Pre-treatment Equipment and Advantages


In order to enhance the effect of powder spraying, the surface of the sprayed workpiece must be clean. Good pretreatment allows the powder coating to bond better to the metal, withstand external weathering, and prevent the workpiece from rusting.


    1、Degreasing Equipment:


    Advantages: Removes oils, grease, and other contaminants from the surface, ensuring better adhesion of the powder coating. It helps in achieving a clean surface, which is essential for a successful coating process.


    2、Phosphating Equipment:


    Advantages: Phosphating creates a thin, adherent phosphate coating on the metal surface, which improves corrosion resistance and enhances the adhesion of the powder coating. It also provides a good base for subsequent painting processes.


    3、Rinsing and Drying Equipment:


    Advantages: After pre-treatment processes, rinsing and drying equipment ensure the removal of residual chemicals and moisture from the surface. Proper rinsing prevents contamination of the coating process, while thorough drying prevents issues such as blistering or delamination of the powder coating.

Advantages of Zhyao Pre-treatment Equipment : 


1. Using automated pre-processing can save a lot of manpower.

2. The use of spray pre-treatment can effectively reduce the length of the production line, thereby reducing the use of space.

3. The use of submersible pre-treatment can effectively reduce the length of the production line, thereby reducing the use of space, and can also clean the workpiece to ensure that there are no dead ends.

4. The top of the shed adopts a water-sealed design to isolate steam more thoroughly;

5. The shed body, cylinder body and spray pipes are all made of stainless steel and fully welded to ensure service life;

6. The entrance and exit of each process section are equipped with profiling baffles and matching transition sections to prevent liquid leakage;

7. The top is designed with an air trough, which can discharge the acid gas and steam accumulated at the top in time.
