Core Industrial Applications<\/h3>\n

1. Petrochemical & Molecular Sieve Synthesis<\/b><\/h4>\n

As a high-purity aluminum source, the 50# grade is ideal for the production of zeolites and molecular sieves<\/b>. Its high reactive alumina content ensures efficient crystallization and structural integrity for petroleum hydrocarbon transformation catalysts and carriers.<\/p>\n

2. High-Performance Construction Chemicals<\/b><\/h4>\n

Used as a premium concrete accelerator<\/b>, especially in shotcrete and rapid-repair mortars. The high concentration allows for lower addition rates while achieving faster setting times in challenging underground or low-temperature environments.<\/p>\n

3. Advanced Water Treatment<\/b><\/h4>\n

Effectively used for silica removal and as a secondary coagulant to enhance the removal of heavy metals and suspended solids. It adds necessary alkalinity to the system, optimizing the coagulation-flocculation process.<\/p>\n

4. Specialty Chemical Manufacturing<\/b><\/h4>\n
    \n
  • Titanium Dioxide:<\/b> Provides a high-density alumina coating to improve pigment durability.<\/li>\n
  • Refractory Materials:<\/b> Acts as a high-strength bonding agent in refractory cement and castables.<\/li>\n
  • Paper & Textile:<\/b> Functions as a high-efficiency filler and antistatic agent in synthetic fiber production.<\/li>\n<\/ul>\n
    \n

    Quality Control & Packaging<\/h3>\n

      Frequently Asked Questions (Technical Support)<\/h3>\n

      Q: What makes the 50# model different from the 48# or 35#?<\/strong><\/p>\n

      A: The 50# model contains the highest concentration of active Aluminum Oxide (\u2265<\/span><\/span>50.0%) and Sodium Aluminate (\u2265<\/span><\/span>80.0%). This means you get more reactive power per kilogram, making it more cost-effective for high-volume chemical synthesis and heavy-duty construction projects.<\/p>\n

      Q: How does the molar ratio (1.30\u00b10.05) affect performance?<\/strong><\/p>\n

      A: This precise caustic ratio ensures that the product remains highly stable during storage and provides a predictable, high-pH reaction environment when dissolved, preventing premature precipitation in sensitive catalyst formulations.<\/p>\n

      Q: What is the shelf life of the 50# solid product?<\/strong><\/p>\n

      A: When stored in a cool, dry place in its original sealed packaging, the product typically has a shelf life of 12 months. Due to its hygroscopic nature, it is vital to keep the bags tightly closed.<\/p>\n
