Imikhiqizo

I-Acrylonitrile ye-PAN

Incazelo emfushane:

I-acrylonitrile iwuketshezi olungenambala kuya kokuphuzi okuphaphathekile kanye noketshezi olushintshashintshayo oluncibilika emanzini kanye nezincibilikisi eziphilayo ezivame kakhulu njenge-acetone, benzene, carbon tetrachloride, ethyl acetate, ne-toluene.I-Acrylonitrile ikhiqizwa ukuthengisa nge-propylene ammoxidation, lapho i-propylene, i-ammonia, nomoya kusabela nge-catalyst embhedeni omanzi.I-Acrylonitrile isetshenziswa ngokuyinhloko njenge-co-monomer ekukhiqizeni imicu ye-acrylic ne-modacrylic.Izinto ezisetshenziswayo zihlanganisa ukukhiqizwa kwamapulasitiki, okokugcotshwa okungaphezulu, ama-nitrile elastomers, ama-barrier resins, nama-adhesives.Iphinde ibe yikhemikhali emaphakathi ekuhlanganisweni kwama-antioxidants ahlukahlukene, amakhemisi, odayi, kanye ne-surface-active.


Imininingwane Yomkhiqizo

Omaka bomkhiqizo

I-Acrylonitrile ye-PAN,
I-Acrylonitrile Ye-Polyacrylonitrile, I-Acrylonitrile ye-polyacrylonitrile fiber,

I-Polyacrylonitrile (PAN) iyi-polymer yokwenziwa enefomula yomugqa (C3H3N)n.Nakuba iyi-thermoplastic ayincibiliki ngaphansi kwezimo ezijwayelekile, njengoba iyehla ngaphambi kokuncibilika ngaphezu kuka-300 °C.Cishe wonke ama-PAN resins angama-copolymers enziwe ngezingxube zama-monomers, ne-acrylonitrile njengengxenye eyinhloko.Kuyi-polymer eguquguqukayo esetshenziselwa ukukhiqiza imikhiqizo eminingi ehlukahlukene, okuhlanganisa imicu yendwangu, ulwelwesi olucwenga kakhulu, imicu engenalutho ye-osmosis ehlehlayo, njll. Imicu ye-PAN iyisandulela ekukhiqizeni imicu yekhabhoni yekhwalithi ephezulu.

Isicelo somkhiqizo

I-Acrylonitrile ikhiqizwa ukuthengisa nge-propylene ammoxidation, lapho i-propylene, i-ammonia, nomoya kusabela nge-catalyst embhedeni omanzi.I-Acrylonitrile isetshenziswa ngokuyinhloko njenge-co-monomer ekukhiqizeni imicu ye-acrylic ne-modacrylic.Izinto ezisetshenziswayo zihlanganisa ukukhiqizwa kwamapulasitiki, okokugcotshwa okungaphezulu, ama-nitrile elastomers, ama-barrier resins, nama-adhesives.Iphinde ibe yikhemikhali emaphakathi ekuhlanganisweni kwama-antioxidants ahlukahlukene, amakhemisi, odayi, kanye ne-surface-active.

1. I-Acrylonitrile eyenziwe nge-polyacrylonitrile fiber, okuyi-acrylic fiber.
2. I-Acrylonitrile ne-butadiene ingenziwa i-copolymerized ukuze ikhiqize irabha ye-nitrile.
3. I-Acrylonitrile, butadiene, styrene copolymerized ukulungiselela i-ABS resin.
4. I-Acrylonitrile hydrolysis ingakhiqiza i-acrylamide, i-acrylic acid nama-esters ayo.
