performance and application
1. In the building materials industry, it is used as the raw material of cement water reducing agent and reinforcing agent.
The high-efficiency polycarboxylate superplasticizer synthesized by using this raw material has a strong ability to maintain the dispersibility of cement particles, so that the product has the advantages of low dosage, high water reduction rate, good reinforcement effect, durability, non-corrosion of steel bars and environmental friendliness. Etc. It can be used in high-performance, high-strength (above C60) commercial concrete for on-site mixing and long-distance transportation.
2. Soluble in water, ethanol and organic solvents. Low vapor pressure, stable to heat, used as thickener and lubricant in textile printing and dyeing industry and daily chemical industry.
Packaging and storage
