Technical characteristics

Technical lignosulfonates - are nature water resistants sulfo derivants of lignin, nascent in time of sulphit method of delignification of the wood, i.e. are the sodium salts of lignosulfonate acids with the dirt of mineral and reducing substances. Interest to lignosulfonates is due to the high surface activity, what lets to use these additives in different branches of industry - petrolium, mineral, chemical, metallurgy, mixtures manufacture and concrete, foundry.
