The spraying production line is generally composed of a spraying room, a suspension chain and an oven. The glass bottle also has the front water treatment. The glass bottle needs to pay special attention to the sewage discharge. As for the spraying quality of glass bottles and cans, it is related to water treatment, surface cleaning of workpieces, conductivity of hooks, air volume, amount of powder spraying, and the level of operators. China Glass Bottle Trading Network suggests the following methods for trial implementation:
1. Pre processing section. The pretreatment section of glass bottles before spraying includes pre stripping, main stripping, surface conditioning, etc. If it is in the north, the temperature of the main stripping section cannot be too low, and it needs to be kept warm. Otherwise, the treatment effect will not be ideal;
2. Preheating section. After pretreatment, it will enter the preheating section, which generally takes 8-10 minutes. When the glass bottle arrives at the powder spraying room, it should make the sprayed workpiece have a certain amount of residual heat to increase the adhesion of powder foam;
3. Glass bottle soot blowing purification section. If the process requirements of the sprayed workpiece are relatively high, this section is essential, otherwise if there is a lot of dust adsorbed on the workpiece, there will be many particles on the surface of the processed workpiece, which will reduce the quality;
4. Powder spraying section. The key to this section is the technical problem of the dusting master. To create good quality, it is worthwhile to pay for a skilled master;
5. Drying section. What should be noted in this section is the temperature and baking time. Generally, 180 - 200 degrees is preferred, depending on the material of the workpiece. Also, the drying furnace should not be too far away from the powder spraying room, generally 6 meters is better.
