Acrylonitrile kwa NBR
Acrylonitrile kwa NBR,
Acrylonitrile Kwa Nitrile Rubber,
Nitrile (yomwe nthawi zambiri imatchedwa buna-N rabara kapena perbunan) ndi elastomer yomwe imagwiritsidwa ntchito kwambiri pamakampani osindikizira.Nitrile ndi copolymer wa monomers awiri: acrylonitrile (ACN) ndi butadiene.Zomwe zimapangidwira mphirazi zimatsimikiziridwa ndi zomwe zili mu ACN, zomwe zimagawidwa m'magulu atatu:
Nitrile wambiri> 45% ACN zili,
Nitrile yapakatikati 30-45% ya ACN,
Low nitrile <30% ACN zili.
Kukwera kwa ACN kumapangitsa kuti mafuta a hydrocarbon azitha kukana bwino.Kutsika kwa zinthu za ACN kumapangitsa kusinthasintha kwake muzogwiritsa ntchito kutentha kochepa.Nitrile wapakatikati, motero, amatchulidwa kwambiri chifukwa cha kuchuluka kwake bwino pamagwiritsidwe ambiri.Nthawi zambiri, ma nitriles amatha kuphatikizidwa kuti azigwira ntchito pa kutentha kwa -35 ° C mpaka +120 ° C ndipo amakhala apamwamba kuposa ma elastomer ambiri pokhudzana ndi kupanikizika, kung'ambika ndi kukwapula.

Product Application
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.
