The product is introduced:

Sodium lignosulphonate is a kind of natural high molecular polymer, with a very strong sense of dispersion, due to the molecular weight and functional groups and different with different degree of dispersion, is a kind of surface active substance, can adsorption in all kinds of solid particle surface, and can be made the metal ion exchange effect, but also because of its organizational structure are all kinds of active group, thus can produce condensation effect or and other compounds occur hydrogen bonding interaction. At present our company sodium lignosulphonate SH - 1, SH - 2, SH - 3 series products have been in the domestic and foreign chemical, construction, ceramics, powder metallurgy, chemicals, petroleum, carbon black, refractory materials, coal-water slurry dispersant etc widely spread and applied.
