Description

Technical Field

[0001] The utility model relates to the field of spraying for boxboard production, in particular to a spraying device for boxboard production. Background Art

[0002] The raw materials used in the production of corrugated board paper are usually tree pulp, various plant fibers, sulfate wood pulp, waste hemp pulp, cotton stalk pulp, waste paper pulp, rice and wheat straw pulp, etc. In the process of corrugated board paper manufacturing, fillers are also needed to improve the opacity, brightness, smoothness, printing adaptability, softness, uniformity and dimensional stability of the paper. It can also make the paper feel good, reduce its hygroscopicity, and reduce the amount of fiber. The pulp with fillers is easy to dehydrate and dry, which can reduce energy consumption, save 5%-30% of the amount of plant fiber used, and effectively reduce the cost of papermaking. Therefore, calcium carbonate solution is often used as filler in the process of producing corrugated board paper.
