3. Manufacturing Process

Ceramic fiber paper is primarily made from ceramic fiber wool with low shot content and undergoes the following series of processes:

  1. Pulping: The ceramic fiber wool is beaten into a pulp to ensure uniform fiber dispersion.

  2. De-sludging: Impurities are removed from the pulp to ensure fiber purity.

  3. Pulp Blending: The concentration and composition of the pulp are adjusted as needed.

  4. Fourdrinier Forming: The pulp is evenly distributed on a Fourdrinier wire to form a thin fiber layer.

  5. Vacuum Dehydration: Excess water is removed through vacuum suction, allowing the fiber layer to take initial shape.

  6. Drying: The formed fiber layer is dried to remove remaining moisture.

  7. Cutting: The dried fiber layer is cut into the desired dimensions.

  8. Rolling: The cut ceramic fiber paper is rolled and packaged for easy transportation and use.
