The technological process of glass bottle spraying
Jun 27, 2018

Glass bottle Spraying process spraying production line generally has spray room, hanging chain and oven composition. The glass bottle also has is the front road water treatment , specially needs to pay attention to is the sewage discharge problem. As for the quality of glass bottle spraying, that with water treatment, workpiece surface cleaning, the electrical conductivity of the hook, the size of gas, the number of dusting, the level of the operator. It is recommended that the following methods be chosen: 


1. Pre-processing section. Glass bottle spraying pretreatment section includes pre-stripping, main removal, table adjustment, etc., if it is in the north, the main part of the temperature can not be too low, need to heat preservation. Otherwise the treatment effect is not ideal;


2. Preheat section. Pre-treatment to enter the preheating section, generally need 8-10 minutes, glass bottles preferably in the powder room to be sprayed when the workpiece has a certain amount of residual heat, to increase the adhesion of powder, 


3. glass blowing ash purification section.

If the process of spraying the workpiece is relatively high, this section is necessary, otherwise the workpiece if the adsorption of a lot of dust, processing of the workpiece surface will have a lot of granular, so that quality reduction; 


4. Powder injection section. This section of the most critical is the powder dusting Master technical problems, to create good quality, spend money to ask the skilled master is still very well drawn; 


5. Drying section. This paragraph should pay attention to is the temperature and baking time, powder general 180--200 degree is good, specific to see the workpiece material.

There are drying furnace from the powder spray room is not too far, generally 6 meters for good.
