lignodispers-5L

PROPERTIES

Dispersants are widely used for suspending colloidal particles in cosmetics, paints, pharmaceuticals, drilling mud, cement, and ceramic applications.

LignoAdvances’ dispersants function as dispersing agents by adsorbing at the surface of the suspended particles and thereby provide a protective layer that hinder particle attraction. Our lignin-based dispersants increase the surface charge density of particles, which enhances repulsion force development between particles and stabilizes them in suspensions. They improve the hydrophilicity of particles and thus facilitate the interaction of water molecules and hydrated particles, thus reducing the hydrophobic/hydrophobic interaction developed between particles to prevent their agglomeration.

Our Lignodispers are polymeric dispersing agents with the function of controlling the interaction between fine particles, often solids, suspended in a second medium, often water.

Benefits:

• Lignin-based organic polymers to substitute synthetic dispersants
• Water soluble polymers which can be tailor made to your specific experimental operation
• As anionic polyelectrolyte polymers, our products are prone to adsorb onto a wide range of particle substrates possessing optimum charge density and solubility.
• Optimal dispersing agents for industrial wastewaters, clay suspensions and fertilizer productions
• Lignodispers with various water solubility, charge densities and molecular weights can be selected depending on the use, purpose and conditions.
• Improved control for dispersion and suspension concentrates
• Improved particle suspension in solution
• Improved the workability of concrete mixture and improved engineering quality
• Improved operation performance and have good effects such as reducing water, strengthening and preventing cracking
• Stable under extreme pH fluctuations.
• Function effectively in saline systems

Our specialized dispersants have a wide range of applications in:

• Dye removal
• The mining industry (ore suspensions)
• Coal-water slurry
• Pesticide formulations
• Ceramic suspensions and cement admixture
• Oil well dispersants
• Suspensions (gypsum pastes, titanium oxide particles, dimethomorph suspension)
