Material properties
Nitrile rabha irabha rekugadzira rakagadzirwa ne emulsion polymerization yebutadiene uye acrylonitrile. Kuita kwayo kunonyanya kutsanangurwa neiyo acrylonitrile yemukati (kazhinji iri pakati pe18% ne50%).
● Polarity maitiro:Boka recyano (-CN) muacrylonitrile molecules rine polarity yakasimba, izvo zvinoita kuti nitrile rabha rirambe richishingirira kune asiri-polar kana asina kusimba epolar oiri nezvinonyungudutsa (kunyanya kusiyana kwepolar, ndiko kuwedzera kuenderana).
● Kuchinja uye elasticity:Iyo butadiene kuumbwa kunoipa iyo yakanakisa kuchinjika uye inomanikidza kusimba, ichiigonesa kuchinjika kune kushoma kusaenzana kana vibration panzvimbo yekuisa chisimbiso.
● Yakanakisa processability:Zviri nyore kuita vulcanize nekuumba, uye zvinogona kugadzirwa kuita zvakasiyana-siyana zvemagaskets (senge maflat gaskets, O-rings, uye akakosha-gaskets akaumbwa), uye mutengo wakaderera pane weakawanda akakosha erabha.
Kuitwa kwenitrile rubber (kunyanya kupisa kwayo uye kushorwa kwemafuta) kunonyanya kugadziriswa ne acrylonitrile (ACN) content. Kukwirira kwezviri mukati, ndiko kusimba kwekusagadzikana kweoiri uye kusapisa kupisa, asi zvakanyanya kuderera-kudzikama kwetembiricha. Sarudzo inofanira kunge yakavakirwa pane tembiricha

Kufurira kwepakati pakushivirira kwekushisa
Kupisa kwekushisa kwe nitrile rubber kunosiyana zvichienderana nepakati iyo inosangana nayo, uye sarudzo inofanira kugadziriswa maererano nemhando yepakati.
Kusangana nemafuta (mineral oil, hydraulic oil, etc.):Mafuta anogona kunonoka oxidation uye kuchembera kwe nitrile rabha. Iyo chaiyo yekumusoro muganho wekupikiswa kwekushisa inogona kukwira zvishoma pane kuita kwayo mumhepo (somuenzaniso, nitrile rabha ine yepakati acrylonitrile content inogona kumira 120 dhigirii kwenguva yakareba mumafuta, asi inokurudzirwa kuti isapfuure 100℃mumhepo).
Kubata nemhepo kana mvura:Iko kunotarisirwa kupisa kwekushisa kunofanira kuderedzwa. The oxidation rate inowedzera pakupisa kwakanyanya. Kana yakashandiswa mumhepo kwenguva yakareba, iyo yepamusoro tembiricha muganho we nitrile rabha ine yepakati acrylonitrile yemukati inokurudzirwa kudzikiswa kusvika ku100 degree.
Dzivisa kusangana ne polar solvents (doro, ketones, nezvimwewo):Midhiya yakadaro inogona kuita kuti nitrile rubber iwedzere, uye kuzvimba kunowedzera pakupisa kwakanyanya. Kunyangwe pakudziya kwakadzika, inogona kutadza, uye zvinhu zvinofanirwa kutsiviwa kutanga (sekushandisa fluororubber).
