Sodium Lignosulfonate
Sodium Lignosulphonate is yellow brown powder completely water soluble,is naturally anionic surfactant of high molecular polymer, rich in sulfo and carboxyl group and has better water-solubility, surf-activity and dispersion capacity.
Application & Uses
Sodium lignosulphonate is used in many industrial fields. As water reducer it is used because of small dosage, low air content, good workability. The product is a modified nature lignin product. It has light wooden smell, it is not poisonous, not harmful. This powder has a good moisture absorption ability, water solubility and high chemical stability. It has different levels of purity (according to sugars left in the product).
Dosage & Directions for Use
The product can be used as water-reducer in a concrete admixture. It can lower a water requirements, promote the workability of concrete, reduce formulation cost and so on. The product can be used with different cements and inert aggregates. This products improves a fluidity and keeps slump retention at low dosage 0.2-0.3% (dry-dry) according to the experiment of customer.
