I-Acrylonitrile ye-NBR
I-Acrylonitrile ye-NBR,
Acrylonitrile for NBR Nitrile, Acrylonitrile for Acrylonitrile Butadiene Rubber, Acrylonitrile for irabha yeNitrile,
I-NBR (i-Nitrile), i-chemically, i-copolymer ye-butadiene kunye ne-acrylonitrile.Umxholo we-Acrylonitrile uyahluka kwiimveliso zorhwebo ukusuka kwi-18% ukuya kwi-50%.Njengoko umxholo we-NBR ukhula, ukuchasana ne-oyile yesiseko se-petroleum kunye ne-hydrocarbon fuels kwanda, kodwa ukuguquguquka kweqondo lokushisa eliphantsi kuncipha.
Malunga ne-NBR
Ngenxa yokumelana okugqwesileyo kwimveliso yepetroleum, kunye nokukwazi kwayo ukudityaniswa kwinkonzo kwiqondo lobushushu obuphakathi -35°C ukuya +120°C (-30°F ukuya +250°F), iNitrile/NBR yeyona nto ibanzi. kusetyenziswa i-elastomer kushishino lwetywina namhlanje.Kwakhona imilinganiselo emininzi yerabha yomkhosi yamafutha kunye ne-oyile exhathisa i-O-rings ifuna iikhompawundi ezisekelwe kwi-nitrile.
Kufuneka kukhankanywe ukuba ukufumana ukuxhathisa okulungileyo kubushushu obuphantsi, kuye kufuneke ukuba uncame ukuxhathisa ubushushu obuphezulu.Iikhompawundi ze-Nitrile ziphezulu kunee-elastomers ezininzi ngokubhekisele kwisethi yoxinzelelo, ukukrazuka, kunye nokuxhathisa kwe-abrasion.Iikhompawundi zeNitrile azikwazi ukumelana ne-ozone, ukukhanya kwelanga, okanye imozulu.Akufanele zigcinwe kufuphi neenjini zombane okanye ezinye izixhobo zokuvelisa i-ozone.

Ukupakishwa kunye nokuhanjiswa
Isicelo seMveliso
I-Acrylonitrile iveliswa ngokurhweba nge-propylene ammoxidation, apho i-propylene, i-ammonia, kunye nomoya ziphendulwa yi-catalyst kumbhede owenziwe ngamanzi.I-Acrylonitrile isetyenziswe ngokuyinhloko njenge-co-monomer kwimveliso ye-acrylic kunye ne-modacrylic fibers.Usetyenziso lubandakanya ukuveliswa kweeplastiki, iingubo ezingaphezulu, i-nitrile elastomers, i-barrier resins, kunye ne-adhesives.Ikwayikhemikhali ephakathi kwi-synthesis yee-antioxidants ezahlukeneyo, amayeza, idayi, kunye ne-surface-active.
1. I-Acrylonitrile eyenziwe nge-polyacrylonitrile fiber, ebizwa ngokuba yi-acrylic fiber.
2. I-Acrylonitrile kunye ne-butadiene inokwenziwa i-copolymerized ukuvelisa i-rubber ye-nitrile.
3. Acrylonitrile, butadiene, styrene copolymerized ukulungiselela ABS resin.
4. I-Acrylonitrile hydrolysis inokuvelisa i-acrylamide, i-acrylic acid kunye ne-esters yayo.
