ANODE ICCP RAU LUB

Edit: Shaanxi Elade tshiab khoom Technology Co., Ltd    Date: Dec 03, 2015

ANODE rau ICCP SYSTEMS
Taw qhia hais
ICCP tshuab ua tus zoo qauv rau corrosion tswj tau tau lug tso cai los ntawm tus neeg.
Txoj cai hais raws li cov kev tshawb xav ntawm electrochemical. Cov khoom siv los tiv thaiv ua ntej ntawm corrosion los lem ntawm ib cathode lwm tam sim no, tej zaum deg ntawm cov khoom tiv thaiv kom tsis txhob. Yog li tus corrosion npaum li cas cov hlau lov. ICCP tshuab muaj tau lug hos hauv pob zeb ua kev reinforced, ships, txuas hniav, tso tsheb hlau luam, siv tshuaj, pipeline thiab lwm yam. Ntu anodes yog ib lub Cheebtsam tub ntxhais ntawm lub nruab ICCP, nws ntaus nqe hnyav rau ntu anodes yog xaiv.


Nyob rau ntu anode zoo tagnrho rau ICCP


Superior hluav taws xob conductivity, ua thaum muaj chaw ceev, polarizability uas tsis muaj.
Thaum cov ntaub ntawv nyob rau hauv cheeb tsam, Anode yuav tsum muaj zoo txhob (zoo li qub), electrochemical (dynamic) stability, noj tsawg, ntev tau leej twg lub neej.
Anode yuav tsum muaj tej yam kev kawm mechanics.
Nws yog ib qho ntaub ntawv, coj, nruab thiab siv yooj yim.
Tsis tshua muaj nqi ntawm txij nkawm.
Anti-puas, Anti-yaig.
Tsis muaj chaw muaj kuab paug rau lub sij hawm zov me nyuam.


Xaiv ntawm ntu anode rau ICCP
Thiaj li xaiv ntu anodes zoo, peb yuav tsum paub qhov teeb meem ntawm thermodynamics thiab cov anode dynamic nrog lub electrochemical haum nyob rau hauv lub chaw kawm tshwj xeeb.

Xaiv ntawm ntu anode rau ICCP
Puab
Tam sim no siv: tsis muaj tej yam yuav siv fais fab rau lub anode, qhov chaw ceev ntawm anode no ua rau yus, qhov chaw ceev yuav feem xyuam rau txoj lub overpotential ntawm anode, ces ua rau cov khoom muag anode.
Qhov concentration hloov rau conductive ionic ntawm kev ua hauj lwm tawm, nws xws li cov reactant thiab resultant. Piv txwv li, cov tshuaj tiv thaiv ntawm anode yog evolution tshuaj, nws nyiaj loj ntawm cov tshuaj ion nyob seawater, thiab tej zaum rau ntawm tshuaj evolution no tsawg dua cov pa evolution, yog hais tias nws yog ib qho uas me me thiab ua zoo ib puas ncig seawater.the anode yuav tshuaj evolution ntawd firstly tshuaj thiab cov pa evolution together.it tshwm sim ntawm cov tshuaj ionic cann't mov lawm.

Nws yuav pom ntawm lub teeb, noj nqos tau cov pa Evolution rau cov electrode ib yam yog dua obviously dua tshuaj Evolution. Tiam sis tus MMO Electrode tus uas tsis muaj noj rau cov evolution tshuaj thiab cov pa evolution, thiab MMO Anode nrog rau lwm yam zoo li zoo conductivity, loj txaus. Yog li ntawd MMO Anode yog tus zoo xaiv lub nruab ICCP.
