Description

Lignosulfonic Acid Calcium-Magnesium Salt is a water-soluble, anionic polyelectrolyte derived from the sulfite pulping of wood. This versatile compound is valued for its excellent dispersing, binding, and complexing properties, making it a key additive in various industrial processes. It is primarily utilized in the construction, agriculture, and chemical manufacturing sectors for applications ranging from concrete admixtures to dust control and pellet binding.

Application

• Concrete Admixture: Acts as a water-reducing agent and plasticizer to improve workability and strength of concrete mixes.
• Agricultural Pellet Binder: Used as a natural binder in the production of fertilizer and animal feed pellets.
• Dispersing Agent: Effective for suspending solids in aqueous systems, used in ceramics, dyes, and pesticide formulations.
• Dust Suppressant: Applied on roads and mining sites to control airborne dust particles.
• Oil Well Drilling Mud Additive: Functions as a thinner and fluid loss control agent in drilling fluids.
• Industrial Binder: Serves as an adhesive in briquetting, foundry sands, and carbon black pellets.
