PTFE board (inozivikanwawo se PTFE board, Teflon board, Teflon board) yakakamurwa kuita mhando mbiri: kuumba uye kutendeuka.Zvigadzirwa zvaro zvinoshandiswa zvakanyanya uye zvine hunyanzvi hwepamusoro-soro hunhu: yakakwirira uye yakaderera tembiricha kuramba (-192 ° C-260 ° C), corrosion resistance (yakasimba asidhi, yakasimba alkali, aqua regia, nezvimwewo), kuramba kwemamiriro ekunze, kuvharira kwakanyanya, high lubrication, isina-adhesion, Non-chepfu uye mamwe akanakisa maitiro.Polytetrafluoroethylene (chirungu chipfupiso cheTeflon kana [PTFE, F4]), inozivikanwa se/inowanzozivikanwa se “Plastic King”, Chinese trade name “Teflon”, “Teflon” (teflon), “Teflon” , “Teflon”, “Teflon” zvichingoenda zvakadaro.
Iyo yakakwira molecular compound polymerized ne tetrafluoroethylene, uye chimiro chayo chakareruka ndeye [-CF2-CF2-]n-, ine yakanakisa kugadzikana kwekemikari uye kusagadzikana kwekuora (polytetrafluoroethylene inodaidzwa kunzi PTFE kana F4, ndeimwe yezvakanyanya kukora. -resistant zvinhu munyika nhasi, "Plastic King" inowanzozivikanwa sepolytetrafluoroethylene, ipurasitiki ine yakanyanya kunaka kusagadzikana.Haisi kukanganiswa neanozivikanwa acids, alkalis, munyu, oxidants Corrosion, kunyangwe aqua regia haina chekuita. nayo, saka inodaidzwa kunzi mambo epurasitiki.Inoshingirira kune mamwe makemikari ese kunze kwesimbi yakanyungudutswa yesodium uye liquid fluorine.Isina kunamira, magetsi ekudzivirira uye kuramba kuchembera kwakanaka, kushomeka kwakanyanya (inogona kushanda kwenguva yakareba patembiricha ye +250°C kusvika -180°C) PTFE pachayo haina chepfu kuvanhu, asi inoshandiswa pakugadzira Imwe yezvigadzirwa zveperfluorooctanoate ammonium (PFOA) inonzi inogona kukonzera kenza.
Tembiricha -20～250°C (-4～+482°F), zvichibvumira kutonhora nekukasika nekudziya, kana kumwe kushanda kwekutonhora nekupisa.
Pressure -0.1～6.4Mpa (Full vacuum to 64kgf/cm2) (Full vacuum to 64kgf/cm2)
Kugadzirwa kwayo kwakagadzirisa matambudziko mazhinji muminda yemakemikari indasitiri, petroleum nemishonga munyika yedu.PTFE zvisimbiso, gaskets, gaskets, PTFE zvisimbiso, uye gaskets akagadzirwa akamiswa polymerized PTFE resin molding.Kuenzaniswa nemamwe mapurasitiki, PTFE ine hunhu hwemakemikari corrosion resistance, uye yakashandiswa zvakanyanya sechinhu chekuisa chisimbiso uye zvinhu zvekuzadza.
Zvigadzirwa zvayo zvekuora zvinopisa zvinopisa zvinenge 500 madhigirii celsius zvinosanganisira tetrafluoroethylene, hexafluoropropylene uye octafluorocyclobutane, inozoora magasi ane fluorine ane hutsinye pakupisa kwakanyanya.
