Introduction

The portable powder coating gun is a vital tool in the finishing industry, offering a more efficient and eco-friendly alternative to liquid coatings. Understanding its operation can enhance its application in various fields, ensuring optimal performance and cost-efficiency.

Working Principle of a Portable Powder Coating Gun

A portable powder coating gun utilizes the principle of electrostatic spray deposition. This process involves the following steps:

1. The coating powder is stored in a hopper and is fed into the gun through compressed air.
2. An electrostatic charge is applied to the powder particles within the gun, usually between 30,000 to 100,000 volts.
3. Charged particles are sprayed onto grounded metal surfaces, forming a uniform coating.
4. The coated material is then cured in an oven, bonding the powder to the surface.

Key Parameters and Numerical Analysis

The performance of a portable powder coating gun can be assessed based on several parameters:

• Voltage: Typically ranges from 30 kV to 100 kV.
• Gun Output: Commonly varies between 50 to 120 grams per minute depending on the model.
• Particle Size: Optimal powder particle size is between 10 to 100 microns for best adhesion and finish.
• Transfer Efficiency: A well-calibrated gun should achieve 60 to 70% transfer efficiency.
