Glass bottle spraying process
The spraying production line of glass bottles generally consists of a spray booth, a hanging chain and an oven. There is also the front-end water treatment for glass bottles, and special attention to the problem of sewage discharge for glass bottles. As for the spraying quality of the glass bottle, it is related to the water treatment, the surface cleaning of the workpiece, the electrical conductivity of the hook, the size of the air volume, the amount of powder spraying, and the level of the operator. It is recommended to choose the following method for trial: pre-treatment section
The pretreatment section of 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 insulation is required. Otherwise, the treatment effect is not ideal;
After pre-treatment, it must enter the preheating section, which generally takes 8-10 minutes. It is best to make the sprayed workpiece have a certain amount of residual heat when the glass bottle reaches the powder spraying room to increase the adhesion of the powder。
