[Performance and application]
1. HPEG series products are soluble in water and various organic solvents.
2. HPEG series products have high double bond retention rate, comb structure and large degree of freedom, and can be designed for molecular structure. The high performance water reducing agent can be produced by a relatively simple synthetic process.
3, HPEG series products have low dosage, high water reduction rate, good fluidity and flow retention of concrete mixture, and low slump loss. , the potential of enhanced effect and low shrinkage.
4, HPEG series products do not contain any harmful substances in the production and use process, excellent performance.
This product is mainly used to produce polycarboxylic acid high performance water reducer series products. Main application In concrete with high requirements for heat preservation, such as commercial concrete, mass concrete, self-leveling concrete, etc.; it is also widely used in major national engineering fields such as water conservancy and nuclear power.
