PTFE Yashizweho O-Impeta
Niki PTFE Yashizweho O-Impeta
PTFE ikozweho O-impeta ni kashe igizwe na reberi gakondo ya O-ring (urugero, NBR, FKM, EPDM, VMQ) nka substrate ya elastique, hejuru ya firime yoroheje, imwe, kandi ifatanye neza ya polytetrafluoroethylene (PTFE). Iyi miterere ikomatanya ibyiza byibikoresho byombi, bikavamo imikorere idasanzwe.
Ibice byibanze byo gusaba
Bitewe nimiterere yihariye, O-impeta ya PTFE ikoreshwa cyane mubidukikije bisaba ibisabwa bidasanzwe:
Inganda n’inganda zikomoka kuri peteroli:
Gufunga indangagaciro, pompe, reaction, hamwe na flanges ya pipe ikora itangazamakuru ryangirika cyane nka acide ikomeye, alkalis ikomeye, okiside ikomeye, hamwe na solge organic.
Gufunga muri sisitemu yo gutanga imiti-isukuye cyane kugirango wirinde kwanduza.
Uruganda rwa farumasi n’ibinyabuzima:
Gufunga ibikoresho bitunganijwe bisaba isuku ihanitse, nta gutemba, kandi nta kwanduza (urugero, bioreactors, fermenters, sisitemu yo kweza, imirongo yuzuza).
Gufunga birwanya imiti ikarishye hamwe nubushyuhe bwo hejuru bukoreshwa muri CIP (Isuku-mu-mwanya) na SIP (Sterilize-mu-mwanya).
Inganda n'ibiribwa:
Ikidodo cyibikoresho byujuje FDA / USDA / EU amabwiriza yo guhuza ibiryo (urugero, ibikoresho byo gutunganya, ibyuzuza, imiyoboro).
Kurwanya ibiryo byo mu rwego rwogusukura hamwe nisuku.
Semiconductor & Electronics Inganda:
Ikidodo c'amazi ya ultrapure (UPW) hamwe na chimique-isukuye cyane (acide, alkalis, solvents) uburyo bwo gutanga no gutunganya ibintu, bisaba kubyara uduce duto cyane kandi ibyuma byangiza.
Ikidodo cyibyumba bya vacuum nibikoresho byo gutunganya plasma (bisaba gusohoka bike).
Inganda zitwara ibinyabiziga:
Gufunga ahantu h'ubushyuhe bwo hejuru nka sisitemu ya turbocharger na sisitemu ya EGR.
Ikidodo gisaba guterana amagambo hamwe no kurwanya imiti mukwirakwiza no gukoresha lisansi.
Porogaramu muri sisitemu nshya yimodoka ikonjesha.
Ikirere & Defence:
Ikidodo gisaba kwizerwa cyane, kurwanya ubushyuhe bukabije, no kurwanya ibicanwa bidasanzwe / hydraulic fluid muri sisitemu ya hydraulic, sisitemu ya lisansi, hamwe na sisitemu yo kugenzura ibidukikije.
Inganda rusange:
Ikidodo cya silinderi ya pneumatike na hydraulic isaba guterana amagambo make, kuramba, no kwambara birwanya (cyane cyane kumuvuduko mwinshi, umuvuduko mwinshi wo kwisubiraho).
Ikidodo cyimyanya itandukanye, pompe, hamwe na connexion bisaba kurwanya imiti nibintu bidafite inkoni.
Ikidodo cyibikoresho bya vacuum (bisaba gusohoka bike).
Inyungu zidasanzwe n'ibiranga imikorere
Inyungu yibanze ya PTFE ikozweho O-impeta iri mubikorwa byongerewe imbaraga biva mubikorwa byabo:
Ubusembwa budasanzwe bwa Shimi:
Imwe mu nyungu zibanze. PTFE igaragaza imbaraga zo kurwanya imiti hafi ya yose (harimo acide ikomeye, alkalis ikomeye, aqua regia, ibishishwa kama, nibindi), insimburangingo nyinshi zidashobora kugeraho zonyine. Ipitingi itandukanya neza itangazamakuru ryangirika imbere ya reberi yimbere, ikagura cyane O-ring ikoreshwa mubidukikije bikabije.
Coefficient nkeya cyane yo guterana amagambo (CoF):
Inyungu ikomeye. PTFE ifite imwe mu ndangagaciro za CoF mu bikoresho bizwi (mubisanzwe 0.05-0.1). Ibi bituma O-impeta itwikiriye neza muburyo bwo gufunga kashe (urugero, gusubiza inkoni ya piston, kuzunguruka):
Bigabanya cyane gutandukana no kwiruka.
Kugabanya ubushyuhe buterwa no guterana no kwambara.
Yagura ubuzima bwa kashe (cyane cyane mumuvuduko mwinshi, porogaramu nyinshi).
Kunoza imikorere ya sisitemu.
