Products Description
Sodium lignosulfonate in solid form appears as a yellow-brown free-flowing powder, exhibiting excellent diffusibility and good chemical stability in aqueous solutions. As a superior anionic surfactant, it can be used for the dispersion of dyes, pesticides, pigments, etc., enabling uniform dispersion of pigment particles and thus improving the quality of related products.

Application
Drilling fluid treatment agent
As a viscosity reducer and dispersant：It regulates the rheology of drilling fluids, prevents the agglomeration of clay particles, and maintains the fluidity and stability of drilling fluids.
Improving lubricity of drilling fluids：It reduces the friction between the drill string and the wellbore, effectively minimizing drill string wear and the risk of downhole accidents.
Drilling mud property regulator
Control of drilling fluid viscosity and yield point：In different geological conditions (such as high-temperature and high-salinity environments), it maintains the stability of drilling fluid rheological parameters to ensure the smooth progress of drilling operations.
Inhibition of clay hydration swelling：It prevents the swelling of clay minerals in the formation when exposed to water, avoids wellbore collapse caused by swelling, and enhances the stability of the wellbore structure.
