Imikhiqizo
I-Acrylonitrile ye-NBR
I-Acrylonitrile ye-NBR,
I-Acrylonitrile Yerabha yeNitrile,
I-Nitrile (evame ukubizwa ngokuthi i-buna-N rubber noma i-perbunan) iyi-elastomer esetshenziswa kakhulu embonini yezimpawu.I-Nitrile iyi-copolymer yama-monomers amabili: i-acrylonitrile (ACN) ne-butadiene.Izakhiwo zalezi zinhlanganisela zenjoloba zinqunywa okuqukethwe kwayo kwe-ACN, ehlukaniswe yaba izigaba ezintathu:
I-nitrile ephezulu > 45% okuqukethwe kwe-ACN,
I-nitrile emaphakathi 30-45% okuqukethwe kwe-ACN,
I-nitrile ephansi <30% yokuqukethwe kwe-ACN.
Ukuphakama kokuqukethwe kwe-ACN, kuba ngcono ukumelana nowoyela we-hydrocarbon.Ukuncipha kokuqukethwe kwe-ACN kwenza kube ngcono ukuguquguquka kwayo ezinhlelweni zokushisa eziphansi.Ngakho-ke, i-nitrile emaphakathi icaciswa kabanzi ngenxa yebhalansi yayo yonke enhle ezinhlelweni eziningi.Ngokujwayelekile, ama-nitriles angahlanganiswa ukuze asebenze ebangeni lokushisa elisukela -35°C kuya ku-+120°C futhi aphakeme kunama-elastomer amaningi ngokuphathelene nokucindezelwa kwesethi, ukudabuka nokungabambeki.

Iphakheji Nokulethwa
Isicelo somkhiqizo
I-Acrylonitrile ikhiqizwa ukuthengisa nge-propylene ammoxidation, lapho i-propylene, i-ammonia, nomoya kusabela nge-catalyst embhedeni omanzi.I-Acrylonitrile isetshenziswa ngokuyinhloko njenge-co-monomer ekukhiqizeni imicu ye-acrylic ne-modacrylic.Izinto ezisetshenziswayo zihlanganisa ukukhiqizwa kwamapulasitiki, okokugcotshwa okungaphezulu, ama-nitrile elastomers, ama-barrier resins, nama-adhesives.Iphinde ibe yikhemikhali emaphakathi ekuhlanganisweni kwama-antioxidants ahlukahlukene, amakhemisi, odayi, kanye ne-surface-active.
1. I-Acrylonitrile eyenziwe nge-polyacrylonitrile fiber, okuyi-acrylic fiber.
2. I-Acrylonitrile ne-butadiene ingenziwa i-copolymerized ukuze ikhiqize irabha ye-nitrile.
3. I-Acrylonitrile, butadiene, styrene copolymerized ukulungiselela i-ABS resin.
4. I-Acrylonitrile hydrolysis ingakhiqiza i-acrylamide, i-acrylic acid nama-esters ayo.
