Spraying process of the glass jar
The spraying production line of glass cans generally consists of spray booths, hanging chains, and ovens. Glass tanks also have front-line water treatment. Special attention to glass tanks is the problem of sewage discharge. As for the spraying quality of glass jars, it is related to water treatment, surface cleaning of workpieces, the electrical conductivity of hooks, air volume, powder spraying, and the level of operators. It is recommended to choose the following method for trial: Pre-treatment section
The pre-treatment section of glass tank spraying includes pre-release, main release, surface adjustment, etc. If it is in the north, the temperature of the main release part should not be too low, and heat preservation is required. Otherwise, the treatment effect is not ideal;
After the pretreatment, it will enter the preheating section, which generally takes 8 to 10 minutes. It is best to make the sprayed workpiece have a certain amount of residual heat when the glass jar reaches the powder spraying chamber, so as to increase the adhesion of the powder.
