Perfluoroelastomer (FFKM) O-Rings
LITLHAKISO TSE HLAHANG
Perfluoroelastomer (FFKM) O-rings e emela tlhōrō ea theknoloji ea ho tiisa, e fanang ka ts'ebetso e ke keng ea bapisoa le maemo a thata ka ho fetisisa a indasteri. Li-O-ring tsena li entsoe ka bond ea carbon-fluorine, e ba fang botsitso bo ikhethang ba mocheso, oxidative le lik'hemik'hale. Sebopeho sena se ikhethang sa limolek'hule se tiisa hore FFKM O-rings e ka mamella mecha ea litaba e mabifi, e etsa hore e be e ka tšeptjoang haholo bakeng sa likopo tse matla le tse tsitsitseng. E khona ho hanela ho bola ho tsoa ho lik'hemik'hale tse fetang 1,600 tse kang li-acid tse matla, li-alkalis tse matla, li-solvents, mouoane oa mocheso o phahameng haholo, li-ethers, ketone, li-coolants, metsoako e nang le naetrojene, li-hydrocarbon, joala, aldehydes, furans le metsoako ea amino.
Lintlha tsa bohlokoa tsa FFKM O-Rings
Le hoja li-ring tsa perfluorocarbon (FFKM) le fluorocarbon (FKM) O-ring li sebelisoa ha ho tiisoa likopo, li fapane haholo ka sebopeho sa tsona sa lik'hemik'hale le bokhoni ba ts'ebetso.
Sebopeho sa Lik'hemik'hale: Li-ring tsa FKM O-li entsoe ka thepa ea fluorocarbon 'me ka kakaretso li loketse ho sebelisoa ho fihlela ho 400°F (204°C). Ba fana ka khanyetso e ntle ho mefuta e fapaneng ea lik'hemik'hale le metsi empa ba ka 'na ba se ke ba mamella maemo a feteletseng ka katleho joaloka FFKM.
Ts'ebetso e Feteletseng ea Tikoloho: Li-rings tsa FFKM O li etselitsoe maemo a feteletseng. Bokhoni ba bona ba ho sebetsa ka mocheso o phahameng le ho hanela mefuta e mengata e fapaneng ea lik'hemik'hale bo ba etsa khetho e ratoang bakeng sa lits'ebetso indastering e kang ea sefofane, ts'ebetso ea lik'hemik'hale le tlhahiso ea li-semiconductor.
Litšenyehelo: Lisebelisoa tsa FFKM li turu ho feta FKM ka lebaka la ts'ebetso ea tsona e holimo le lits'ebetso tse ikhethang tsa tlhahiso. Leha ho le joalo, matsete a FFKM O-rings a lokafatsoa ke bokhoni ba bona ba ho thibela ho hlōleha ha tlokotsi le ho netefatsa ho tšepahala ha nako e telele lits'ebetsong tsa bohlokoa.
FFKM vs. FKM: Ho Utloisisa Liphapang
Mokhoa oa ho Tiisa
Ring ea ED e sebetsa ka molao-motheo oa khatello ea mochine le khatello ea metsi. Ha e kentsoe pakeng tsa li-flange tse peli tsa hydraulic fitting, profil e ikhethang ea angled ea ED Ring e lumellana le libaka tsa ho kopana, ho theha 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 etsa hore e hole ka matla. Katoloso ena e eketsa khatello ea khokahano lipakeng tsa Ring ea ED le bokaholimo ba flange, ho ntlafatsa tiiso le ho lefella liphoso leha e le life tsa holim'a metsi kapa ho se lumellane ho fokolang.
Boiketsi ba ho Ikemela le ho Itokisa
E 'ngoe ea melemo ea bohlokoa ea Ring ea ED ke bokhoni ba eona ba ho ikemela le ho inchafatsa. Moralo oa selikalikoe o tiisa hore o lula o le bohareng ka har'a ho kopanya nakong ea ho kenya le ho sebetsa. Sebopeho sena sa ho ikemela se thusa ho boloka khatello e tsitsitseng ea ho kopana sebakeng sohle sa tiiso, ho fokotsa kotsi ea ho lutla ka lebaka la ho se tsamaisane hantle. Ho feta moo, bokhoni ba ED Ring ba ho ikamahanya le likhatello le lithempereichara tse fapaneng bo netefatsa ts'epo ea nako e telele le ts'ebetso e tsitsitseng, esita le maemong a matla a ts'ebetso.
Ho Tiisa ka Matla Tlas'a Khatello
Lits'ebetsong tsa hydraulic tse nang le khatello e phahameng, bokhoni ba ED Ring ba ho tiisa ka matla tlas'a khatello bo bohlokoa. Ha khatello ea mokelikeli e ntse e phahama, thepa ea ED Ring e e lumella ho hatella le ho hola, ho boloka tiiso e tiileng ntle le ho holofala kapa ho tsoa. Bokhoni bona bo matla ba ho tiisa bo tiisa hore Ring ea ED e lula e sebetsa bophelong bohle ba ts'ebetso ea hydraulic system, ho thibela ho tsoa ha mokelikeli le ho boloka ts'ebetso ea sistimi.
Likopo tsa FFKM O-Rings
Thepa e ikhethang ea FFKM O-rings e etsa hore e be ea bohlokoa haholo liindastering tse 'maloa:
Semiconductor Manufacturing: FFKM O-rings e sebelisoa ka likamoreng tsa vacuum le lisebelisoa tsa ho sebetsana le lik'hemik'hale ka lebaka la ho fokotseha ha tsona le ho hanyetsa lik'hemik'hale tse ngata.
Lipalangoang tsa Lik'hemik'hale: Li-O-ring tsena li fana ka litiiso tse tšepahalang liphaepheng le litanka tsa polokelo, ho thibela ho lutla le ho netefatsa polokeho.
Indasteri ea Nyutlelie: Li-ring tsa FFKM O-rings li sebelisoa libakeng tsa nyutlelie le litsing tsa ho lokisa mafura, moo ho hanyetsanang ha tsona le mahlaseli le mocheso o feteletseng ho leng bohlokoa.
Lifofane le Matla: Lits'ebetsong tsa sefofane, li-rings tsa FFKM O-rings li sebelisoa tsamaisong ea peterole le lisebelisoa tsa hydraulic, ha li ntse li le lefapheng la matla, li sebelisoa ka limela tsa matla ho netefatsa botšepehi ba litiiso libakeng tse phahameng tsa khatello le mocheso o phahameng.

Perfluoroelastomer (FFKM) O-rings ke khetho ea mantlha bakeng sa lits'ebetso tse hlokang boemo bo holimo ba ts'ebetso le ts'epo. Ka botsitso ba bona bo ikhethang ba mocheso, khanyetso e felletseng ea lik'hemik'hale, le thepa e tlase ea ho tsoa, li-rings tsa FFKM O li etselitsoe ho ipabola libakeng tse thata ka ho fetisisa. Khetha Lihlahisoa tsa Engineered Seal bakeng sa litlhoko tsa hau tsa FFKM O-ring 'me u bone phapang eo lilemo tse mashome tsa botsebi le boitlamo ba boleng bo ka e etsang. Ikopanye le rona kajeno ho buisana ka litlhoko tsa hau tse khethehileng le ho fumana hore na li-rings tsa rona tsa FFKM O-ring li ka ntlafatsa ts'ebetso le polokeho ea lits'ebetso tsa hau tsa indasteri.
