Can PAC Be Used As Papermaking Additive?
1. Except for the breaking length, all other paper performance indicators have been improved to varying degrees.
2. Aluminum sulfate is only suitable for acidic sizing, while pac polyaluminum chloride can be used for sizing in acidic and neutral environments. The corrosion of the system is significantly weakened, and the treatment of white water is easier.
3. PAC polyaluminum chloride is a pre-hydrolyzate of aluminum chloride. The degree of hydrolysis is relatively low, and the decrease in pulp pH is smaller than that of aluminum sulfate.

4. Cheap calcium carbonate filler can be added, which not only reduces production costs and improves the whiteness and folding resistance of the paper, but also overcomes the inevitable shortcomings of synthetic sizing materials (such as AKD, etc.) (such as slipping and sizing) difficult to control, etc.).
5. PAC polyaluminum chloride has a white appearance and extremely low iron content, which can meet the needs of manufacturing high-quality paper.
6. Using polyaluminum chloride for sizing, the slurry's retention and filtering aid effects are significantly improved.
7. A large number of polynuclear aluminum hydroxyl complexes with positive charge and stable form can effectively promote flocculation and sizing.
