Food grade white polyaluminum chloride
A white or milky white powdered fine powder made of aluminum hydroxide powder and high-purity hydrochloric acid by spray drying, which is easily melted when exposed to the air.
Product Introduction
A white or milky white powdered fine powder made of aluminum hydroxide powder and high-purity hydrochloric acid by spray drying, which is easily melted when exposed to the air. In recent years, white polyaluminum chloride has replaced aluminum sulfate as a neutral sizing and precipitation agent in the paper industry.
Product Description: Milky white powder
Product Features
1、 High AL2O3 content 29.5%
2、 The basicity is low, only 50%, while the basicity of ordinary polyaluminum is around 90%
3、 Water insoluble substances are small, only 0.3%, while ordinary polyaluminum has more than 2%.
4、 The color is pure and white, without any heavy metals except AL+. After the product is hydrated, the aqueous solution is clear and transparent, without any color, while the color of ordinary polyaluminum aqueous solution is yellow or brown.
5、 Low iron content and easy solubility at low temperatures,
High purity polyaluminum chloride (solid)
Solid pure white PAC
Alumina content: 30%
Application areas: Paper industry, pharmaceuticals, sugar refining, cosmetic additives, daily chemical industry
Product Description: In addition to purifying drinking water, urban water supply, and precision manufacturing water, it has a wide range of applications, especially in the paper industry, pharmaceuticals, sugar refining, cosmetic additives, and daily chemical industry.
White polyaluminum chloride has replaced aluminum sulfate as a neutral sizing and precipitation agent in the paper industry. Compared with aluminum sulfate, white polyaluminum chloride has the following characteristics:
A large number of positively charged and morphologically stable multi-core aluminum hydroxide complexes can effectively promote flocculation and sizing.
2) The appearance is white, with extremely low iron content, which can meet the needs of manufacturing paper.
3) Polyaluminum chloride is a pre hydrolyzed product of aluminum chloride, with a relatively low degree of hydrolysis, and the decrease in pH value of pulp is smaller than that of aluminum sulfate.
4) Aluminum sulfate is only suitable for acidic sizing, while polyaluminum chloride can be used for sizing in acidic and neutral environments, significantly reducing corrosion to the system and making white water treatment easier.
5) Low cost calcium carbonate fillers can be added, which not only reduces production costs, improves paper whiteness and folding resistance, but also overcomes the unavoidable disadvantages of synthetic rubber materials (such as AKD), such as slipping and difficult control of sizing degree.
6) The use of polyaluminum chloride for sizing significantly improves the retention and filtration effects of the slurry.
7) Except for the length of breakage, all other indicators of paper performance have been improved to varying degrees.

usage method:
Solid products need to be dissolved and diluted before being released. Users can adjust the concentration of the agent through experiments based on different water qualities to determine the optimal dosage.
① Solid state products account for 2-20%.
② The dosage of solid products is 1-15 grams per ton,
The specific dosage shall be subject to flocculation testing and experiments.
Packaging and Storage:
The solid is packaged in 25kg bags, with an inner plastic film and an outer plastic woven bag. The product should be stored indoors in a dry, ventilated, and cool place, and should not be damp. It is strictly prohibited to store it together with flammable, corrosive, or toxic substances.
