Fluorine rabha (FKM) is thermosetting elastomer, nepo polytetrafluoroethylene (PTFE) iri thermoplastic.Ose ari maviri zvinhu zvine fluorinated, akakomberedzwa nemaatomu efluorine nemaatomu ekabhoni, izvo zvinovaita kuti varambe makemikari.Muchinyorwa chino, iyo TRP polymer mhinduro inoenzanisa zvinhu zviviri zviri pakati peFKM nePTFEkuona kuti ndeipi yekupedzisira fluorinated zvinhu uye kusarudza yekupedzisiraPTFE hose mugadziri
Mabhenefiti eFKM rabha uye PTFE
Mabviro:
FKM: Ndege panguva yeHondo Yenyika II dzakatambudzwa nekudonha kwe nitrile zvisimbiso, izvo zvaishaya tembiricha yakaderera inodiwa kune akasiyana maapplication.Iyo kemikari inertness yefluorocarbon bonds inoreva kuti fluorinated elastomers, kana fluoroelastomers, mhedziso yechisikigo.Saka FKM rabha yakatanga kutengeswa muna 1948
PTFE: Muna 1938, musayendisiti weDuPont Roy Plancott akawana polytetrafluoroethylene netsaona.Plunkett akaedza mafiriji ndokuachengeta mumasirinda.Zvakamushamisa ndezvokuti magasi aya akaungana, achisiya chinhu chichena chine namo, chisingapindirani nechero makemikari uye chinogona kumira kutonhora kwakanyanya.DuPont yakanyoresa mhando yekutanga yePTFE zvinhu-ptfe muna 1945
Mutongo: Kuvandudzwa kwePTFE ndiko kusangana kwechiitiko chinonakidza, chakakonzera kuzvarwa kwechinhu chinoshamisa.Nekudaro, chinhu chinokatyamadza zvakaenzana, FKM rabha, yaive yakakosha mumakore ehondo.Nechikonzero ichi, mupiro wenhoroondo weFKM fluoroelastomer zvinoreva kuti zviri nani zvishoma mumutambo uyu wemakwikwi.
Properties:
FKM rabha: FKM rabha ine yakasimba kabhoni-fluorine zvisungo, zvichiita kuti ive yakanyanya makemikari, inodzivirira kupisa uye oxidation-inodzivirira.FKM ine huwandu hwakasiyana hwekabhoni-hydrogen zvisungo (kubatana nekusina kusimba kupisa uye makemikari kuramba), asi ichine yakasimba makemikari kuramba kupfuura mamwe akawanda elastomers.
PTFE: Polytetrafluoroethylene inoumbwa neketani yemaatomu ecarbon, ine maatomu maviri efluorine pane imwe neimwe kabhoni atomu.Aya maatomu efluorine anotenderedza kabhoni cheni kuita gobvu molecule ine yakasimba kwazvo kabhoni-fluorine bond uye chimiro chepolymer, zvichiita kuti PTFE inert kune akawanda makemikari.
Mutongo: Zvichienderana nezvakasiyana kemikari, PTFE haina kabhoni-hydrogen bond, izvo zvinoita kuti iwedzere kemikari inert kupfuura FKM (kunyangwe FKM ichiri kusagadzikana nemakemikari).Nechikonzero ichi, PTFE ungori mumvuri weFKM mukutenderera uku
Zvakanakira:
FKM:
Tembiricha yakakura (-45°C-204°C)
Excellent chemical resistance
High density, yakanaka kugadzirwa
Zvakanaka mechanical properties
Inogona kugadzirirwa kuputika decompression, CIP, SIP
PTFE:
Yakakura tembiricha kuramba (-30°C kusvika +200°C)
Kemikari inert
Yakanakisa magetsi ekudzivirira
Kunyanya kutonhora uye kudzivirira kupisa
Haina-adhesive, isina mvura
Iyo coefficient of friction ndiyo idiki pane zvese zvakaomarara
Mutongo: Hazvibviri kuvaparadzanisa kutenderera uku.FKM inopa hukuru hwekupisa kupisa, asi haisviki kuita kwePTFE maererano nemakemikari kuramba.Uye PTFE haina kupisa zvishoma, asi inopa nzira dzakawanda dzekusanamatira zvivakwa
Zvakaipa:
FKM:
Ichazvimba mune fluorinated solvent?
