In the industrial field, powder spraying is a widely used surface coating technology. Among them, soaking and electrostatic types are two common spraying methods. 

This article will deeply explore the principles and operation steps of these two methods to help understand and choose processes applicable to different needs.

Plastic spraying principle

Plastic spraying is a spray method that is completely immersed in the liquid powder and then cured by baking.

principle:

1. The workpiece is prepared, which usually includes cleaning and surface treatment to ensure that the powder attachment is firm.

2. The liquid powder is usually plastic powder with granularity, which may contain pigments and auxiliary agents.

3. The workpiece is hung on a fixed rack, and then is completely immersed in the liquid powder to ensure that the coating is evenly covered with the surface.

4. After the immersion is completed, the workpiece is improved, and the excess powder is removed by vibration or air spraying to keep the coating evenly.

5. Finally, the workpiece is baked through the baking room to quickly solidify the liquid powder to form a solid coating.

Plime spray operation steps

1. Prepare workpieces: cleaning and surface treatment workpieces to ensure clean and smooth surfaces and help the adhesion of coating.

2. Placing process: Hang the workpiece on a fixed frame, completely immerse in the liquid powder to ensure that the coating is evenly attached to the surface of the workpiece.

3. Vibration or air get rid of excess powder: raise the workpiece, and get rid of the excess powder from the surface through vibration or air injection to ensure evenly coating.

4. Baking: Send the coating workpiece into the baking room for baking to quickly solidify the powder and form a solid surface coating.

Electrostatic spray principle

Static spraying is a spraying method that uses the charge effect to make the powder more easily attached to the surface of the workpiece.

principle:

1. Through a special electrostatic spraying gun, the powder is charged and becomes a positive charge.

2. The workpiece is grounded and becomes a negative charge.

3. Due to the attraction of charge, the charged powder particles quickly adsorb on the surface of the workpiece to form uniform coating.

4. Excess powder recovered by filtering system.

Static spray operation steps

1. Preparation workpiece: cleaning and surface treatment to ensure that the surface is suitable for coating attachment.

2. Powder spraying: Use electrostatic spray guns to spray the charged powder evenly on the surface of the workpiece.

3. charge attraction: Due to the attraction of charge, the powder particles quickly adsorb on the surface of the workpiece to form coatings.

4. Baking: Send the coating workpiece into the baking room for baking to quickly solidify the powder and form a solid surface coating.

Through in -depth understanding of the principles and steps of immersion and electrostatic spraying, manufacturers can better choose technologies applicable to their production needs and ensure high -efficiency and high -quality surface coating.
