PTFE ke eng?
Polytetrafluoroethylene (PTFE) ke mofuta oa polymer e entsoeng ka tetrafluoroethylene joalo ka monoma. E na le mocheso o babatsehang le ho hanyetsa serame 'me e ka sebelisoa nako e telele ho tloha ho 180 ~ 260 º C. Boitsebiso bona bo na le litšobotsi tsa ho hanyetsa acid, ho hanyetsa alkali le ho hanyetsa lihlaseli tse fapa-fapaneng tsa lintho tse phelang, 'me hoo e ka bang ha ho qhibilihe ka har'a metsoako eohle. Ka nako e ts'oanang, polytetrafluoroethylene e na le litšoaneleho tsa ho hanyetsa mocheso o phahameng, 'me coefficient ea eona ea likhohlano e tlase haholo, kahoo e ka sebelisoa bakeng sa lubrication, hape e fetoha seaparo se setle bakeng sa ho hloekisa habonolo ha karolo e ka hare ea liphaephe tsa metsi. PTFE e bua ka tlatsetso ea PTFE barbotage lesela ka hare ho tloaelehileng EPDM rabara kopanetsweng, eo haholo-holo e tšoeu.
Karolo ea PTFE
PTFE e ka sireletsa ka katleho manonyeletso a rabara ho tloha ho acid e matla, alkali e matla kapa oli e phahameng ea mocheso le ho bola ha mecha ea litaba.
Morero
- E sebelisoa indastering ea motlakase le joalo ka lera la ho kenya letsoho, thepa e hanyetsanang le kutu le e sa senyeheng bakeng sa matla le mehala ea lipontšo sebakeng sa sefofane, sefofane, lisebelisoa tsa elektroniki, lisebelisoa, likhomphutha le liindasteri tse ling. E ka sebelisoa ho etsa lifilimi, maqephe a li-tube, lithupa, li-bearings, li-gaskets, li-valve, liphaephe tsa lik'hemik'hale, lisebelisoa tsa liphaephe, lisebelisoa tsa lisebelisoa, joalo-joalo.
- E sebelisoa masimong a lisebelisoa tsa motlakase, indasteri ea lik'hemik'hale, lifofane, mechini le masimong a mang ho nka sebaka sa khalase ea quartz bakeng sa tlhahlobo ea lik'hemik'hale tse hloekileng le ho boloka li-acid tse fapaneng, alkalis le li-solvents tsa manyolo masimong a matla a atomic, meriana, semiconductor. le liindasteri tse ling. E ka etsoa hore e be likarolo tsa motlakase tse kenang ka bongata, terata e phahameng ea maqhubu le likhetla tsa thapo, lisebelisoa tsa lik'hemik'hale tse hananang le kutu, lipeipi tsa oli tse hanyetsanang le mocheso o phahameng, litho tsa maiketsetso, joalo-joalo. mafura, joalo-joalo.
- PTFE e hanyetsana le mocheso o phahameng le ho bola, e na le motlakase o motle haholo, e thibela ho tsofala, ho monya metsi a tlase, le ts'ebetso e ntle haholo ea ho itlotsa. Ke universal lubricating powder e loketseng mecha ea litaba e fapaneng, 'me e ka koaheloa ka potlako ho etsa filimi e omileng, e ka sebelisoang e le sebaka sa graphite, molybdenum le lisebelisoa tse ling tsa tlhaho. Ke sesebelisoa sa tokollo se loketseng li-polymer tsa thermoplastic le thermosetting, tse nang le bokhoni bo botle ba ho jara. E sebelisoa haholo indastering ea elastomer le rabara le ho thibela ho bola.
- Joalo ka setlamo sa epoxy resin, se ka ntlafatsa ho hanyetsa mocheso, ho hanyetsa mocheso le ho hanyetsa kutu ea sekhomaretsi sa epoxy.
- E sebelisoa haholo-holo e le binder le filler ea phofo.
Melemo ea PTFE
- Ho hanyetsa mocheso o phahameng - mocheso o sebetsang ho fihlela ho 250 ℃
- Ho hanyetsa mocheso o tlase - boima bo botle ba mechine; Leha mocheso o theohela ho -196 ℃, bolelele ba 5% bo ka bolokoa.
- Corrosion resistance - bakeng sa lik'hemik'hale tse ngata le li-solvents, ha e kenelle ebile e hanyetsana le li-acids tse matla le alkalis, metsi le mefuta e sa tšoaneng ea metsoako ea tlhaho.
- Ho hanyetsa boemo ba leholimo - ho na le bophelo bo botle ba botsofali ba polasetiki.
- Lubrication e phahameng ke coefficient e tlase ea likhohlano har'a lisebelisoa tse tiileng.
- Ho se khomarele - ke tsitsipano e fokolang ea holim'a thepa e tiileng 'me ha e khomarele ntho leha e le efe.
- Ha e na chefo - E na le inertia ea 'mele,' me ha e na liphetoho tse mpe ka mor'a ho kenngoa ha nako e telele e le methapo ea mali le litho tsa maiketsetso.
- Motlakase oa motlakase - o ka mamella matla a phahameng a 1500 V.
