Izindaba - I-FKM Rubber vs PTFE: Iyiphi into yokugcina eyenziwe nge-fluorinated |I-BESTEFLON

Irabha ye-fluorine (I-FKM) i-thermosetting elastomer, kuyilapho i-polytetrafluoroethylene (PTFE) iyi-thermoplastic.Zombili ziyizinto ezinamakhemikhali, zizungezwe ama-athomu e-fluorine ngama-athomu ekhabhoni, okuwenza amelane ngendlela emangalisayo namakhemikhali.Kulesi sihloko, isixazululo se-polymer ye-TRP siqhathanisa izinto ezimbili phakathi kwe-FKM neI-PTFEukunquma ukuthi iyiphi impahla yokugcina ene-fluorinated bese ukhetha okokugcinaUmkhiqizi wepayipi le-PTFE

Izinzuzo zerabha ye-FKM ne-PTFE

Umsuka:

I-FKM: Izindiza phakathi neMpi Yezwe II zahlushwa ukuvuza kwezigxivizo ze-nitrile, ezazintula ukusebenza okuphansi kwezinga lokushisa elidingekayo ekusetshenzisweni okuhlukahlukene.Ukungangeni kwamakhemikhali kwamabhondi e-fluorocarbon kusho ukuthi ama-elastomers ane-fluorinated, noma ama-fluoroelastomers, ayisiphetho esingokwemvelo.Ngakho-ke irabha ye-FKM yaqala ukuthengiswa ngo-1948

I-PTFE: Ngo-1938, usosayensi waseDuPont uRoy Plancott wathola i-polytetrafluoroethylene ngengozi.UPlunkett wazama iziqandisi futhi wazifaka kumasilinda.Wamangala lapho la magesi anqwabelana, ashiya into emhlophe enengcina, engahlangani nanoma yiziphi izinto zamakhemikhali futhi ekwazi ukumelana namazinga okushisa aphakeme kakhulu.I-DuPont yabhalisa uhlobo lokuqala lwe-PTFE materials-ptfe ngo-1945

Isinqumo: Ukuthuthukiswa kwe-PTFE kuwukuqondana kwesiphetho esithakazelisayo, okwaholela ekuzalweni kwento engavamile.Kodwa-ke, into ehlaba umxhwele ngokulinganayo, irabha ye-FKM, yayidingeka ngokuphelele eminyakeni yempi.Ngalesi sizathu, umnikelo womlando we-FKM fluoroelastomer usho ukuthi ingcono kancane kulo mjikelezo womncintiswano.

Izakhiwo:

Irabha ye-FKM: Irabha ye-FKM iqukethe amabhondi e-carbon-fluorine aqinile, ayenza ibe ngamakhemikhali amaningi, imelana nokushisa futhi imelana ne-oxidation.I-FKM iqukethe inani elihlukile lamabhondi e-carbon-hydrogen (ukuxhumana nokushisa okubuthakathaka nokumelana namakhemikhali), kodwa isenokumelana namakhemikhali okuqinile kunamanye ama-elastomer amaningi.

I-PTFE: I-Polytetrafluoroethylene yakhiwe iketango lama-athomu ekhabhoni, nama-athomu amabili e-fluorine ku-athomu yekhabhoni ngayinye.Lawa ma-athomu e-fluorine azungeza iketango lekhabhoni ukuze akhe i-molecule ecinene enebhondi ye-carbon-fluorine eqinile kanye nesakhiwo se-polymer, okwenza i-PTFE ingene kumakhemikhali amaningi.

Isinqumo: Ngokusekelwe ngokuphelele ekwakhiweni kwawo kwamakhemikhali, i-PTFE ayinawo amabhondi e-carbon-hydrogen, okuyenza ingabi namakhemikhali amaningi kune-FKM (yize i-FKM isamelana namakhemikhali ngendlela emangalisayo).Ngalesi sizathu, i-PTFE isithunzi nje se-FKM kulo mzuliswano

Izinzuzo:

I-FKM:

Izinga lokushisa elibanzi (-45°C-204°C)

Ukumelana kwamakhemikhali okuhle kakhulu

Ukuminyana okuphezulu, ukuthungwa okuhle

Izakhiwo ezinhle zemishini

Ingabe ingalungiselelwa ukuwohloka kokuqhuma, i-CIP, i-SIP

I-PTFE:

Ukumelana okubanzi kwezinga lokushisa (-30°C kuya +200°C)

Inert ngamakhemikhali

I-insulation kagesi enhle kakhulu

Kubanda kakhulu futhi imelana nokushisa

Ayinamatheli, ingangeni manzi

I-coefficient of friction incane kakhulu kuzo zonke izinto eziqinile

Isinqumo: Akunakwenzeka ukubahlukanisa kulo mzuliswano.I-FKM inikeza ukumelana okukhulu kwezinga lokushisa, kodwa ayifinyeleli ekusebenzeni kwe-PTFE mayelana nokumelana namakhemikhali.Futhi i-PTFE ayizwani nokushisa kancane, kodwa inikeza izindlela eziningi zezakhiwo ezinganamatheli

Ububi:

I-FKM:

Ingabe izovuvukala ku-solvent ene-fluorinated?

