Polyimide Fiber

Ulusi wa polyimide, womwe umadziwikanso kuti arylimide fiber, umatanthawuza unyolo wa molekyulu wokhala ndi ulusi wa arylimide.

Mphamvu ya ether homopexed fiber ndi 4 ~ 5cN/dtex, elongation ndi 5% ~ 7%, modulus ndi 10 ~ 12GPa, mphamvu yosungira mphamvu ndi 50% ~ 70% pambuyo pa 100h pa 300 ℃, kuchepetsa mpweya wa oxygen ndi 44, ndipo kukana kwa radiation ndikwabwino. Ulusi wa Ketone copolymerization uli ndi gawo lowoneka ngati dzenje, mphamvu 3.8cN/dtex, elongation 32%, modulus 35cN/dtex, kachulukidwe 1.41g/cm, kuchepa kwa madzi otentha ndi 250 ℃ ndi zosakwana 0.5% ndi 1%, motsatana.

Amagwiritsidwa ntchito ngati zosefera za fumbi la kutentha kwambiri, zida zamagetsi zotchinjiriza, mitundu yonse ya kutentha kwambiri komanso zovala zoteteza moto, parachute, kapangidwe ka zisa ndi zinthu zosindikizira kutentha, kulimbikitsa zinthu zophatikizika ndi anti-radiation.
