Acrylonitrile kwa NBR,
Acrylonitrile ya NBR Nitrile, Acrylonitrile ya Acrylonitrile Butadiene Rubber, Acrylonitrile ya rabala ya Nitrile,
NBR (Nitrile), mankhwala, ndi copolymer wa butadiene ndi acrylonitrile.Zomwe zili mu Acrylonitrile zimasiyana muzinthu zamalonda kuchokera ku 18% mpaka 50%.Pamene zinthu za NBR zikuchulukirachulukira, kukana mafuta amafuta amafuta ndi mafuta a hydrocarbon kumawonjezeka, koma kusinthasintha kwa kutentha kumachepa.
Za NBR
Chifukwa cha kukana kwambiri kwa mafuta a petroleum, komanso kutha kwake kuwonjezeredwa kuti agwiritsidwe ntchito pa kutentha kwa -35 ° C mpaka +120 ° C (-30 ° F mpaka +250 ° F), Nitrile / NBR ndiyomwe imapezeka kwambiri. amagwiritsa ntchito elastomer m'makampani osindikizira masiku ano.Komanso zambiri zamagulu a rabara ankhondo amafuta ndi ma O-rings osamva mafuta amafunikira mankhwala opangidwa ndi nitrile.
Ziyenera kunenedwa kuti kuti mupeze kukana kwabwino kwa kutentha kochepa, nthawi zambiri kumafunika kupereka nsembe kukana kutentha kwambiri.Mafuta a Nitrile ndi apamwamba kuposa ma elastomers ambiri okhudzana ndi compression set, kung'ambika, ndi kukana abrasion.Mankhwala a nitrile alibe kukana kwa ozoni, kuwala kwa dzuwa, kapena nyengo.Siziyenera kusungidwa pafupi ndi ma motors amagetsi kapena zida zina zopangira ozoni.

Acrylonitrile imapangidwa ndi malonda ndi propylene ammoxidation, momwe propylene, ammonia, ndi mpweya zimakhudzidwa ndi chothandizira pabedi lamadzimadzi.Acrylonitrile imagwiritsidwa ntchito makamaka ngati co-monomer popanga acrylic ndi modacrylic fibers.Ntchito zikuphatikizapo kupanga mapulasitiki, zokutira pamwamba, nitrile elastomers, zotchinga resins, ndi zomatira.Ndi mankhwala apakatikati pakupanga mitundu yosiyanasiyana ya antioxidants, mankhwala, utoto, komanso yogwira ntchito pamwamba.
1. Acrylonitrile yopangidwa ndi polyacrylonitrile fiber, yomwe ndi acrylic fiber.
2. Acrylonitrile ndi butadiene akhoza kupangidwa ndi copolymerized kuti apange mphira wa nitrile.
3. Acrylonitrile, butadiene, styrene copolymerized kukonzekera ABS utomoni.
4. Acrylonitrile hydrolysis imatha kupanga acrylamide, acrylic acid ndi esters ake.
