Brush plating zinc equipment is a portable electroplating device used for localized zinc plating. It utilizes a brush soaked in electroplating solution as the anode and moves it across the surface of the workpiece. Through electrolysis, zinc ions are deposited onto the workpiece surface, forming a zinc coating.
1. Equipment Composition:
Power Supply: Provides direct current (DC) and controls the electroplating current and voltage.
Anode Brush: Typically made of graphite or stainless steel, wrapped in a material (such as cotton cloth or sponge) that absorbs the electroplating solution.
Electroplating Solution: An electrolyte solution containing zinc ions, with a formula that varies depending on the specific requirements.
Cathode Connection Wire: Connects the workpiece to the cathode of the power supply.
Auxiliary Equipment: Includes cleaning agents, rust removers, polishing tools, etc., for pre-treatment and post-treatment of the workpiece.
Control System: (Optional) Used to precisely control parameters such as current, voltage, and plating solution temperature.
2. Working Principle:
Workpiece Preparation: The workpiece first needs to be cleaned, degreased, and derusted to ensure good adhesion between the coating and the substrate.
Connect Power: Connect the workpiece to the cathode of the power supply, and the anode brush to the anode of the power supply.
Wet the Anode Brush: Immerse the anode brush in the electroplating solution to fully saturate it.
Brush Plating: Move the anode brush across the surface of the workpiece while applying direct current. Under the influence of the electric field, zinc ions migrate from the electroplating solution to the surface of the workpiece and are reduced to metallic zinc at the cathode (workpiece surface), forming the coating.
Post-Treatment: After zinc plating, the workpiece is cleaned, passivated, etc., to improve the corrosion resistance and appearance of the coating.
3. Advantages:
Portability: The equipment is small, lightweight, and easy to carry, making it suitable for on-site repairs and localized zinc plating.
Selective Plating: Only the areas that need to be zinc plated can be coated, saving plating solution and time.
Simple Operation: Relatively simple to operate, without requiring large equipment or complex processes.
Lower Cost: Compared to traditional immersion zinc plating, equipment and material costs are lower.
Repair Capability: Suitable for repairing damaged zinc coatings or patching local defects.
Cold Galvanizing: Belongs to chemical and physical galvanizing, with no damage to the substrate.
4. Applications:
On-Site Repair: Used for repairing localized zinc coatings on facilities such as bridges, pipelines, and steel structures.
Zinc Plating of Welded Areas: Used to zinc plate welded areas to prevent corrosion.
Zinc Plating of Large Workpieces: For large workpieces that cannot be placed in an electroplating tank, brush plating can be used for localized zinc plating.
Mold Repair: Used to repair zinc coatings on mold surfaces.
Artwork Production: Used to perform localized zinc plating on metal artwork to enhance aesthetics.
How to Choose Brush Plating Zinc Equipment:
When choosing brush plating zinc equipment, consider the following factors:
Zinc Plating Area and Shape: Select the appropriate anode brush size and shape according to the area and shape that needs to be zinc plated.
Zinc Plating Thickness Requirements: Select the appropriate power supply and electroplating solution according to the zinc plating thickness requirements.
Equipment Power: Choose the appropriate equipment power according to the workpiece size and zinc plating speed.
Brand and After-Sales Service: Choose a reputable brand with good after-sales service.
Price: Consider the cost-effectiveness of the equipment and choose equipment that fits your budget.
Summary:
Brush plating zinc equipment is a convenient and fast tool for localized zinc plating, suitable for various on-site repair and special applications. When choosing and using brush plating zinc equipment, you should fully understand its advantages, disadvantages, and precautions, and choose the appropriate equipment and process according to your actual needs to ensure coating quality and operating safety.
