber: The modulus of elasticity ndi yachiwiri ku carbon fiber. Amagwiritsidwa ntchito ngati zinthu zosefera pazambiri zotentha kwambiri komanso zida zotulutsa ma radio ndi nsalu zoteteza zipolopolo komanso zosawotcha moto. Mitundu yosiyanasiyana ya polyimide imapangidwa ku Changchun, China.

4, thovu pulasitiki: ntchito monga kutentha kutentha kutchinjiriza zakuthupi.

5. Mapulasitiki a Engineering: Pali mitundu ya thermosetting ndi thermoplastic. Mitundu ya thermoplastic imatha kuumbidwa kapena kupangidwa ndi jakisoni kapena kusamutsa. Amagwiritsidwa ntchito kwambiri podzipaka mafuta, kusindikiza, zotetezera ndi zomangamanga. Zida za Guangcheng polyimide zayamba kugwiritsidwa ntchito pazigawo zamakina monga kompresa rotor, mphete za pistoni ndi zisindikizo zapadera zapampu.

6. Nembanemba wolekanitsa: Amagwiritsidwa ntchito pakulekanitsa mitundu yosiyanasiyana ya gasi, monga haidrojeni/nitrogen, nayitrogeni/oxygen, carbon dioxide/nitrogen kapena methane, kuchotsa chinyezi ku mpweya wa hydrocarbon feed gasi ndi mowa. Itha kugwiritsidwanso ntchito ngati nembanemba ya pervaporation ndi nembanemba ya ultrafiltration. Chifukwa cha kukana kwake kutentha ndi kukana zosungunulira organic, polyimide ndi yofunika kwambiri pa kulekana kwa organic mpweya ndi zakumwa.
