Proper storage of 4A molecular sieve is critical to maintaining its adsorption performance and extending service life. Here are key steps to follow. First, always check the original packaging before storage. Ensure it’s sealed tightly to prevent moisture absorption, as even slight exposure to air can reduce its efficiency. For long-term storage, use airtight containers like metal drums or high-density polyethylene (HDPE) bins, which provide a barrier against humidity.
Storage environment matters most. Maintain a cool, dry place with relative humidity below 50%. Direct sunlight or high temperatures should be avoided, as they can cause thermal degradation. Adequate ventilation around the storage area helps prevent heat buildup, while远离火源 to ensure safety. If storing in industrial settings, avoid placing near packing or tower internal components that might introduce contaminants.
For opened 4A molecular sieve, use the product promptly. Once the seal is broken, reseal the container immediately after use and store in a dry environment. For unopened packages, follow the manufacturer’s expiration date, as 4A molecular sieve has a typical shelf life of 2-3 years when stored properly.
Regular inspections are necessary. Check for signs of moisture, such as clumping or discoloration, which indicate degradation. If any issues are found, consult a professional before reuse. By following these guidelines, you can preserve the adsorption capacity and effectiveness of 4A molecular sieve, ensuring optimal performance in applications like air drying, gas purification, and industrial separation processes.
