Sodium lignosulphonate  is a kind of natural anionic surfactant of high molecular polymer, which is rich in sulfo group and carboxyl and has better water-solubility, surfactivity and dispersion force, made by a process of filtration, inspissation, chemical modification and spray drying with woord as raw material. Sodium lignosulphonate is widely used in various concrete projects, such as the prilling of concrete admixture, intensifer, suspending agent, dispersant, bulking agent, stabilizing agent, breeze, fertilizer, feedstuff, and foundry of sand mould, etc. 



Sodium Lignosulphonate  mainly usage is as the follows:

1. Sodium lignosulphonate used In the field of concrete additives, the sodium lignosulphonate series products can be applied as common water reducing admixture and built material of series multifunction high-performance water reducing admixtures. The products can be directly adopted as additive in the concrete .Moreover, they also can be compounded with such high-performance water reducing admixtures as naphthalene series and melamine series etc. And, they are also ideal materials for series retarding agents and pumping agents etc.

2. Sodium Lignosulphonate in Ceramic for ceramic products, can reduce the carbon content to increase green strength and reduce the amount of plastic clay, mud flows and good to improve the yield 70-90%, sintering speed reduction from 70 minutes to 40 minutes.

3. The sodium lignosulphonate series products can be adopted as the adhesives in the briquetting procedure in the vertical retort zinc smelters.

4. The sodium lignosulphonate series products can be used as embryo reinforcing agents in the fields of pottery and porcelain and refractory materials. They can increase the fluidity of the slurry and thus to improve the strength of the embryo.

5. In the field of water-coal paste, the sodium lignosulphonate series products can be adopted as the main compound materials.

6. In agriculture, the sodium lignosulphonate series products can be applied as the dispersant agents of pesticides and pelleting adhesives of fertilizers and feedstuffs.
