4. Product Highlights

• Excellent Water Softening: STPP efficiently removes calcium, magnesium, and other hard water ions by forming complexes, preventing scale formation and improving the efficiency of detergents and cleaning agents.
• Effective Dispersing Agent: STPP is a powerful dispersant for minerals, clays, and dirt particles, helping to prevent their redeposition during industrial cleaning and washing applications.
• Buffering Capacity: It helps maintain a stable pH in various systems, making it ideal for applications in food processing, water treatment, and pharmaceuticals.
• Enhanced Cleaning Power: In detergents, STPP significantly boosts cleaning efficiency, especially in hard water conditions, by improving the solubility of active ingredients.
• Environmental Compatibility: Compared to other chemicals, STPP is relatively environmentally friendly and less harmful, making it a sustainable option for industrial applications.

5. Detailed Usage Methods

1. Water Treatment:
   STPP is commonly used as a water softener in industrial water treatment processes. It effectively removes hardness ions like calcium and magnesium from water, reducing scaling and improving the performance of boilers, cooling towers, and other water systems. The recommended concentration is typically 1-5 g/L, depending on the water quality.

   Example: In an industrial boiler system, adding STPP helps to prevent the buildup of scale, increasing thermal efficiency and extending the lifespan of equipment.

2. Detergents and Cleaning Agents:
   In the manufacturing of household and industrial cleaning products, STPP is a key component that enhances the detergency and cleaning power, especially in hard water. It is typically added at concentrations of 5%-20% in detergents, laundry powders, and dishwashing liquids.

   Example: A laundry detergent manufacturer using STPP found a 30% improvement in cleaning performance, especially in regions with hard water.

3. Food Processing:
   STPP is used in food processing, particularly in seafood and meat products, where it serves as a preservative, water-retaining agent, and enhancer of texture. It helps maintain moisture, improve appearance, and extend shelf life. The typical usage concentration is below 0.5%.

   Example: In a seafood processing plant, adding STPP to shrimp and fish processing improves texture and prevents water loss during freezing, maintaining quality and weight.

4. Textile and Paper Industry:
   STPP is used in textile dyeing and finishing processes as a dispersing agent for dyes, as well as in the paper industry to stabilize pulp and improve paper quality. It prevents the deposition of unwanted particles, ensuring smoother processes and better final products.

   Example: A textile manufacturer added STPP to their dyeing process and noticed improved dye dispersion and more vibrant color output.

5. Fertilizer Industry:
   In the production of fertilizers, STPP serves as a source of phosphorus, enhancing the effectiveness of phosphate-based fertilizers. It also improves the solubility of nutrients, making them more readily available to plants.

   Example: A fertilizer producer used STPP in combination with other phosphatic materials to increase the nutrient uptake of plants, resulting in higher crop yields.
