Kukana kwa dzimbiri kwa zida wamba zamavavu - NBR

NBR ndi akamagwira emulsion polymerization wa butadiene ndi acrylonitrile, ndi NBR makamaka opangidwa ndi otsika kutentha emulsion polymerization. Kukana kwabwino kwamafuta, kukana kwambiri kuvala, kukana kutentha kwabwino, kumamatira mwamphamvu. Zoyipa zake ndi kusakanizidwa bwino kwa kutentha, kukana kwa ozoni, kusagwira bwino ntchito komanso kutsika pang'ono. NBR imagwiritsidwa ntchito kwambiri popanga zinthu za rabara zosagwira mafuta. NBR ndi mtundu wa rabara wopangidwa kuchokera ku butadiene ndi acrylonitrile. Ndi mphira wopangidwa ndi mafuta abwino (makamaka alkane mafuta) komanso kukana kukalamba. Acrylonitrile (%) mu NBR ndi 42 ~ 46, 36 ~ 41, 31 ~ 35, 25 ~ 30 ndi 18 ~ 24. Zomwe zili pamwamba pa acrylonitrile, zimakhala bwino kukana mafuta, koma kumachepetsa kuzizira. Kuphatikiza apo, ili ndi kukana kwamadzi bwino, kulimba kwa mpweya komanso kumamatira kwambiri. Amagwiritsidwa ntchito popanga zinthu zosiyanasiyana za mphira zolimbana ndi mafuta, ma gaskets osagwirizana ndi mafuta, ma gaskets, manja, ma CD osinthika, payipi yosinthika, machira osindikizira ndi utoto, zida za mphira, etc. mafuta, kukopera ndi mafakitale ena.
