Rabha yechisikigo, sezvatinowanzo taura nezvayo, chinhu chakasimba chakagadzirwa kubva kune yechisikigo latex inounganidzwa kubva mumiti yerabha, mushure mekubatana, kuomesa uye mamwe maitiro ekugadzirisa.Rabha yechisikigo musanganiswa wepolymer ine polyisoprene sechikamu chayo chikuru, ine molecular formula (C5H8) n.Rubber hydrocarbon yaro (polyisoprene) yemukati inodarika makumi mapfumbamwe kubva muzana, uye ine zvakare mashoma mapuroteni, mafuta acids, shuga nemadota.
Zvinhu zvenyama zverabha rechisikigo.Rabha yechisikigo ine yakakwira elasticity patembiricha yekamuri, purasitiki shoma, yakanaka kwazvo mechanical simba, yakaderera hysteresis kurasikirwa, yakaderera kupisa chizvarwa panguva yakawanda deformation, saka ayo flexural resistance zvakare yakanaka kwazvo, uye nekuti isiri-polar rabha, ine zvakanaka. magetsi ekudzivirira zvinhu.
Rubha, pamwe chete nemapurasitiki nemafibhi, chimwe chezvitatu zvekugadzira zvine huremu hwepamusoro hwekutatarika uye elasticity.Rubber inoratidzwa kekutanga nediki modulus ye elasticity uye yakakwira elongation rate.Chechipiri, ine yakaringana kumira zvakanaka kupermeability pamwe nekuramba kune akasiyana makemikari media uye magetsi ekudzivirira.Mamwe akakosha ekugadzira rubber ane yakanaka mafuta uye tembiricha kuramba, kuramba kuzvimba kwemafuta emafuta, mafuta ekuzora, hydraulic oiri, mafuta emafuta uye anonyungudutsa mafuta;kutonhora kwekudzivirira kunogona kudzika kusvika -60 ° C kusvika -80 ° C uye kupisa kwekudzivirira kunogona kusvika +180 ° C kusvika +350 ° C.Rubha zvakare inoshingirira kune ese marudzi ekuchinja uye kubhenda deformation, sezvo kurasikirwa kwehysteresis kuri kudiki.Chimiro chechitatu cherubha ndechekuti inogona kushandiswa, yakasanganiswa uye yakasanganiswa nezvinhu zvakasiyana-siyana uye nokudaro inogadziriswa kuitira kuti uwane kusanganiswa kwakanaka kwezvinhu.
