Technical Field

[0001] The utility model relates to the technical field of quantitative addition of passivating agents, in particular to quantitative addition equipment for hot-dip galvanized base alloy passivating agents. Background Art

[0002] Hot-dip galvanized base alloy passivator is a chemical substance applied to the surface of hot-dip galvanized base alloy to increase its surface corrosion resistance and oxidation resistance. It can form a protective oxide film to prevent the base alloy from contacting with oxygen, moisture, acid and alkali in the environment, thereby extending the use of the base alloy.

[0003] However, when the operator pours the passivator on the metal surface, since the adding equipment is mainly adjusted manually by the operator, there is a slight difference in the amount of passivator added each time, resulting in too much or too little passivator. Both of these situations greatly reduce the efficiency of subsequent coating of the passivator on the metal surface. Therefore, there is an urgent need for quantitative addition equipment for hot-dip galvanized base alloy passivator. Utility Model Content
