The process flow of glass bottle spraying The spraying production line generally consists of a spray booth, a hanging chain and an oven. The glass bottle and the front water treatment , in particular, need to pay attention to the problem of sewage discharge. As for the quality of glass bottle spraying, it is related to water treatment, surface cleaning of the workpiece, 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: preprocessing section. The pre-treatment section of glass bottle spraying includes pre-stripping, main stripping, surface adjustment, etc. If it is in the north, the temperature of the main stripping part should not be too low, and it needs to be kept warm. Otherwise, the treatment effect is not ideal; preheating section. After the pretreatment, it will enter the preheating section, which generally takes 8-10 minutes.
It is best for the glass bottle to have a certain amount of residual heat on the sprayed workpiece when it reaches the powder spraying room, so as to increase the adhesion of the powder. Glass bottle soot blowing purification section. If the process requirements of the workpiece to be sprayed are relatively high, this section is essential. Otherwise, if a lot of dust is adsorbed on the workpiece, the surface of the workpiece after processing will have a lot of particles, which will reduce the quality; powder spraying section.
The most critical part of this section is the technical problem of the powder spraying master. If you want to create good quality, it is still very worthwhile to spend money on a skilled master. drying section. What should be paid attention to in this section is the temperature and baking time. The powder is generally 180–200 degrees, 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.
