PTFE ama polymer O-Rings waxay leeyihiin iska caabin aad u wanaagsan ku dhawaad dhammaan kiimikooyinka ay ku jiraan asiidhka, saldhigyada, saliidaha, uumiga……
PTFE O-Rings Hordhac
La'aanta PTFE ee ku dhawaad dhammaan gaasaska iyo dareerayaasha u dhexeeya -320 °F iyo +450 °F waa mid ka mid ah sifooyinkeeda ugu quruxda badan marka lagu isticmaalo nidaamyada xirmooyinka O-Ring.Daacadnimada PTFE waa la dhimi doonaa oo keliya marka ay taabato biraha alkaliinka ah ee dhalaalay iyo qaar ka mid ah xeryahooda halogenated.PTFE waa shayga la doortay si loo hubiyo iswaafajinta shaabada O-ring oo leh dhexdhexaad shaabadaysan ama lagu xidho heerkul balaadhan.
Tilmaamaha Naqshadeynta ee PTFE O-Rings
Dhaqanka caagga ah ee O-Ring-ka caadiga ah sida Per MIL-G-5514 ayaa sida caadiga ah lagula taliyaa haddii ay dhacdo rakibaadyo nooca cadaadiska ah ee codsiyada firfircoon.TG O-Rings sidoo kale waxaa loo isticmaali karaa codsiyo gaar ah.Maaddaama kala duwanaanshaha jireed ee PTFE iyo xeryahooda elastomeric ay aad u sarreeyaan, qaabaynta soo socota iyo hababka rakibaadda ayaa bixin doona natiijooyinka xidhitaanka ugu wanaagsan ee suurtogalka ah marka la eego waxqabadka iyo nolosha shaabadda:
- Si ka duwan sida O-Rings-ka caagga ah, PTFE O-Rings ma la kulmaan guul-darrooyin wareeg ah, markaa waxaa suurtagal ah in la yareeyo ballaca qanjirka.
- PTFE O-Rings ma laha is waafajinta O-Rings caag ah;sidaas darteed waxaa lagama maarmaan ah in la yareeyo tuujin iskutallaab ah oo u dhiganta midka loo cayimay caag si loo fududeeyo isu imaatinka.
Talooyinka Rakibaadda ee polymer O-Rings
Ka ilaalinta PTFE O-Rings in la ninaaxo ama la gooyo inta lagu jiro rakibidda waa muhiim.Gouging wuxuu dhici karaa marka la iskula bixinayo O-rings garbaha fiiqan ama dunta.Waxaa lagaga fogaan karaa in giraangiraha lagu dhejiyo meelo fiiqan iyadoo la isticmaalayo qalab ama bixinta geesaha ama radiyada.Kala bixin dhexdhexaad ah, haddii ay suurtagal tahay in ka hooseeya 10%, ayaa lagula talinayaa inta lagu jiro rakibidda O-ring.Isticmaalka saliidda kulul ama biyaha qubeyska ayaa sahlaysa fiditaanka weyn ee loo baahan yahay.Isbeddellada naqshadeynta ama hababka gaarka ah ayaa laga yaabaa in looga baahdo xaaladaha fidsan in ka badan 20%.
PTFE waxay u nugul tahay inay gurguurto sida dhammaan heerkulbeegyada.Sifadan waxay u baahan tahay in wax laga qabto si looga fogaado luminta culayska daboolka.Waxaa suurtagal ah in la hagaajiyo saameynta socodka qabowga iyadoo la bedelayo cabbirrada sida lagu taliyay jaantusyada.
PTFE O-ringings waxaa laga soo saari karaa iskudhisyo kala duwan sida PTFE-garaaf-buuxsan, bronze iyo galaas.Inta badan, shuruudaha waxaa lagu buuxin karaa PTFE oo aan buuxin.
Faa'iidooyinka PTFE O-Rings
- O-Rings waa mid ka mid ah xalalka ugu fiican ee nidaamyada cadaadiska hooseeya
- Waafaqsanaanta kiimikada caalamiga ah ee PTFE
- Heerkul ballaadhan oo u dhexeeya -320 °F iyo +500 °F
- Sicir degdeg ah iyo soo jeedid degdeg ah
- Doorashada cabbirka ballaaran ee O-Rings inta u dhaxaysa 0.110 "iyo ~ 40";cabbir gaar ah ayaa la heli karaa marka la codsado
- Faakiyum ilaa cadaadis-sare, marka lala isticmaalo giraanta dib-u-celinta ku habboon
