Description

Lignosulfonicacid,Ammoniummagnesiumsalt CAS NO 123175-37-1 is a water-soluble, anionic polyelectrolyte derived from lignin, a major component of wood. This versatile compound is valued for its excellent dispersing, binding, and chelating properties, making it a key functional additive in various industrial processes. It is primarily sought after by manufacturers in the construction, agriculture, and ceramics industries for its ability to modify rheology and improve product performance.

Application

• Concrete Admixtures: Acts as a highly effective water-reducing agent and plasticizer, improving workability and strength of concrete mixes.
• Ceramic Production: Serves as a binder and deflocculant in ceramic slips and bodies, enhancing green strength and forming properties.
• Agricultural Formulations: Used as a dispersing agent and carrier for pesticides, herbicides, and micronutrients, improving their stability and efficacy.
• Oil Well Drilling Fluids: Functions as a thinner and fluid loss control agent in water-based mud systems.
• Dye & Pigment Dispersions: Enhances the stability and color development of aqueous pigment and dye suspensions.
• Industrial Pelletizing: Acts as a natural, cost-effective binder in the agglomeration of fine powders like mineral ores, coal dust, and fertilizers.
• Dust Control: Applied as a dust suppressant on roads and mining sites due to its binding and moisture-retention characteristics.

Quality Control

Our Lignosulfonicacid,Ammoniummagnesiumsalt is produced under a stringent quality management system. Each batch undergoes rigorous testing for key parameters such as active content, pH, reducing sugars, and ash content to ensure consistent performance and reliability for your formulations. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance protocols.

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); the container must be kept tightly sealed after each use to prevent caking and degradation due to moisture absorption.
