IFayibha yePolyimide

I-Polyimide fiber, eyaziwa ngokuba yi-arylimide fiber, ibhekisa kwikhonkco lemolekyuli equlethe ifayibha ye-arylimide.

Amandla e-ether homopexed fiber yi-4 ~ 5cN/dtex, i-elongation yi-5% ~ 7%, i-modulus yi-10 ~ 12GPa, izinga lokugcinwa kwamandla yi-50% ~ 70% emva kwe-100h kwi-300 ℃, i-oxygen indexing index. 44, kunye nokumelana nemitha kulungile.Ifiber yeKetone copolymerization inecandelo elimalunga nomngxuma, amandla 3.8cN/dtex, elongation 32%, modulus 35cN/dtex, ingxinano 1.41g/cm, ukushwabana kwamanzi abilayo kunye ne-250℃ ngaphantsi kwe-0.5% kunye ne-1%, ngokulandelanayo.

Isetyenziselwa ubushushu obuphezulu bezinto zokucoca uthuli, izinto zokugquma umbane, zonke iintlobo zobushushu obuphezulu kunye nempahla ekhusela ilangatye, iparashute, ubume becomb yobusi kunye nezinto zokutywina ubushushu, ukuqinisa izinto ezidibeneyo kunye nezinto ezichasene nemitha.
