Forming boards and vacuum suction boxes are critical components in the dewatering section of paper machines, designed to optimize the drainage process during paper formation. These elements are available in various materials and specifications, ensuring efficient moisture removal and enhancing the overall paper production process.
Key Features:
Material Options: Made from high-performance materials such as UHMWPE, HDPE, and PE, as well as polymer, ceramic, and alumina for the vacuum suction boxes, ensuring durability and optimal performance.
Thickness: Varies between 10-150 mm for forming boards and 3-300 mm for vacuum suction boxes, providing flexibility for different applications.
Porosity: < 0.04% porosity ensures minimal air resistance and efficient suction during dewatering.
Abrasion Resistance: With an abrasion rating of 70-80%, the forming boards offer strong resistance to wear and tear.
Surface Roughness: The surface roughness ranges between 0.3 - 0.5, ensuring effective moisture drainage while minimizing fiber damage.
Hardness: Forming boards exhibit a hardness range of 40-68, offering the necessary durability for high-pressure applications.
Breaking Strength: Forming boards have a breaking strength of 40-42 MPa, providing sufficient strength for long-term usage in demanding environments.
Molecular Weight: Materials feature a molecular weight between 0.5 - 9 million, contributing to the overall robustness and performance of the components.
Forming boards and vacuum suction boxes are primarily used in the paper and pulp industry to facilitate the dewatering process and support paper formation during manufacturing. These components help in controlling water content, ensuring that the paper reaches the desired consistency.
Applications Include:
Forming Board: Used in the forming section of paper machines to ensure the even distribution of pulp and facilitate efficient dewatering.
Vacuum Suction Box: Used in conjunction with forming boards to apply suction, aiding in the removal of excess water from the paper web during the forming and pressing stages.
Felt Suction Box: Works with the forming board and vacuum suction box in multi-stage dewatering processes to maintain optimal water removal and improve paper formation.
Paper and Pulp Industry: Essential for industries involved in paper production, particularly those that require high-efficiency dewatering for smoother, more consistent paper products.
