Abstract
The invention relates to a manufacturing method of increasing zinc coating hardness for electro-zinc coated sheet. The procedures of the manufacturing method are as follows: a steel sheet undergoes the processes of degreasing, water cleaning, and acid cleaning; afterwards, the surface of the steel sheet is galvanized and galvanized solution is added with tin of 15 to 8000ppm. The manufacturing method has beneficial effects that the surface of the zinc coating is flat and smooth and has no stripe and good bonding force.
Description
Technical field
The present invention relates to a kind of electrogalvanizing steel plate method that increases rigidity of galvanizing layer of making.
Background technology
Electrogalvanizing steel plate is widely used in household electrical appliance, automobile and material of construction, and existing plating zinc steel plate is because the problem of electroplating technology causes rigidity of galvanizing layer on the low side, and forming property is relatively poor.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of electrogalvanizing steel plate method that increases rigidity of galvanizing layer of making is provided.
Technical scheme of the present invention is: a kind of electrogalvanizing steel plate method that increases rigidity of galvanizing layer of making, it is characterized in that: concrete steps are as follows: steel plate is carried out skimming treatment, use clear water rinsing, cleanup acid treatment thereafter, thereafter the surface of steel plate electro-galvanizing after processing adds the tin that contains 15-8000ppm in electroplating solution.
Beneficial effect of the present invention: smooth, bright, the no striped of zinc coating surface quality, bonding force are good.
Embodiment
Embodiment: a kind of electrogalvanizing steel plate method that increases rigidity of galvanizing layer of making, concrete steps are as follows: steel plate is carried out skimming treatment, thereafter use clear water rinsing, cleanup acid treatment, the surface of steel plate electro-galvanizing after processing adds the tin that contains 15-8000ppm in electroplating solution thereafter.
