Properties

It is mainly used as cement water reducing agent to make the agglomerated cement diffuse, the moisture content precipitates and increase its fluidity. So as to reduce mixing water and save cement. When it is used in oil drilling mud formulation, it can effectively reduce mud viscosity and shear force, so as to control the fluidity of drilling mud, keep inorganic mud and inorganic salt impurities suspended in drilling, prevent mud flocculation, and have outstanding salt resistance, calcium resistance and high temperature resistance. It is also used in dispersing agents such as dyes, wax emulsions, pigments, water treatment and cleaning agents.
