Masale a O a Perfluoroelastomer (FFKM)
LINTLHA TSA SEHLAHISOA
Masale a O a Perfluoroelastomer (FFKM) a emela sehlohlolo sa theknoloji ea ho tiisa, a fana ka ts'ebetso e sa bapisoang le e 'ngoe libakeng tse hlokang boiteko bo boholo indastering. Masale ana a O a entsoe ka tlamo ea carbon-fluorine, e a fang botsitso bo ikhethang ba mocheso, oxidative le lik'hemik'hale. Sebopeho sena se ikhethang sa limolek'hule se tiisa hore masale a O a FFKM a ka mamella mecha ea phatlalatso e mabifi, e leng se etsang hore a tšepahale haholo bakeng sa lits'ebetso tse matla le tse sa fetoheng. A ka hanela ho bola ho tsoa linthong tse fetang 1,600 tsa lik'hemik'hale tse kang li-acid tse matla, li-alkali tse matla, li-solvents tsa organic, mouoane o phahameng haholo, li-ether, li-ketone, li-coolant, metsoako e nang le naetrojene, li-hydrocarbon, li-alcohol, li-aldehydes, li-furan le metsoako ea amino.
Likarolo tsa Bohlokoa tsa Li-O-Rings tsa FFKM
Leha mehele ea O ea perfluorocarbon (FFKM) le fluorocarbon (FKM) ka bobeli li sebelisoa lits'ebetsong tsa ho koala, li fapana haholo ka sebopeho sa tsona sa lik'hemik'hale le bokhoni ba tsona ba ts'ebetso.
Sebopeho sa Lik'hemik'hale: Mehele ea FKM O e entsoe ka thepa ea fluorocarbon 'me ka kakaretso e loketse ho sebelisoa ho fihlela ho 400°F (204°C). Li fana ka khanyetso e ntle ho mefuta e fapaneng ea lik'hemik'hale le maro empa li kanna tsa se mamelle maemo a feteletseng ka katleho joalo ka FFKM.
Tshebetso e Feteletseng ya Tikoloho: Di-O-ring tsa FFKM di etseditswe ditikoloho tse feteletseng. Bokgoni ba tsona ba ho sebetsa maemong a lehodimo le ho hanela mefuta e mengata ya dikhemikhale bo di etsa hore e be kgetho e kgethwang bakeng sa ditshebediso diindastering tse kang tsa difofane, tsa ho sebetsana le dikhemikhale le tsa tlhahiso ya di-semiconductor.
Mehopolo ea Litšenyehelo: Thepa ea FFKM e theko e boima ho feta FKM ka lebaka la ts'ebetso ea eona e phahameng le lits'ebetso tse ikhethileng tsa tlhahiso. Leha ho le joalo, matsete a FFKM O-rings a lokafatsoa ke bokhoni ba ona ba ho thibela ho hloleha ho hoholo le ho netefatsa ts'epo ea nako e telele lits'ebetsong tsa bohlokoa.
FFKM khahlanong le FKM: Ho Utloisisa Liphapang
Mokhoa oa ho Tiisa
Lesale la ED le sebetsa ho latela molao-motheo oa khatello ea mechine le khatello ea mokelikeli. Ha e kentsoe pakeng tsa li-flange tse peli tsa hydraulic fitting, boemo bo ikhethang ba Ring ea ED bo lumellana le libaka tse hokelanang, e leng se etsang hore ho be le tiiso ea pele. Ha khatello ea mokelikeli oa hydraulic e ntse e eketseha ka har'a sistimi, khatello ea mokelikeli e sebetsa ho Ring ea ED, e leng se etsang hore e atolohe ka mahlaseli. Katoloso ena e eketsa khatello ea ho kopana pakeng tsa Ring ea ED le libaka tsa flange, e ntlafatsa tiiso le ho lefella liphoso life kapa life tsa bokaholimo kapa liphoso tse nyane.
