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.
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. This is used for construction, ceramics, mineral powder, chemical industry, textile industry (leather), Metallurgical industry, petroleumindustry, fire-retardantmaterials, rubber vulcanization, organic polymerization, also could used as animal feedadditives due to its antimicrobial and preservative properties.
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).
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.
Precautions:
Keep away from heat. Keep away from sources of ignition. Empty containers pose a fire risk, evaporate the residue under a fume hood. Ground all equipment containing material. Do not ingest. Do not breathe dust. If ingested, seek medical advice immediately and show the container or the label. Keep away from incompatibles such as oxidizing agents, acids.
Storage:
Keep container tightly closed. Keep container in a cool, well-ventilated area.Section
