PTFE Coated O-Rings Applications

Aegis, Aflas, Butyl, Fluorosilicone, Hypalon kapena chilichonse chomwe mungafune kugwiritsa ntchito.Ma O-Ring Ophatikizidwa ndi Ophatikizidwa ndi njira inanso:

Zokutidwa kapena Zophimbidwa - Zokutidwa ndi O-Ring ndi PTFE zokutira, ndi zokutira kumamatira ku O-Ring (nthawi zambiri Silicone kapena Viton kapena NBR).Ma O-Ring Ophatikizidwa ndi O-Ring (kawirikawiri Silicone kapena Viton) yokutidwa ndi chubu cha PTFE.PTFE zokutira za O-Rings ndi zokutira zotsika zotsika bwino pomwe kusinthasintha kwa magwiridwe antchito ndikofunikira kwambiri.O-Ring yotsekedwa imakhala ngati madzi owoneka bwino kwambiri, kukakamiza kulikonse pa chisindikizo kumafalikira mbali zonse.Coated O-Rings amapezeka mumitundu yosiyanasiyana.
Zosakaniza zapadera za zipangizo - Ngati muli ndi zofunikira pamagulu enaake omwe sali ovomerezeka a makampani, tikhoza kugwira ntchito ndi opanga kuti apange gululo kuti likwaniritse zosowa zanu.
Mil-Spec, Mil-Std kapena Milspecs ndi mulingo wachitetezo ku United States womwe umagwiritsidwa ntchito kukwaniritsa zolinga zokhazikitsidwa ndi dipatimenti yachitetezo ku US.Rockets Seals amatha kupeza Mil-Spec iliyonse kudzera pagulu lathu lalikulu la ogulitsa odziwika.
Zakudya za FDA, mayina akunja, USP, KTW, DVGW, BAM, WRAS (WRC), NSF, Underwriters Laboratories (UL), Aerospace (AMS) ndi Mil-Spec - Rocket ili ndi chidziwitso pakukwaniritsa zosowa zanu pamiyeso yonse yamakampani.

mutha kusankha mtundu wotsatira kapena mtundu winanso.

Odziwika bwino ndi dzina la mtundu wa Teflon, polytetrafluoroethylene (PTFE) amapereka malo osakhazikika ku zophikira, zopukuta misomali, zida zokometsera tsitsi, kukonza nsalu/kapeti, ndi zopukutira zam'tsogolo.Komabe, opanga akuwona phindu lowonjezereka pogwiritsa ntchito PTFE ngati njira yopangira mphete za O-rings.O-mpheteyomangidwa pogwiritsa ntchito PTFE imapereka kutsekemera kwapamwamba kwamafuta ndi mankhwala, ndipo imatha kukana kukangana ndi madzi.

PTFE VERSUS TEFLON

Ngakhale amasiyana pakuyika chizindikiro, PTFE ndi Teflon amagawana chiyambi ndi katundu wofanana.

PTFE

PTFE ndi polima kupanga anachokera ku mankhwala kugwirizana pakati pa mpweya ndi fluorine, kutenga mwayi free radicals chizolowezi polymerize ndi tetrafluoroethylene.Zinthuzi zinapezeka mwangozi mu 1938, pamene katswiri wa mankhwala a DuPont Roy J. Plunkett anayesa kupanga mtundu watsopano wa firiji, ndikusakaniza zipangizozi pamodzi popanda kudziwa zomwe zingayambitse.

Mtengo wa TEFLON

Kinetic Chemicals, kampani yogwirizana pakati pa DuPont ndi General Motors, yotchedwa PTFE pansi pa dzina la Teflon mu 1945. Kwenikweni, Teflon ndi PTFE.Komabe, PTFE imapezekanso pansi pa mayina ena osiyanasiyana, monga:

Daikin-Polyflon
Fluon
Dyneon

ZINTHU

Zinthu zingapo zimasiyanitsa PTFE ndi zinthu zina, kuphatikiza:

Low friction coefficient: PTFE ili ndi chiwopsezo chachitatu chotsika kwambiri cha chinthu chilichonse chomwe chimadziwika ndi munthu, kutanthauza kuti ndichowonadi.
Ntchito pa kutentha kwambiri: Yoyezedwa pa 600 K, PTFE imasungunuka pa 327ºC kapena 620ºF, ndipo imagwiranso ntchito bwino pa kutentha kotsika -268ºC kapena -450ºF.
Imakana madzi: Madzi amapaka mikanda pamwamba pa PTFE, kutanthauza kuti malo omwe amagwiritsidwa ntchito ndi zinthuzi amakana makutidwe ndi okosijeni.
Nonreactive: PTFE sichita ndi unyinji wa zinthu dzimbiri, kupanga izo abwino ntchito mapaipi, mavavu, zisindikizo, ndi O-mphete.

KUSINTHA KWA PTFE KWAKUMWAMBA

Kutentha kosiyanasiyana (-1,000F mpaka +4,000F), nonreactivity, madzi kukana, ndi otsika mikangano katundu wa PTFE kupanga zinthu abwino kumanga O-mphete ntchito zosiyanasiyana ntchito.Zinthu izi zimapangitsa PTFE O-rings kukhala chisankho chabwino pamapulogalamu olimbana ndi nyengo komanso kugwiritsa ntchito magetsi ndi kutchinjiriza kwamafuta.

Chifukwa cha kuchuluka kwawo,PTFE O-mphetesali "osungunuka" - m'malo mwake, amapanikizidwa ndi sinter kuti apereke mawonekedwe ofunikira.

TEFLON/PTFE SEALS

O-mphetezopangidwa ndi PTFE zilipo mu ntchito zosiyanasiyana zamakampani zomwe zimafuna zisindikizo zomwe zimatha kupirira zovuta.PTFE O-rings amawonekera m'mapulogalamu ambiri omwe amakumana ndi zovuta zotsatirazi:

Top Mapulogalamu	Zofooka Zamakina
Kunja Mafuta Ma hydrocarbon Ma Acids Alkalis Zotsukira Mowa Ketoni Steam Mafiriji	Zisindikizo Zapamwamba za Vacuum Ma Flanges Osindikizira Ochepa a Vacuum Mpweya Wotentha Kwambiri
