Factors affecting the spraying quality of automatic powder spraying equipment

Powder spraying equipment is to make the surface of the product more than a layer of protective film, as customers have higher and higher quality requirements, many spraying companies will choose to use powder coating equipment to spray the surface of the product, but due to the continuous development of industry, manual has not reached the desired output, so there is automatic powder spraying equipment, and the application of automatic powder coating equipment is more and more extensive, deep into many areas of the national economy. Since many customers are not too familiar with this new type of powder spraying equipment production line, there will be many problems in the process of use, focusing on the quality of spraying, and talking about the factors affecting the assembly line spraying of powder spraying equipment.

First affect the quality of automatic powder spraying equipment spraying product factors is powder, we all know that there are many kinds of powder on the market, using different powder spraying, the output of the product is also different, and the resistivity of the powder is also different, generally more ideal 1010-1016 ohms / cm, lower ohms / cm resistivity is easy to produce powder dispersion, higher ohms / cm resistivity will also affect the thickness of the coating.

Secondly, the factors affecting the quality of spraying products of automatic powder spraying equipment are the amount of powder sprayed and the distance of spraying. The amount of powder sprayed has a certain effect on the film thickness of the sprayed product, and if the spraying amount is small, the surface deposition rate of the product will be higher. The amount of powder spray is generally controlled between 50 g/min and 1000 g/min. The spraying distance of the powder spraying equipment. Generally, it is controlled at a distance of 10-25 cm from the workpiece, mostly determined by the form of the spray gun. The coating distance is the main parameter affecting the thickness of the film, so it needs to be controlled.
