Spraying production line generally consists of spray room, suspension chain and oven. The glass bottle also has the front road water treatment, the glass bottle specially needs to pay attention to is the sewage discharge question. As for the spraying quality of glass bottles, the same water treatment, clean up the surface of the workpiece, the conductive properties of hook, volume size, the number of operators for dusting, level. It is recommended that the following methods be selected for Trial Implementation:

1, pre-processing 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 main stripping part can not be too low, need to keep warm. Otherwise, the effect is not ideal.

2, preheating section. It usually takes 8-10 minutes for the glass bottle to enter the preheating section after pretreatment. It is better for the glass bottle to have a certain amount of waste heat when it reaches the powder injection chamber to increase the adhesion of the powder.

3. Glass bottle soot cleaning section. If the sprayed workpiece process requirements are relatively high, this section is essential, otherwise if there is a lot of dust adsorbed on the workpiece, the surface of the processed workpiece will have a lot of granular, so that the quality of the lower;

4, dusting section. This technical problem is the key to master the dusting, creating excellent quality, pay good master is very excellent;

5. Drying section. This section should pay attention to the temperature and baking time, powder generally 180 - 200 degrees is better, depending on the material of the workpiece. And the drying furnace is not too far away from the powder chamber, generally 6 meters.
