Powder coating is usually encountered during decoration, but people may still be unfamiliar with powder coating. Therefore, some recommended introductions about powder coating are also rejected. Powder coating enthusiasts will briefly introduce the basic knowledge of powder coating.
The so-called powder electrostatic spraying is based on the principle of high-voltage electrostatic corona electric field. Connect the high-voltage negative electrode to the metal guide vane at the head of the spray gun, and the sprayed workpiece is grounded to form a positive electrode, creating a strong electrostatic field between the spray gun and the workpiece. When compressed air is used as a carrier gas to deliver powder coating from the powder supply barrel to the guide rod of the spray gun through the powder tube, the corona discharge generated by the high-voltage negative electrode connected to the guide rod generates dense negative charges near it, causing the powder to carry negative charges and enter a high electric field strength electrostatic field. Under the dual action of electrostatic force and carrier gas, the powder uniformly flies towards the surface of the grounded workpiece to form a thick and uniform powder layer, which is then heated and solidified into a durable coating film. Here are some basic characteristics of powder coatings.
1. This product does not contain toxicity, solvents, or volatile toxic substances, so there are no issues of poisoning, fire, or discharge of "three wastes" and other public hazards, fully complying with the requirements of national environmental protection laws.
2. The utilization rate of raw materials is high. Some well-known brand powder suppliers produce powders whose overspray can be recycled, and the highest utilization rate can even reach over 99%.
3. After pre-treatment of the coated material, it can be applied in one go without the need for a primer to obtain a sufficiently thick coating film, which is easy to achieve automated operation, has high production efficiency, and can reduce costs.
4. The coating is dense, with good adhesion, impact strength, and toughness, high coverage of edges and corners, and excellent chemical corrosion resistance and electrical insulation performance.
5. Powder coating storage, transportation safety and convenience.
After reading the above introduction, I believe everyone's understanding of powder coatings has further improved. In fact, there are many advantages of powder coatings, which are excellent wall coating materials. Powder coating manufacturers should pay attention to increasing publicity efforts to let more people know about powder coatings. As long as everyone understands them, they will be impressed by the various properties of powder coatings.
