Main Uses of Sodium Lignosulphonate

The sodium lignosulphonate is one of the very most common water reducing admixtures, but it can be used in multiple areas and industries. It is really a yellow-coloured, water-soluble powder and an anionic surfactant. This chemical is produced when wood pulp reacts with sulfite and sulfur dichloride aqueous solution. Listed here are the numerous uses of sodium lignosulphonate.

Main Uses of Sodium Lignosulphonate

(1) Used As Water Reducing Admixture

Sodium lignosulphonate is used as a concrete water reducing admixture in several construction projects. Additionally, it acts as a low-air retarding agent. It includes a dispersion and adsorption influence on the concrete and has the capacity to enhance numerous physical properties of the cement.

This chemical agent can decrease the usage of water by around 13%. In addition, it enhances the concrete's workability and decreases the hydration heat during the initial cement hydration stage. Sodium lignosulphonate can be used with the pumping agent, antifreeze, retarder, and early strength agent.

(2) In Agriculture

The sodium lignosulphonate in agriculture is used for multiple reasons. The most typical usage with this powder would be to improve the fertility of the soil and regulate its pH level. The pH range for plants should ideally be between 5.5 and 7. Lignins comprise numerous active groups that gradually degrade to humus.

This humus directly balances the soil's pH level, making it optimum for the growth of plants. Additionally it helps in slowly releasing and stabilizing the storage of nitrogen.

(3) As An Additive

This chemical compound may be used as an additive in the coal water slurry. Adding sodium lignosulphonate in the coal water slurry preparation helps in increasing the mill output, enhancing its concentration, decreasing the pulping's power consumption, and maintaining the conventional pulping system state.

During the gasification process, the coal and oxygen consumption reduces and the cold gas efficiency increases. Moreover, the coal water slurry's viscosity reduces, and its fluidity and stability reach a certain degree.

(4) As Body Reinforcing Agent

It can be used as a human body reinforcing agent in ceramic and refractories. For instance, through the manufacturing procedure for massive refractory bricks, floor tiles, and walls, sodium lignosulphonate tends to make the solid body's raw material particles stick together. In addition, it increases the potency of the dry billet by a lot more than 20%.

(5) In Pesticide Processing and Dye Industry

Sodium lignosulphonate can be used as dispersants and fillers in the dye industry. It will help boost the dyes'color power, make the colors more uniform, and reduce the dye grinding time.

It is also used as a suspending, dispersant, and filler agent in pesticide processing by enhancing the wettability and suspension rate of the wettable powder.

(5) In Carbon Black

Lignosulfonate is used as a binder in pyrolysis carbon black. In addition it enhances the strength of the pellets using solid type interactions between charged acid groups at a floor play. These interactions may result in stronger pellets. However, it might also result in some issues if the pyrolysis carbon black and surface morphology aren't compatible.

(6) In Drilling

Sodium lignosulphonate can also be used as a viscosity reducer and diluting dispersant in the drilling. Thus, it helps increase the crude oil transportation fluidity and decreases the usage of energy.

It is also found in petroleum products as a paraffin inhibitor, paraffin removing agent, emulsifying viscosity reducer, antistatic agent, antirust agent, high alkaline additive, dispersant, and a cleanup agent.

In addition to the above several uses, sodium lignosulphonate has many other uses. Please click on this page link https://kingsunconcreteadmixtures.com/sodium-lignosulfonate/  for more information.
