Process Flow

The Raymond Roller Galvanizing Passivation Equipment follows a comprehensive, multi-stage process designed to deliver optimal zinc coating quality and corrosion protection performance.

Loading & Pre-treatment

Small parts are loaded into specially designed barrels and undergo thorough cleaning processes including degreasing, acid pickling, and flux treatment to remove contaminants and prepare surfaces for optimal zinc adhesion.

Roller Galvanizing

Parts in rotating barrels are immersed in zinc electrolyte solution. Controlled electrical current facilitates uniform zinc deposition while barrel rotation ensures even coating distribution. Process parameters are continuously monitored and adjusted for optimal results.

Passivation Treatment

Following galvanizing, parts undergo passivation treatment to enhance corrosion resistance and appearance. Options include clear, yellow, or black passivation depending on application requirements and aesthetic preferences.

Rinsing & Drying

Multiple rinse stages remove residual chemicals, followed by thorough drying using heated air systems. Final inspection ensures coating quality meets specifications for thickness, appearance, and adhesion.

Roller galvanizing passivation equipment is an important equipment in the field of metal surface treatment, which is mainly used for electroplating and passivating metal parts to improve their corrosion resistance, abrasion resistance and aesthetics. The following is a detailed introduction of barrel galvanizing passivation equipment:

I. Equipment Overview

The barrel galvanizing and passivation equipment usually includes the main parts such as barrel plating machine, galvanizing tank, passivation tank, cleaning tank, drying machine and so on. This equipment makes the metal parts uniformly coated with zinc layer in the plating solution by barrel plating, and further improves the corrosion resistance of the plated layer by passivation treatment.

II. Working Principle

1. Roll plating process: The metal parts to be plated are placed on the roller of the roller plating machine, which is filled with a certain amount of plating liquid. With the rotation of the roller, the metal parts are rolled in the plating liquid to achieve uniform plating.

2. Zinc plating process: Zinc ions in the plating solution are deposited on the surface of the metal parts under the action of electric current, forming a dense zinc coating.

3. Passivation process: After galvanizing, the metal parts are fed into the passivation tank, and after contact with the passivation solution, a passivation film is formed on the surface of the plating layer to improve the corrosion resistance of the plating layer.

4. Cleaning and drying: The passivated metal parts are cleaned in the cleaning tank to remove the residual passivation solution on the surface, and then sent to the dryer for drying process.
