Spray production line is generally composed of spray room, suspension chain and oven. Glass bottles and the former water treatment, glass bottles need to pay special attention to the problem of sewage discharge. As for the spraying quality of glass bottles and cans, it is related to water treatment, surface cleaning of the workpiece, the electrical conductivity of the hook, the size of the gas volume, the amount of powder spray, and the level of the operator. The following methods are recommended for trial:
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 the main stripping part can not be too low, and it needs to be insulated. Otherwise the treatment effect is not ideal;
2, preheating section. After pre-treatment, it is necessary to enter the preheating section, which generally takes 8-10 minutes, and the glass bottle is best to make the sprayed workpiece have a certain residual heat when arriving at the powder chamber to increase the adhesion of the powder;
3, glass bottle blowing ash 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 workpiece after processing will have a lot of particles, reducing the quality;
4. Powder spraying section. The most critical part of this section is the technical problem of the powder master, in order to create good quality, it is worthwhile to spend money on a good master;
5. Drying section. This section should pay attention to the temperature and baking time, the powder is generally 180-200 degrees is better, depending on the material of the workpiece. Also, the drying furnace should not be too far away from the powder spraying chamber, generally 6 meters is good.
