Acrylonitrile bakeng sa NBR
Acrylonitrile bakeng sa NBR,
Acrylonitrile bakeng sa NBR Nitrile, Acrylonitrile bakeng sa Acrylonitrile Butadiene Rubber, Acrylonitrile bakeng sa rabara ea Nitrile,
NBR (Nitrile), ka lik'hemik'hale, ke copolymer ea butadiene le acrylonitrile.Litaba tsa Acrylonitrile li fapana ka lihlahisoa tsa khoebo ho tloha ho 18% ho ea ho 50%.Ha litaba tsa NBR li ntse li eketseha, ho hanyetsa oli ea motheo ea petroleum le mafura a hydrocarbon ho eketseha, empa ho fetoha ha mocheso o tlase ho fokotseha.
Mabapi le NBR
Ka lebaka la ho hanyetsa ha eona lihlahisoa tsa petroleum, le bokhoni ba eona ba ho kopanngoa bakeng sa tšebeletso ho feta mocheso oa -35 ° C ho ea + 120 ° C (-30 ° F ho +250 ° F), Nitrile / NBR ke eona e pharaletseng ka ho fetisisa. e sebelisa elastomer indastering ea tiiso kajeno.Hape litlhaloso tse ngata tsa rabara ea sesole bakeng sa mafura le li-O-ring tse hanyetsanang le oli li hloka metsoako e thehiloeng ho nitrile.
E lokela ho boleloa hore ho fumana khanyetso e ntle ho mocheso o tlase, hangata hoa hlokahala ho tela ho hanyetsa mocheso o phahameng.Lik'hemik'hale tsa Nitrile li phahametse li-elastomer tse ngata mabapi le compression set, ho taboha, le ho hanyetsa abrasion.Metsoako ea nitrile ha e na khanyetso e ntle ho ozone, khanya ea letsatsi kapa boemo ba leholimo.Ha lia lokela ho bolokoa haufi le li-motor tsa motlakase kapa lisebelisoa tse ling tse hlahisang ozone.

Acrylonitrile e hlahisoa khoebong ka propylene ammoxidation, eo ho eona propylene, ammonia, le moea li tšoaroang ke catalyst betheng e nang le metsi.Acrylonitrile e sebelisoa haholo-holo e le co-monomer ha ho etsoa li-acrylic le modacrylic fibers.Litšebeliso li kenyelletsa tlhahiso ea li-plastiki, li-coatings, li-elastomer tsa nitrile, li-resin tse thibelang, le li-adhesives.Hape ke lik'hemik'hale tse lipakeng tsa motsoako oa li-antioxidants tse fapaneng, meriana, lidae le tse sebetsang ka holim'a metsi.
1. Acrylonitrile e entsoeng ka fiber polyacrylonitrile, e leng fiber ea acrylic.
2. Acrylonitrile le butadiene li ka etsoa copolymerized ho hlahisa rabara ea nitrile.
3. Acrylonitrile, butadiene, styrene copolymerized ho lokisetsa ABS resin.
4. Acrylonitrile hydrolysis e ka hlahisa acrylamide, acrylic acid le esters ea eona.
