Main properties and uses:
1.Used in the building materials industry as raw materials for cement superplasticizers and reinforcing agents. The polycarboxylate water reducer synthesized by using this raw material has a strong ability to maintain the dispersion of cement particles, so that the product has low dosage, high water reduction rate, good fruit increase, durability, no corrosion of steel bars and environmental friendliness, etc. advantage. It can be used in commercial concrete with high performance and high strength (above C60) 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.
3.It has good water solubility, wettability, lubricity, physiological inertia, non-irritating and mild to human body, and is widely used in cosmetics and pharmaceutical industries. Products with different molecular mass fractions can be selected to change the viscosity, hygroscopicity and organizational structure of the product. Products with relatively low molecular weight (molecular weight less than 2000) are suitable as wetting agents and consistency regulators, used in creams, lotions, toothpaste and shaving cream, etc. Products with a relatively high molecular weight are suitable for lipsticks, deodorant sticks, soaps, shaving soaps, foundations, and beauty cosmetics. In cleaning agent, it is also used as suspending agent and thickener.
4.Used as the base of ointment, emulsion, ointment, lotion and suppository.
5.It is the main raw material for preparing polycarboxylate cement superplasticizer.
