Acrylonitrile mo NBR
Acrylonitrile mo NBR,
Acrylonitrile Mo Nitrile Rubber,
Nitrile (e masani ona taʻua o le buna-N rubber poʻo le perbunan) o le elastomer e masani ona faʻaaogaina i le alamanuia faʻamaufaʻailoga.O le Nitrile o se kopi o monomers e lua: acrylonitrile (ACN) ma le butadiene.O meatotino o nei paʻu paʻu e faʻamoemoeina e lona ACN anotusi, lea e vaevaeina i ni faʻavasegaga se tolu:
Nitrile maualuga> 45% ACN anotusi,
Medium nitrile 30-45% ACN anotusi,
Nitrile maualalo <30% ACN anotusi.
O le maualuga o le ACN anotusi, o le sili atu foi lea o lona tetee atu i suauu hydrocarbon.O le maualalo o le ACN anotusi o le sili atu lea o lona fetuutuunai i mea maualalo vevela.Medium nitrile, o le mea lea, e sili ona faʻamaonia ona o lona paleni atoa lelei i le tele o talosaga.E masani lava, o nitriles e mafai ona faʻapipiʻiina e galue i luga o le vevela o le -35°C i le +120°C ma e sili atu nai lo le tele o elastomers e tusa ai ma le faʻapipiʻi seti, loimata ma le abrasion teteʻe.

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.
