As a supplier of Polyaluminum Chloride for Coal Mine, I've had extensive experience with the product and understand the critical role that proper storage conditions play in maintaining its quality and effectiveness. In this blog post, I'll delve into the specific storage requirements for polyaluminum chloride in coal mines, providing you with a comprehensive guide to ensure its longevity and optimal performance.
Understanding Polyaluminum Chloride
Before we discuss storage conditions, it's essential to understand what polyaluminum chloride is and why it's used in coal mines. Polyaluminum chloride (PAC) is a highly effective water treatment chemical that is widely used in various industries, including coal mining. In coal mines, PAC is primarily used for water treatment purposes, such as clarifying coal mine wastewater, removing suspended solids, and reducing turbidity.
PAC is available in different forms, including powder and liquid. Polyaluminum Chloride Powder is a popular choice due to its ease of storage, transportation, and handling. It can be easily dissolved in water to form a solution that can be used for water treatment.
General Storage Guidelines
The storage of polyaluminum chloride in coal mines should adhere to certain general guidelines to prevent degradation and ensure its effectiveness. Here are some key points to consider:
1. Temperature Control
Polyaluminum chloride is sensitive to temperature changes. It should be stored in a cool, dry place away from direct sunlight and heat sources. High temperatures can cause the product to degrade, reducing its effectiveness and potentially leading to the formation of unwanted by - products. The ideal storage temperature for polyaluminum chloride is between 5°C and 35°C.
2. Humidity Control
Moisture can have a significant impact on the quality of polyaluminum chloride. Excessive humidity can cause the powder to clump together, making it difficult to dissolve and use. Therefore, the storage area should be well - ventilated and have low humidity levels. If possible, use dehumidifiers to maintain a relative humidity of less than 60%.
3. Protection from Contaminants
Polyaluminum chloride should be stored in a clean environment to prevent contamination. It should be kept away from chemicals, dust, and other pollutants that could react with the product and affect its quality. The storage containers should be tightly sealed to prevent the entry of foreign substances.
Storage of Polyaluminum Chloride Powder
If you're using Polyaluminum Chloride Powder, the following additional considerations apply:
1. Packaging
The powder should be stored in its original packaging or in high - quality, sealed containers made of materials that are resistant to corrosion, such as polyethylene or polypropylene. The packaging should clearly label the product name, grade, and batch number for easy identification.
2. Stacking
When stacking the powder containers, be careful not to stack them too high to avoid crushing the bottom containers. The stack should be stable to prevent it from toppling over. Leave enough space between the stacks for easy access and ventilation.
3. Shelf Life
Polyaluminum chloride powder has a limited shelf life. Generally, it can be stored for up to 12 months under proper storage conditions. After this period, the product may start to degrade, and its effectiveness may decrease. It's important to rotate the stock regularly to use the oldest products first.
Storage of Polyaluminum Chloride for Coal Mine
Polyaluminum Chloride for Coal Mine may have some specific requirements due to the nature of its use in coal mine water treatment.
1. Compatibility with Other Chemicals
In coal mines, there may be other chemicals used in the water treatment process. It's crucial to ensure that polyaluminum chloride is stored separately from incompatible chemicals. For example, it should not be stored near strong acids or alkalis, as these can react with PAC and cause chemical changes.
2. Safety Precautions
Since polyaluminum chloride is a chemical, proper safety precautions should be taken during storage. The storage area should be clearly marked with warning signs, and access should be restricted to authorized personnel only. Personal protective equipment (PPE), such as gloves and goggles, should be available in case of accidental contact with the product.
Storage of 28% Polyaluminum Chloride
28% Polyaluminum Chloride is a common grade used in coal mine water treatment. The storage requirements for this grade are similar to the general guidelines, but there are a few additional points:


1. Concentration Stability
The 28% concentration of polyaluminum chloride should be maintained during storage. Any changes in concentration can affect its performance in water treatment. Regularly check the concentration of the stored product to ensure it remains within the specified range.
2. Monitoring
Periodically monitor the stored 28% polyaluminum chloride for any signs of degradation, such as changes in color, odor, or solubility. If any abnormalities are detected, it's advisable to test the product before using it for water treatment.
Storage in Coal Mine - Specific Conditions
Coal mines have their own unique environment, which presents some challenges for the storage of polyaluminum chloride.
1. Dust and Particulate Matter
Coal mines are often dusty environments. The dust can settle on the polyaluminum chloride containers and potentially contaminate the product. To prevent this, the storage area should be separated from the main mining operations and should be equipped with dust - proof covers or enclosures.
2. Vibration and Shock
Mining operations can cause vibrations and shocks. These can potentially damage the storage containers and lead to spills or leaks. Ensure that the storage containers are properly secured and supported to withstand these vibrations and shocks.
Conclusion
Proper storage of polyaluminum chloride in coal mines is crucial for maintaining its quality and effectiveness. By following the guidelines outlined above, including temperature and humidity control, protection from contaminants, and specific storage requirements for different forms and grades of the product, coal mine operators can ensure that their polyaluminum chloride remains in optimal condition for water treatment.
