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.
