Encapsulated O-ring ke motsoako oa elasticity ea rabara le ho tiisa le ho hanyetsa lik'hemik'hale tsa Teflon, e entsoe ka rabara ea silicone kapa fluoroelastomer ka hare le Teflon FEP kapa Teflon PFA e batlang e le tšesaane ka ntle, rabara ena hammoho le Teflon o-ring e tla ba le ts'ebetso e babatsehang ea ho tiisa.
Kakaretso ea li-o-rings (O-rings) e bonolo ho apara, ho hanyetsa lik'hemik'hale tse fokolang le ho hanyetsa khase ea khase (ntle le FFKM), ha li-rings tsa Teflon O-rings li thata ebile li hanyetsa ho hatelloa empa ha li khone ho fetoha habonolo.Teflon FEP / Teflon PFA ORING e na le khanyetso e ntle ea ho phahama ha solvent le botsitso ba lik'hemik'hale (ntle le mocheso o phahameng ka tšepe, fluorine le halide e 'ngoe),' me e na le elasticity e ntle haufi le karolo ea rabara ea o-ring (O-ring).Thepa ena e etsa hore Encapsulated o-ring e loketse ho sebelisoa libakeng tse thata.
Motsoako oa sekoahelo sa Teflon FEP / Teflon PFA e teteaneng, e ts'oanang le e se nang kopanelo le mokokotlo oa rabara o fana ka tiiso e tsitsitseng ho pholletsa le Encapsulated o-ring.Sekhahla sa elastic le compressive sebakeng se seng le se seng sa o-ring se tšoana 'me se ka kenngoa hape tlas'a khatello e sa khaotseng.Ha khatello ea mecha ea litaba e ntse e eketseha, o-ring e hatelloa 'me Encapsulated o-ring e sebetsa joaloka mokelikeli oa viscous haholo, o fetisetsa khatello e sebetsang ho eona ka litsela tsohle ntle le ho fokotseha.
Ho ba teng ha sekoahelo sa Teflon FEP ho etsa hore Encapsulated o-ring e hanyetsane le ho thatafala le brittleness, athe silicone kapa fluoroelastomer core e lumella tiiso ho boloka elasticity e ntle mocheso ho fihlela ho 200 ° C.
Liphetho tsa liteko tsa rabara ea FFKM, rabara ea FKM le FEP/PFA e koahetsoeng ka o-ring ka sesebelisoa sa compression e bonts'a hore thepa ea 'mele ea rabara ea silicone kapa fluoroelastomer e kopantsoeng le thepa ea lik'hemik'hale ea Teflon FEP/Teflon PFA e fella ka o-ring e koahetsoeng ka botle. ho hanyetsa khatello ha u ntse u boloka thepa ea rabara.
The Encapsulated o-ring e etsoa tlas'a taolo e thata ea boleng ka ho sebelisa mokhoa o khethehileng o lumellang Teflon FEP polymer ho koahela ka ho feletseng mokokotlo oa rabara le ho etsa bonnete ba hore o-ring e na le mamello e hlokahalang e tloaelehileng.Lintlha tse sebelisitsoeng li bontša boitlamo ba rona ho boleng ba lihlahisoa tsa rona tsa Encapsulated o-ring, tse thehiloeng tlhahlobong ea ts'ebetso le taolo e tiileng ea boleng ho netefatsa khotsofalo ea bareki le tšebeliso e sireletsehileng.Li-o-rings tse kentsoeng ka tsela e 'ngoe kapa tse ling ha li bapisoe ka ho tiisa le ho phela nako e telele ha li bapisoa le rabara leha e le efe kapa Teflon o-ring e hloekileng, haholo-holo lits'ebetsong tse thata tsa mecha ea litaba.