Haikwanise kushandiswa neyakanyungudutswa kana gasious alkali simbi
Mutengo wakakwira kupfuura mamwe asiri mafluorocarbons
Kusarudza FKM isiriyo yekushandisa kunogona kukonzera kutadza nekukurumidza
Low tembiricha mamakisi anogona kudhura
PTFE:
Simba rakaderera uye kuoma
Haikwanise kunyungudutswa
Kusasimba kwemwaranzi kuramba
High Shore kuoma kunoita kuti PTFE inetse kuisa chisimbiso
Ptfe o-mhete dzine chiyero chepamusoro chekudonha kupfuura mamwe ma elastomers
Inelasticity inoita kuti kuisirwa chisimbiso kwakawanda kusagoneke
Mutongo: Kazhinji, FKM rabha yakahwina kutenderera uku kwemakwikwi nesimba rayo repamusoro, kuchinjika uye kugona kuisa chisimbiso.Zvechokwadi, kana pasina chinhu kunze kwechisimbiso chemakemikari inert chisina kukwana, saka PTFE isarudzo yakanaka.Nekudaro, FKM inopa kuwedzera kuchinjika mune ese maficha!
Applications:
FKM:
Automotive
Chemical processing
Mafuta uye gasi
Heavy duty machines
Aerospace
Vamwe vakawanda
PTFE:
Chemical processing equipment
Mavharuvhu
Kutakura kwemakemikari
Pombi diaphragms
Mutongo: Ndiyo imwe hondo inouraya!FKM ine huwandu hwakawanda hwekushandisa, uye inogona kuiswa kune mamwe anorema chaizvo maapplication.Nekudaro, kunyangwe paine painogumira, PTFE zvinhu zvinopa mhinduro yekupedzisira kune yakanyanya kuoma maapplication inosanganisira yakanyanya kudzvanywa, tembiricha uye inoparadza makemikari.
Mutengo:
FKM rabha chigadzirwa chepamusoro nekuda kwekuumbwa kwayo kwemakemikari uye kunotevera makemikari kuramba.Kana iwe usingatarise makemikari zvimiro uye tembiricha kuramba, unogona kusarudza yakachipa elastomer.
PTFE: PTFE zvinhu zvakare chigadzirwa chemhando yepamusoro.Saizvozvo, kana tembiricha, kudzvanywa, uye makemikari ekuora anowanikwa muchikumbiro chako asingapfuure zvakanyanya zvakanyanya, saka dzimwe nzira dzakachipa dzinogona kudiwa.Kuti uwane yakanakisa yekuisa chisimbiso kuita, PTFE inosungirirwa kune elastomer musimboti kuti ipe compression kuramba.
Mutongo: Zvese FKM nePTFE zvigadzirwa zvemhando yepamusoro nezvikonzero zvakanaka.Zvose izvi zvinhu zvine zvinhu zvakakosha, izvo zvinotsanangura mari yekuzvigadzira.Nekudaro, iwe unofanirwa kuyeuka kuti kune yakanyanyisa maapplication, ese ari maviri anopa akakosha maficha.Muchiitiko ichi, iwe unowana zvaunobhadhara, uye dzimwe nzira dzakachipa dzinowanzokundikana nekukurumidza.Izvi zvinopedzisira hupfumi husina kunaka.
Mhedzisiro: Kazhinji, kushanduka kweFKM kunopa mukana mujaho rekufungidzira.Pakupedzisira, zvese zviri zviviri izvi fluorinated zvinhu zvinopa yakakosha makemikari kuramba uye tembiricha kuramba.Nekudaro, sepurasitiki, PTFE yakaoma kupfuura FKM;zvichiita kuti ive yakakodzera chete kune yakanyanya kuvharwa chisimbiso kunyorera uko kudzvanywa kwepamusoro uye makemikari anoparadza ndiyo inonyanya kunetseka.Kuwedzera kushanda kweFKM sechinhu chekuisa chisimbiso, zvakanaka, kwasimbisa kukunda kwayo!
Isu tinovimba kuti kuenzanisa uku kweFKM rabha uye PTFE kunokupa iwe kunzwisisa kuri nani kweakasiyana maitiro echimwe chinhu.Zvinofanira kusimbiswa kuti nzira yakanakisa yekusarudza yakanyatsokodzera zvinhu zvechikumbiro chako kutaura nenyanzvi inogona kukuudza magiredhi akasiyana ezvinyorwa uye kuenderana nemhinduro yakakodzera yekushandisa kwako.
Izvo zviri pamusoro ndezve FKM uye PTFE zvine chekuita nezvesumo, ndinovimba chinyorwa ichi chinogona kukubatsira, isu tinobva kuChina nyanzvi.PTFE hose vatengesi, welcome to consult our products and please freely contact us at sales 07@zx-ptfe.com
