- Product details
-
White polyaluminum chloride is a relatively special product of polyaluminum chloride, appearing as a white powder.
Production process:
White polyaluminum chloride: spray-dried powder, high aluminum oxide content, very low insoluble matter, and fast dissolution rate.
High product quality of the enterprise:
Spray-dried white polyaluminum chloride: aluminum oxide (Al₂O3) mass fraction/% ≥29%, generally can reach 29%-30% or more. The production raw material requirements are strict, made from pure raw materials such as aluminum hydroxide, in compliance with GB15892-2020 standards.
Product features:
1. Good water purification effect: floc formation is fast, and adsorption capacity is strong.
2. Wide range of applications: suitable for a wide pH range, with strong adaptability to water quality changes.
3. Convenience of use: low corrosiveness to equipment, good stability.
4. High purity and high content: aluminum oxide content is high, generally ≥29.5%, and can even reach over 30%, far exceeding ordinary polyaluminum chloride.
Uses
1. Paper industry: used for paper sizing in the paper industry, it can combine with cellulose in the paper to form a protective film, improving the water resistance of the paper and enhancing its whiteness and strength.
2. Food and pharmaceutical industry: due to its high purity and low impurity characteristics, it can be used as a water purification agent in food additives, and also for water treatment in the pharmaceutical industry, such as for the production of water for injection, meeting strict hygiene and quality requirements.
3. Cosmetics industry: as a water treatment agent, used in the water purification process during the production of cosmetics, ensuring high quality of water used in cosmetics, such as in the water treatment stage for producing toners, emulsions, and other products.Implementation standard (GB15892-2020):

The mass fractions of insoluble matter, iron, arsenic, lead, cadmium, mercury, and chromium listed in the table are calculated based on Al₂O₃ content of 10.0%. When Al₂O₃ content >10.0%, it should be converted to the proportion of products with Al₂O₃ content of 10.0%, and the corresponding mass fraction should be calculated. This product should also comply with relevant laws, regulations, and mandatory standards.
