Application

1.Sodium Lignosulfonatemainly 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.

2.Sodium Lignosulfonate used in the formulation of the oil drilling pulp, can 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.

3.Sodium lignosulfonate also can be used as animal feed additive or animal feed pellet binder.

The benefits of lignosulfonates in animal health are remarkably similar to those in the soil. Where humic acids help to balance the critical fungal:bacteria ratio in the soil they can also stabilise the animal’s intestinal flora to improve feed efficiency (5% to 15% weight gains have been reported in cattle, pigs and poultry).

4.Sodium lignosulfonate are similar, buffering agents in the soil they can also offer a protective mechanism in the animal where they are able to form a protective film on the mucous lining of the gastro-intestinal tract. This film also helps to prevent excessive losses of water via the intestine.

5.Sodium Lignosulfonatecan also be used as concrete water-reducing agent, oil drilling mud dispersant, printing and dyeing and so on.
