Nkhani - Kodi PTFE imayimira chiyani

Polytetrafluoroethylene (PTFE), yomwe ndi mtundu wa mankhwala ambiri okhala ndi mamolekyulu, imakhala ndi kukhazikika kwabwino kwa mankhwala komanso kukana dzimbiri. Ndi imodzi mwa zinthu zabwino kwambiri zosagwirizana ndi dzimbiri padziko lonse lapansi masiku ano. Kupatula sodium ndi fluorine yosungunuka, imatha kupirira mankhwala ena onse. Sidzasintha ikawiritsidwa mu aqua regia. Imafalikira kwambiri m'zinthu zosiyanasiyana zomwe zimafuna kukana asidi, alkali ndi organic solvents), Kutseka, mafuta ambiri komanso osamamatira, kutchinjiriza kwamagetsi komanso kupirira bwino koletsa ukalamba, kukana kutentha kwambiri (kungagwire ntchito kutentha kwa +250℃ mpaka -180℃ kwa nthawi yayitali). Tsopano tiyeni tiwone bwino makhalidwe osiyanasiyana a chinthuchi ndi momwe chimagwiritsidwira ntchito.

payipi ya PTFEImapangidwa ndi kuponderezedwa kapena kutulutsidwa kwa madzi; imathanso kupangidwa kukhala madzi ofalikira kuti iphimbe, kuviika kapena kupanga ulusi. Polytetrafluoroethylene imagwiritsidwa ntchito kwambiri m'mafakitale monga mphamvu ya nyukiliya, chitetezo cha dziko, ndege, zamagetsi, zamagetsi, mankhwala, makina, zida, mita, zomangamanga, nsalu, chithandizo cha pamwamba pa chitsulo, mankhwala, chithandizo chamankhwala, nsalu, chakudya, zitsulo ndi kusungunula, ndi zina zotero. , Zipangizo zosagwira dzimbiri, zipangizo zotetezera kutentha, zokutira zotsutsana ndi ndodo, zokutira zotsutsana ndi ndodo, ndi zina zotero, zomwe zimapangitsa kuti ikhale chinthu chosasinthika. PTFE ili ndi makhalidwe abwino kwambiri, kukana kutentha kwambiri, kukana dzimbiri, kusamamatira, kudzipaka mafuta, makhalidwe abwino kwambiri a dielectric, ndi coefficient yochepa kwambiri ya kukangana. Imagwiritsidwa ntchito ngati pulasitiki yaukadaulo, imatha kupangidwa kukhala machubu a PTFE, ndodo, malamba, mbale, mafilimu, ndi zina zotero. Nthawi zambiri imagwiritsidwa ntchito m'mapaipi osagwira dzimbiri, zotengera, mapampu, ma valve, radar, zida zolumikizirana zamafupipafupi, ndi zida zama wailesi zomwe zimafunikira magwiridwe antchito apamwamba. Powonjezera chodzaza chilichonse chomwe chingapirire kutentha kwa PTFE, mawonekedwe ake amakanika amatha kusinthidwa kwambiri. Nthawi yomweyo, zinthu zina zabwino kwambiri za PTFE zimasungidwa. Mitundu yodzazidwa ndi monga ulusi wagalasi, chitsulo, oksidi yachitsulo, graphite, molybdenum disulfide, ulusi wa kaboni, polyimide, EKONOL... ndi zina zotero. Kukana kuwonongeka ndi malire a PV zitha kuwonjezeredwa ndi nthawi 1000.

Thepayipi ya PTFEImapangidwa ndi utomoni wa polytetrafluoroethylene woyimitsidwa ndi polymerized polymerized kudzera mu plunger extrusion processing. Pakati pa pulasitiki yodziwika bwino, PTFE ili ndi mankhwala abwino kwambiri okana komanso dielectric. PTFE yolukidwa ndi PTFE ndi chinthu chabwino chotseka. Imalukidwa kuchokera ku tepi yokulirapo ya PTFE. Ili ndi makhalidwe abwino kwambiri monga friction coefficient yochepa, kukana kukalamba, kukana dzimbiri kwa mankhwala, kutseka bwino, kusagwiritsa ntchito hydrolysis, komanso kusalimba. Imagwiritsidwa ntchito poyika ma gasket seals ndi zinthu zopaka mafuta zomwe zimagwira ntchito m'njira zosiyanasiyana, komanso zoteteza magetsi zomwe zimagwiritsidwa ntchito pansi pa ma frequency osiyanasiyana. Capacitor dielectric, kutchinjiriza chingwe, kutchinjiriza zida zamagetsi, ndi zina zotero. Filimu ya PTFE ndi yoyenera kutchinjiriza ma capacitor dielectrics, zingwe zapadera, kutchinjiriza waya, kutchinjiriza magetsi ndi zida ndi ma gaskets otseka. Ingagwiritsidwenso ntchito ngati tepi yosamatira, tepi yotseka, ndi kuchotsa

Zipangizo zambiri

Ndodo zosiyanasiyana, machubu, mafilimu a pepala, malamba, zingwe, zopakira, ma gasket, ndi graphite, molybdenum disulfide, aluminiyamu oxide, ulusi wagalasi, ndi ulusi wa kaboni zimagwiritsidwa ntchito ngati zodzaza kuti ziwongolere mawonekedwe a PTFE yoyera.
