White polyaluminum chloride is a white powdery fine powder formed by spray drying with active aluminum hydroxide and high hydrochloric acid, and the alumina content is more than 29%. The basicity of white polyaluminum is low, only 50%, and the basicity of ordinary polyaluminum is about 90%. Because of the low basicity, white polyaluminum is used in pure water and mineral water, with low turbidity and good effect. , The water-insoluble matter is ultra-low, the color is white and pure, the aqueous solution is clear and transparent after the product is used, and there is no other color, while other polyaluminum is yellow or brown. The iron content is low, and it has the characteristics of low temperature dissolution. It is particularly effective in making paper instead of aluminum sulfate. Adding cheap calcium carbonate fillers can reduce production costs, improve the whiteness and folding resistance of paper, and overcome problems. The inevitable disadvantages of synthetic rubber.
White polyaluminum has good solubility, condenses into flocculent in water, and settles quickly. The effect of purifying water is better than other flocculants, and the cost of purifying water is also 15-30% lower. The least amount of flocculants can achieve the best results. Flocculants from different manufacturers cannot be mixed and stored, let alone stored with other chemicals. The products should be stored in a dry, ventilated and cool place indoors to prevent moisture. Generally used in drinking water and food, paper sizing and precipitation, urban dome.
