The output current range is 0~200μA. What impact does this current output have on the adsorption effect of powder coatings?

The output current range of Intelligent powder coating sprayer KFB-988 gemma G03G04 Powder Coating Machine is 0~200μA. This design parameter plays a vital role in the powder coating spraying process. It directly affects the adsorption effect of the powder coating and the final coating quality.

1. The influence of electrostatic current on the adsorption effect of powder coatings
The size of the electrostatic current directly determines the charge of the powder coating particles. During the high-voltage electrostatic spraying process, the discharge needle on the spray gun releases high-voltage static electricity, making the powder coating particles negatively charged. The greater the electrostatic current, the greater the charge of the powder coating particles. The increased charge of powder coating particles increases their adhesion to the grounded workpiece. This is because under the action of the electrostatic field, the negatively charged powder coating particles will be adsorbed by the positive electrode of the grounded workpiece.

2. The relationship between output current range and powder coating adsorption effect
Lower current range (0~50μA):
When the output current is in the lower range, the powder coating particles are relatively less charged. This may cause the movement of the powder coating in the electric field to slow down and the adsorption force to weaken, resulting in an uneven coating and even missing coatings. However, lower current can also reduce the risk of corona discharge and ensure the stability of the spraying process.

Medium current range (50~150μA):
Within this current range, the charge of the powder coating particles is moderate, which can ensure good adsorption effect and coating quality. Under the action of electric field, powder coating can be quickly and evenly adsorbed on the surface of the workpiece to form a continuous and dense coating. At the same time, this current range also has higher spraying efficiency and lower energy consumption.

Higher current range (150~200μA):
When the output current is in the higher range, the charge of the powder coating particles increases significantly. Although this can improve the adsorption speed and adsorption amount of powder coatings, excessive current can also easily lead to the occurrence of corona discharge. Corona discharge will not only reduce the charge and adsorption capacity of powder coatings, but may also cause damage to spray equipment and workpieces. In addition, excessive current may increase the thickness of the paint film and affect the appearance and performance of the coating.

3. Optimize the output current to improve the adsorption effect
In practical applications, the appropriate output current needs to be selected according to the specific spray materials and workpiece characteristics. Generally speaking, for workpieces with better conductivity and powder coatings with finer particle sizes, lower output current can be used; while for workpieces with poor conductivity and powder coatings with coarser particle sizes, the output current needs to be increased appropriately. Improve adsorption effect. At the same time, it is also necessary to pay attention to controlling parameters such as spraying distance, spraying pressure and spraying speed to ensure the stability of the spraying process and coating quality.

The output current range of Intelligent powder coating sprayer KFB-988 gemma G03G04 Powder Coating Machine is 0~200μA. This design parameter has an important impact on the adsorption effect of powder coating. In practical applications, the appropriate output current needs to be selected according to specific conditions to optimize the spraying effect and improve coating quality.
