Device and method for zinc-plating steel wire for colored coating, and the zinc-plating steel wire

Abstract

The present invention provides a manufacture device and method of lackluster zinc-plating wire for pigmentation and a kind of zinc-plating wire according to the above mentioned method. The mentioned manufacture device can maximize the alloy layer and minimize the pure zinc layer, also can maintain the uniform coating and improve the pigmentation of the wire surface. The above mentioned zinc-plating wire consists of Fe layer, alloy layer and pure-zinc layer. The characteristics of the mentioned zinc-plating wire is that the thickness of the alloy layer is more than the one of the pure-zinc layer, and the prominence part forms on the mentioned pure-zinc layer surface.

Description

technical field [0001] The present invention relates to a dull galvanized steel wire for colored coating, and in particular to a production device and a manufacturing method of a dull galvanized steel wire capable of maximizing the alloy layer and minimizing the pure zinc layer and improving the colored coating on the surface, And the galvanized steel wire manufactured by the method and the device. Background technique [0002] Generally, as shown in FIG. 1, galvanized steel wire B is subjected to plating (or coating) treatment of alloy layer (Fe+Zn) 102 and pure zinc layer (Zn) 104 on the surface of Fe layer 100, as the plating There are electro-galvanizing methods and hot-dip galvanizing methods. [0003] The electrogalvanizing method can adjust the current efficiency of the surface and the roughness and gloss of the surface particles by using additives in the solution. Unlike the hot-dip galvanizing method, the electrogalvanizing method is characterized in that the zinc ...

Problems solved by technology

[0006] However, the above-mentioned hot-dip galvanizing method is very difficult to control the pure zinc layer and the alloy layer. Not only that, the deviation of the plating adhesion is greater than the deviation of the plating adhesion of the electro-galvanizing method, and the adjustment of the roughness of the surface particles and There are many difficulties in gloss

In addition, in the hot-dip galvanizing method, it is difficult to paint on the surface of the uneven and thick pure zinc layer, and the plating layer and the coating layer are not dense, so that peeling occurs, so it is difficult to paint on the surface of the colored coating. use in purpose

[0007] Particularly with the galvanized steel wire B that above method is manufactured, as shown in Figure 1, the thickness of pure zinc layer 104 is uneven, and the thickness of pure zinc layer 104 is far thicker than the thickness of alloy layer 102, therefore, is difficult for coloring coating , In addition, when performing this coating operation, there is a problem that a uniform surface cannot be formed
