Sodium Lignosulfonate CAS 8061-51-6

Sodium lignosulfonate (CAS:8061-51-6) is an important surfactant.

Its main applications including:

1. Asphalt emulsifier

2. Grinding aids for cement production
3. Adhesives for casting and sand molds
4. Concrete additives
5. Scale removal agents and water quality stabilizers for boilers
6. Can be used as geological, oilfield, wellbore consolidation, and water-blocking agents for oil extraction, tertiary oil recovery additives in oil fields
7. Emulsifying dispersants
8. Sand prevention and fixation agents
9. Used in electroplating electrolysis to achieve uniform coating without dendritic patterns
10. As tanning aids in the leather industry
11. Used as flotation agents in mineral processing and bonding agents for mineral powder smelting
12. Coal briquette binder, water coal slurry additive
13. Slow-release nitrogen fertilizer agents, slow-release compound fertilizer improvement additives
14. Phosphate fertilizer production, slurry water reducer
15. Dyeing active agents, disperse dyes, filler for filling agents, diluent
16. Used as anti-shrinkage agents for lead-acid batteries and alkaline batteries cathodes

17. Fire-resistant materials, ceramic products dispersion, bonding, water-reducing and reinforcing agents

1. Store tightly sealed in cool, dry, well-ventilated areas below 25°C to prevent moisture absorption and caking of the brown powder.
2. Protect from direct sunlight and extreme temperatures to avoid oxidation and reduced dispersing performance.
3. Store separately from strong oxidants, concentrated acids and incompatible organic solvents; use plastic or stainless steel containers to avoid corrosion.

1. Avoid long-term inhalation of dust and prolonged skin contact; wear dust masks, chemical-resistant gloves and safety goggles during operation.
2. Do not ingest; rinse eyes and contaminated skin thoroughly with plenty of running water for at least 15 minutes in case of accidental exposure.
3. Dispose of waste solids and aqueous solutions in accordance with local environmental regulations for biodegradable polymer chemicals; avoid direct discharge into water bodies.

1. Natural anionic polymer from paper pulping by-products, biodegradable and cost-effective for green industrial applications.
2. Excellent water solubility and dispersing capacity; effectively stabilizes suspensions, reduces viscosity and prevents particle aggregation.
3. Versatile binding, chelating and water-reducing properties that work reliably across a wide pH range.
