This article will introduce the technical principles and advantages of the application of blade coaters in oxidized wax coatings, and analyze its importance in the field of anti-corrosion coatings.

I. Introduction

As an important anti-corrosion coating material, oxidized wax coating has a wide range of applications in metal surface protection and decoration. As a common coating equipment, the blade coater uses a blade to evenly coat the coating material on the surface of the base material. It is one of the commonly used coating methods in the preparation process of oxidized wax coatings. This article will introduce the technical principles and advantages of the application of blade coaters in oxidized wax coatings, with a view to providing a reference for researchers and manufacturing companies in related fields.

2. Technical principles of application of blade coater in oxidized wax coating

The blade coater uses a blade to evenly coat the coating material on the surface of the base material. Its application technology principle is as follows:

Coating material supply: The oxidized wax coating material is delivered to the coating area through the supply system of the coating machine.

Blade coating: The coating material passes through the scraper of the coating machine and is evenly coated on the surface of the base material by the scraper to form a thin film.

Scraper adjustment: By adjusting the angle and pressure of the scraper, control the thickness and uniformity of the coating material on the surface of the base material.

Coating process: The base material moves through the motion system during the coating process to achieve uniform coating of the coating material on the entire base surface.

Curing treatment: The base material after coating is cured to form a stable oxidized wax coating film on the coating material.

3. Advantages of blade coater in oxidized wax coating

The blade coater uses a blade to evenly coat the coating material on the surface of the base material, which can achieve high coating uniformity. By adjusting the spacing and pressure of the scraper, precise control of the coating thickness can be achieved, which is suitable for the preparation of oxidized wax coatings with different thickness requirements. The coating machine is simple to operate and easy to control, and does not require complex operating techniques and equipment. The blade coater is equipped with different functions and can be applied to different types of base materials and coating materials, and has strong versatility and adaptability.

4. Conclusion

As a common coating equipment, the blade coater plays an important role in the preparation process of oxidized wax coating. Its advantages such as uniform coating, adjustable coating thickness, and easy operation make it widely used in the field of anti-corrosion coatings. Therefore, strengthening the research, development and application of blade coaters is of great significance for improving the quality and stability of oxidized wax coatings and promoting the innovation and development of anti-corrosion coating technology.
