Fluorine reberi (FKM) ni thermosetting elastomer, mugihe polytetrafluoroethylene (PTFE) ni thermoplastique.Byombi ni ibikoresho bya fluor, bikikijwe na atome ya fluor na atome ya karubone, bigatuma irwanya imiti idasanzwe.Muri iyi ngingo, igisubizo cya TRP polymer kigereranya ibikoresho bibiri hagati ya FKM naPTFEkugirango umenye aribintu bya fluor byanyuma hanyuma uhitemo ibya nyumaUruganda rwa PTFE
Inyungu za reberi ya FKM na PTFE
Inkomoko:
FKM: Indege mu Ntambara ya Kabiri y'Isi Yose yaranzwe no kumeneka kashe ya nitrile, itari ifite imikorere y’ubushyuhe buke isabwa mu bikorwa bitandukanye.Imiti idahwitse ya fluorocarbon isobanura ko elastomers ya fluor, cyangwa fluoroelastomers, ari umwanzuro usanzwe.Rber ya FKM rero yatangiye gucuruzwa mu 1948
PTFE: Mu 1938, umuhanga wa DuPont Roy Plancott yavumbuye polytetrafluoroethylene ku bw'impanuka.Plunkett yagerageje na firigo hanyuma ayibika muri silinderi.Icyamutangaje ni uko imyuka yegeranijwe, igasiga inyuma ibishashara byera, bidakora ibintu byose bya shimi kandi bishobora kwihanganira ubushyuhe bwinshi cyane.DuPont yanditse igitabo cya mbere cyibikoresho bya PTFE-ptfe mu 1945
Icyemezo: Iterambere rya PTFE ni impanuka yibintu bishimishije, byatumye havuka ibintu bidasanzwe.Ariko, ibikoresho bitangaje, FKM rubber, byari nkenerwa rwose mumyaka yintambara.Kubera iyo mpamvu, umusanzu wamateka ya FKM fluoroelastomer bivuze ko ari byiza gato muriki cyiciro cyamarushanwa
Ibyiza:
Rubber ya FKM: reberi ya FKM irimo karuboni-fluor ikomeye, bigatuma ikora cyane, irwanya ubushyuhe kandi irwanya okiside.FKM ikubiyemo umubare utandukanye wa karuboni-hydrogène ihuza (isano nubushyuhe buke hamwe nubushakashatsi bwimiti), ariko iracyafite imiti irwanya imiti kurusha abandi ba elastomers.
PTFE: Polytetrafluoroethylene igizwe numurongo wa atome ya karubone, hamwe na atome ebyiri za fluor kuri buri atome ya karubone.Izi atome za fluor zizengurutse urunigi rwa karubone kugirango zibe molekile yuzuye ifite karuboni-fluor ikomeye cyane hamwe na polymer, bigatuma PTFE yinjiza imiti myinshi
Icyemezo: Ukurikije gusa imiterere yabyo yimiti, PTFE ntaho ihuriye na karubone-hydrogène, ituma itagira imiti irenze FKM (nubwo FKM irwanya imiti idasanzwe).Kubwiyi mpamvu, PTFE nigicucu cya FKM muriki cyiciro
Ibyiza:
FKM:
Ubushyuhe bwagutse (-45 ° C-204 ° C)
Kurwanya imiti nziza cyane
Ubucucike buri hejuru, imiterere myiza
Ibikoresho byiza bya mashini
Irashobora gutegurwa guturika guturika, CIP, SIP
PTFE:
Kurwanya ubushyuhe bwagutse (-30 ° C kugeza + 200 ° C)
Inert
Amashanyarazi meza cyane
Ubukonje bukabije nubushyuhe
Kudafatana, kutagira amazi
Coefficient de friction niyo ntoya mubikomeye byose
Icyemezo: Ntibishoboka kubatandukanya iki cyiciro.FKM itanga ubushyuhe bwinshi, ariko ntabwo igera kumikorere ya PTFE mubijyanye no kurwanya imiti.Kandi PTFE ntishobora kwihanganira ubushyuhe buke, ariko itanga inzira nyinshi zumutungo udafatika
Ibibi:
FKM:
Bizabyimba mumashanyarazi ya fluor?