Ho Itšetleha le ho Ikamahanya le Maemo
E 'ngoe ea melemo ea bohlokoa ea Ring ea ED ke bokhoni ba eona ba ho itšehla thajana le ho itlhophisa. Moralo oa lesale o netefatsa hore le lula le le bohareng ba khokahano nakong ea ho kenngoa le ts'ebetso. Tšobotsi ena ea ho itšehla thajana e thusa ho boloka khatello e tsitsitseng ea ho kopana holim'a bokaholimo bohle ba ho koala, e fokotsa kotsi ea ho lutla ka lebaka la ho se lumellane hantle. Ho feta moo, bokhoni ba Ring ea ED ba ho ikamahanya le likhatello le mocheso tse fapaneng bo netefatsa ho tšepahala ha nako e telele le ts'ebetso e tsitsitseng, esita le maemong a ts'ebetso a feto-fetohang.
Ho Tiisa ka Matla Tlas'a Khatello
Litsamaisong tsa hydraulic tse nang le khatello e phahameng, bokhoni ba ED Ring ba ho koala ka matla tlas'a khatello bo bohlokoa haholo. Ha khatello ea mokelikeli e ntse e phahama, thepa ea thepa ea ED Ring e e lumella ho hatella le ho hola, e boloka tiiso e tiileng ntle le ho fetoha kapa ho tsoa. Bokhoni bona ba ho koala ka matla bo netefatsa hore ED Ring e lula e sebetsa nakong eohle ea ts'ebetso ea sistimi ea hydraulic, e thibela ho lutla ha mokelikeli le ho boloka ts'ebetso ea sistimi.
Litšebeliso tsa FFKM O-Rings
Thepa e ikhethang ea FFKM O-rings e etsa hore e be ea bohlokoa haholo liindastering tse 'maloa:
Tlhahiso ea Semiconductor: Li-O-ring tsa FFKM li sebelisoa likamoreng tsa vacuum le lisebelisoa tsa ts'ebetso ea lik'hemik'hale ka lebaka la ho se ntše ha tsona khase haholo le ho hanyetsa lik'hemik'hale haholo.
Lipalangoang tsa Lik'hemik'hale: Masale ana a O a fana ka litiiso tse tšepahalang liphaepheng le litankeng tsa polokelo, a thibela ho lutla le ho netefatsa polokeho.
Indasteri ea Nyutlelie: Li-O-ring tsa FFKM li sebelisoa li-reactor tsa nyutlelie le litsing tsa ts'ebetso ea mafura, moo ho hanyetsa ha tsona mahlaseling le mocheso o feteletseng ho leng bohlokoa.
Lifofane le Matla: Litšebelisong tsa lifofane, FFKM O-rings li sebelisoa lits'ebetsong tsa mafura le lisebelisoa tsa hydraulic, ha lefapheng la matla, li sebelisoa lifemeng tsa motlakase ho netefatsa botšepehi ba litiiso libakeng tse nang le khatello e phahameng le mocheso o phahameng.

Mehele ea O ea Perfluoroelastomer (FFKM) ke khetho e ntle ka ho fetisisa bakeng sa lits'ebetso tse hlokang boemo bo holimo ba ts'ebetso le ts'epo. Ka botsitso ba tsona bo ikhethang ba mocheso, khanyetso e felletseng ea lik'hemik'hale, le thepa e tlase ea ho tsoa ha khase, mehele ea O ea FFKM e etselitsoe ho ipabola libakeng tse thata ka ho fetisisa. Khetha Lihlahisoa tsa Seal tse Entsoeng ka Boenjiniere bakeng sa litlhoko tsa hau tsa FFKM O-ring 'me u be le phihlelo ea phapang eo boiphihlelo ba lilemo tse mashome le boitlamo ba boleng bo ka e etsang. Ikopanye le rona kajeno ho buisana ka litlhoko tsa hau tse ikhethileng le ho fumana hore na mehele ea rona ea O ea FFKM e ka ntlafatsa ts'ebetso le polokeho ea lits'ebetso tsa hau tsa indasteri joang.
