Polyaluminum chloride (PAC) is relatively stable under general conditions, but may decompose under extreme conditions such as high temperatures, strong acids, or strong bases. Here is some information about the stability of polyaluminum chloride:
Temperature stability: PAC is relatively stable at room temperature, but may decompose under high temperature conditions. High temperature may cause polymer chain breakage or other reactions, thereby affecting its performance. Therefore, during storage and use, it is necessary to avoid exposure to excessively high temperature environments.
PH stability: The stability of PAC is also related to the pH of the environment. Normally, PAC performs well in the range of neutral to acidic. Under high or low pH conditions, it may cause structural changes or loss of coagulation effect.
Interactions with other chemicals: PAC may interact with other chemicals, leading to changes in stability. Under certain special water quality or treatment conditions, it is necessary to consider its compatibility with other additives, ions, or organic compounds.
Photostability: Polyaluminum chloride has relatively low sensitivity to light and is generally not easily decomposed by light. However, prolonged exposure to strong sunlight may cause color changes, but this does not necessarily affect its function.
Storage conditions: In order to maintain the stability of polyaluminum chloride, it should be stored in a dry, cool environment and away from strong acids, bases, and other chemicals that may cause decomposition.
In practical applications, stability considerations are crucial for the correct selection and use of polyaluminum chloride. Manufacturers typically provide recommendations on product stability and optimal usage conditions, and users should store and use polyaluminum chloride according to these recommendations.
