Calcium Lignosulfonate Manufacturing Process

Calcium lignosulfonate is obtained from soft wood processed in sulfite pulping method for producing paper. They small pieces of softwood is put into reaction tank to react with acidic calcium bisulfite solution for 5-6 hours under the temperature of 130 degree Centigrade. During the process the bisulfite ions reacted with native lignin to for sulfonated lignin, […]

Calcium lignosulfonate uses in concrete

Calcium lignosulfonate in concrete action and dosage – Stone Refractories I. Calcium lignosulfonate water reduction in concrete reinforced role Calcium lignosulfonate and sodium lignosulfonate reducing agent is a surface-active agent, added to the concrete, due to the orientation of hydrophobic groups adsorbed on the surface of cement particles, so that the cement with a negative […]

Caclium lignosulfonate used as water reducing agent in concrete

Caclium lignosulfonate used as water reducing agent in concrete Calcium lignosulfonate is extracted from the  wood and straw pulp after sulfite pulping processed by advanced production technology have made of brown powdery solid, highly soluble in water. It is a polymer electrolyte having a molecular weight from the 1,000-100000. 10000-40000 dispersion which is particularly effective, […]
