Kev piav qhia ntawm PTFE=Teflon=PTFE=F4

Polytetrafluoroethylene [PTFE, F4] yog ib qho zoo tshaj plaws corrosion-resistant cov ntaub ntawv nyob rau hauv lub ntiaj teb no niaj hnub no, li no tau txais lub npe menyuam yaus ntawm "yas huab tais". Nws tuaj yeem siv tau ntev hauv txhua hom tshuaj nruab nrab, thiab nws qhov tshwm sim tau daws ntau yam teeb meem hauv Suav teb cov tshuaj, roj av, tshuaj thiab lwm yam. PTFE seals, gaskets, thiab gaskets PTFE seals, gaskets, thiab sealing washers yog tsim los ntawm kev siv ncua kev kawm ntawv polymerized PTFE resin molding. Piv nrog rau lwm cov yas, polytetrafluoroethylene muaj cov tshuaj tiv thaiv corrosion zoo heev thiab kub tsis kam, thiab nws tau dav siv los ua cov khoom sib khi thiab ntim khoom.

Cov mis molecular ntawm polytetrafluoroethylene yog ib tug polymer ntawm tetrafluoroethylene. Cov lus Askiv luv yog PTFE. Cov khoom npe yog "Teflon". Lub hauv paus qauv ntawm polytetrafluoroethylene yog CF2- CF2- CF2- CF2- CF2- CF2- CF2- CF{ {7}} CF2- CF2- Polytetrafluoroethylene yog dav siv nyob rau hauv ntau yam lag luam uas yuav tsum tau tiv taus acid, alkali, thiab organic solvents. Nws tsis yog tshuaj lom rau tib neeg, tab sis yog ib qho ntawm cov khoom siv raw siv hauv cov txheej txheem tsim khoom, perfluorooctanoic acid ammonium (PFOA), suav tias muaj cov teebmeem carcinogenic.

Polytetrafluoroethylene (Teflon los yog PTFE), nrog Suav lag luam npe xws li "Teflon", "Teflon", "Teflon", "Teflon", thiab lwm yam. Nws yog ib tug siab molecular compound polymerized los ntawm tetrafluoroethylene, uas muaj zoo heev tshuaj stability, corrosion kuj, sealing, siab lubrication, tsis viscosity, hluav taws xob rwb thaiv tsev thiab zoo anti-aging endurance. Muaj peev xwm ua haujlwm tau ntev ntev ntawm qhov kub thiab txias xws li +250 degree rau -180 degree, tiv taus txhua yam tshuaj tshwj tsis yog cov hlau molten sodium thiab kua fluorine, thiab tseem tsis hloov pauv thaum boiled hauv aqua regia.

Siv los ua engineering yas, nws tuaj yeem ua rau hauv cov kav dej polytetrafluoroethylene, rods, siv, daim hlau, zaj duab xis, thiab lwm yam. Feem ntau siv rau hauv cov kav dej tiv thaiv corrosion, ntim, twj, li qub nrog kev ua haujlwm siab, nrog rau radar, kev sib txuas lus siab. cov khoom siv, cov khoom siv hluav taws xob tsis muaj zog, thiab lwm yam. Cov kua disperse tuaj yeem siv los ua cov tshuaj tiv thaiv impregnation rau ntau yam ntaub ntawv thiab tiv thaiv corrosion txheej ntawm cov hlau, iav, thiab cov tais diav. Ntau yam PTFE rings, PTFE gaskets, PTFE packing, thiab lwm yam yog dav siv rau sealing ntau yam anti-corrosion pipeline flanges. Tsis tas li ntawd, nws kuj tuaj yeem siv rau kev kos duab, PTFE fiber - fluorine fiber (lub npe txawv teb chaws yog Teflon).

Tam sim no, ntau yam khoom siv polytetrafluoroethylene tau ua lub luag haujlwm tseem ceeb hauv kev lag luam hauv tebchaws, suav nrog tshuaj lom neeg, tshuab, hluav taws xob, hluav taws xob, tub rog, aerospace, kev tiv thaiv ib puag ncig, thiab kev lag luam choj.

Polytetrafluoroethylene (PTFE) yog siv rau hauv kev lag luam xws li tshuaj lom neeg, petrochemical, roj refining, chlor alkali, acid ua, phosphate chiv, tshuaj, tshuaj tua kab, tshuaj fiber ntau, dyeing, coking, thee gas, organic synthesis, non-ferrous smelting, steel, atomic zog, thiab high-purity khoom ntau lawm (xws li ion membrane electrolysis), viscous khoom thauj thiab kev khiav hauj lwm, thiab zaub mov, dej haus, thiab lwm yam kev ua thiab ntau lawm departments nrog heev nruj kev cai huv si.
