Zonke izinhlobo zemikhiqizo ye-PTFE zidlale indima ebalulekile emikhakheni yezomnotho kazwelonke njengemboni yamakhemikhali, imishini, izinto zikagesi, izinto zikagesi, imboni yezempi, i-aerospace, ukuvikelwa kwemvelo namabhuloho.
Ibhodi le-Tetrafluoroethylene lilungele izinga lokushisa -180℃~+250℃.Isetshenziswa kakhulu njengezinto zokufakelwa kukagesi kanye namalayini okuxhumana nemidiya ebolayo, izilayidi ezisekelayo, izigxivizo zikaloliwe kanye nezinto zokugcoba.Isetshenziswa embonini yokukhanya yifenisha yekhabhinethi ecebile., Isetshenziswa kakhulu kumakhemikhali, ekhemisi, ezitsheni zemboni kadayi, amathangi okugcina, amaketela ombhoshongo wokusabela, izinto zokuvikela ukugqwala kwamapayipi amakhulu;ezezindiza, ezempi kanye nezinye izimboni ezinzima;imishini, ukwakhiwa, izilayidi zebhuloho lethrafikhi, ojantshi abaqondisayo;ukuphrinta nokudaya, imboni ekhanyayo, izindwangu zokulwa nokunamathela izinto zemboni, njll.
Izinzuzo zezinto ezibonakalayo
Ukumelana nokushisa okuphezulu - izinga lokushisa lokusebenza lingafinyelela ku-250 ° C.
Ukumelana nokushisa okuphansi - kunokuqina okuhle kwemishini;ngisho noma izinga lokushisa lehla liye ku-196°C, lingakwazi ukugcina ubude obungu-5%.
Ukumelana nokugqwala - ukungena kumakhemikhali amaningi nezincibilikisi, amelana nama-asidi aqinile nama-alkali, amanzi kanye nezincibilikisi ezihlukahlukene eziphilayo.
Ukumelana nesimo sezulu - kunempilo engcono kakhulu yokuguga phakathi kwamapulasitiki.
I-lubrication ephezulu - i-coefficient ephansi yokungqubuzana phakathi kwezinto eziqinile.
Ukunganamatheli - kungukungezwani kwendawo encane kunazo zonke phakathi kwezinto eziqinile, akunamatheli kunoma iyiphi into, futhi izakhiwo zayo zemishini zine-coefficient encane kakhulu yokungqubuzana, okuyi-1/5 kuphela ye-polyethylene, okuyisici esibalulekile se-perfluorocarbon. izindawo ezingaphezulu.Futhi ngenxa yamandla aphansi kakhulu e-intermolecular of fluorine-carbon chain, i-PTFE ayinamathele.
Non-toxic - ayinazo i-physiologically inert futhi ayinakho ukusabela okubi lapho ifakwe emzimbeni njengomkhumbi wegazi wokwenziwa kanye nesitho isikhathi eside.
Izakhiwo zikagesi I-PTFE inokulahleka kwe-dielectric ephansi kanye ne-dielectric ebangeni elibanzi lefrikhwensi, kanye ne-voltage yokuphuka okuphezulu, ukumelana nevolumu kanye nokumelana ne-arc.
Ukumelana nemisebe Ukumelana nemisebe ye-polytetrafluoroethylene kubi (104 rads), futhi konakaliswa yimisebe enamandla amakhulu, futhi izakhiwo zikagesi nezomshini we-polymer ziyancipha kakhulu.I-PTFE yohlelo lokusebenza ingacutshungulwa ngokucindezelwa noma i-extrusion;ingenziwa futhi ibe yi-aqueous dispersion yokugqoka, ukumilisa noma ukwenza imicu.I-PTFE isetshenziswa kabanzi njengezinto ezimelana nezinga lokushisa eliphezulu neziphansi, ukumelana nokugqwala, izinto zokuvikela, okokuvikela induku, njll. emandleni e-athomu, emkhathini, kugesi, ngogesi, amakhemikhali, imishini, izinsimbi, amamitha, ukwakhiwa, izindwangu, ukudla nokunye. izimboni.
Ukumelana nokuguga kwe-atmospheric: ukumelana nemisebe kanye nokungena okuncane: ukuchayeka isikhathi eside emkhathini, indawo engaphezulu nokusebenza kuhlala kungashintshile.
Ukungashi: Inkomba ye-oxygen ekhawulelayo ingaphansi kwama-90.
Ukumelana ne-Acid ne-alkali: ayincibiliki ku-asidi eqinile, i-alkali eqinile kanye ne-organic solvent.
Ukumelana ne-oxidation: Kungamelana nokugqwala kwama-oxidants aqinile.
I-Acidity kanye ne-alkalinity: hlangothi.
Izici zemishini ze-PTFE zithambile.Inamandla angaphezulu aphansi kakhulu.
I-Polytetrafluoroethylene (F4, PTFE) inochungechunge lwemisebenzi emihle kakhulu: ukumelana nokushisa okuphezulu - izinga lokushisa lokusetshenziswa isikhathi eside 200 ~ 260 degrees, ukumelana nokushisa okuphansi - kusathambile kuma-degrees -100;ukumelana nokugqwala - ukumelana ne-aqua regia nazo zonke izinyibilikisi eziphilayo;Ukumelana nesimo sezulu-impilo engcono kakhulu yokuguga phakathi kwamapulasitiki;i-lubricity ephezulu—i-coefficient encane yokungqubuzana (0.04) phakathi kwamapulasitiki;i-non-stick-ingcindezi encane kunazo zonke phakathi kwezinto eziqinile ngaphandle kokunamathela kunoma iyiphi into;non-toxic-inert physiologically;Izakhiwo zikagesi ezinhle kakhulu, iyinto efanelekile yokuvikela i-Class C.
