As a traditional water purification agent, basic aluminum chloride still has good use effect and excellent market demand. General basic aluminum chloride has solid basic aluminum chloride and liquid basic aluminum chloride. Today, let's briefly introduce basic aluminum chloride.

The quality of basic aluminum chloride is related to its basicity, preparation method, raw material, impurity and content. The color of liquid basic aluminum chloride will change with its alkalinity, generally between 40% and 60% is light yellow transparent liquid, when the alkalinity exceeds 60%, it is mostly colorless transparent liquid. The basicity of solid basic aluminum chloride will also change with the basicity. The basicity of solid basic aluminum chloride is below 30%, and it is in the form of fine particles. When the basicity is between 30% and 60%, the particles become larger. When the basicity is more than 60%, it is in the form of glass or resin. Once the alkalinity exceeds 70%, it is easy to form insoluble particles, so the alkalinity cannot exceed 70% in the solid production of basic aluminum chloride.

The content of basic aluminum chloride refers to the composition of alumina in basic aluminum chloride. Generally speaking, the higher the content of basic aluminum chloride, the better the product quality. The content of basic aluminum chloride is generally determined by raw materials and production process, which is closely related to the alkalinity of basic aluminum chloride. The insoluble substance of basic aluminum chloride refers to the impurities contained in the production of basic aluminum chloride. Generally, the lower the content of insoluble substance, the better the quality of basic aluminum chloride products.
