Sodium Lignosulfonate

Chemical Description 

• Sodium lignosulfonate from alkaline paper-making black liquor through concentration, filtration and spray drying, which belongs to construction raw materials.
• This product appears as brown powder or liquid with no special smell. It is non-toxic, being easily soluble in water and alkali.
• It undergoes precipitation upon coming across acid. Has a strong ability to disperse.
• It is mainly used as cement water-reducing agent, leading to the diffusion of a group of cement so that the water content is precipitated out, increasing its mobility, thereby reducing the mixing of water, and saving cement.
• When being used in the formulation of the oil drilling pulp, it can be used to reduce mud viscosity and shear force to control the mobility of drilling mud.
• neutralization reactions occur as the base accepts hydrogen ions that the acid donates. Neutralizations can generate dangerously large amounts of heat in small spaces.
• The dissolution of acids in water or the dilution of their concentrated solutions with water may generate significant heat
• It is mainly used as cement water-reducing agent, leading to the diffusion of a group of cement so that the water content is precipitated out, increasing its mobility, thereby reducing the mixing of water, and saving cement.
• When being used in the formulation of the oil drilling pulp, it can be used to reduce mud viscosity and shear force to control the mobility of drilling mud. In this case, the inorganic mud and inorganic salt impurities remain in the suspension state in the drilling, preventing the mud flocculation. It also has prominent salt resistance, anti-calcium and high temperature resistance.
• It can also be used as a concrete water-reducing agent, oil drilling mud dispersant, printing and dyeing and so on.
• Lignosulfonate is a water-soluble multi-functional polymer electrolyte, belonging to a lignin sulfonate and having the capability of dispersion of biological slime, oxidizing iron scale and calcium phosphate scale. It can also form a stable complex with zinc ions and calcium ions.
