Cov txiaj ntsig tseem ceeb thiab daim ntawv thov Scenarios ntawm ICCP Cathodic Kev Tiv Thaiv rau Loj -Tej Cheeb Tsam Hlau Corrosion Control

Corrosion loj - cheeb tsam steel qauv yeej ib txwm ua haujlwm tseem ceeb thiab kev sib tw hauv kev lag luam hnyav xws li cov kav dej hauv nroog, kev lag luam hauv hiav txwv, cov tank loj thiab cov khoom siv steel hlau. Sib txawv los ntawm kev tiv thaiv tsis zoo-corrosion txoj kev suav nrog kev derusting, pleev xim thiab txheej tiv thaiv, Impressed Current Cathodic Protection (ICCP) tau dhau los ua qhov kev daws teeb meem zoo rau ntev -lub sij hawm tiv thaiv-corrosion loj- cheeb tsam steel qauv los ntawm kev tsim txiaj ntawm nws cov kev ua haujlwm tiv thaiv-corrosion kev ua tau zoo. Nws ua tib zoo daws cov ntsiab lus mob ntawm ib txwm siv los tiv thaiv- cov txheej txheem corrosion, xws li kev ua haujlwm luv luv, kev saib xyuas tsis tu ncua thiab kev tiv thaiv tsis tiav ntawm cov ces kaum tuag.

Feem ntau ib txwm siv los tiv thaiv- txoj kev xeb tsuas yog muab kev tiv thaiv kev sib cais rau cov qauv hlau. Thaum cov txheej txheej puas lawm, laus los yog tawg, dej vapor, ntsev, kua qaub thiab alkali xov xwm yuav sai sai invade cov hlau substrate, ua rau lub zos corrosion, pitting corrosion thiab txawm perforation. Tshwj xeeb tshaj yog nyob rau hauv hnyav ua hauj lwm ib puag ncig xws li cov ntug dej hiav txwv siab ntsev tsuag, underground humidity thiab industrial acid- puag corrosion, cov nyhuv tiv thaiv yuav poob qis heev, yuav tsum tau ntau xyoo kev nqis peev ntawm manpower thiab cov khoom siv rau kev soj ntsuam thiab kho dua tshiab. Hauv qhov sib piv, ICCP cathodic tiv thaiv cov khoom siv txuas ntxiv cathodic tam sim no rau cov qauv hlau los ntawm kev siv hluav taws xob sab nraud, hloov cov hlau electrode muaj peev xwm, thiab hauv paus inhibits cov tshuaj tiv thaiv oxidative corrosion ntawm hlau kom ua tiav kev tiv thaiv corrosion.

Piv nrog rau kev sacrificial anode cathodic tiv thaiv, qhov loj tshaj qhov zoo ntawm ICCP system yog nws adaptability rau loj - cheeb tsam thiab ntev -span steel qauv scenarios. Kev txwv los ntawm cov ntaub ntawv khaws tseg, kev txi anodes tsuas yog siv tau rau cov khoom siv hlau me me thiab tawg ua ke nrog txwv kev tiv thaiv ntau thiab kev pabcuam luv luv. ICCP system tuaj yeem kho qhov tso zis tam sim no raws li thaj chaw steel qauv, nruab nrab ib puag ncig thiab qib corrosion, nrog rau kev tiv thaiv ntau yam ntxiv. Featuring ruaj khov thiab kev pab lub neej ntev, nws muaj peev xwm ua tau raws li lub sij hawm ntev - tiv thaiv - corrosion xav tau ntawm loj -scale tej yaam num xws li loj tank ua liaj ua teb, subsea pipelines, wharf steel piles thiab nroog underground thoob dej yug ntses galleries.

Kev tiv thaiv kev txwv ntawm tag nrho ICCP cathodic kev tiv thaiv yog nyob ntawm kev ua haujlwm ntawm cov khoom siv anode. Raws li lub hauv paus ntsiab lus ntawm cov zis tam sim no, lub anode yog lub luag hauj lwm rau tusyees xa hluav taws xob tam sim no mus rau saum npoo ntawm steel qauv. Nws cov conductivity, corrosion kuj thiab stability ncaj qha txiav txim qhov kev tiv thaiv uniformity thiab kev pab cuam lub neej ntawm tag nrho cov system. Qhov no yog qhov laj thawj tseem ceeb vim li cas cov graphite anodes thiab steel anodes tau maj mam dhau mus thiab MMO titanium anodes tau dhau los ua kev lag luam tseem ceeb hauv kev lag luam.nt xya. Siab -kev ua tau zoo anodes tau dhau los ua tus yuam sij rau lub sijhawm ntev - thiab kev ua haujlwm ruaj khov ntawm ICCP systems.
