Spraying Process of Deep Processing of Glass Bottles
Spraying production line is generally composed of spray room, suspension chain and oven. Glass bottles need to pay special attention on the problem of sewage discharge. As for the quality of the glass bottle spraying, it is related to the water treatment, surface cleaning of the work-piece, the electrical conductivity of the hook, the size of gas, the amount of powder spraying, and the operator's level.The following methods are recommended for trial :
1. Pretreatment section. Pretreatment of glass bottle includes prestripping, main stripping, table adjustment, etc. If it is in the north of China, the temperature of the main stripping part should not be too low, insulation is needed.Otherwise, the treatment effect is not ideal.
2. Preheating section. After the pretreatment, it will enter the preheating section, which generally takes 8-10 minutes. The glass bottle had better make the sprayed work-piece have some residual heat when arriving at the powder spraying chamber, so as to increase the adhesion of the powder.
3. Dust blowing purification section. If the process requirements of the sprayed work-piece is needed to be higher, this section is essential. Otherwise, if there is a lot of dust adsorbed on the work-piece surface after processing, there will be a lot of particles, so that the quality is reduced.
4. Dusting section.The most important part of this section is the technical problem of the duster master. If you want to create good quality, it is worthwhile to pay for a skilled master.
5. Drying section.This paragraph should pay attention to is the temperature and baking time, powder generally 180-200 degrees is better, the specific degree depends on the work-piece. Plus drying oven apart from duster room unfavorable is not too far, 6 meters is better commonly.
