Xav paub dab tsi yog daim ntawv thov ntawm polyimide zaj duab xis? Saib cov no

Polyimide zaj duab xis yog ib qho ntawm cov khoom lag luam thaum ntxov ntawm polyimide, siv rau qhov rwb thaiv tsev ntawm cov motors thiab cable wrapping cov ntaub ntawv. Cov khoom tseem ceeb yog DuPont Kapton, Ube Industries ‘Upilex series thiab Zhongyuan Apical.

Lub pob tshab polyimide zaj duab xis tuaj yeem siv los ua lub hnub ci hloov pauv ntawm lub hauv paus phaj. IKAROS sails yog ua los ntawm polyimide films thiab fibers. Polyimide fibers tuaj yeem siv los lim cov roj cua kub, thiab cov xov paj polyimide tuaj yeem cais cov plua plav thiab cov tshuaj tshwj xeeb los ntawm cov pa tawm.

1. Xim: Siv los ua cov xim pleev xim rau cov hlau nplaum hlau, los yog cov xim kub resistant.

2. Cov ntaub ntawv zoo tshaj plaws: siv hauv aerospace, aircraft thiab foob pob hluav taws. Nws yog ib qho ntawm cov khoom siv hluav taws xob kub resistant. Piv txwv li, US cov kev pab cuam supersonic neeg nrog caij dav hlau tsim ib qhov ceev ntawm 2.4M, qhov kub thiab txias ntawm 177 ° C thaum lub sij hawm ya davhlau, thiab lub neej kev pab cuam ntawm 60,000 teev. Raws li cov lus ceeb toom, 50% ntawm cov khoom siv tau raug txiav txim siab los ntawm cov thermoplastic polyimide resin. Tus nqi ntawm carbon fiber reinforced composite cov ntaub ntawv rau txhua lub dav hlau yog li 30t.

3. Fiber: Modulus ntawm elasticity yog thib ob tsuas yog carbon fiber. Nws yog siv los ua cov khoom siv lim dej rau cov xov xwm kub kub thiab cov khoom siv hluav taws xob thiab cov mos txwv thiab cov ntaub thaiv hluav taws. Ntau yam khoom siv polyimide yog tsim nyob rau hauv Changchun, Tuam Tshoj.

4, ua npuas ncauj yas: siv los ua cov khoom siv hluav taws xob kub kub.

5. Engineering plastics: Muaj cov thermosetting thiab thermoplastic hom. Cov thermoplastic hom tuaj yeem yog compression molded lossis txhaj tshuaj molded lossis hloov molded. Feem ntau yog siv rau nws tus kheej lubricating, sealing, insulating thiab cov khoom siv. Guangcheng polyimide cov ntaub ntawv tau pib siv rau txhua yam khoom xws li compressor rotors, piston rings thiab tshwj xeeb twj tso kua mis seals.

6. Separation membrane: Siv rau kev sib cais ntawm ntau yam pa pa, xws li hydrogen / nitrogen, nitrogen / oxygen, carbon dioxide / nitrogen los yog methane, kom tshem tawm cov dej noo ntawm huab cua hydrocarbon pub roj thiab cawv. Nws kuj tseem siv tau ua pervaporation membrane thiab ultrafiltration membrane. Vim nws qhov kub thiab txias tsis kam rau cov kuab tshuaj organic, polyimide yog qhov tseem ceeb tshwj xeeb hauv kev sib cais ntawm cov organic gases thiab kua.
