Aramid Synthetic Fiber ntau

Molecular{0}}Level Permanent Properties of Aramid Synthetic Fiber

Ntawm cov qib siab tshaj plaws organic hluavtaws fibers tam sim no tsim los ntawm kev lag luam yog aramid fibers. Lawv yog cov tshuaj tsw qab polyamide tsev neeg ntawm siab -cov khoom siv hluavtaws polymers. Cov fibers 'ntev ntev - ntev ntev - kev ua tau zoo yog los ntawm cov khoom siv lub nplhaib uas muaj ntxhiab tsw zoo raws li lawv cov pob txha molecular, tsis yog los ntawm cov txheej txheej saum npoo ib ntus uas tuaj yeem tawg tau dhau lub sijhawm. Cov khoom siv lub nplhaib uas muaj ntxhiab tsw zoo nyob ntawm lawv cov pob txha molecular yog dab tsi muab cov fibers lawv ntev -tuaj yeem ua kom muaj zog ntau dua - sij hawm. Peb cov kev xaiv dav dav ntawm aramid fibers suav nrog ob lub ntsiab polymer configurations: para-aramid (PPTA, Aramid 1414), tsim los rau ultrahigh tensile zog thiab modulus, thiab meta-aramid (PMIA, Aramid 1313), optimized rau thermal thiab hluav taws xob rwb thaiv tsev self-nplaum. Ntxiv nrog rau kev tsim{{14} thiab kev ua kom zoo dua {14} nplaim taws-cov khoom tsis zoo uas tiv thaiv melting los yog poob thaum ignited, ob qho tib si variations ua tsis tu ncua nyob rau hauv ib tug dav kub ntau yam, los ntawm -196℃mus rau ib tug tas li 204 degree. Tsis tas li ntawd, lawv cov qauv molecular muab muaj zog tiv thaiv rau feem ntau ntawm inorganic acids, alkalis nyob rau hauv chav tsev kub, thiab txuas ntxiv UV hluav taws xob, lav lub xyoo caum ntawm kev siv nyob rau hauv nyuaj industrial chaw.

Tag Nrho -Nqe Kev Lag Luam Layout ntawm Aramid Synthetic Fiber

Peb cov saw hlau sib xyaw ua ke tshem tawm qhov kev pheej hmoo ntawm kev hloov pauv zoo cuam tshuam nrog thib peb - cov ntaub ntawv raw los ntawm kev npog txhua kauj ruam ntawm cov txheej txheem tsim cov aramid fiber ntau, los ntawm raw monomer polymerization mus rau spinning, crimping, txiav, thiab kho qhov chaw. Cov khoom siv tiv thaiv tus kheej, cov khoom siv roj hmab hauv tsheb, kev sib txuas lus kho qhov muag, kev pom ib puag ncig, thiab cov khoom siv hauv aerospace yog tsib lub ntsiab kev lag luam hauv qab tau txais los ntawm peb cov khoom lag luam uas nws kim heev, uas suav nrog cov filament txuas ntxiv, staple fiber, tws fiber, pulp, thiab ntawv - qib variations. Tsis tas li ntawd, peb tsim customised, haumxeeb aramid fibers uas mus dhau qhov yooj yim thermal thiab mechanical kev ua tau zoo, xws li mus tas li conductive versions rau tawg- pov thawj tiv thaiv iav.
