Description

Lignosulfonicacid,Sodiumsaltoxidized is a chemically modified, water-soluble anionic polymer derived from lignin, a major component of wood. This oxidized sodium lignosulfonate is valued for its excellent dispersing, binding, and complexing properties, making it a versatile and sustainable additive. It is primarily utilized in industries such as construction, agriculture, and ceramics where effective particle dispersion and rheology control are critical for performance and cost-efficiency.

Application

• Concrete Admixtures: Acts as a highly effective water-reducing agent and plasticizer, improving workability and strength of concrete mixes.
• Ceramic & Refractory Production: Serves as a binder and deflocculant in clay bodies and castables, enhancing green strength and moldability.
• Agricultural Dispersants: Used in the formulation of wettable powders, suspension concentrates (SC), and granules to improve the dispersion of active ingredients.
• Oil Well Drilling Fluids: Functions as a thinner and dispersant in water-based muds to control rheology and fluid loss.
• Dye & Pigment Dispersions: Enhances the stability and color strength of dispersions in textile and paint industries.
• Pelletizing & Briquetting: Acts as a natural binder in the agglomeration of fine powders, such as mineral ores, coal dust, and animal feed.
• Lead-Acid Battery Plates: Used as an expander additive in negative plates to improve battery capacity and cycle life.
• Dust Control: Applied as a dust suppressant on roads and mining sites due to its binding and moisture-retention properties.

Quality Control

Our Lignosulfonicacid,Sodiumsaltoxidized is produced under a stringent quality management system. Each batch undergoes rigorous testing to ensure consistent performance in key parameters such as sulfonate content, degree of oxidation, and dispersing power. While this product is typically supplied to industrial grade specifications, we can provide material compliant with relevant industry standards for specific applications. Certificates of Analysis (COA) documenting batch-specific results are available upon request.

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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after initial use to prevent caking and maintain product integrity. Keep away from strong oxidizing agents.
