Description

Lignosulfonicacid,Ammoniumcalciumsalt is a water-soluble polyelectrolyte derived from the sulfite pulping process, valued for its excellent dispersing, binding, and complexing properties. This versatile chemical is crucial for enhancing performance and efficiency in various industrial formulations. It is primarily sought by manufacturers in the construction, agriculture, and chemical processing industries for its multifunctional capabilities.

Application

• Concrete Admixtures: Acts as a highly effective water-reducing agent and plasticizer, improving workability and strength of concrete mixes.
• Agricultural Dispersants: Used in pesticide and herbicide formulations to enhance the stability and dispersion of active ingredients.
• Oil Well Drilling Fluids: Serves as a deflocculant and viscosity modifier in drilling muds to control rheology and fluid loss.
• Dye & Pigment Dispersants: Improves the dispersion and color strength of dyes and pigments in textile and paint manufacturing.
• Pellet Binders: Functions as a natural binder in the production of animal feed pellets, ceramics, and ore briquettes.
• Dust Control Agents: Applied to roads and mining sites to suppress dust by binding fine particles.
• Industrial Cleaners: Enhances the cleaning efficiency of formulations by dispersing soil and preventing redeposition.

Quality Control

Our Lignosulfonicacid,Ammoniumcalciumsalt is produced under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Each lot is tested against key parameters including active content, pH, reducing sugars, and solubility. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at ambient 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.
