Sodium lignosulfonateUsage
1. It is mainly used as a cement water-reducing agent, so that the bulk cement is diffused, and the moisture content precipitates and increases its fluidity. So as to reduce mixing water and save cement. It can effectively reduce the viscosity and shear force of drilling mud, control the fluidity of drilling mud, keep inorganic mud and inorganic salt impurities in a suspension state during drilling, prevent mud flocculation, and have outstanding salt resistance, calcium resistance, and high-temperature resistance.
2. Used as concrete water reducer, oil drilling mud dispersant, printing and dyeing diffuser, etc.
3. Dispersants for dyes, wax emulsions, pigments, water treatment, and cleaning agents.
