Nkhani - FKM Rubber vs PTFE: Ndizinthu ziti zomwe zili ndi fluorinated |Malingaliro a kampani BESTEFLON

Fluorine rabara (Mtengo wa FKM) ndi thermosetting elastomer, pamene polytetrafluoroethylene (PTFE) ndi thermoplastic.Zonsezi ndi zida za fluorinated, zozunguliridwa ndi maatomu a fluorine ndi maatomu a carbon, zomwe zimawapangitsa kukhala osagwirizana ndi mankhwala.Munkhaniyi, yankho la TRP polima limafanizira zida ziwiri pakati pa FKM ndiPTFEkudziwa chomwe chiri chomaliza cha fluorinated ndikusankha chomalizaWopanga payipi wa PTFE

Ubwino wa FKM raba ndi PTFE

Zoyambira:

FKM: Ndege pa Nkhondo Yachiwiri Yapadziko Lonse idakhudzidwa ndi kutayikira kwa zisindikizo za nitrile, zomwe zinalibe kutentha kochepa komwe kumafunikira pakugwiritsa ntchito zosiyanasiyana.Kusakwanira kwa mankhwala a fluorocarbon bond kumatanthauza kuti fluorinated elastomers, kapena fluoroelastomers, ndi mapeto achilengedwe.Chifukwa chake mphira wa FKM adayamba kugulitsidwa mu 1948

PTFE: Mu 1938, wasayansi wa DuPont Roy Plancott anapeza polytetrafluoroethylene mwangozi.Plunkett anayesa mafiriji ndikuwasunga m’masilinda.Iye anadabwa kuti mipweya imeneyi inaunjikana, n’kusiya phula loyera, lomwe siligwirizana ndi mankhwala alionse ndipo limatha kupirira kutentha kwambiri.DuPont inalembetsa mtundu woyamba wa PTFE materials-ptfe mu 1945

Chigamulo: Kukula kwa PTFE ndikungochitika mwangozi, zomwe zidapangitsa kubadwa kwazinthu zodabwitsa.Komabe, chinthu chochititsa chidwi, FKM labala, chinali chofunikira kwambiri pazaka zankhondo.Pachifukwa ichi, mbiri yakale ya FKM fluoroelastomer ikutanthauza kuti ili bwinoko pang'ono pampikisano uwu.

Katundu:

FKM rabara: Labala ya FKM imakhala ndi zomangira zolimba za carbon-fluorine, zomwe zimapangitsa kuti ikhale yamankhwala kwambiri, yosamva kutentha komanso yosamva oxidation.FKM ili ndi chiwerengero chosiyana cha carbon-hydrogen bond (kulumikizana ndi kutentha kochepa komanso kukana kwa mankhwala), komabe imakhala ndi mphamvu yotsutsa mankhwala kuposa ma elastomer ena ambiri.

PTFE: Polytetrafluoroethylene imapangidwa ndi ma atomu a carbon, okhala ndi ma atomu awiri a fulorini pa atomu iliyonse ya carbon.Ma atomu awa a fulorini amazungulira unyolo wa kaboni kuti apange molekyulu wandiweyani wokhala ndi chomangira champhamvu kwambiri cha carbon-fluorine ndi kapangidwe ka polima, kupanga PTFE inert kumankhwala ambiri.

Chigamulo: Kutengera kapangidwe kake ka mankhwala, PTFE ilibe ma bond a carbon-hydrogen, zomwe zimapangitsa kuti ikhale yopanda mphamvu kuposa FKM (ngakhale FKM ikadali yolimbana ndi mankhwala modabwitsa).Pachifukwa ichi, PTFE ndi mthunzi chabe wa FKM kuzungulira uku

Ubwino:

FKM:

Kutentha kwakukulu (-45°C-204°C)

Wabwino kukana mankhwala

Kuchulukana kwakukulu, mawonekedwe abwino

Zabwino zamakina katundu

Itha kupangidwa kuti iwononge kuphulika, CIP, SIP

PTFE:

Kukana kutentha kwakukulu (-30°C mpaka +200°C)

Opanda mankhwala

Kusungunula kwabwino kwamagetsi

Kuzizira kwambiri komanso kupirira kutentha

Zosamatira, zopanda madzi

Coefficient of friction ndi yaying'ono kwambiri pakati pa zolimba zonse

Chigamulo: Sizingatheke kuwalekanitsa kuzungulira uku.FKM imapereka kukana kwakukulu kwa kutentha, koma sikufika pakuchita kwa PTFE ponena za kukana kwa mankhwala.Ndipo PTFE ndi yochepa kutentha zosagwira, koma amapereka njira zambiri sanali zomatira katundu

Zoyipa:

FKM:

Kodi idzatupa mu zosungunulira za fluorinated?

