Tsis txhob cia cov lus nug
Txuas ntxiv mus haunt koj
Arc instability
Unsightly molding
Tshaj tawm ntau dhau
Nws yog feem ntau siv nyob rau hauv zus tau tej cov muaj zog acid yees,
tanks, pipelines thiab cia thiab thauj cov thawv
Nws tuaj yeem tiv taus corrosion ntawm sulfuric acid thiab phosphoric acid, thiab tiv taus cov
corrosion ntawm acetic acid nyob rau hauv tej qhov kub thiab txias thiab tej concentration nyob rau hauv ib txwm siab
Ripple zoo
Nws tuaj yeem daws cov teeb meem ntawm pitting corrosion,
crevice corrosion thiab kev nyuaj siab corrosion ntawm halides
Xws li arc ruaj khov, zoo nkauj sib sau, zoo ntws ntawm cov hlau kub, thiab cov txheej txheem vuam zoo heev.
