Corrosion resistance yezvinhu zvakajairika zvevhavha - NBR

NBR inowanikwa ne emulsion polymerization yebutadiene uye acrylonitrile, uye NBR inonyanya kugadzirwa nekuderera kwekushisa emulsion polymerization. Yakanakisa mafuta kuramba, yakakwira kupfeka kuramba, yakanaka kupisa kupisa, kunamatira kwakasimba. Kukanganisa kwayo kushomeka kushomeka kwekushisa, kushomeka kwe ozone, kusashanda zvakanaka kwekudzivirira uye kuderera zvishoma. NBR inonyanya kushandiswa kugadzira mafuta anodzivirira rabha zvigadzirwa. NBR imhando yerabha yakagadzirwa kubva kubutadiene uye acrylonitrile. Iyo irabha yekugadzira ine yakanaka mafuta kuramba (kunyanya alkane mafuta) uye kuramba kuchembera. Acrylonitrile content (%) muNBR ndeye 42 ~ 46, 36 ~ 41, 31 ~ 35, 25 ~ 30 uye 18 ~ 24. Iyo yakakwirira yezvinyorwa zveacrylonitrile, zviri nani kupikisa kwemafuta, asi kuderera kwekudzivirira kutonhora. Mukuwedzera, ine mvura yakanaka yekudzivirira, kusimba kwemhepo uye kunamatira kwakanaka. Inoshandiswa zvakanyanya mukugadzira zvakasiyana-siyana zvinodzivirira mafuta erubha zvigadzirwa, zvakasiyana-siyana zvinodzivirira mafuta gaskets, gaskets, maoko, flexible packaging, flexible hose, kudhinda uye dhayi mabheti, cable rubber zvinhu, nezvimwewo. petroleum, kukopa uye mamwe maindasitiri.
