2. Key points of spraying process

1). Ensure the quality of surface treatment, including steps such as cleaning, rust removal and polishing. Surface treatment can not only improve the adhesion of the coating, but also ensure the appearance quality of the coating.

2). When spraying, pay attention to the distance and spraying speed between the spraying equipment and the surface of the object to be coated. Too close distance or too fast speed will cause uneven or too thick coating, affecting the quality of the coating.

3). Pay attention to the uniformity and consistency of the coating when spraying. The coating can be diluted or thickened as needed to ensure the fluidity and spraying performance of the coating.
