Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, and more specifically, to an antibacterial powder coating grinding device. Background Technique

[0002] Antibacterial powder coating is a coating with special functions. It can form an antibacterial layer on the surface of the coating, effectively inhibiting and killing the growth of microorganisms such as bacteria and molds. During the preparation process of powder coatings, particles with uneven sizes, such as being too thick or too thin, may appear. These uneven particles will affect the performance of the coating, such as adhesion, color, and gloss. Seriously, it will lead to quality problems such as coating peeling, flaking, and spotting. Therefore, grinding is one of the important links to ensure the coating quality and painting effect.

[0003] In the existing technology, as disclosed in the document with the publication number CN220716178U, a grinding device for powder coatings is specifically disclosed. In the device in this document, the powder coatings are ground by the grinders in the grinding box. However, the grinding process needs to be repeated. When the powder coatings in this device fall on the two grinders, only single - time grinding can be achieved at this time, which is likely to cause insufficient grinding and affect the quality of the powder coatings. For this reason, we propose an antibacterial powder coating grinding device. Content of the Utility Model