Sangagwiritsidwe ntchito ndi zitsulo zosungunuka kapena mpweya wa alkali

Mtengo wake ndi wapamwamba kuposa ma non-fluorocarbons ena

Kusankha FKM yolakwika pakugwiritsa ntchito kungayambitse kulephera mwachangu

Kutsika kwa kutentha kumatha kukhala okwera mtengo

PTFE:

Mphamvu zochepa ndi kuuma

Sizingasungunuke kukonzedwa

Kukana kwa radiation

Kuuma kwa High Shore kumapangitsa PTFE kukhala yovuta kusindikiza

Ptfe o-rings ali ndi kutayikira kwakukulu kuposa ma elastomer ena

Kusakhazikika kumapangitsa kuyika kwa zisindikizo zingapo kukhala kosatheka

Chigamulo: Nthawi zambiri, rabara ya FKM yapambana mpikisanowu ndi mphamvu zake zapamwamba, kusinthasintha komanso kusindikiza.Inde, ngati palibe koma chisindikizo cha inert mankhwala sichikwanira, ndiye kuti PTFE ndi chisankho chabwino.Komabe, FKM imapereka kusinthasintha kochulukira mbali zonse!

Mapulogalamu:

FKM:

Zagalimoto

Chemical processing

Mafuta ndi gasi

Makina apamwamba kwambiri

Zamlengalenga

Ena ambiri

PTFE:

Zida zopangira mankhwala

Mavavu

Chemical transport

Pampu diaphragms

Chigamulo: Ndi nkhondo ina yakupha!FKM ili ndi mapulogalamu ambiri, ndipo itha kugwiritsidwa ntchito kuzinthu zina zolemetsa kwambiri.Komabe, ngakhale zoperewera zake, zida za PTFE zimapereka njira yothetsera zovuta kwambiri zomwe zimaphatikizapo kuthamanga kwambiri, kutentha ndi mankhwala owononga.

Mtengo:

FKM rabara ndi chinthu chamtengo wapatali chifukwa cha kapangidwe kake ka mankhwala komanso kukana kwa mankhwala.Ngati simuganizira za mankhwala ndi kukana kutentha, mukhoza kusankha elastomer yotsika mtengo.

PTFE: Zinthu za PTFE ndizinthu zapamwamba kwambiri.Momwemonso, ngati kutentha, kupanikizika, ndi mankhwala owononga omwe akukhudzidwa ndi ntchito yanu sizikupitirira zomwe zavuta kwambiri, ndiye kuti njira zina zotsika mtengo zingakhale zofunika.Kuti mupeze ntchito yabwino yosindikizira, PTFE imamangiriridwa ku phata la elastomer kuti ipereke kukana kosindikiza.

Chigamulo: FKM ndi PTFE ndi zinthu zapamwamba kwambiri pazifukwa zomveka.Zida zonsezi zili ndi katundu wapadera, zomwe zimalongosola mtengo wopangira.Komabe, muyenera kukumbukira kuti pakugwiritsa ntchito kwambiri, onse amapereka mawonekedwe apadera.Pankhaniyi, mumapeza zomwe mumalipira, ndipo njira zotsika mtengo nthawi zambiri zimalephera msanga.Izi ndizolakwika zachuma.

Zotsatira: Nthawi zambiri, kusinthasintha kwa FKM kumapereka mwayi pa mpikisano wongoyerekeza uwu.Pamapeto pake, zida zonsezi zokhala ndi fluorinated zimapereka kukana kwapadera kwamankhwala komanso kukana kutentha.Komabe, monga pulasitiki, PTFE ndi yolimba kuposa FKM;kupanga kukhala koyenera kwambiri kusindikiza ntchito kwambiri komwe kupanikizika kwambiri ndi mankhwala owononga ndizovuta kwambiri.Kugwiritsa ntchito kwa FKM ngati chosindikizira kwatsimikizira kupambana kwake!

Tikukhulupirira kuti kufananitsa uku kwa rabala wa FKM ndi PTFE kukupatsani kumvetsetsa kwamitundu yosiyanasiyana yazinthu zilizonse.Ndikoyenera kutsindika kuti njira yabwino kwambiri yosankhira zinthu zoyenera kwambiri pazomwe mungagwiritse ntchito ndikulankhula ndi katswiri yemwe angakuuzeni magiredi osiyanasiyana azinthu ndikufananiza yankho loyenera la pulogalamu yanu.

Zomwe zili pamwambazi ndi zoyambira za FKM ndi PTFE, ndikukhulupirira kuti nkhaniyi ingakuthandizeni, tikuchokera ku China akatswiri.PTFE ogulitsa payipi, welcome to consult our products and please freely contact us at sales 02@zx-ptfe.com
