An article analyzing the core advantages of powder coating in Dalian: fully revealed from process to application

Powder coating, as an innovative process in the field of surface treatment, is widely used in industrial manufacturing and consumption due to its unique technical principles and significant advantages. From the essence of craftsmanship to practical value, every aspect of it reflects the progress of modern painting technology.

The principle of process is the foundation of the advantages of powder coating. It adopts electrostatic spraying technology, which enables the insulation powder to carry negative charges under the action of the spray gun, adsorb to the surface of the grounded workpiece under the force of the electrostatic field, form a uniform coating, and then solidify at high temperature to melt, level and crosslink the powder into a film. Compared to traditional liquid coating, this process has no solvent volatilization and eliminates harmful gas emissions such as benzene and formaldehyde from the source, meeting strict environmental standards.

 

The core advantages make Dalian powder coating stand out. In terms of environmental friendliness, the utilization rate of powder coatings is over 95%, and unattached powders can be recycled and reused, achieving almost zero waste; In terms of efficiency, the powder solidification speed is fast, and hundreds of workpieces can be processed per hour under assembly line operation, greatly reducing the production cycle. In terms of coating performance, powder coatings have high hardness, strong wear resistance, and can withstand salt spray testing for over 1000 hours without rusting. They are widely used in outdoor guardrails, automotive wheels, and other fields. In addition, by adjusting the powder formula, diversified appearance effects such as matte and metallic texture can also be achieved.

The diverse applications further validated the value of powder coating. In home appliance manufacturing, after powder coating, the outer shells of refrigerators and air conditioners not only have long-lasting and bright colors, but also resist daily scratches; In the construction industry, aluminum alloy doors and windows are coated with powder coating, which can withstand acid rain and UV erosion, and extend their service life by more than three times. From process innovation to scene implementation, powder coating is reshaping the future of the surface treatment industry with comprehensive advantages.
