Acrylonitrile kuri NBR
Acrylonitrile ya NBR,
Acrylonitrile ya NBR Nitrile ， Acrylonitrile ya Acrylonitrile Butadiene Rubber ， Acrylonitrile ya Nitrile rubber,
NBR (Nitrile), muburyo bwa chimique, ni copolymer ya butadiene na acrylonitrile.Ibirimo Acrylonitrile biratandukanye mubicuruzwa kuva 18% kugeza 50%.Mugihe ibirimo NBR byiyongera, kurwanya amavuta yibanze ya peteroli hamwe na lisansi ya hydrocarubone biriyongera, ariko ubushyuhe buke buragabanuka.
Ibyerekeye NBR
Bitewe nuko irwanya cyane ibikomoka kuri peteroli, hamwe nubushobozi bwayo bwo kongerwaho serivisi hejuru yubushyuhe bwa -35 ° C kugeza kuri + 120 ° C (-30 ° F kugeza + 250 ° F), Nitrile / NBR ninshi cyane yakoresheje elastomer muruganda rwa kashe uyumunsi.Ibikoresho byinshi bya reberi ya lisansi yerekana amavuta na O-impeta bisaba amavuta ya nitrile.
Twabibutsa ko kugirango tubashe guhangana nubushyuhe buke, akenshi birakenewe kwigomwa ubushyuhe bwo hejuru.Ibikoresho bya Nitrile biruta elastomers nyinshi kubijyanye no guhunika, kurira, no kurwanya abrasion.Ibikoresho bya Nitrile ntabwo bifite imbaraga zo guhangana na ozone, izuba, cyangwa ikirere.Ntibigomba kubikwa hafi ya moteri yamashanyarazi cyangwa ibindi bikoresho bitanga ozone.

Acrylonitrile ikorwa mubucuruzi na propylene ammoxidation, aho propylene, ammonia, numwuka byitabirwa na catalizator muburiri bwuzuye amazi.Acrylonitrile ikoreshwa cyane cyane nka co-monomer mugukora fibre acrylic na modacrylic.Imikoreshereze ikubiyemo umusaruro wa plastiki, gutwikira hejuru, nitrile elastomers, inzitizi za barrière, hamwe na adhesives.Nubundi buryo bwa chimique hagati muguhuza antioxydants zitandukanye, imiti, amarangi, hamwe nubutaka bukora.
1. Acrylonitrile ikozwe muri fibre polyacrylonitrile, ni fibre acrylic.
2. Acrylonitrile na butadiene birashobora gukoporora kugirango bibyare nitrile.
3. Acrylonitrile, butadiene, styrene copolymerized kugirango itegure ABS resin.
4. Acrylonitrile hydrolysis irashobora kubyara acrylamide, acide acrylic na est est.
