Polyimide Fiber

Fiber polyimide, oo sidoo kale loo yaqaan fiber arylimide, waxaa loola jeedaa silsiladda molecular ee ka kooban fiber arylimide.

Awoodda fiber ether homopexed waa 4 ~ 5cN / dtex, elongation waa 5% ~ 7%, modules waa 10 ~ 12GPa, heerka haynta xoogga waa 50% ~ 70% ka dib 100h at 300 ℃, index oxygen xaddiday waa 44, iyo iska caabbinta shucaaca ayaa wanaagsan. Ketone copolymerization fiber waxay leedahay qiyaastii qayb qaabaysan, xoog 3.8cN/dtex, elongation 32%, modules 35cN/dtex, cufnaanta 1.41g/cm, yaraynta biyaha karkaraya iyo 250℃ waxay ka yar tahay 0.5% iyo 1%, siday u kala horreeyaan.

Waxaa loo istcimaalaa walxaha shaandhaynta siigada heer-kulka sare, walxaha dahaarka korantada, dhammaan noocyada kala duwan ee heerkulka sare iyo dharka ilaalinta ololka, baarashuudka, qaab-dhismeedka malabka iyo walxaha kulaylka, xoojinta walxaha isku dhafan iyo walxaha ka-hortagga shucaaca.
