Performance and application:
1. It is used in building materials industry as raw material of cement water reducing agent and reinforcing agent. The polycarboxylic acid superplasticizer synthesized from this raw material has strong ability to maintain the dispersion of cement particles, so that the product has the advantages of low dosage, high water reduction rate, good reinforcement effect, durability, no corrosion of reinforcement and environmental friendliness. It can be used in commercial concrete with high performance and high strength (above C60) for on-site mixing and long-distance transportation.
2. Polyethylene glycol monomethyl ether MPEG is soluble in water, ethanol and organic solvents. Steam pressure is low and stable to heat. It is used as thickener and lubricant in textile printing and dyeing industry and daily chemical industry.
