Rubber Knowledge III: Rubber yeStyrene-Butadiene (SBR)
Rubha reStyrene-Butadiene (SBR muchidimbu) irabha rekugadzira rabha rakaumbwa ne copolymerization ye styrene ne butadiene. Ndiyo imwe yerabha dzekugadzira rabha dzinoshandiswa zvakanyanya pasi rose, ichipa inodarika 50% yerabha rese rekugadzira rabha. Hunhu hwayo huri pakati pehwerabha rechisikigo (NR) nerabha rebutadiene (BR), uye inozivikanwa nekudzivirira kwayo kupfeka zvakanaka, mutengo wakaderera, uye kugadzikana kwakanyanya.
| Nchimiro | Fkudya | Kuenzanisa nerabha yechisikigo (NR) |
| Kuramba kweAbrasion | Zviri nani pane NR, zvakakodzera pakushandisa ma "high friction" (sekunge matai anotsika) | Kusapfeka kweNR kwakaderera. |
| Akuramba | Kusadzivirira ma antioxidants ne ozone kuri nani pane NR (nekuda kwekuvapo kwe benzine rings) | NR inokurumidza kukwegura uye inoda kuwedzerwa mishonga inodzivirira kukwegura. |
| Kunyunguduka uye Kupisa | Kusimba kwesimba kwakaderera zvishoma pane kweNR, uye simba rekugadzira kupisa rakakwira zvakanyanya (fomura yacho inofanira kugadziriswa) | NR ine kusimba kwakanaka uye inokwanisa kugadzira kupisa kushoma. |
| Lkuramba kupisa kwakanyanya
| Kupisa kwakaderera kunoita kuti iome (kana mamiriro acho akanyanya kuipa, huwandu hwestyrene hwakawedzera). | Kupisa kwakaderera kunoita kuti iome zvakanyanya. (Styrene NR inodzivirira kutonhora zviri nani (-50°C inoramba ichichinjika)) |
| Kunamira kwerabha | Kuzvinamira kwakashata; kunoda kushandiswa kwe resin inonamira inosimudzira. | NR ine hunhu hwakanaka hwekuzvinamira. |
| Mutengo | pasi | Yakakwirira (inokanganiswa nemamiriro ekunze) |
Rabha yeStyrene-butadiene ine chinzvimbo chakakosha muindasitiri yematayi, ichipa matai simba rekudzivirira kupfekwa, simba rekudzivirira kukwegura uye kubata zvakanaka. Pamusoro pezvo, inoshandiswa zvakanyanya mu: zvikamu zvemotokari (zvisimbiso, zvinobata shock absorbers, nezvimwewo), zvigadzirwa zvemaindasitiri (mabhandi ekutakura, Kuvhara Rings, nezvimwewo), zvinhu zvekuvaka (machira asingapindi mvura), michina yekurapa (machubhu erabha ekurapa, magirovhosi, nezvimwewo), manamatidziro nependi, nezvimwewo.
Vagadziri vakuru vepasi rose: Sinopec, PetroChina, Lanxess, Trinseo, Asahi Kasei, nezvimwewo.
Mhando dzezvigadzirwa dzinosanganisira maO-rings nezvinhu zvakagadzirwa nevatengi.
