Uiga o le pepa PTFE

PTFE laupapa (faʻapitoa foi o le PTFE laupapa, Teflon laupapa, Teflon laupapa) ua vaevaeina i ni ituaiga se lua: faʻailoga ma liliu.O ana oloa o loʻo faʻaaogaina lautele ma e sili atu le maualuga o mea faʻapitoa: maualuga ma maualalo le vevela (-192 ° C-260 ° C), faʻafefeteina (malosi malosi, malosi alkali, aqua regia, ma isi), tau tetee, faʻagata maualuga, lubrication maualuga, non-adhesion, Non-o'ona ma isi uiga sili ona lelei.Polytetrafluoroethylene (Faapuupuuga faa-Peretania o Teflon poʻo [PTFE, F4]), e taʻua / masani ona taʻua o le "Plastic King", igoa faʻatau Saina "Teflon", "Teflon" (teflon), "Teflon" , "Teflon", "Teflon" ma faapena atu ai lava.
O se vaega mole maualuga polymerized e tetrafluoroethylene, ma lona fausaga faigofie -[-CF2-CF2-]n-, lea e lelei le mautu kemisi ma corrosion tetee (polytetrafluoroethylene ua taʻua o le PTFE po o le F4, o se tasi o le sili ona pala. -mea fa'asa'o i le lalolagi i aso nei, "Plastic King" e masani ona ta'ua o le polytetrafluoroethylene, o se palasitika e sili ona lelei le fa'afefeteina. fa'atasi ai ma lea mea, o lea ua ta'ua ai le tupu palasitika E tetee atu i isi vaila'au uma se'i vagana ai le sodium u'amea u'amea ma le vai fluorine Le pipii, insulation eletise ma lelei le matua tete'e, lelei le vevela tetee (e mafai ona galue mo se taimi umi i le vevela o + 250 ° C i le -180 ° C) O le PTFE lava ia e le oona i tagata, ae o loʻo faʻaaogaina i le gaosiga o le gaosiga O se tasi o mea mataʻutia o le ammonium perfluorooctanoate (PFOA) ua manatu e mafai ona avea o se carcinogen.
Tempera -20～250°C (-4～+482°F), fa’ataga fa’afuase’i le mālūlū ma fa’avevela fa’afuase’i, po’o le fa’agaoioia o le malulu ma le vevela.
Omiga -0.1～6.4Mpa (Ato'a gaogao i le 64kgf/cm2) (Ato'a gaogao i le 64kgf/cm2)
O lona gaosiga ua foia ai le tele o faʻafitauli i le matata o vailaʻau vailaʻau, suauu ma vailaʻau i lo tatou atunuu.fa'amaufa'ailoga PTFE, gaskets, gaskets, fa'amaufa'ailoga PTFE, ma gaskets o lo'o faia i le fa'amalologa polymerized PTFE resin molding.Pe a faatusatusa i isi palasitika, o le PTFE o loʻo i ai uiga o le faʻamaʻiina o vailaʻau, ma ua faʻaaogaina lautele e avea ma mea faʻamaufaʻailoga ma mea faʻatumu.
O ana oloa fa'ato'a fa'amama atoatoa i le tusa ma le 500 tikeri Celsius e aofia ai le tetrafluoroethylene, hexafluoropropylene ma le octafluorocyclobutane, lea o le a fa'apalapala ai kasa o lo'o i ai le fluorine i le vevela maualuga.