Ntushobora gukoreshwa nicyuma gishongeshejwe cyangwa gaze ya alkali
Igiciro kiri hejuru yizindi zitari fluorocarbone
Guhitamo FKM itari yo kubisabwa birashobora gutera kunanirwa byihuse
Impamyabumenyi yo hasi irashobora kubahenze
PTFE:
Imbaraga nke no gukomera
Ntishobora gushonga
Imirasire idahwitse
Gukomera kwa Shore muremure bituma PTFE igorana kashe
Ptfe o-impeta ifite umuvuduko mwinshi kuruta abandi ba elastomers
Inelastique ituma gushiraho kashe nyinshi bidashoboka
Icyemezo: Muri rusange, reberi ya FKM yatsinze iki cyiciro cyamarushanwa n'imbaraga zayo zisumba izindi, guhinduka no gufunga kashe.Birumvikana, niba ntakindi uretse kashe ya chimique inert idahagije, noneho PTFE ni amahitamo meza.Ariko, FKM itanga ibintu byoroshye guhinduka muburyo bwose!
Porogaramu:
FKM:
Imodoka
Gutunganya imiti
Amavuta na gaze
Imashini ziremereye
Ikirere
Abandi benshi
PTFE:
Ibikoresho byo gutunganya imiti
Indangagaciro
Gutwara imiti
Pompe diaphragms
Icyemezo: Ni indi ntambara yica!FKM ifite intera nini ya porogaramu, kandi irashobora gukoreshwa kuri bimwe biremereye cyane.Nubwo, nubwo ifite aho igarukira, ibikoresho bya PTFE bitanga igisubizo cyibanze kubikorwa bigoye birimo umuvuduko ukabije, ubushyuhe n’imiti yangiza
Igiciro:
FKM reberi nigicuruzwa cyiza cyane kubera imiterere yimiti hamwe nubushakashatsi bwimiti.Niba udasuzumye imiterere yimiti nubushyuhe bwubushyuhe, urashobora guhitamo elastomer ihendutse.
PTFE: Ibikoresho bya PTFE nabyo nibicuruzwa byujuje ubuziranenge.Mu buryo nk'ubwo, niba ubushyuhe, umuvuduko, hamwe n’imiti yangirika bigira uruhare mu gusaba kwawe bitarenze ibibazo bikabije, noneho ubundi buryo buhendutse bushobora kuba bwiza.Kugirango ubone imikorere myiza yo gufunga, PTFE ihujwe na elastomer yibanze kugirango itange compression.
Urubanza: Byombi FKM na PTFE nibicuruzwa byujuje ubuziranenge kubwimpamvu nziza.Ibyo bikoresho byombi bifite ibintu byihariye, bisobanura ikiguzi cyo kubibyaza umusaruro.Ariko, ugomba kwibuka ko kubisabwa bikabije, byombi bitanga ibintu byihariye.Muri iki kibazo, ubona ibyo wishyuye, kandi ubundi buryo buhendutse burigihe birananirana vuba.Ubu ni ubukungu butari bwo.
Igisubizo: Muri rusange, ihinduka rya FKM ritanga akarusho muri iri siganwa rya hypothettike.Ubwanyuma, ibyo bikoresho byombi bya fluor bitanga imiti idasanzwe yo kurwanya imiti no kurwanya ubushyuhe.Ariko, nka plastiki, PTFE irakomeye kuruta FKM;kubikora bikwiranye gusa no gufunga bikabije aho umuvuduko mwinshi hamwe nimiti yangirika aribyo byibanze.Ikoreshwa ryinshi rya FKM nkibikoresho bifunga kashe, byemeje ko itsinze!
Turizera ko uku kugereranya reberi ya FKM na PTFE bizaguha kumva neza ibintu bitandukanye biranga buri kintu.Tugomba gushimangira ko inzira nziza yo guhitamo ibikoresho bikwiranye no gusaba kwawe nukuvugana ninzobere ishobora kukubwira amanota atandukanye yibikoresho kandi igahuza igisubizo cyiza kubyo usaba.
