Polyimide Fiber ntau

Polyimide fiber, tseem hu ua arylimide fiber, hais txog cov saw molecular uas muaj arylimide fiber.

Lub zog ntawm ether homopexed fiber ntau yog 4 ~ 5cN / dtex, lub elongation yog 5% ~ 7%, lub modulus yog 10 ~ 12GPa, lub zog tuav tus nqi yog 50% ~ 70% tom qab 100h ntawm 300 ℃, lub limiting oxygen index yog 44, thiab hluav taws xob tiv thaiv zoo.Ketone copolymerization fiber ntau muaj kwv yees li hollow zoo li seem, lub zog 3.8cN / dtex, elongation 32%, modulus 35cN / dtex, ceev 1.41g / cm, shrinkage ntawm boiling dej thiab 250 ℃ yog tsawg tshaj li 0.5% thiab 1%, feem.

Nws yog siv rau cov khoom siv lim dej kub, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, txhua yam kub thiab nplaim hluav taws tiv thaiv khaub ncaws, parachute, honeycomb qauv thiab cov khoom siv thaum tshav kub kub sealing, cov khoom siv sib xyaw thiab cov khoom siv tiv thaiv hluav taws xob.
