Product Introduction

JZ-1 for Cyanide Zinc Plating Process

Property

Process Flow

Degrease alkaline chemically → wash with hot water → remove the rust with acid → wash → wash with running cool water → activate (hydrochloric acid) → wash → plate zinc → recycle → wash → neutralize (nitric acid 2-3%) → passivate → dry and solidify (60-80℃)
