PAC is a white powder of aluminum hydroxide of high purity hydrochloric acid was spray-dried with the processing of a milk white or white fine powder-like, easily melts in air exposed.
High purity aluminum hydroxide powder and hydrochloric acid by spray drying or processing of a white fine powder-like white powder, melting easily exposed to the air. In recent years, white PAC has replaced the paper industry as aluminum sulfate precipitation neutral sizing agent.
White PAC - which compared with ordinary poly aluminum has the following characteristics: One, AL2O3 content is high, "30-33%
Second, the salt is low, only 50%, while the average degree of polymerization of aluminum salt is about 90%
Third, the water insoluble matter is small, only 0.3%, while the average poly aluminum more than 2%.
Fourth, pure white color, in addition to AL + outside does not contain any heavy metals, clear and transparent solution of the product water, there is no color, while the ordinary aqueous solution of poly aluminum color yellow or brown.
Fifth, the iron content is low, with low soluble characteristics, is used for oil-water separation project
White PAC - Note: 1, the product is acidic products, the absolute prohibition with an alkaline substance (such as bleach, lime, etc. ) along with storage, otherwise the product will fail.
2, solid product easy to absorb moisture, should be placed in a dry place for storage.
3, in the bags in good condition, shelf life of one year.
