Phosphorusterization in the pre -treatment of powder spray production: function and importance
In the pre-treatment phase of powder spray production, phosphorification is widely used.
Its role is not only to improve the adhesion of the coating, but also to ensure the quality and anticorrosiveness of the product surface.
This article will explore the role and importance of phosphorification in the process of the previous treatment.
1. Improve coating adhesion
As one of the key steps of pre -processing, one of its main functions is to form a uniform and dense phosphate layer on the surface of the workpiece. This layer of phosphorus film has improved the adhesion of the coating and the surface of the workpiece after the powder is sprayed to ensure that the coating is stable and stable on the surface of the workpiece to avoid problems such as peeling and foaming.
2. Increase surface corrosion resistance
The phosphorification layer formed by the phosphorification process has good corrosion resistance and can prevent the surface of the workpiece from being eroded from the surface of the workpiece to the surface of the atmosphere. This plays an important role in improving the service life and durability of the product, especially in harsh environments, such as humidity or corrosive climate.
3. Improve the painting effect
The formation of the phosphorization layer not only has a positive impact on the coating itself, but also provides a more ideal foundation for subsequent powder spraying. The uniform and dense phosphorus layer helps the powder evenly attach to the surface of the workpiece, thereby improving the uniformity and quality of the paint.
4. Reduce the defects of coating
Through phosphate, the possibility of defects can be effectively reduced, such as bubbles, peeling, peeling, etc. The formation of the phosphorurative layer fills the micro and unevenness of the surface of the workpiece, making the coating more flat and uniform, reducing the probability of problems in the painting process.
5. Environmental protection
Compared with some traditional anticorrosive coating methods, phosphoric acid phosphoric acid usually uses relatively environmentally friendly chemicals. This meets the requirements of modern industries for environmental protection and sustainable development, making production lines that use powder spray technology more sustainable.
Overall, phosphorus plays a vital role in the processing process of powder spray production.
By increasing coating adhesion, increasing surface corrosion resistance, improving the coating effect, and reducing coating defects, phosphorification ensures the quality and life of the product. It is an indispensable key step in the powder spray production line.
