PTFE Coated O-Rings Applications
Aegis, Aflas, Butyl, Fluorosilicone, Hypalon kana chero komisheni yako chaiyo application ingangoda.Yakaputirwa uye Yakavharidzirwa O-Rings ndeimwe sarudzo zvakare:
- Yakaputirwa kana Yakavharwa - Yakaputirwa O-Rings ndeye PTFE yakavharwa, neiyo yekunamatira inonamatira kuO-Ring (kazhinji Silicone kana Viton kana NBR).Yakavharirwa O-Rings iO-Ring (kazhinji Silicone kana Viton) yakavharwa nePTFE chubhu.PTFE coating yeO-Rings ndeye yakanakira yakaderera-kukwesha coating uko kushanda kuchinjika kuri kutariswa kukuru.Iyo yakavharidzirwa O-Ring inoita kunge yakakwira viscous fluid, chero kudzvanywa pachisimbiso kunofambiswa kwese kwese.Yakavharwa O-Rings inowanikwa mumhando dzakasiyana dzemavara.
- Special makomisheni ezvishandiso - Kana iwe uine chinodiwa kune chaiyo komisheni isiri iyo yakajairwa indasitiri chiyero, tinogona kushanda nevagadziri kugadzira iyo chaiyo komboni kuti isangane nezvido zvako.
- Mil-Spec, Mil-Std kana Milspecs chiyero cheUnited States chekudzivirira chinoshandiswa kuzadzisa zvinangwa zvekumira neDhipatimendi reDziviriro reUS.Rockets Seals inogona kuunza chero Mil-Spec kuburikidza netiweki yedu yakakura yevane mukurumbira vatengesi.
- FDA chikafu giredhi zvinhu, mazita ekunze, USP, KTW, DVGW, BAM, WRAS (WRC), NSF, Underwriters Laboratories (UL), Aerospace (AMS) uye Mil-Spec - Rocket ine ruzivo nekuzadzisa zvaunoda pane ese maindasitiri zviyero.
unogona kusarudza kutevera ruvara kana rumwe rumwe ruvara.
Kuzivikanwa zviri nani nezita remhando yeTeflon, polytetrafluoroethylene (PTFE) inopa nzvimbo isingabatike kune cookware, polish yezvipikiri, maturusi ekugadzira bvudzi, jira/kapeti kurapwa, uye mashizha ekupukuta mhepo.Nekudaro, vagadziri vari kuona mabhenefiti akawedzerwa kubva pakushandisa PTFE senzira yekugadzira mhando yeO-rings.O-mheteyakavakwa uchishandisa PTFE inopa yakanyanya kupisa uye makemikari insulation, uye vanogona kuramba kukweshera nemvura zvakare.
PTFE VERSUS TEFLON
Kunyangwe ivo vachisiyana mukumaka, PTFE neTeflon vanogovana zvakaenzana mabviro uye zvivakwa.
PTFE
PTFE ipolymer yakagadzirwa kubva mumakemikari bonding pakati pekabhoni nefluorine, ichitora mukana wemahara radicals 'maitiro eku polymerize ne tetrafluoroethylene.Nyaya iyi yakawanikwa netsaona muna 1938, apo nyanzvi yekemisitiri yeDuPont Roy J. Plunkett akaedza kugadzira rudzi rutsva rwefiriji, uye akasanganisa zvinhu izvi pamwechete asingazive kuti zvaizokonzeresa sei.
TEFLON
Kinetic Chemicals, kambani yekudyidzana pakati peDuPont neGeneral Motors, yakatengesa PTFE pasi pezita rechiratidzo Teflon muna 1945. Muchidimbu, Teflon iPTFE.Nekudaro, PTFE inowanikwawo pasi peakasiyana mamwe mazita emhando, akadai se:
- Daikin-Polyflon
- Fluon
- Dyneon
PROPERTIES
Zvizhinji zvivakwa zvinosiyanisa PTFE kubva kune zvimwe zvinhu, zvinosanganisira:
- Low friction coefficient: PTFE ine yechitatu yakaderera friction coefficient yechero chinhu chinozivikanwa nemunhu, zvichireva kuti ndizvo chaizvo.
- Mabasa patembiricha yakanyanyisa: Yakayerwa pa600 K, PTFE inonyunguduka pa327ºC kana 620ºF, uye inoshandawo nemazvo pakudziya kwakadzika se -268ºC kana −450ºF.
- Inoramba mvura: Mvura inonamira pamusoro pePTFE, zvichireva kuti nzvimbo dzakabatwa neichi chinhu chinoramba oxidation.
- Nonreactive: PTFE haibatike nehuwandu hwezvinhu zvinopisa, zvichiita kuti ive yakakodzera kushandiswa mumapombi, mavharuvhu, zvisimbiso, uye maO-ringing.
PTFE'S HIGH TEMPERATURE RANGE
The tembiricha range (-1,000F kusvika +4,000F), nonreactivity, mvura kuramba, uye yakaderera friction properties yePTFE inoita chinhu chakakodzera zvinhu kuvaka O-mhete kuti ishandiswe mune zvakasiyana siyana zvekushandisa.Zvivakwa izvi zvinoita kuti PTFE O-mhete ive sarudzo yakanaka kune inodzivirira mamiriro ekunze uye maapplication anosanganisira magetsi uye kupisa kwemafuta.
Nekuda kwekuwanda kwavo,PTFE O-zvindorihadzina "kunyungudutswa-kuumbwa" - pane kudaro, dzakatsikirirwa uye dzakasimwa kuti dzipe chimiro chinodiwa.
TEFLON/PTFE SEALS
O-mheteyakagadzirwa nePTFE iripo mune zvakasiyana-siyana zvemaindasitiri ekushandisa zvinoda zvisimbiso zvinogona kumira nenhamo.PTFE O-mhete inoonekwa mune akawanda maapplication anoratidzwa kune anotevera njodzi zvinhu:
