Dab tsi yog cathodic tiv thaiv technology?

Cathodic tiv thaiv tshuab yog ib qho cuab yeej siv tam sim no hauv kev lag luam. Nws tsuas yog tiv thaiv cov qauv hlau los ntawm corrosion los ntawm kev siv lub cathodic tam sim no rau saum npoo. Cathodic tiv thaiv kev siv tshuab tsis tuaj yeem txuas ntxiv lub neej ntawm cov cuab yeej siv thiab txo cov khoom siv tu lub voj voog, tab sis kuj txo cov nqi tu thiab xyuas kom ruaj khov thiab kev ntseeg siab ntawm cov cuab yeej siv. Hauv kev tsim khoom lag luam, cathodic tiv thaiv thev naus laus zis tau siv dav, thiab cov tshiab tau nthuav tawm tas li, thiab qib kev txhim kho niaj hnub.

Txoj kev loj hlob ntawm cathodic tiv thaiv technology muaj keeb kwm ntev. Raws li thaum ntxov xyoo pua 19th, qee cov kws tshawb fawb tau npaj lub tswv yim ntawm kev siv hluav taws xob tam sim no rau cov hlau nto kom txo tau qhov tshwm sim ntawm corrosion. Thaum pib ntawm lub xyoo pua 20th, cathodic tiv thaiv tshuab tau nrov nrov thiab txhawb nqa, thiab tau siv dav hauv kev ua tub rog thiab kev lag luam. Tam sim no, nws tau siv dav hauv ntau lub lag luam xws li roj thiab roj kav dej, kev kho dej, txuas hniav, dav hlau, nkoj, thiab lwm yam, thiab cov cuab yeej siv niaj hnub hloov kho thiab tsim kho tshiab.

Cov txheej txheem kev lag luam cathodic tiv thaiv kev lag luam kuj tseem txhim kho tas li. Raws li cov kev xav tau ntawm ntau yam kev lag luam txuas ntxiv hloov thiab ntu, cathodic tiv thaiv thev naus laus zis tau hloov kho thiab txhim kho tas li. Piv txwv li, hauv kev tiv thaiv cathodic ntawm cov kav dej hauv nroog, passive cathodic tiv thaiv thev naus laus zis tau txais yuav nyob rau xyoo tas los no. Cov tshuab no tuaj yeem tsis tsuas yog txo cov dej paug, tab sis kuj txo cov nqi kho. Hauv kev tiv thaiv cathodic ntawm faus roj pipelines, tshiab roj corrosion inhibitors tau tshwm sim nyob rau hauv xyoo tas los. Los ntawm gasifying rau sab hauv ntawm lub raj xa dej, lawv ua tiav kev tiv thaiv zoo dua ntawm cov kav dej txhua qhov kev tiv thaiv corrosion.

Nrog rau kev txhim kho txuas ntxiv ntawm tib neeg, cov kev cai rau kev tiv thaiv ib puag ncig tau nce siab dua thiab siab dua, thiab cathodic tiv thaiv tshuab muab cov kev daws teeb meem txhim khu kev qha rau qhov no. Hauv cov txheej txheem kev tiv thaiv cathodic, cov anode feem ntau yog ua los ntawm cov hlau lead-antimony alloy, uas tuaj yeem tsim cov tshuaj lom neeg xws li arsenic thiab txhuas thaum siv, ua rau muaj kuab paug rau ib puag ncig. Tam sim no, qee cov khoom siv anode tshiab xws li txhuas, zinc alloy, siab silicon cam khwb cia hlau, titanium anodes, thiab lwm yam tau siv dav. Tshwj xeeb, MMO titanium anodes zam ib puag ncig muaj kuab paug thiab tseem txhim kho cov cuab yeej kev ntseeg siab thiab ruaj khov.

Daim ntawv thov kev cia siab ntawm cathodic tiv thaiv technology yog dav heev. Raws li qhov kev thov rau nws nyob rau hauv ntau yam kev lag luam nce, nws cov txheej txheem yuav txuas ntxiv txhim kho, ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv ib puag ncig rau tib neeg thiab ua kom muaj kev ntseeg siab ntawm cov khoom siv. Yav tom ntej, peb tuaj yeem cia siab tias cathodic tiv thaiv thev naus laus zis txuas ntxiv ua lub luag haujlwm hauv kev lag luam ib txwm muaj thaum tsim cov ntawv thov tshiab hauv kev lag luam tawm tshiab. Txawm hais tias theem ntawm kev siv thev naus laus zis txuas ntxiv txhim kho, peb tseem yuav tsum tau hais ntxiv txog cov teeb meem kev nyab xeeb hauv kev siv thev naus laus zis thiab pab txhawb rau noob neej yav tom ntej.
