Kurwanya ruswa yibikoresho bisanzwe kuri valve - NBR

NBR ibonwa na emulion polymerisation ya butadiene na acrylonitrile, kandi NBR ikorwa ahanini nubushyuhe buke bwa emulion polymerisation. Kurwanya amavuta meza cyane, kwihanganira kwambara cyane, kurwanya ubushyuhe bwiza, gukomera cyane. Ingaruka zayo ni ubukonje buke buke, kurwanya ozone nabi, imikorere idahwitse hamwe na elastique nkeya. NBR ikoreshwa cyane mugukora amavuta ya reberi irwanya amavuta. NBR ni ubwoko bwa reberi yubukorikori ikozwe muri butadiene na acrylonitrile. Ni reberi ya sintetike ifite amavuta meza (cyane cyane amavuta ya alkane) hamwe no gusaza. Ibigize Acrylonitrile (%) muri NBR ni 42 ~ 46, 36 ~ 41, 31 ~ 35, 25 ~ 30 na 18 ~ 24. Iyo ibirimo acrylonitrile byinshi, niko amavuta arwanya amavuta, ariko bikagabanya ubukonje bukabije. Byongeye kandi, ifite amazi meza yo kurwanya, gukomera kwumwuka no gufatana neza. Ikoreshwa cyane mugukora ibicuruzwa bitandukanye birwanya amavuta ya reberi, gasketi zitandukanye zidashobora kwihanganira amavuta, gasketi, amaboko, gupakira byoroshye, imashini yoroheje, gucapa no gusiga amarangi, ibikoresho bya reberi, nibindi byahindutse ibikoresho bya elastique byingirakamaro mumodoka, indege, peteroli, gukopera nizindi nganda.
