Rust yog qhov teeb meem nyob mus ib txhis uas tau paub txhua tus tswv tsheb thiab cov uas saib lawv lub tsev. Tsis tsuas yog cov hlau, xws li, tab sis kuj yog lawv cov txheej txheem sib txawv tau raug rau cov txheej txheem detrimental no. Vim kev ua ntawm cov huab cua hauv zos, corrosion tuaj yeem rhuav tshem cov khoom hlau. Qhov no nyeg yog fraught nrog teeb meem loj.
Matcast: Vim li cas koj thiaj li xav tau kev tiv thaiv
Nws yog fraught nrog kev rau txim loj heev.
Qhov tshwm sim ntawm xeb yuav muaj qhov tshwm sim deb. Yog hais tias tus txheej txheem corrosion pib, ces muaj txhua hli thiab xyoo nws yuav ua tsuas yog muaj kev ntxaws ntxiv xwb. Raws li qhov tshwm sim, qhov xeb yuav ua rau txo qis hauv kev ua haujlwm ntawm cov khoom lag luam hlau, cov khoom paug thiab cov txheej txheem, tso cai, thiab tseem ceeb tshaj plaws - mus rau kev poob nyiaj txiag loj.
Nyob rau hauv kev txiav txim rau txhua qhov no tsis tshwm sim, Kuv xav tau kev tiv thaiv tiv thaiv kev xeb.
1. Anticorrosion Txheej
Kev tiv thaiv yog qhov tseem ceeb heev.
Thaum xaiv lub cuab tam, nws yuav tsum tau yug los hauv siab tias nws yuav tsum muaj qhov siab tshaj plaws ntawm kev sib tw, muab qhov kev cuam tshuam tseem ceeb tshaj plaws, thiab tseem muaj tib yam (lossis kaw) nrog hlau Kev nthuav dav ntawm kev nthuav dav thermal.
2. Tsis Muaj Hlau Hlau Txheej
Qhov yooj yim txoj kev.
Tsim cov xim ua xim yog txoj hauv kev zoo los tiv thaiv cov hlau. Nws cov txiaj ntsig tseem ceeb yog kev khwv nyiaj txiag thiab yooj yim ntawm kev kho cov txheej tiv thaiv. Nws tseem yog ib qho tseem ceeb tias nws ib txwm muab lub sijhawm tshwj tseg los xaiv cov xim kom saj. Txawm li cas los xij, tus qauv tsis yog devoid ntawm qhov khuam. Feem ntau cov feem ntau, cov xim pleev xim thiab cov kua roj vanish ua rau tsis muaj zog tiv thaiv kom ya raws thiab kub, tsis txhob hais txog cov kev cuam tshuam tshuab.
3. Tsis yog xim hlau inorganic txheej
Kev tiv thaiv siab.
Ib qho ntawm cov hauv kev zoo tshaj los tiv thaiv cov khoom. Lub ntsiab lus ntawm txoj kev yog txo kom tsim zaj duab xis tiv thaiv ntawm tus qauv hlau. Rau qhov no, cov hlau yog them nrog oxide lossis phosphate zaj duab xis. Qhov thib ib yog thov yog tias khoom siv ntsuas geometry yuav tsum tau sab laug "tsis tau". Hom no yog siv, piv txwv li, thaum tiv thaiv riam phom thiab khoom siv raug. Qhov thib ob zaj duab xis yog tsim los ntawm kev txo cov khoom lag luam rau hauv cov kev daws zinc lossis manganese nrog qaub surts. Tom qab ntawd, xws li cov khoom lag luam tuaj yeem pleev xim.
4. Electrochemical tiv thaiv
Cov hau kev siv.
Txoj kev tiv thaiv no tiv thaiv corrosion yog siv tsuas yog cov hlau yog raug rau kev sib tw. Hom kev tiv thaiv no yog ob hom - cathode thiab anode. Thawj yog siv rau alloys nrog cov ntsiab lus hlau. Txoj kev tiv thaiv yog txo kom txuas cov khoom rau cathode projer. Hom thib ob ntawm kev tiv thaiv rau kev ntxuav thiab ua tiav los ntawm kev sib txuas cov khoom xeb rau cov khoom tam sim no.
