Description:

Sodium lignosulphonate is 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 from alkaline paper-making black liquor through concentration, filtration and spray drying, has good physical and chemical properties such as cohesiveness, dilution, dispersibility, adsorptivity, permeability, surface activity, chemical activity, bioactivity and so on.

Indicators:

Test Items	Speicifaction
Appearance	Yellow brown powder
Dry matter	>93%
Lignosulfonate	45-65%
pH	9-10
Water	<5%

Application:

1. Water-reducing agent

a. prefabricated or fresh concrete construction.

b. preparation of antifreezing, pump-deliverable water reducing agent.

c. preparation of different type of water reducing agent.

2. Used as fertilizer raw material. Sodium lignosulfonate is rich of many microelement and organic materials. It performs well as fertilizer raw materials.

3. Used as animal feed additives.

4. Used as ore binder: smelting industry, with sodium lignosulfonate mixed with slag, into powder ball into the kiln dried, can greatly improve the smelting recovery.

5. The refractory material: the manufacture of refractory brick, the use of sodium lignosulfonate dispersant and binder, can significantly improve performance and reduce the water, increased, to prevent cracking and other good results.

6. Ceramics: sodium lignin for ceramic products, can reduce the carbon content increased green strength, reduce the amount of plastic clay, mud, good liquidity, increase yield 70-90%, the sintering rate was reduced from 70 minutes to 40 minutes.

7. Leather tanning: By determining an appropriate base and degree of refining for the lignosulfonate, the characteristics of tanned skins can also be improved. The skins become softer and acquire a better feel.
