Yuav ntsuas qhov corposion tsis kam ntawm teflon txheej txheej siv cov qauv electrochemical?

Muaj ob peb txoj hauv kev los ntsuas qhov corrosion tsis kam ntawm Teflon txheej txheej siv cov qauv electrochemical:
Kev Ntsuas Polarization
Txoj cai: los ntawm kev ntsuas qhov ceev tam sim no ntawm cov khoom sib txawv ntawm cov hlau sib txawv yog muaj feem cuam tshuam nrog cov txheej txheem corroscation yog muaj feem cuam tshuam txog cov txheej txheem corroscation xws li cov txheej txheem ntawm cov hlau sib txawv xws li cov pa roj carbonation
Kuaj cov kauj ruam
Kev npaj: tus qauv coated nrog Teflon yog siv los ua cov ua haujlwm electrode (}} Cov Platinum Electrode (} lwm yam {., thiab tom qab ntawd txuas nws mus rau qhov kev sim ntsuas ntsuas {}}
Cov txheej txheem kuaj: Tso peb-electrode system nyob rau hauv ib qho kev daws teeb meem uas sim ua haujlwm rau ib puag ncig ua haujlwm, thiab sau cov nqi sib txawv ntawm cov peev txheej tam sim no {}}
Kev tsom xam cov ntaub ntawv: Raws li kev nkhaus polariat, ecorr) thiab corrosion tam sim no (iCorr) thiab ntau dua cov khoom lag luam corrosion, qhov zoo dua cov corrosion tsis kam ntawm cov txheej; Qhov me me rau kev xeb tam sim no ceev, tus muaj zog tiv thaiv cov nyhuv ntawm cov txheej txheem ntawm cov tshuaj tiv thaiv corrosion, cov kauj ruam tswj ntawm Tafel Slope .
Electrochemical impedance spectroscopy (EIS) kuaj
Lub hauv paus ntsiab lus: nyob rau hauv ib tug me mplitude pititional discedance thiab tau txais cov txheej corrosting ntawm cov imporance, thiab tau txais cov txheej txheem tiv thaiv hluav taws xob, kev puas tsuaj, thiab txheej kev puas tsuaj.
Kuaj cov kauj ruam
Kev npaj: zoo ib yam li Polariaation nkhaus, npaj cov haujlwm electrode, thiab kev siv electrode, thiab huv thiab txuas cov khoom ua haujlwm electrode {}}
Cov txheej txheem kuaj: Tso lub tshuab hluav taws xob hauv cov teeb liab electrolyoid thiab ntau dua yog los ntawm cov ntaub ntawv sib txawv kom tau impedance spectrum cov ntaub ntawv .
Cov ntaub ntawv tsom xam: impedance feem ntau yog nthuav tawm nyob rau hauv daim ntawv ntawm cov txheej txheem circuitance (RC), cov txheej txheem hluav taws xob tsis kam (RC) lwm yam {. qhov loj dua cov txheej tsis kam, qhov zoo dua qhov teeb meem ntawm cov txheej thiab lub zog ua rau corrosion; tus me dua cov txheej txheej capacitance, qhov siab dua ntawm cov txheej txheej ntawm txheej .
Muaj Peev Xwm Zaug Hluav Taws Xob (PDR)
Lub hauv paus ntsiab lus: raws li cov suab nrov Electrochemical thiab qhov tsis xws luag ntawm cov kev hloov pauv hloov ntawm cov txheej txheem ntawm cov txheej txheem corrosion .
Kuaj cov kauj ruam
Kev npaj: siv ob qho kev siv ua haujlwm zoo ib yam li Teflon, ib qho uas siv hluav taws xob thiab txuas ntxiv}} {.
Cov txheej txheem kuaj: Tso lub tshuab hluav taws xob hauv cov hluav taws xob hauv tshuab hluav taws xob, thiab cov khoom siv ua haujlwm tau zoo lossis tsis muaj kev hloov pauv thiab hloov pauv hauv lub peev xwm .
Cov ntaub ntawv tsom xam: kev ncaj ncees thiab corrosion tsis zoo ntawm cov ntaub ntawv sib txawv, xws li kev ntsuas cov peev txheej ntawm cov khoom siv hluav taws xob tsis zoo lossis muaj cov kev sib cav sib ceg lossis cov hluav taws xob muaj tshwm sim.
Cov txheej txheem xeem electrochemical tuaj yeem muab cov ntaub ntawv nplua nuj txog kev ntsuas tefle, tab sis hauv kev sim ua kom paub tseeb, kev sim ua ke, kev sim ua ke, cov tshuaj tiv thaiv kev ua haujlwm ntawm cov txheej corrosion txhob txwm ua kom muaj kev nkag siab zoo dua .
