Features and performance:
- The content of aluminium oxide is high, up to >30%;
- Water insoluble matter is small, about 0.05%, and ordinary poly aluminium is about 1.5%;
- A large number of positive charges, and a stable shape, can effectively promote flocculation and sizing.
Application range:
White polyaluminum is used very little because of its high molecular weight molecular chain length. Particularly suitable for the raw materials of chemical intermediates. In recent years, white polyaluminum chloride has replaced aluminium sulfate as a neutral sizing precipitant for the paper industry.
