The quality of the spraying is related to water treatment, surface cleaning of the workpiece, the conductivity of the hook, the small amount of air, the amount of powder sprayed, and the level of the operator. It is recommended to choose the following methods for trial implementation: 1. Pre-processing section. The pre-treatment section of the glass bottle spraying includes pre-off, main off, surface adjustment, etc. If it is in the north, the temperature of the main off part should not be too low, and it needs to be kept warm. Otherwise, the treatment effect is not ideal; 2. Preheating section. After pre-treatment, it will enter the preheating section, which generally takes 8 to 10 minutes. When the glass bottle reaches the powder spraying room, it must have a certain residual heat of the workpiece to increase the adhesion of the powder; 3. The glass bottle is blown Ash purification section. If the process requirements of the sprayed workpiece are compared, this section is indispensable, otherwise if there is dust on the workpiece, the surface of the processed workpiece will be more granular, which reduces the quality; 4. Powder spraying section. The key to this section is the technical problem of the powder spraying master. In order to create good quality, it is still worthwhile to ask the skilled master to spend money 5. The drying section. At this stage, the temperature and baking time should be paid attention to. The powder is generally 180 to 200 degrees, depending on the material of the workpiece. Also, the drying furnace should not be too far from the powder spraying room, generally 6 meters is better.
