Ukumelana nokubola kwezinto eziqhelekileyo kwiivalvu - NBR
2021-06-15
I-NBR ifunyenwe nge-emulsion polymerization ye-butadiene kunye ne-acrylonitrile, kwaye i-NBR iveliswa ikakhulu ngobushushu obuphantsi be-emulsion polymerization. Ukuchasana kwe-oyile okugqwesileyo, ukumelana nokunxiba okuphezulu, ukumelana nobushushu obuhle, ukuncamathela okuqinileyo. Ukungalungi kwayo kukunganyangeki kobushushu obuphantsi, ukunganyangeki kwe-ozone, ukusebenza kakubi kokugquma kunye nokunwebeka okuphantsi kancinci. I-NBR isetyenziswa ikakhulu ukwenza iimveliso zerabha ezixhathisa i-oyile. I-NBR luhlobo lwerabha eyenziwe nge-butadiene kunye ne-acrylonitrile. Yirabha yokwenziwa kunye nokumelana neoli elungileyo (ingakumbi ioli yealkane) kunye nokumelana nokuguga. Umxholo we-Acrylonitrile (%) kwi-NBR yi-42 ~ 46, 36 ~ 41, 31 ~ 35, 25 ~ 30 kunye ne-18 ~ 24. Ukuphakama komxholo we-acrylonitrile, kungcono ukuchasana kweoli, kodwa kuphantsi ukuchasana nokubanda. Ukongeza, inokumelana kakuhle namanzi, ukuqina komoya kunye nokuncamathela okugqwesileyo. Isetyenziswa ngokubanzi ukwenza iimveliso zerabha ezixhathisa ioyile, iigaskets ezixhathisa ioyile, iigaskets, imikhono, ukupakishwa okubhetyebhetye, ithumbu elibhetyebhetye, ukuprinta kunye nokudaya iibhedi, izixhobo zerabha yentambo, njl. i-petroleum, ukukopa kunye namanye amashishini.
