Chemical Property
Calcium lignosulfonate is a brownish yellow powder with good water solubility and a loose capacity of about 0.35 grams per cubic centimeter. It is an anionic surfactant, non-toxic, and has a pungent odor. The calcium lignosulfonate dry powder can be made from the waste liquid of sulfite wood pulp as the raw material, neutralized by lime milk, bio fermented and sugar removed, evaporated and concentrated to a solid content of 50%, and then dried by spray.
Product Features
Calcium lignosulfonate is one of the lignin derivatives obtained in the pulp industry. Its molecular structure basically retains the structural characteristics of lignin, namely the phenylpropane unit structure and a large number of ether bond connecting structures, and a large number of sulfonate groups are also introduced on its side chains. Therefore, when subjected to heating treatment, some condensation reactions should occur between and within the molecules of calcium lignosulfonate. Obviously, studying its thermal behavior and understanding the changes in the chemical structure and corresponding physical properties of calcium lignosulfonate under heating conditions is essential for the application of calcium lignosulfonate itself and its derivatives. Application: Calcium lignosulfonate can be used as a dispersant, emulsifier, wetting agent, etc. It can be used for industrial detergents, pesticides, pesticides, herbicides, fungicides, brick and refractory materials, concrete, cement, coke and charcoal processing, dyes and pigments, casting, gypsum products, granulation processing, oil, electroplating bath, tanning, wax lotion, etc.
Calcium lignosulfonate has various characteristics and applications:
1. It has high chemical stability and water resistance, and can exist stably under high temperature and humidity conditions.
Secondly, calcium lignosulfonate can be compatible with other materials and mixed with resins, rubber, etc. to improve the mechanical properties and thermal stability of the material.
3. Calcium lignosulfonate also has certain fluorescence properties and can emit specific fluorescence under ultraviolet light irradiation. This makes it widely used in fields such as fluorescent labeling, biological microscopy, and fluorescent probes.
4. Calcium lignosulfonate can also be used as a wastewater treatment agent, with high adsorption performance, which can effectively remove heavy metal ions and organic pollutants from water.
