I-Acrylonitrile ye-PAN
I-Acrylonitrile yePAN,
Acrylonitrile Kuba Polyacrylonitrile, I-Acrylonitrile ye-polyacrylonitrile fiber,
I-Polyacrylonitrile (PAN) i-polymer yokwenziwa kunye ne-linear formula (C3H3N) n.Nangona iyi-thermoplastic ayinyibiliki phantsi kweemeko zesiqhelo, kuba iyehla ngaphambi kokuba inyibilike ngaphezu kwe-300 °C.Phantse zonke ii-PAN resins zi-copolymers ezenziwe kwimixube ye-monomers, kunye ne-acrylonitrile njengeyona nto iphambili.I-polymer eguquguqukayo esetyenziselwa ukuvelisa iindidi ezinkulu zeemveliso, kubandakanywa iifayili zeempahla, iimbumba ze-ultra-filtration, iifayili ezingenanto ze-osmosis eguquguqukayo, njl njl.

Isicelo seMveliso
I-Acrylonitrile iveliswa ngokurhweba nge-propylene ammoxidation, apho i-propylene, i-ammonia, kunye nomoya ziphendulwa yi-catalyst kumbhede owenziwe ngamanzi.I-Acrylonitrile isetyenziswe ngokuyinhloko njenge-co-monomer kwimveliso ye-acrylic kunye ne-modacrylic fibers.Usetyenziso lubandakanya ukuveliswa kweeplastiki, iingubo ezingaphezulu, i-nitrile elastomers, i-barrier resins, kunye ne-adhesives.Ikwayikhemikhali ephakathi kwi-synthesis yee-antioxidants ezahlukeneyo, amayeza, idayi, kunye ne-surface-active.
1. I-Acrylonitrile eyenziwe nge-polyacrylonitrile fiber, ebizwa ngokuba yi-acrylic fiber.
2. I-Acrylonitrile kunye ne-butadiene inokwenziwa i-copolymerized ukuvelisa i-rubber ye-nitrile.
3. Acrylonitrile, butadiene, styrene copolymerized ukulungiselela ABS resin.
4. I-Acrylonitrile hydrolysis inokuvelisa i-acrylamide, i-acrylic acid kunye ne-esters yayo.
