Ntchito za PTFE Rod

Chithunzi cha PTFEMawonekedwe: Kutentha kogwiritsira ntchito ndikotambasula kwambiri (Celsius kuchokera -200 madigiri mpaka +260 madigiri);Anti-majority chemical substance's corrosiveness, kupatula ma fluoride ndi alkalinity moltenmetal;Makina abwino kwambiri, kukana kukalamba; Kukana kwamoto kwabwino kwambiri (Kugwirizana ndi mayeso a ASTM-D635 ndi D470), mumlengalenga kuti muwongoleredwe ngati zinthu zoletsa moto; Zotsika kwambiri; kuyamwa madzi……

PTFE-polytetrafluoroethylene inapezedwa ndi Dr. Roy Plunkett wa DuPont Research Laboratory pa April 6, 1938. PTFE yoyambirira inapangidwanso ndi Dupont ndipo inatulutsidwa ngati mankhwala mu 1945.

The mankhwala kwambiri kugonjetsedwa ndi dzimbiri mankhwala ndipo akhoza kupirira kutentha pamwamba 500 ° C. Chimodzi mwa zinthu PTFE woyamba kunyumba ndi "PTFE TACHIMATA Frying poto".Ngakhale mphika umagwira ntchito bwino kwambiri, ndi wosiyana ndi ndodo za PTFE ndi mbale zomwe timapereka.Amapopera pa zokutira pafupifupi wakuda, ndodo zoyera za PTFE ndi mapepala mu phukusi la PTFE lozungulira la nthunzi lamoto ndi loyera moyera momwe angagwiritsire ntchito ndodo zapulasitiki za PTFE momwe angagwiritsire ntchito mafakitale PTFE ndodo zapulasitiki PTFE gaskets ndi ma CD nthunzi.

Chifukwa PTFE imakhala ndi kutentha kwakukulu komanso kukana kwa mankhwala, nthawi zambiri imagwiritsidwa ntchito popanga ma valve.Kuchokera ku mavavu osavuta a nthunzi / madzi otentha mpaka kutentha kwambiri, mafakitale ogwiritsira ntchito madzimadzi a caustic chemical valves.Nkhaniyi ndi yokhazikika mpaka pulasitiki yolimba ndipo imatha kupangidwa mosavuta - imodzi mwazosavuta kugwiritsa ntchito pulasitiki.The PTFE ndodo akhoza machined mu kulolerana pafupi kwambiri pa ndodo ang'onoang'ono awiri awiri ndi awiri a +.002 "/ - .00".Kukana kwa Chemical ndi chimodzi mwazinthu zazikulu zomwe zimagwirizanitsidwa ndi zida.Mu flakes kapena flakes, PTFE ntchito ngati zinthu gasket kwa kutentha kwambiri ndi flanges mankhwala kugonjetsedwa ndi zisindikizo.
