1. Chloride galvanizing is a bright galvanizing process developed in the early 1980s. The characteristics of the chloride bath:

A, it is a single-salt bath without complexing agent, and the wastewater is easy to treat.

B, the brightness and leveling of the coating are better than its bath system.

C, the current efficiency is high, and the deposition fast speed.

D, hydrogen overpotential.

Low steel such as high carbon steel, castings, forgings, etc. are easy to coat.

2. Chloride galvanizing bath composition:

A, zinc chloride.

B, potassium chloride.

C, boric acid.

D, add agent (main brightener, carrier brightener, auxiliary brightener).
