Description

Ammonium Lignin Sulfonate is a water-soluble anionic polyelectrolyte derived from the sulfite pulping process of wood. This versatile biopolymer is valued for its excellent dispersing, binding, and complexing properties, making it a cost-effective and environmentally friendly additive. It is widely utilized across industries such as construction, agriculture, ceramics, and oilfield services to improve product performance and process efficiency.

Application

• Concrete Admixtures: Acts as a highly effective water-reducing agent and plasticizer, improving workability and strength of concrete mixes.
• Oilfield Drilling Fluids: Serves as a deflocculant and fluid loss control agent in water-based mud systems, stabilizing clay particles.
• Agricultural Dispersants: Used in the formulation of wettable powders, suspension concentrates, and granules for pesticides and fertilizers to enhance dispersion and stability.
• Ceramics & Bricks: Functions as a binder and plasticizer in clay bodies, improving green strength and forming properties.
• Dye & Pigment Dispersant: Enhances the dispersion and stability of dyes and pigments in aqueous systems, preventing agglomeration.
• Dust Control Agent: Applied to roads and industrial sites to suppress airborne dust particles by binding them together.
• Lead-Acid Battery Expander: Used in the negative plate paste to improve battery capacity and cycle life.
• Pellet Binder: Acts as an organic binder in the agglomeration of fine ores, minerals, or animal feed.

Quality Control

Our Ammonium Lignin Sulfonate is manufactured under a strict quality management system to ensure batch-to-batch consistency and performance reliability. While specifications vary by application grade (e.g., construction, agriculture, industrial), all products are tested for key parameters such as sulfonate content, pH, reducing sugars, and ash content. A Certificate of Analysis (COA) detailing the specific results for your order is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent caking or absorption of atmospheric moisture. Keep away from strong oxidizing agents.
