Kungani ishidi lika-galvanized ligqwala?
I-zinc igqwalile ngokujwayelekile, ngaphandle kwalokho kusho ukuthi ipuleti le-zinc lingcolile futhi liqukethe ukungcola, okufana nensimbi. I-Zinc ivikela ezinye izinsimbi. I-zinc coating engalingani izoveza insimbi ngaphakathi futhi ibangele ukugqwala. Noma ungaqondile uxhumane nezinye izinsimbi ukuze wenze ukugqwala kwamakhemikhali.
Ishidi elinama-galvanized lingagqwala, kodwa ungqimba olunamanzi lufakwe i-oxidized kuqala ukuze kuvikelwe ipayipi lensimbi ekugqwaleni, futhi impilo yalo yesevisi yinde. Ngaphansi kwezimo zemvelo, isendlalelo se-chrome-plated ngeke sisabele nge-oxygen, i-carbon dioxide namanzi asemoyeni, futhi ngeke kugqweliswe ama-asidi abuthakathaka nama-alkali. Umphumela wayo wokulwa nokukholwa ungcono impela.
Ishidi elinothayela ngeke ligxume endaweni evamile, futhi lingase liphonswe ngenxa yokugcinwa okungafanele, ukukhuhla nokushayisana, ukungena kwamanzi kanye nokufuthwa kwesitimu. Isizathu esenza i-galvanized sheet igqwalile ukuthi i-zinc igqwalile ngokujwayelekile ukuvikela ezinye izinsimbi. Uma kungenjalo, ipuleti le-zinc lingcolile futhi liqukethe ukungcola, okufana nensimbi. Noma i-zinc enamathelayo ayilingani, iveza insimbi engaphakathi, ibangele ukugqwala, noma ixhumane nezinye izinsimbi ngokungaqondile, yenze ukugqwala kwamakhemikhali.
