Sulfonated Lignite
Catalog NO.: AIMRSE-CHM-ADD-055 Manufacturer PN: CHM-LIG-SUL
• Temperature resistance up to 200°C; assists in forming a thin and tough mud cake; multi-functional; inexpensive product with high cost-effectiveness.
High-temperature loss control agent, high-temperature viscosity reducer, salt-resistant, calcium contamination resistant.
This product is a highly sulfonated lignite polymer designed for high-salinity brine systems. It functions as a high-temperature loss control agent and viscosity reducer, with a temperature tolerance of 200°C. It is suitable for brine systems containing NaCl, KCl, CaCl₂, MgCl₂, and other salts. This highly sulfonated product is suitable for high-salinity water-based systems. In contrast, lignin sulfonates or oxidized lignite products exhibit poor salt tolerance. Lignite or lignin products require caustic soda to achieve water solubility, whereas this product dissolves in water without caustic soda.
