How to improve the smoothness of ivory board paper?

Improving the smoothness of ivory board paper can be approached from the following aspects:

Optimizing papermaking processes: By refining process parameters such as pulp fineness, paper machine speed, pressing, and drying conditions, the fibers in the paper can be arranged more tightly, resulting in a smoother paper surface.

Utilizing surface treatment techniques: Such as coating and calendering. Coating involves applying a layer of coating on the paper surface to make it smoother and finer; calendering uses mechanical pressure to compact the surface fibers of the paper, enhancing smoothness.

Choosing high-quality raw materials: Premium fiber materials can produce more uniform pulp, thereby contributing to the smoothness of the paper.

Enhancing post-treatment of paper: For example, using supercalendering machines for further calendering treatment to improve the smoothness of the paper surface.

Controlling the moisture content and humidity of the paper: Appropriate humidity and moisture levels help maintain the flatness and stability of the paper, indirectly improving smoothness.

Using smoothing agents: During the papermaking process, adding certain smoothing agents can help improve the smoothness and glossiness of the paper surface.

Improving smoothness is not simply achieved by increasing surface coatings or treatments; it involves multiple aspects such as papermaking processes, raw material selection, mechanical equipment, and chemical usage. Therefore, in practical production, suitable processes and measures need to be developed based on specific circumstances to achieve the optimal balance between cost and benefits.
