Applications

1. Concrete Building Materials:

As a common water reducer, it offers a water reduction rate of 8-12%, lowers the water-cement ratio, enhances concrete strength (with early strength increased by 10-20%), improves workability, and reduces bleeding.
2. Oil Drilling:

Used as a mud dispersant to prevent clay particle agglomeration, stabilize drilling fluid rheology, and reduce fluid loss, suitable for water-based drilling fluid systems.
3. Dye/Pigment Industry:

As a dispersant, it adsorbs onto pigment particles to prevent agglomeration via electrostatic repulsion, enhancing color uniformity and storage stability in coatings and inks (e.g., for dispersing reactive dyes and carbon black).

4. Pesticides/Fertilizers:

• Pesticides: Acts as a dispersing aid in wettable powders to ensure uniform dispersion of pesticide particles in water, improving spraying efficiency.
• Fertilizers: Serves as a binder and dispersant in compound fertilizers to enhance granulation performance.

5. Water Treatment:

• Chelating Agent: Forms stable complexes with heavy metal ions (e.g., Fe³, Cu²) for industrial wastewater treatment.
• Scale Inhibitor: Used in circulating cooling water to inhibit the deposition of calcium carbonate and calcium sulfate.

6. Other Applications:

• Refractory Materials: Improves slurry fluidity and enhances the forming quality of green bodies.
• Ceramics Industry: Reduces glaze viscosity and prevents filler sedimentation.
• Activated Carbon Production: Acts as a forming binder to enhance the strength of carbon materials.
