Polyacrylonitrile (PAN), tseem hu ua polyvinyl cyanide thiab Creslan 61, yog hluavtaws, semicrystalline organic polymer resin , nrog cov qauv linear (C 3 H3N) . … PAN fibers yog cov tshuaj ua ntej ntawm cov pa roj carbon fiber ntau zoo.
polyacrylonitrile yog dab tsi?
Polyacrylonitrile (PAN) yog synthetic polymer nrog tus qauv linear (C 3 H 3N) . Txawm hais tias nws yog thermoplastic nws tsis yaj nyob rau hauv ib txwm muaj mob, vim nws degrades ua ntej melting ntawm siab tshaj 300 ° C. Yuav luag tag nrho cov PAN resins yog copolymers ua los ntawm kev sib xyaw ntawm cov monomers, nrog acrylonitrile ua cov khoom tseem ceeb.
YPuas yog polyacrylonitrile ib qho tshuaj?
Feem ntau polyacrylonitrile yog tsim los ua acrylic thiab modacrylic fiber, ib qho kev hloov pauv rau ntaub plaub hauv khaub ncaws thiab khoom vaj khoom tsev. Acrylonitrile (CH2=CHCN), cov khoom sib xyaw tau los ntawm kev ua haujlwm propylene nrog ammonia (NH3)…
Puas yog polyacrylonitrile tshuaj lom?
Yuav ua rau qhov muag thiab tawv nqaij khaus. Tej zaum yuav ua rau ua pa thiab digestive ib ntsuj av. Metabolized rau cyanide hauv lub cev, uas yuav ua rau mob taub hau, kiv taub hau, qaug zog, tsis nco qab, convulsions, coma thiab ua tau tuag.
