Reduce The Degree of Environmental Pollution
With the increasingly strict regulations on the content of organic volatile compounds (VOCs) in the atmosphere under environmental protection laws, the coating industry has been trying to develop coating technologies that are more environmentally friendly. After long-term research and experimentation, it has been found that "electrostatic powder spraying" is currently the cleanest coating technology that can be achieved.
Powder coatings do not use volatile solvents such as organic solvents and water, and are inorganic solvent based coatings, which greatly reduces pollution caused by solvents, including poisoning incidents caused by the presence of organic solvents among operators; It will not cause fires due to organic solvents. Since the introduction of powder coatings, there have been no major safety accidents caused by powder coatings.
Powder coating is a pure solid component coating that can be completely sprayed automatically. Large quantities or overspray of powder can be easily collected by the recycling system to achieve the purpose of recycling and reuse. Therefore, the usage rate of powder coating can reach almost 100%, which reduces the cost of waste disposal in the coating industry and minimizes the degree of environmental pollution.
Significant Economic Benefits
Among the components formed by coating, solvent based coatings account for about 60% to 65%, while powder coatings can achieve almost 100% efficiency, and the powder that does not adhere to the sprayed object can be recycled and reused. In general, using powder coating technology can achieve the most economical and effective coating operation possible. In powder coating operations, if there are areas with poor spraying, they can be blown away with an air gun before baking, and then re coated. Therefore, it can avoid phenomena such as surface paint flow and dripping, greatly reducing the probability of repainting and rework. Due to the use of electrostatic spraying in powder coating, the coating equipment can almost achieve full automation, saving human resources. Even if manual assistance is required, painting personnel do not need to undergo long-term training to master operational skills. Powder coating is 100% solid and does not require the addition of any solvents, reducing the amount of coating, saving packaging, and reducing storage space.
Energy Conservation
Powder coatings, due to the absence of organic volatile compounds, avoid waste caused by volatilization into the atmosphere, thus significantly reducing energy costs compared to liquid coatings. Electrostatic spraying equipment can produce thick films in one spray, without the need for repeated spraying or primer, which is faster and more efficient than coating operations with the same film thickness. There is no need for static time in painting equipment, which can save equipment space. In addition, the baking time of powder coating is shorter than that of liquid coating, which can greatly reduce fuel and energy consumption, shorten the coating operation line, and improve production yield and efficiency.
Excellent Coating Performance
As long as the powder coating is directly sprayed onto the surface of the pre treated MDF board and baked, a high-performance coating surface can be obtained. Generally, powder coatings have long-lasting coating properties, including abrasion resistance, impact resistance, adhesion, toughness, corrosion resistance, and chemical resistance. In addition to the above advantages, powder coatings used outdoors also include high weather resistance and pollution resistance. A thick coating can be obtained by spraying powder coating in one go, with a film thickness between 50-300 μ m, and there is no dripping or accumulation phenomenon during thick coating of solvent coating.
Use electrostatic powder spraying equipment (electrostatic spraying machine) to spray powder coating onto the surface of the workpiece. Under the action of static electricity, the powder will uniformly adsorb onto the surface of the workpiece, forming a powdery coating; The powder coating undergoes high-temperature baking, leveling, and solidification to become the final coating with different effects (different types of effects of powder coatings).
