Ukumelana nokugqwala kwezinto ezivamile zama-valve - NBR

I-NBR itholakala nge-emulsion polymerization ye-butadiene ne-acrylonitrile, futhi i-NBR ikhiqizwa ikakhulukazi izinga lokushisa eliphansi le-emulsion polymerization. Ukumelana nowoyela okuhle kakhulu, ukumelana nokugqoka okuphezulu, ukumelana nokushisa okuhle, ukunamathela okuqinile. Ukungalungi kwayo ukumelana nezinga lokushisa eliphansi eliphansi, ukumelana ne-ozone okungekuhle, ukusebenza kahle kwe-insulation kanye nokunwebeka kancane. I-NBR isetshenziswa kakhulu ukwenza imikhiqizo yerabha engazweli uwoyela. I-NBR iwuhlobo lwerabha yokwenziwa eyenziwe nge-butadiene ne-acrylonitrile. Iyirabha yokwenziwa enokumelana kahle nowoyela (ikakhulukazi uwoyela we-alkane) nokumelana nokuguga. Okuqukethwe kwe-Acrylonitrile (%) ku-NBR kungu-42 ~ 46, 36 ~ 41, 31 ~ 35, 25 ~ 30 no-18 ~ 24. Ukuphakama kokuqukethwe kwe-acrylonitrile, kungcono ukumelana nowoyela, kodwa kunciphisa ukumelana namakhaza. Ngaphezu kwalokho, inokumelana okuhle kwamanzi, ukucinana komoya nokunamathela okuhle kakhulu. Isetshenziswa kabanzi ekwenzeni imikhiqizo ehlukahlukene yenjoloba engamelana nowoyela, ama-gaskets ahlukahlukene amelana nowoyela, ama-gaskets, imikhono, ukupakishwa okuguquguqukayo, ipayipi eliguquguqukayo, imibhede yokuphrinta nokudaya, izinto zenjoloba yekhebula, njll. i-petroleum, ukukopisha nezinye izimboni.
