The color is yellow or light yellow, dark brown, dark gray resin solid. The product has strong bridging adsorption performance. In the hydrolysis process, physical and chemical processes such as condensation, adsorption and precipitation occur. The fundamental difference between polyaluminium chloride and traditional inorganic coagulant is that the traditional inorganic coagulant is low molecular crystalline salt, and the structure of polyaluminium chloride is composed of polybasic carboxyl complex with variable morphology. It has fast flocculation and sedimentation speed, wide applicable pH value range, no corrosiveness to pipeline equipment, obvious water purification effect, and can effectively remove SS, COD, BOD, arsenic, mercury and other heavy metal ions in water The product is widely used in drinking water, industrial water and sewage treatment.
White poly aluminum chloride is known as high purity iron free white polyaluminum chloride or food grade white polyaluminium chloride. Compared with other polyaluminum chloride, it is the highest quality product. The main raw materials are high quality aluminum hydroxide and hydrochloric acid, and the production technology is the first technology spray drying method in the country. White polyaluminium chloride is used in many fields, such as sizing agent, sugar decolorization clarifier, tannery, medicine, cosmetics, precision casting and water treatment.
The raw materials of yellow polyaluminium chloride are calcium aluminate powder, hydrochloric acid and bauxite, which are mainly used for sewage treatment and drinking water treatment. Raw materials used for drinking water treatment are aluminum hydroxide powder, hydrochloric acid, and a little calcium aluminate powder. For the treatment of drinking water, the country has strict requirements on heavy metals, so it is better than Tan polychloride in raw materials and production process. Yellow polyaluminium chloride is usually produced by drum drying or spray tower drying. It has two solid forms, flaky and powdery.
