Cov khoom siv ua haujlwm anticorrosive Lub luag haujlwm tseem ceeb yog tiv thaiv kev xeb, kom ua tiav lub hom phiaj ntawm kev siv khoom siv sijhawm ntev. Tab sis vim yog lawv tus kheej tsim cov khoom siv thiab kev siv cov khoom siv ib puag ncig, uas tseem tso cai rau cov khoom siv xeb tsis tuaj yeem zam kev pheej hmoo ntawm kev xeb, Electrochemical Ntaus yog li peb yuav tsum nkag siab qee qhov laj thawj rau xeb ntawm cov khoom siv xeb kom nkag siab zoo dua cov anti -corrosion cov khoom siv los tiv thaiv xeb.
Kev txhim kho cov khoom siv kho kom zoo, feem ntau, feem ntau yog vim hluav taws xob xeb ntawm cov hlau. Thiab qhov hluav taws xob hluav taws xob ntawm cov tshuaj electrolyte tau paub tias yog kev xeb electrochemical. Nyob rau hauv lub ntuj ib puag ncig thiab kev tsim cov hlau xeb tau tshwm sim, feem coob yog electrochemical xeb. Xws li cov hlau cam khwb cia, carbon hlau, txhua hom hlau, tsis tshua muaj hlau, tooj, txhuas, txhuas thiab nws cov alloys feem ntau siv hauv cov hlau, muaj ntau hom alkali, kua qaub, ntsev tov; huab cua, av; dej muaj hluav taws xob, Cov Khoom Siv Hluav Taws Xob Hauv qhov xeb yog electrochemical corrosion, thiab cov hlau intergranular corrosion, pitting corrosion, kev nyuaj siab corrosion tawg thiab lwm qhov chaw ntawm kev xeb yog daim ntawv tshwj xeeb ntawm electrochemical corrosion. Cov cuab yeej ua haujlwm anticorrosive yog rau electrochemical kev xeb thiab xeb.
Txij li thaum koj paub cov tshuaj lom neeg nrog xeb, tom qab ntawd yuav ua li cas nrog? Cov khoom siv tiv thaiv kev ua kom tsis txhob xeb? Cov hau kev hauv qab no tuaj yeem siv los txo cov xeb:
1, yuav yog cov khoom siv tiv thaiv kev ua kom tsis txhob xeb, cov tshuaj lom nyob hauv ib puag ncig kom tshem tawm lwm cov khoom sib xyaw ua kom tshem tawm, kom thiaj li tsis tsim cov tshuaj tiv thaiv acid. Piv txwv li: cov dej tshem tawm - txhawm rau tiv thaiv cov teeb meem hauv tsev, kev tshem tawm cov pa oxygen hauv dej - kev tiv thaiv ntawm cov dej nruab nrab los ntawm carbon hlau xeb.
2, ntxiv cov cuab yeej ua kom zoo, ntxiv cov khoom txuag ua kom txo cov khoom siv tiv thaiv corrosion feem ntau los ntawm kev ntxiv cov txheej txheem tshuaj nruab nrab los hloov kho tus nqi ph. Hauv qhov kev txhim kho kom zoo ntxiv rau ib qho me me ntawm kev txhim kho corrosion, Cov Khoom Siv Hluav Taws Xob kom cov hlau saum npoo los ua cov yeeb yaj kiab tiv thaiv, uas tuaj yeem txo tus nqi ntawm xeb ntawm cov hlau. Yuav tuaj yeem tau txais qee qhov kev tiv thaiv xeb. Xws li stainless hlau, titanium thiab lwm yam hydrochloric acid, sulfuric acid thiab cov zoo li tsis-oxidizing acid corrosion tsis kam yog qhov tsis zoo, koj tuaj yeem ntxiv oxygen thiab nitric acid thiab lwm qhov me me ntawm cov oxidants kom txo tau qhov kev txhim kho ntawm cov khoom siv xeb thiab li rau.
Cov cuab yeej los tiv thaiv kev tiv thaiv rau txhua tus neeg' s ua haujlwm kom yooj yim, peb kuj yuav tsum tiv thaiv cov khoom siv tiv thaiv ua kom tsis txhob muaj tshuaj tiv thaiv cov khoom siv hluav taws xob, cov khoom siv Electrochemical peb to taub cov txuj ci saum toj no, Kuv ntseeg tias lub siab ntawm txoj kev daws teeb meem. Ntxiv rau, Rui tuaj yeem nco koj mus yuav khoom siv tiv thaiv xeb, mob siab rau cov khoom siv kom zoo, txo qhov txaus ntshai ntawm cov khoom siv xeb.
