Acrylonitrile kuri NBR
Acrylonitrile ya NBR,
Acrylonitrile Kuri Nitrile Rubber,
Nitrile (bakunze kwita buna-N reberi cyangwa perbunan) ni elastomer ikoreshwa cyane munganda zidodo.Nitrile ni copolymer ya monomers ebyiri: acrylonitrile (ACN) na butadiene.Imiterere yibi bikoresho bya reberi bigenwa nibirimo ACN, bigabanijwemo ibyiciro bitatu:
Nitrile ndende> 45% birimo ACN,
Hagati ya nitrile 30-45% ya ACN,
Nitrile nkeya <30% ibirimo ACN.
Iyo ACN iri hejuru, niko irwanya amavuta ya hydrocarubone.Hasi yibirimo ACN nibyiza guhinduka mubikorwa byubushyuhe buke.Hagati ya nitrile rero, irasobanuwe cyane bitewe nuburinganire bwiza muri rusange.Ubusanzwe, nitrile irashobora kongerwamo imbaraga kugirango ikore hejuru yubushyuhe bwa dogere 35 ° C kugeza kuri + 120 ° C kandi iruta elastomers nyinshi mubijyanye no guhonyora, kurira no kurwanya abrasion.

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.
