Paper Machine Coating Blade

High Speed Paper Machine Coating Blade

In the paper industry, blade coating / creping is an important way to produce high quality paper, is a key part of the production process scraper quality also has a direct impact on product quality and production efficiency. The traditional doctor blade is used after oxidation of blue surface treatment of spring steel blade or tool steel belt manufacturing and become. With the coating machine to 1000m/min to 1500m/min or more high speed development, the need for wear-resistant coating of high quality doctor blade to meet the needs of high speed paper machine.

Application of Coating Blade

Coating blade is mainly used to control the thickness of the layer. According to the gap between the paper and the coating blade, different thickness layers can be achieved and the layers can be kept uniform to improve the smoothness and flatness, avoid bubbles and coating accumulation, and are often used in the production of coated paper.

Advantages of Coating Blade

• Uniform coating: As its primary function, this function can freely adjust the thickness of the coating to avoid uneven coating and cause the quality of paper to deteriorate.

• Avoid waste and reduce production costs: Accurately control the amount of coating materials to avoid unnecessary waste.

• Good paper quality: The coating blade can make the paper smoother, glossier and more printable, and is suitable for high-end paper

Sun Hong Coating Blades Unique Advantages

• Strong resistance to edge abrasion, long service life, more than 5 times that of ordinary scraper.

• High manufacturing precision, good surface flatness, can effectively reduce the roughness of the paper surface.

• It can run continuously and improve the stability of paper quality.
