The thickness of spray coating processing can be controlled through the following steps:
1 Determine the surface treatment requirements for the workpiece: Determine the thickness range of the required coating based on the product requirements
2 Choose the appropriate coating: Select the appropriate coating based on the material and surface treatment requirements of the workpiece. Different coatings have different viscosity, solid content, and construction process requirements, which need to be selected according to the actual situation
3 Adjusting the parameters of the spray gun: During the spraying process, it is necessary to adjust the parameters of the spray gun, including the distance, running speed, and powder supply, to ensure the thickness and uniformity of the coating
4 Control the viscosity and solid content of the coating: The viscosity and solid content of the coating have a significant impact on the thickness and uniformity of the coating. Therefore, it is necessary to properly mix and filter the coating before use to ensure the quality and stability of the coating
5 Control the temperature and humidity of the workpiece: The temperature and humidity of the workpiece also have a significant impact on the thickness and uniformity of the coating. Therefore, it is necessary to perform appropriate pre-treatment on the workpiece before spraying to control the temperature and humidity of the workpiece
6 Regular inspection and maintenance of equipment: Regularly inspect and maintain spraying equipment, including spray guns, powder feeders, and filters, to ensure the normal operation of the equipment and the quality of the coating In short, thickness control in spray coating processing needs to be approached from multiple aspects, including surface treatment requirements for workpieces, selection of coatings, adjustment of spray gun parameters, control of coating viscosity and solid content, control of workpiece temperature and humidity, as well as equipment inspection and maintenance. By implementing appropriate control measures, the desired coating thickness and uniformity can be achieved
