Sodium Lignosulfonate

Description

Sodium Lignosulfonate is a industrial chemical, widely used in papermaking and related industrial fields. As a compound, extracted from lignin, it has a variety of functions and applications.

As a sulfonate, Sodium Lignosulfonate has good water solubility and surface activity. So, it plays an important role in the papermaking process. The pulping and bleaching processes in the paper industry are inseparable from it. It is an additive to bleach, helping to remove impurities and pigments from paper pulp. Thereby improving the whiteness and quality of paper. In addition, it is also a surfactant that improves the water resistance and tensile strength of paper, making it tougher and more durable.

In addition to the paper industry, Sodium Lignosulfonate also has some applications in other fields. For example, in the field of drilling, it is an additive in drilling fluids. It can increase the viscosity and stability of drilling fluid, effectively control formation pressure during drilling, and prevent well wall collapse.

In addition, Sodium Lignosulfonate is also a dispersant for dyes and pigments. Due to its good surface activity and dispersing properties, it can help disperse pigments evenly in the medium, thereby improving the stability and color saturation of dyes and pigments. Therefore, it also plays an important role in the dye industry and ink manufacturing.
