Detailed Product Overview
Sodium Hexametaphosphate (Na6P6O18) is a highly effective inorganic compound known for its strong chelating properties. It appears as a white crystalline powder with a molecular weight of 611.76 g/mol and is readily soluble in water. This solubility facilitates its use in various aqueous formulations, particularly where ion sequestration is necessary. Sodium Hexametaphosphate is noted for its ability to complex with calcium and magnesium ions, which is crucial in preventing scale formation and enhancing the performance of cleaning agents. Its minimum P2O5 content of 68% underscores its high purity and effectiveness, making it a staple in industrial applications that demand reliable chemical interactions. In industrial settings, Sodium Hexametaphosphate is widely employed across diverse sectors such as water treatment, food processing, ceramics manufacturing, and detergent formulation. In water treatment, it acts as a water-softening agent by preventing the precipitation of calcium and magnesium salts, thus protecting equipment and pipelines from scale buildup. In food processing, it stabilizes textures and acts as a sequestrant, improving the quality and shelf-life of products. The ceramics industry utilizes this compound to disperse clay particles, enhancing the uniformity and quality of ceramic products. Its role in detergent formulation is to enhance cleaning efficacy by binding hard water ions, which improves the detergent's overall performance. When considering the procurement of Sodium Hexametaphosphate, it is essential to verify the industrial grade specification, which includes a minimum P2O5 content of 68% and a purity level that ensures optimal performance across applications. Buyers should also check for compliance with specifications related to heavy metals (max 0.01%), moisture content (max 5%), and chloride content (max 0.5%) to guarantee safety and quality. The bulk density should fall within the range of 0.6 to 0.8 g/cm³, and the pH of a 1% solution should be between 6.0 and 8.0, ensuring compatibility with various formulations and processes. Adherence to these specifications is critical for maintaining consistency and reliability in industrial processes. Handling and storage of Sodium Hexametaphosphate require careful attention to maintain its integrity and performance. It should be stored in a cool, dry place to prevent moisture uptake, which could affect its efficacy and shelf life. The compound is supplied in 25 kg polypropylene bags, which provide adequate protection against environmental factors during transportation and storage. When handling, appropriate safety measures should be observed due to its chemical nature. Kivi Industrial Chemicals Limited ensures that the product is delivered with consistent quality, adhering to stringent packaging standards that facilitate safe and efficient supply across the East African market, including Kenya, Uganda, and Tanzania.
