1,The spray production line of glass bottle is generally composed of spray room, hanging chain and oven.Glass bottles and the previous water treatment, glass bottles in particular need to pay attention to the problem of sewage discharge.As for the quality of bottle spraying, it is related to water treatment, surface cleaning of the workpiece, the conductive performance of the hook, the size of the air, the amount of dusting, the level of the operator.It is recommended to choose the following methods for trial: pretreatment section
The pre-treatment section of bottle spraying includes pre-stripping, main stripping, table adjustment, etc., if it is in the north, the temperature of the main stripping part can not be too low, the need for insulation.Otherwise the treatment effect is not ideal;
Preheating section

After the pre-treatment, it is necessary to enter the preheating section, which generally takes 8 ~ 10 minutes. It is best for the glass bottle to make the sprayed workpiece have a certain residual heat when it reaches the dusting room, so as to increase the adhesion of powder.
2,Bottle ash 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, the surface of the processed workpiece will have a lot of particles, so that the quality is reduced;
Drying section
What should be paid attention to in this section is the temperature and baking time. The powder is generally 180 ~ 200 degrees better, depending on the material of the workpiece.There are drying furnace from the dusting room should not be too far away, generally 6 meters as well.
Powder spraying period
The most critical part of this section is the technical problem of the dusting master. In order to create good quality, it is still worth paying for a good technical master
