Alkaline zinc-iron alloy electroplating liquid and electroplating process thereof

Abstract

The invention belongs to the technical field of alkaline zinc-iron alloy electroplating liquid, and particularly relates to alkaline zinc-iron alloy electroplating liquid and an electroplating processthereof. An electroplating device comprises an electroplating box and a drying box. Evenly formed first through holes are formed in the inner wall of the drying box. An air pump is arranged in the inner wall of the drying box. The end faces of the two sides of the electroplating box are fixedly connected with transmission mechanisms. Evenly formed sliding grooves are formed in the inner wall of the electroplating box. According to the alkaline zinc-iron alloy electroplating liquid and the electroplating process thereof, the problems that in the zinc-iron alloy electroplating process of a current electroplating device, usually a zinc-iron alloy is directly placed in the electroplating liquid to be electroplated; due to the fact that the electroplating liquid is static in the electroplatingbox, the electroplating speed of the zinc-iron alloy is low, and the electroplating effect of the two faces of the zinc-iron alloy is uneven; and after zinc-iron alloy electroplating is finished, inthe zinc-iron alloy collecting process, an electroplated layer on the zinc-iron alloy is usually scratched, and defects and wrinkles are generated on the electroplated layer on the zinc-iron alloy aremainly solved.

Description

technical field [0001] The invention belongs to the technical field of alkaline zinc-iron alloy electroplating solution, in particular to an alkaline zinc-iron alloy electroplating solution and an electroplating process thereof. Background technique [0002] As one of the effective steel surface protection processes, galvanizing has been widely used in the protection of steel components, accounting for about 1 / 3 to 1 / 2 of the entire electroplating industry. However, with the development of science and technology, the requirements for the use of coatings are getting higher and higher. On the basis of galvanizing, zinc-based alloy coatings and zinc-based composite coatings have been developed. Zinc-based alloy coatings include Zn-Ni, Zn-Fe, Zn-Co, Zn-Cu, Zn-Mn, etc. Among them, the zinc-iron alloy coating has been studied and applied most because of the wide source of iron and low cost. Zinc-iron alloy coatings are divided into low-iron zinc-iron alloy coatings and high-iron...

AI Technical Summary

Problems solved by technology

[0006] In order to make up for the deficiencies in the prior art, the present invention proposes an alkaline zinc-iron alloy electroplating solution and its electroplating process. Electroplating in the liquid, because the electroplating solution is in a static state in the electroplating box, resulting in a slow electroplating speed of the zinc-iron alloy, and the electroplating effect on both sides of the zinc-iron alloy is uneven. It will scratch the electroplating layer on the zinc-iron alloy, causing defects and wrinkles on the electroplating layer on the zinc-iron alloy