Ikoreshwa ryinshi ry'ubushyuhe:
Igifuniko cya PTFE ubwacyo gikomeza imikorere mu bushyuhe bwagutse cyane kuva kuri -200 ° C kugeza kuri + 260 ° C (igihe gito kugeza kuri + 300 ° C). Ibi byongerera cyane ubushyuhe bwo hejuru bwa reberi shingiro O-impeta (urugero, NBR shingiro isanzwe igarukira kuri ~ 120 ° C, ariko hamwe na PTFE ishobora gukoreshwa mubushyuhe bwinshi, bitewe na reberi yahisemo). Imikorere yubushyuhe buke nayo iremezwa.
Ibyiza Byiza Bidafatika hamwe no Kudahinduka:
PTFE ifite ingufu zo hasi cyane, bigatuma irwanya cyane gufatira hamwe no kudahumanya amazi n'amazi ashingiye kumavuta. Ibisubizo muri:
Kugabanya ububi, kokiya, cyangwa gufatira ibisigazwa byitangazamakuru hejuru yikimenyetso.
Gukora isuku byoroshye, cyane cyane bikwiranye ninzego zifite isuku nyinshi nkibiryo na farumasi.
Komeza gukora kashe hamwe nibitangazamakuru byijimye.
Isuku Ryinshi hamwe na Leachables:
Ubuso bworoshye, bwuzuye PTFE bugabanya kugabanuka kwingirangingo, inyongeramusaruro, cyangwa ibintu bifite uburemere buke bwa molekile. Ibi nibyingenzi mubikorwa byogukora cyane muri semiconductor, pharma, biotech, nibiribwa & ibinyobwa, birinda neza ibicuruzwa byanduye.
Kwambara neza:
Mugihe PTFE isanzwe irwanya kwambara ntabwo ari nziza, CoF yayo yo hasi cyane igabanya cyane igipimo cyo kwambara. Iyo uhujwe na reberi ikwiye (itanga inkunga no kwihangana) hamwe nubuso bukwiye bwo kurangiza / gusiga, O-impeta zometseho muri rusange zigaragaza kwihanganira kwambara neza kuruta reberi yambaye ubusa O-impeta zikoreshwa.
Imiti yongerewe imbaraga zo kurwanya imiti ya Rubber:
Ipitingi irinda reberi yimbere imbere yibitero byitangazamakuru, ituma hakoreshwa ibikoresho bya reberi bifite imiterere myiza (nka elastique cyangwa igiciro, urugero, NBR) mubitangazamakuru bisanzwe byabyimba, bikomeretsa, cyangwa bitesha agaciro reberi. Ikora neza "ibirwanisho" byoroshye bya rubber hamwe na PTFE irwanya imiti.
Guhuza Vacuum Nziza:
Ipfunyika ryiza cyane rya PTFE rifite ubucucike bwiza kandi risanzwe risohoka hanze, rifatanije nubushobozi bwimikorere ya reberi, bitanga kashe nziza.
3. Ibitekerezo by'ingenzi
Igiciro: Kurenza reberi isanzwe O-impeta.
Ibisabwa Kwishyiriraho: Saba gufata neza kugirango wirinde kwangiza igikoresho ukoresheje ibikoresho bikarishye. Ibikoresho byo kwishyiriraho bigomba kugira icyerekezo gihagije muri chamfers hamwe nubuso bwuzuye burangiye.
Uburinganire bwuzuye: Ubwiza bwa coating (adhesion, uburinganire, kubura pinholes) nibyingenzi. Iyo igifuniko cyacitse, reberi yagaragaye itakaza imbaraga zayo zo kurwanya imiti.
Gushiraho Gushiraho: Byibanze biterwa na rebero yatoranijwe. Igifuniko ubwacyo ntabwo gitanga imbaraga zo kwikuramo.
Ubuzima bwa Dynamic Service: Mugihe kiruta cyane reberi yambaye ubusa, igifuniko amaherezo kizashira mugihe kirekire, gisubirana cyane cyangwa kizunguruka. Guhitamo ibyuma byinshi birwanya kwambara (urugero, FKM) hamwe nigishushanyo mbonera gishobora kongera ubuzima.
Incamake
Agaciro shingiro ka PTFE ikozweho O-impeta iri muburyo uburyo igifuniko cya PTFE gitanga ubudahangarwa bwimiti, coefficient nkeya cyane yo guterana amagambo, ubushyuhe bwagutse, imiterere itari inkoni, isuku nyinshi, hamwe no kurinda insimburangingo kuri reberi gakondo O-impeta. Ni igisubizo cyiza cyo gusaba imbogamizi zirimo kwangirika gukomeye, isuku nyinshi, guterana gake, hamwe nubushyuhe bwinshi. Mugihe uhitamo, ni ngombwa guhitamo ibikoresho bya reberi ikwiye hamwe nibisobanuro bifatika ukurikije porogaramu yihariye (itangazamakuru, ubushyuhe, igitutu, imbaraga / static), kandi ukemeza neza ko ushyiraho kandi ukabungabunga kugirango ubungabunge uburinganire no gukora neza.
Imbonerahamwe ikurikira irerekana muri make ibintu byingenzi biranga hamwe na PTFE ikozweho O-impeta:
