Acrylonitrile mo NBR
Acrylonitrile mo NBR,
Acrylonitrile mo NBR Nitrile, Acrylonitrile mo Acrylonitrile Butadiene Rubber, Acrylonitrile mo Nitrile pa'u,
NBR (Nitrile), chemically, o se copolymer o le butadiene ma le acrylonitrile.Acrylonitrile anotusi eseese i oloa faapisinisi mai le 18% i le 50%.A'o fa'atupula'ia le anotusi o le NBR, e fa'atupula'ia le tete'e atu i suau'u fa'avae suau'u ma suau'u hydrocarbon, ae fa'aitiitia le fetu'una'i o le vevela.
E uiga ile NBR
Ona o lona teteʻe lelei i oloa suauʻu, ma lona gafatia e faʻapipiʻiina mo le tautua i luga o le vevela o le -35°C i le +120°C (-30°F i le +250°F), o le Nitrile/NBR e sili ona lautele. fa'aaogaina elastomer i le alamanuia fa'amaufa'ailoga i aso nei.O le tele fo'i o fa'amatalaga pa'u a le militeri mo le suau'u ma le suau'u O-mama e mana'omia ni fa'avae fa'avae nitrile.
E tatau ona taʻua e maua ai le teteʻe lelei i le maualalo o le vevela, e masani ona manaʻomia le ositaulagaina o le maualuga o le vevela.O fa'aputuga nitrile e sili atu nai lo le tele o elastomers e fa'atatau i le fa'apipi'i seti, loimata, ma le abrasion tete'e.O fa'aputuga nitrile e le lelei le tete'e atu i le osone, susulu o le la po'o le tau.E le tatau ona teuina i tafatafa o afi eletise poʻo isi mea e gaosia ai le osone.

Talosaga Oloa
Acrylonitrile e gaosia faapisinisi e le propylene ammoxidation, lea e tali atu ai le propylene, amonia, ma le ea e le catalyst i totonu o se moega vai.Acrylonitrile o loʻo faʻaaogaina muamua e avea o se faʻatasi-monomer i le gaosiga o alava acrylic ma modacrylic.Fa'aoga e aofia ai le gaosiga o palasitika, fa'apipi'i luga, elastomers nitrile, resini pa puipui, ma mea fa'apipi'i.Ose vaila'au va'ava'ai i le tu'ufa'atasiga o antioxidants eseese, vaila'au vaila'au, vali, ma luga-galue.
1. Acrylonitrile faia i le polyacrylonitrile fiber, e taʻua o le fiva acrylic.
2. Acrylonitrile ma butadiene e mafai ona copolymerized e maua ai le nitrile pa'u.
3. Acrylonitrile, butadiene, styrene copolymerized e saunia ABS resin.
4. Acrylonitrile hydrolysis e mafai ona maua ai le acrylamide, acrylic acid ma ona esters.
