1、 Product Introduction:
Spray drying typePolyaluminium ChlorideThe technical standards comply with the national GB15892-2003 standard, and the product appearance is high-end white and mid-range light yellow powder. The characteristics of spray drying PAC depend on the operating principle of pressure spray. The aluminum chloride produced by the pressure spray drying process is a small porous particle or a small hollow particle, showing dust-proof and smoothness. Due to better contact with the water to be treated, its wettability and water treatment speed are stronger than other powdered products. Spray production not only dries polyaluminum chloride, but also turns it into tiny particles. Polyaluminum chloride is a water-soluble substance that exhibits good thermal stability and solubility.
2、 Main technical indicators

3、 Product classification
1. spray drying PAC Grade I pure white polyaluminium chloride is used for water treatment, which can effectively remove all kinds of toxic and harmful pollutants in the water. The dosage is far lower than that of traditional inorganic coagulants, which can significantly improve the treatment efficiency and reduce operating costs.
2. High purity white polymerized chloride is used for paper sizing, which can be combined with rosin sizing agents to achieve neutral or even alkaline sizing, and can be filled with inexpensive calcium carbonate fillers. This not only reduces production costs, improves paper whiteness and folding resistance, but also overcomes the unavoidable disadvantages of synthetic sizing materials, such as slipping and difficult control of sizing degree. High purity white polyaluminum chloride also has good retention and filtration effects, which can effectively improve the water filtration performance and retention rate of the slurry.
4、 Product Usage:
1. Mainly used for the treatment of domestic drinking water, industrial water supply, oilfield reinjection water, circulating cooling water, and various types of wastewater (such as urban domestic wastewater, oily wastewater, printing and dyeing wastewater, papermaking wastewater, steel plant wastewater, etc.).
2. Paper sizing precipitant, sugar decolorizing and clarifying agent.
3. Used in multiple fields such as tanning, pharmaceuticals, cosmetics, and precision casting.
5、 Usage:
1. For polyaluminum chloride used in water treatment, in order to achieve the best use effect and economic benefits, users can determine the optimal dosage through experiments based on different water quality conditions. Dilute the AL2O3 percentage content of the product to a concentration of around 5% and add it.
2. For the use of polyaluminum chloride for papermaking sizing, its usage is the same as aluminum sulfate, with a dosage of one-third of aluminum sulfate, calculated as 2% -3% based on dry paper.
3. When used for decolorization and clarification in the sugar industry, the product is first prepared into a 3-5% aqueous solution (calculated based on the AL2O3 content), and then added to the sugarcane juice to be decolorized, with a dosage of 5-10 ppm. Both the inner and outer bags of the packaging are made of polypropylene film bags, weighing 20 kilograms per bag. Produce high-quality aluminum hydroxide refined hydrochloric acid as raw material.
6、 Attention:
1. When using this product, dilute it first and then add it. Liquid products can be directly diluted with water, while solid products can be dissolved in water and stirred evenly after adding water;
2. This product should not be mixed with drugs from different manufacturers or varieties, and should not be stored together with other chemical substances;
3. Solid products should be kept away from moisture, used immediately after opening the package, and avoid moisture absorption in the air. However, they can still be used after being damp, and their efficacy remains unchanged
7、 Product Features
1) 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 producing high-quality 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) The use of polyaluminum chloride for sizing significantly improves the retention and filtration effects of the slurry.
5) Except for the length of breakage, all other indicators of paper performance have been improved to varying degrees.
Spray drying polyaluminum chloride production process: spray drying: liquid raw materials - pressure filtration - spray tower spray drying - finished product drum drying: polyaluminum chloride has low corrosivity to pipeline equipment; Polyaluminum chloride is widely used in the fields of drinking water, industrial water, and wastewater treatment.
