1, cov yam ntxwv ntawm cov hlau
Qhov corrosion ntawm hollow hniav tshuab ziab khaub ncaws feem ntau yog vim qhov tseeb tias hollow hniav tshuab ziab khaub ncaws yog ua los ntawm cov hlau, thiab cov tshuaj lom neeg ua haujlwm ntawm cov hlau kuj yog siab heev. Thaum cov hlau raug rau huab cua ntub ntev ntev, cov hlau yuav oxidize. , thiab thaum kawg corrosion tshwm sim. Lub hollow hniav tshuab ziab khaub ncaws yog ua los ntawm cov khoom siv hlau sib txawv, thiab lawv cov tshuaj tiv thaiv oxidation yooj yim sib txawv.
2, muaj pes tsawg leeg ntawm cov hlau
Lub purer cov hlau hollow hniav tshuab ziab khaub ncaws yog, qhov tsawg dua nws yuav corroded. Thaum muaj ntau impurities nyob rau hauv cov hlau, lub hollow hniav tshuab yog yooj yim corroded.
3. Qhov xwm txheej ntawm qhov chaw
Thaum cov duab ntawm cov khoom nyob rau hauv lub hollow hniav tshuab ziab khaub ncaws yog complex thiab nto yog rougher, corrosion kuj yuav phem dua. Cov hlau kuj corrode, thiab lawv corrode sai heev.
4. Ib puag ncig
Thaum qhov chaw ua haujlwm ntawm lub tshuab ziab khaub ncaws hollow yog kub thiab av noo, lossis yog tias muaj ntau cov pa oxygen thiab chloride ions nyob rau hauv ib puag ncig, nws yog ib qho yooj yim kom muaj cov tshuaj tiv thaiv nrog lub hollow paddle tshuab ziab khaub ncaws thiab ua kom cov qib corrosion ntawm qhov hollow. paddle tshuab ziab khaub ncaws.
