Sodium lignosulfonate

Sodium lignosulfonate is a yellowish to brown, water-soluble, amorphous powder or granular solid with no characteristic odor and low volatility; it decomposes rather than melts at elevated temperatures. It is a sulfonated, anionic polymeric aromatic compound derived from lignin, a natural component of wood. Primarily used as a dispersant, binder, and emulsifier, it serves as a functional additive in concrete admixtures, agrochemical formulations (e.g., wettable powders and suspension concentrates), and dye preparations. Typical application areas include construction chemicals, crop protection products, ceramics, and leather tanning.

1,It is mainly used as cement water-reducing agent, leading to the diffusion of group of cement so that the water content is precipitated out, increasing its mobility, thereby reducing the mixing 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.2,It can also be used as concrete water-reducing agent, oil drilling mud dispersant, printing and dyeing and so on
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.
