Function

Sodium lignosulfonate has the nature of water soluble lyophilic colloid. Its particle brings with charge, a kind of surfactant, which can attach on the surface of solid particles. Because it has the form of strong acid salt, it can make ion exchange, Moreover, the lignin sulfonic acid group structure exists various radical polymerization, so it can produce internal polymerization or condensation with other compounds.

 

 

Usage:

1. 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 additives in the concrete. Moreover, they also can be compounded with such high-performance water reducing admixtures as naphthalene series and melamine series etc. In addition, they are also ideal materials for series retarding agents and pumping agents etc.

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

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