Awukwazi ukusetshenziswa nezinsimbi ze-alkali ezincibilikisiwe noma ezinegesi

Izindleko ziphakeme kunamanye ama-non-fluorocarbons

Ukukhetha i-FKM engalungile yohlelo lokusebenza kungabangela ukwehluleka okusheshayo

Amazinga okushisa aphansi angabiza

I-PTFE:

Amandla aphansi nokuqina

Ayikwazi ukuncibilika kusetshenzwe

Ukungazweli kahle kwemisebe

Ubulukhuni be-High Shore benza i-PTFE kube nzima ukuyivala

I-Ptfe o-rings inezinga lokuvuza eliphakeme kunamanye ama-elastomer

I-inelasticity yenza ukufakwa kwezimpawu eziningi kungenzeki

Isinqumo: Ngokuvamile, irabha ye-FKM iwine lo mjikelezo wokuncintisana ngamandla ayo aphakeme, ukuguquguquka nekhono lokuvala.Yiqiniso, uma kungekho lutho ngaphandle kwe-chemically inert seal akwanele, khona-ke i-PTFE iyisinqumo esihle.Nokho, i-FKM inikeza ukuguquguquka okwengeziwe kuzo zonke izici!

Isinqumo: Enye impi ebulalayo!I-FKM inohlu olubanzi lwezinhlelo zokusebenza, futhi ingasetshenziswa kwezinye izinhlelo zokusebenza ezinzima ngempela.Kodwa-ke, naphezu kokulinganiselwa kwayo, izinto ze-PTFE zinikeza isisombululo esiphezulu sezinhlelo zokusebenza ezinzima kakhulu ezihilela ukucindezela okukhulu, izinga lokushisa kanye namakhemikhali agqwalayo.

Izindleko:

Irabha ye-FKM iwumkhiqizo ophambili ngenxa yokwakheka kwayo kwamakhemikhali kanye nokumelana namakhemikhali okwalandela.Uma ungacabangi izakhiwo zamakhemikhali nokumelana nokushisa, ungakhetha i-elastomer eshibhile.

I-PTFE: Impahla ye-PTFE nayo ingumkhiqizo wekhwalithi ephezulu.Ngokunjalo, uma izinga lokushisa, ingcindezi, namakhemikhali alimazayo abandakanyeka kuhlelo lwakho lokusebenza angeqi izimo ezimbi kakhulu, khona-ke ezinye izindlela ezishibhile zingafiseleka.Ukuze uthole ukusebenza okuhle kakhulu kokuvala, i-PTFE iboshelwe kumongo we-elastomer ukuze inikeze ukumelana nokucindezela.

Isinqumo: Kokubili i-FKM ne-PTFE yimikhiqizo yekhwalithi ephezulu ngezizathu ezinhle.Zombili lezi zinto zinezakhiwo ezikhethekile, ezichaza izindleko zokuzikhiqiza.Kodwa-ke, kufanele ukhumbule ukuthi ngezinhlelo zokusebenza ezidlulele, zombili zinikeza izici ezikhethekile.Kulokhu, uthola lokho okukhokhelayo, futhi ezinye izindlela ezishibhile zivame ukwehluleka ngokushesha.Lokhu ekugcineni umnotho ongalungile.

Umphumela: Ngokuvamile, ukuguquguquka kwe-FKM kuyinikeza inzuzo kulo mjaho wokucatshangelwa.Ekugcineni, zombili lezi zinto ezine-fluorinated zinikeza ukumelana okukhethekile kwamakhemikhali kanye nokumelana nokushisa.Nokho, njengepulasitiki, i-PTFE iqinile kune-FKM;ukuyenza ifaneleke kuphela ukufakwa uphawu okwedlulele kakhulu lapho umfutho ophezulu kanye namakhemikhali agqwalayo kuwukukhathazeka okuyinhloko.Ukusebenza okubanzi kwe-FKM njengempahla yokuvala sekuqinisekisile ukunqoba kwayo!

Sithemba ukuthi lokhu kuqhathaniswa kwerabha ye-FKM ne-PTFE kuzokunikeza ukuqonda okungcono kwezimpawu ezahlukahlukene zento ngayinye.Kufanele kugcizelelwe ukuthi indlela engcono kakhulu yokukhetha impahla efaneleke kakhulu yesicelo sakho ukukhuluma nochwepheshe ongakutshela amamaki ezinto ahlukahlukene futhi aqondanise nesixazululo esifanele sohlelo lwakho lokusebenza.

Okungenhla kumayelana nesingeniso sokuqukethwe okuhlobene ne-FKM ne-PTFE, ngithemba ukuthi lesi sihloko singakusiza, sivela e-China professional.PTFE hose abahlinzeki, welcome to consult our products and please freely contact us at sales 02@zx-ptfe.com
