Problems solved by technology

[0002] Hot-dip galvanizing uses zinc ingots provided by smelters as raw materials, and various hot-dip galvanized alloys provided by alloy factories are melted into zinc liquid in a zinc pot, and the workpiece is put into the zinc liquid to galvanize the surface of the workpiece. , when the workpiece reaches a certain amount in the zinc pot, the zinc liquid in the zinc pot will have high iron content, high impurity content, poor fluidity, and particles, wrinkles, and coatings on the surface of the plated parts, which will cause the workpiece to be coated. The surface smoothness decreases, and the surface of the workpiece coating needs to be polished to meet the design requirements of the product, which increases the workload and production cost

Abstract

The invention discloses a zinc liquid cleanser. The zinc liquid cleanser comprises: by weight, 40 to 72% of CaF2, 3 to 15% of ZnCl2, 3 to 5% of C6Cl6, 20 to 30% of MgCl2.KCl and 2 to 10% of MnO2. The zinc liquid cleanser can be prepared through simple processes, has a low cost, is convenient for use, and has low iron content, low slag content, low gas content, high purity and good fluidity. The zinc liquid cleanser can be utilized for a treatment technology related to hot galvanizing melt. A galvanized part adopting the zinc liquid cleanser has good surface smoothness and no surface cockles. Therefore, the zinc liquid cleanser effectively improves product use performances and product quality.

Description

technical field [0001] The invention relates to a purifying agent, in particular to a zinc liquid purifying agent used in the related treatment process of hot-dip galvanizing melt. Background technique [0002] Hot-dip galvanizing uses zinc ingots provided by smelters as raw materials, and various hot-dip galvanized alloys provided by alloy factories are melted into zinc liquid in a zinc pot, and the workpiece is put into the zinc liquid to galvanize the surface of the workpiece. , when the workpiece reaches a certain amount in the zinc pot, the zinc liquid in the zinc pot will have high iron content, high impurity content, poor fluidity, and particles, wrinkles, and coatings on the surface of the plated parts, which will cause the workpiece to be coated. The surface smoothness decreases, and the surface of the workpiece coating needs to be polished to meet the design requirements of the product, which increases the workload and production costs.
