    Performance and Applications

    1. Construction Industry:
      • Raw Material for Cement Additives: Used to synthesize polycarboxylate superplasticizers, which offer:
        • Strong dispersibility and retention of cement particles.
        • Low dosage requirement, high water reduction rate, and enhanced strength.
        • Durability, non-corrosion to steel reinforcement, and environmental friendliness.
      • Concrete Applications: Suitable for high-performance, high-strength (C60+) commercial concrete in on-site mixing and long-distance transportation.
    2. Textile, Dyeing & Daily Chemicals:
      • Soluble in water, ethanol, and organic solvents, with low vapor pressure and thermal stability.
      • Functions as a thickener and lubricant in textile dyeing processes and daily chemical products.

    Packaging and Storage

    • Packaging: 200 kg iron drums or 50 kg plastic drums.
    • Storage & Transportation: Non-flammable; store in a dry, ventilated area. Transport as general chemicals.
    • Shelf Life: 2 years under recommended conditions.
