Application

Descriptions:

• Sodium lignosulphonate is a yellow brown powder.

• Sodium Lignosulphonate is a kind of processed high molecular polymer, with a very strong of dispersion.

• Sodium lignosulphonate is anionic surfactant of high molecular polymer, rich in sulfo and carboxyl group.

• Sodium lignosulfonate is from alkaline paper-making black liquor through concentration, filtration and spray drying.

• Sodium lignosulphonate has good physical and chemical properties such as cohesiveness, dilution, dispersibility, adsorptivity, permeability, surface activity, surf-activity and dispersion capacity.

Uses:

• Sodium lignosulphonate can be used as a water reducing admixture for concrete and applicable for projects such as culverts, dikes, reservoirs, airports, expressways, etc.

• Sodium lignosulphonate can be used as a scale remover and a circulating water quality stabilizer on boilers.

• Sodium lignosulphonate can be used for electroplating and electrolysis, and can ensure that the coatings are uniform and have no tree-like patterns.

• Sodium lignosulphonate can be used as a tanning auxiliary in leather industry.

• Sodium lignosulphonate can be used as a flotation agent for ore dressing and an adhesive for mineral powder smelting.

• Sodium lignosulphonate can be used as coal water slurry additive.

• Sodium lignosulphonate can be used as long-acting slow-release nitrogen fertilizer agent, a modified additive for high-efficiency slow-release compound fertilizers

• Sodium lignosulphonate can be used as filler and a dispersant for vat dyes and disperse dyes, diluent for acid dyes and so on.

• Sodium lignosulphonate can be used for anodal anti-contraction agents of lead-acid storage batteries and alkaline storage batteries, and can improve the low-temperature urgent discharge and service life of the batteries.

• Sodium lignosulphonate series products can be applied as the dispersant agents of pesticides and pelleting adhesives of fertilizers and feedstuffs.
