Our core values are environmental protection and sustainability, and the key to achieve this is our technique to treat the products’ surface - we use electrostatic spraying, or powder coating, which avoids harmful components typically seen in traditional painting.
The process involves the application of a dry, solvent free finely ground powder to a surface, which is then heated to fuse the powder particles together and form a smooth, durable finish.Specifically, powder coating requires compliance with detailed and strict procedures. At our workshop, we have an interlocking, stringently executed production line divided into many steps.
Before powder coating, we need to remove impurities that may interfere with the coating's adhesion to the surface, and add some materials to make the coating more tightly bonded. After that, multiple washing and rinsing cycles are applied to remove remaining cleaning agents or other residues.
When all the conditions are set, steel panels are suspended on an overhead conveyor line, and an electrostatic spraying machine is used to spray a dry powder material on the surface of the panels. By electrostatic interaction, the powder will be evenly adsorbed on the surface to form a powdery layer. This powdery layer is then baked, leveled and cured at high temperature, and becomes the final coating with a range of good properties.
Advantages of powder coating include:
1. Powder coating does not contain solvents or volatile toxic substances, which is beneficial to the occupational health of workers at the production process, and also harmless to the environment and human body as a finished product.
2. The material utilization rate is high, with the excessive powder sprayed subject to recycling. The overall utilization rate during powder coating process is over 95%.
3. It also has excellent anti-corrosion properties, as this technique will form a hard, protective layer highly resistant to moisture, chemicals, and other environmental factors that can cause corrosion over time.
4. The powder coating process also has aesthetic advantages. It allows for a thicker, fuller coating layer and more even application of color. It also has a wide range of colors and textures of finishes for choice, with a variety of vibrant and lively colors, and glossy, matte or metallic styled surface qualities.
