The spraying production line of glass bottles generally consists of spray chamber, suspension chain and oven. The glass bottle also has the front channel water treatment, the glass bottle particularly needs to pay attention to the sewage discharge problem. As for the quality of spraying glass bottle, it is related to water treatment, surface cleaning of workpiece, electrical conductivity of hook, gas volume, powder spraying and operator's level. The following methods are recommended for trial implementation:
Preprocessing segment:
The pre-treatment section of glass bottle spraying includes pre-detachment, main detachment, meter adjustment, etc. If it is in the north, the temperature of main detachment part can not be too low, so it needs heat preservation. Otherwise, the treatment effect is not ideal.
Preheating section:
It usually takes 8 to 10 minutes to enter the preheating section before and after treatment. When the glass bottle arrives at the powder spraying chamber, it should have some residual heat of the sprayed workpiece to increase the adhesion of the powder.
Purification section of glass bottle soot blowing:
If the process requirements of the sprayed workpiece are relatively high, this section is indispensable. Otherwise, if there is a lot of dust adsorbed on the workpiece, the surface of the processed workpiece will have a lot of particles, which will reduce the quality.
Drying section:
In this section, we should pay attention to the temperature and baking time. The powder is generally 180 - 200 degrees, depending on the material of the workpiece. Also, the drying oven should not be too far from the powder injection chamber, generally 6 meters is better.
Powder spraying section:
The key point in this section is the technical problems of the powder spraying master. If you want to create good quality, it's worth paying for a skilled master.
