Description

Technical Field

[0001] The utility model relates to the technical field of thin film processing, in particular to a coating uniformity device for a release film base film. Background Art

[0002] When coating the release film base film, uneven coating can lead to inconsistent performance in different areas of the product. For example, uneven protective coating may make some areas more susceptible to corrosion or wear.

[0003] For decorative coatings, uneven coating will affect the appearance quality of the product, resulting in inconsistent visual effects such as color and gloss.

[0004] Uneven coating thickness will affect the overall thickness control of the product, which is particularly important in certain precision manufacturing fields because the thickness directly affects the function and adaptability of the product.

[0005] The uniformity of the coating can also affect the durability and lifespan of the product. An uneven coating may be more prone to peeling or degradation in certain areas, shortening the overall lifespan of the product.

[0006] Uneven coating may result in poor adhesion in some areas, which may cause peeling during use.

[0007] Therefore, ensuring coating uniformity is crucial to guaranteeing product quality and performance. Summary of the Invention
