Irabha yeFluorine luhlobo lwerabha yokwenziwa equlethe iiathom zefluorine. Inokumelana nobushushu okugqwesileyo, ukumelana ne-oxidation, ukuxhathisa kweoli kunye nokuxhathisa amayeza. Isetyenziswa ikakhulu kwinqwelomoya, kushishino lweekhemikhali, i-petroleum, iimoto kunye namanye amasebe oshishino njengemathiriyeli yokutywina, imathiriyeli exhathisayo ephakathi kunye nemathiriyeli yokugquma. Irabha yokwenziwa equlethe iiathom zefluorine kwisakhiwo sayo semolekyuli.
Ngokuqhelekileyo ibonakaliswe ngenani le-athomu ze-fluorine zeeyunithi ezine-fluorine kwi-copolymer. Ngokomzekelo, i-fluororubber 23 i-copolymer ye-vinylidene fluoride kunye ne-chlorotrifluoroethylene. I-Fluororubber iyamelana nobushushu obuphezulu, ioli kunye nokubola kweekhemikhali.
Izinto eziluncedo zefluororubber:
1. Ukumelana nobushushu obuphezulu obugqwesileyo: ubushushu benkonzo busuka kwi-60 ℃ ukuya kwi-250 ℃. Ukuchasana kweoli egqwesileyo: ukuchasana nobushushu obuphezulu be-oyile ye-fuel, i-oyile yokuthambisa isulfure, i-hydraulic oil, i-diester oil, i-silicate ester kunye nezinye ioyile zingcono kunezinye iirubha.
3. Ukumelana okugqwesileyo kwi-corrosive medium kunye ne-oxidant eyomeleleyo; Uzinzo lwayo kwimithombo yeendaba eyomeleleyo efana ne-nitric acid evuthayo, i-sulfuric acid egxininisiweyo, i-hydrochloric acid, i-hydrogen peroxide kunye ne-alkali egxininisiweyo ingcono kunezinye iirubha.
4. Iimpawu ezilungileyo zomatshini, ukugquma kombane kunye nokumelana nemitha.
5. Ukuchasana okulungileyo kwi-vacuum ephezulu.
Umda wosetyenziso lwe-fluororubber:
1. Xa irubha ye-fluorine ichaphazeleka ngumswakama kunye namanzi okanye xa izinga lokushisa likhuphuka, utshintsho luncinci. Nangona i-silicon dioxide eveliswa kukutsha kwe-short-circuit kusekho i-insulator, iqinisekisa ukuba izixhobo zombane ziyaqhubeka nokusebenza, ngoko zifanelekile ukwenza iingcingo, iintambo kunye neengcingo ezihamba phambili.
2. Iityhubhu yeFluoroplastic ingasetyenziselwa ukuhambisa kunye nokutywina ezahlukeneyo zeasidi eyomeleleyo kunye nealkali, umphunga, umoya oshushu, ioyile eshushu kunye nolunye ulwelo. Ingasetyenziselwa izixhobo zasekhaya, izibane kunye nezixhobo zonyango; 3. Uxinzelelo olusebenzayo lwe-tube ye-fluororubber (0.5-3.0 MPa) inokukhuselwa ngokudibeneyo kunye nesigqubuthelo sensimbi engenasici.
4. I-Fluoroplastic strip nayo isetyenziselwa ibhatyi yocingo kwindawo yokusebenza enzima.;
5. I-Fluororubber inobushushu obubalaseleyo kunye nokumelana nokugqwala, kwaye inegama lokumkani werabha. Inokucutshungulwa ibe ityhubhu yerabha, iteyiphu yokuncamathelisa, ifilimu, igasket, (isakhelo) itywina leoli, “O” ring, “V” ring, njl., Ezisetyenziswa ngokubanzi kwinqwelomoya, iimoto, i-petroleum, ishishini lemichiza, unxibelelwano, isixhobo kunye nezinye iinkalo.
Njengoko sonke siyazi, i-valve nganye kufuneka isebenzise izinto zokutywina ezahlukeneyo, ezifana ne-ethylene propylene rubber (EPDM), i-nitrile rubber (NBR), i-polytetrafluoroethylene (PTFE), i-fluororubber (i-Viton), i-rubber ye-silicone (SEP), ukushisa kunye nokugqoka i-rubber ye-EPDM, i-cemented carbide, i-alloy steel.
