Yuav ua li cas aluminium-muaj thiab aluminium-free zinc melts txawv hauv lawv cov teebmeem corrosion ntawm hlau

Thaum cov kav hlau tau muab tso rau hauv zinc rau ib lub sijhawm luv luv, tus nqi corrosion nyob rau hauv aluminium-free galvanizing pots yog kwv yees li 7-9 zaus sai dua li hauv txhuas-muaj galvanizing pots. Txawm li cas los xij, thaum lub sij hawm immersion tshaj 8 feeb, tus nqi corrosion nyob rau hauv aluminium-muaj galvanizing pots ua siab tshaj qhov uas nyob rau hauv aluminium-free pots. Cov qub tau txais txiaj ntsig zoo rau kev tsim cov khoom lag luam sai sai ntawm zinc immersion, thaum yav tas los muaj kev cuam tshuam tsis zoo rau galvanizing pots. Yog li ntawd, nyob rau hauv qhov tseeb ntau lawm siv txhuas-ntxiv galvanizing pots, nws yog pom tias cov pits corroded rau hauv cov hlau daim hlau ntawm galvanizing pots ntawm zinc kua nto yog ntxaum.
