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