Electrostatic Spraying: Trends in Quality Improvement and Solutions to Common Quality Problems

In an increasingly competitive market environment, the electrostatic spraying industry has an ever more urgent need to improve the quality of coatings. Meanwhile, some common quality problems also urgently need to be solved in order to meet the requirements of various industries for high-quality sprayed products. This article will elaborate on the trends in quality improvement and the ways to solve the problems in detail. 

• Trend of Quality Improvement : Nowadays, the electrostatic spraying industry is pursuing higher standards for coating quality. On the one hand, more stringent requirements are imposed on the microstructure and properties of coatings. For example, in the aerospace field, coatings are required to have extremely high hardness and wear resistance, as well as good thermal stability and chemical stability. Researchers improve the coating formula by adding special nanomaterials to make the microstructure of the coating denser, thereby enhancing various properties. On the other hand, the requirements for the appearance quality of coatings have also reached a new level. Consumers expect the surface of product coatings to be smooth, flawless, with uniform and long-lasting bright colors. To achieve this goal, enterprises adopt advanced automated spraying equipment and high-precision spray guns, combined with intelligent detection systems to monitor and adjust the spraying process in real time, ensuring the appearance quality of the coatings.

• Common Quality Problems and Solutions : The appearance of pinholes and bubbles in coatings is one of the common quality problems. This is mainly due to the mixture of air or water in the paint and incomplete pretreatment of the workpiece surface. The solution is to strictly control the environmental humidity during the storage and use of the paint to avoid water entering the paint. Meanwhile, strengthen the workpiece surface pretreatment process, adopt processes such as degreasing,   derusting , and phosphating to ensure that the workpiece surface is clean and dry. Insufficient coating adhesion is also a problem that troubles enterprises. This may be because the surface roughness of the workpiece is not enough or the affinity between the paint and the workpiece is poor. Enterprises can increase the surface roughness by sandblasting the workpiece surface to improve the paint adhesion. In addition, select appropriate primers or modify the paint to enhance the affinity between the paint and the workpiece.

• Development Direction of Industry Quality Control : In the future, the electrostatic spraying industry will further strengthen the quality control system. With the help of big data and artificial intelligence technologies, various data in the spraying process will be collected, analyzed and predicted, potential quality problems will be discovered in advance, and corresponding measures will be taken for prevention. Meanwhile, strengthen the formulation of industry standards and quality certification work to ensure the consistency and stability of product quality. 

Improving the quality of coatings is the core task in the development of the electrostatic spraying industry. By grasping the trends of quality improvement, effectively solving common quality problems and strengthening quality control, the industry can produce higher-quality products, meet the diverse needs of the market and enhance its own competitiveness.
