Performance and Applications:
1. Used as raw materials for cement admixtures and reinforcing agents in the building materials industry. The polycarboxylic acid high-efficiency water-reducing admixtures synthesized with this material exhibit strong cement particle dispersion retention, offering low dosage, high water-reduction rate, excellent reinforcement effect, durability, non-corrosive reinforcement steel, and environmental friendliness. Suitable for high-performance, high-strength (C60 and above) commercial concrete applications, both in-site mixing and long-distance transportation.
2. Soluble in water, ethanol, and organic solvents. Low vapor pressure, heat stable, used as a thickener and lubricant in the textile dyeing industry and daily chemical industry.
