The air-cushion headbox is a core component of modern papermaking machines, primarily used in medium- and high-speed paper machines with speeds exceeding 200 meters per minute. By precisely controlling the air cushion pressure and pulp level, it evenly and stably sprays the pulp onto the wire mesh, directly determining the uniformity and strength of the paper.
Compared to the old-fashioned open headbox, the main advantages of the air-cushion type are accuracy and adaptability
1. High stability: Effectively isolates pressure fluctuations in upstream pulp, improving paper basis weight fluctuations by over 40%.
2. Wide applicability: Suitable for producing packaging paper, cultural paper, etc., with a wide basis weight range.
3. High maintainability: The contact surfaces between the box and the pulp are typically made of 304 stainless steel with a mirror finish, and the inner wall roughness reaches 0.4μm.
