1. Surface Coating: Used in layer-by-layer deposition techniques for surface coating.
2. Corrosion Inhibitor: Inhibit scale and corrosion in industrial recirculating water, boilers, and steam lines.
3. Oil and Mineral Exploration Auxiliary: Replace complexing agents in detergents, serve as a thinner for drilling fluid, and inhibit scale corrosion in reinjection water and pipelines.
4. Cleaning Detergent: Enhance water's soil-carrying capacity, prevent surfactant activity loss in hard water, and act as a dispersant in low-phosphate and phosphate-free detergents.
