Lignin is a complex matter that forms approximately 20% of the wood composition. During the process of producing and manufacturing pulp of wood, an extra fluid is produced that serves as an implicit product containing a complex mixture of materials, including pellet and cellulose degradation products, pellet sulphonate products, various carbohydrates (sugars) and acids Free sulfrox or sulfates. Subsequent neutralization, sedimentation and fermentation processes create a spectrum of concrete lignosulfonate additives with different clarity and purity. The compounds are also used depending on a number of factors such as alkaline neutralization, molding process, degree of fermentation, and even the type and age of wood.
Additive Commercial Lignosulfonates used in additive formulas, mainly based on sodium or calcium with sugar content
