Kunze kwezvishoma zvigadzirwa zverabha, zvakawanda zvekugadzira rabha zvigadzirwa, senge rabha rechisikigo, zvinobvira moto kana kutsva. Parizvino, nzira huru dzinoshandiswa kuvandudza kudzoreredza kwemurazvo ndeyekuwedzera zvinodzoreredza murazvo kana mafiritsi anodzoreredza murazvo, uye kusanganisa nekugadzirisa nezvinhu zvinodzoreredza moto. Kune akatiwandei emhando dzemoto retardant tekinoroji yerabha:
1. Hydrocarbon rabha
Rabha reHydrocarbon rinosanganisira NR, SBR, BR, nezvimwewo. Hydrocarbon rabha kazhinji haina kushomeka kwekupisa uye kunonoka kwemurazvo, uye zvizhinji zvezvigadzirwa zvinoora panguva yekupisa magasi anobvira. Kuwedzera zvinodzosa moto inzira yakakosha yekuvandudza kudzoreredza kwemurazvo wehydrocarbon rabha, uye synergistic mhedzisiro yemurazvo retardants inoshandiswa kuwedzera kuvandudza murazvo wekudzoreredza. Nekudaro, kutarisisa kunofanirwa kubhadharwa kune yakashata mhedzisiro yehuwandu hwemurazvo retardant pane mechanical properties yerubha.
Wedzera murazvo unodzoreredza inorganic mafirita akadai se calcium carbonate, ivhu, talcum poda, chena kabhoni dema, Aluminium hydroxide, nezvimwe kuti uderedze chikamu chezvinobvira organic zvinhu. Calcium carbonate uye nitrogen alumina zvine endothermic mhedzisiro kana yaora. Iyi nzira inoderedza zvimwe zvemuviri uye zvemagetsi zvimiro zverubha zvinhu, uye huwandu hwekuzadza hahufanire kunge hwakanyanya.
Uye zvakare, kuwedzera iyo crosslinking density yerabha inogona kuwedzera iyo oksijeni index. Naizvozvo, inogona kuvandudza kunonoka kwemurazvo werabha. Izvi zvinogona kunge zvakakonzerwa nekuwedzera kwekushisa kwekuparara kwekushisa kwezvinhu zverubha. Iyi nzira yakashandiswa muEthylene propylene rubber
2. Halogenated rubber
Halogenated rubber ine halogen elements, ine okisijeni index kazhinji pakati pe28 ne45, uye oksijeni index yeFPM inotopfuura 65. Iyo yakakwirira yehalogen content muhalogenated rubber, inowedzera iyo oksijeni index. Rudzi urwu rwerabha pacharwo rune kunonoka kwemurazvo wemoto uye kuzvidzima pachazvo pakubatidza. Naizvozvo, kurapwa kwayo kwemoto kudzoreredza kuri nyore pane hydrocarbon rabha. Kuti uwedzere kunatsiridza kudzoreredza kwemurazvo wehalogenated rubber, nzira yekuwedzera mareta emoto inowanzogamuchirwa.
3. Heterochain rubber
Rudzi rwerabha rinomiririra zvakanyanya muchikamu ichi ndiro dimethyl silicone rubber, ine oxygen index inosvika 25. Nzira chaidzo dzinodzoreredza murazvo dzinoshandiswa ndedzekuwedzera tembiricha yekuora kwayo, kuwedzera zvakasara panguva yekuora kwekupisa, uye kuderedza chiyero chekugadzira. magasi anobvira.
