Kugwiritsa ntchito
Chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri ndi acrylonitrile ndikupanga polyacrylonitrile, polima yosunthika yokhala ndi kukhazikika kwamafuta komanso kukana kwamankhwala. Polima iyi imagwiritsidwa ntchito kwambiri pamakampani opanga nsalu kuti apange zovala zapamwamba komanso nsalu zomwe zimatha kupirira zovuta zachilengedwe. Kuonjezera apo, acrylonitrile ndi yofunika kwambiri popanga mphira wa nitrile, womwe umadziwika chifukwa cha mafuta abwino komanso kukana mankhwala. Izi zimapangitsa kukhala chisankho chodziwika bwino popanga magolovesi, zisindikizo ndi ma gaskets omwe amagwiritsidwa ntchito m'mafakitale amagalimoto, azaumoyo ndi mafuta.
Acrylonitrile imathandizanso kwambiri pakupanga utoto ndi utomoni wopangira. Kapangidwe kake ka mankhwala kumatha kugwiritsidwa ntchito popanga utoto wowoneka bwino komanso wokhalitsa wogwiritsa ntchito kuyambira nsalu mpaka inki zosindikizira. Kuphatikiza apo, kugwiritsidwa ntchito kwake muutomoni wopangira kumathandizira kupanga zida zolimba komanso zopepuka zomanga, mipando ndi mafakitale amagalimoto. Makhalidwewa amachititsa kuti acrylonitrile ikhale yofunika kwambiri popanga zinthu zomwe zimafuna mphamvu komanso kukongola.
Kuphatikiza pa ntchito zake pakupanga, acrylonitrile imagwiritsidwanso ntchito m'makampani opanga mankhwala. Ndiwo maziko a mankhwala osiyanasiyana, kuphatikizapo maantibayotiki, antihistamines ndi mankhwala a khansa. Kuthekera kwake kuchitapo kanthu ndi mankhwala ena kumapangitsa kuti pakhale kaphatikizidwe ka mamolekyu ovuta omwe ali ndi mankhwala achire. Izi zikuwonetseratu kufunika kwa acrylonitrile m'chipatala, kuthandizira kupanga mankhwala opulumutsa moyo.
Pomaliza, acrylonitrile ndi chinthu chamtengo wapatali chomwe chasintha mafakitale osiyanasiyana. Ngakhale kuti amatha kuyaka komanso zoopsa zomwe zingakhalepo, kugwiritsidwa ntchito kwake popanga polyacrylonitrile, rabala ya nitrile, utoto, utomoni wopangira, ndi mankhwala kumapangitsa kuti ikhale gawo lofunika kwambiri pakupanga zamakono. Kaya akupanga nsalu zogwira ntchito kwambiri, zopangira zolimba kapena mankhwala opulumutsa moyo, acrylonitrile imathandizira kwambiri kupanga dziko lomwe tikukhalamo lero.
