Calcium lignosulfonate Properties
About Calcium lignosulfonate Properties,need to make clear what is calcium lignosulfonate firstly.Calcium lignosulfonate (referred wood calcium) is a multi-component polymer anionic surfactant, the appearance of brown powdery substance, slight aroma, molecular weight is generally 800 to 10000, with a strong dispersion, bonding, chelation. Currently calcium lignosulfonate products have been widely used as a cement water…

Lignin
Lignin is a poylmer present in the structure of many polar groups, more particularly hydroxyl groups, lignin with strong intermolecular and intermolecular hydrogen bond energy, and therefore the original lignin insoluble in any solvent . Separation of lignin, because of reduced synthesis and degradation occurs, many physical properties change, the change in solubility resistance. Alkali…

WHAT IS LIGNOSULFONATE
Lignosulphonate, or lignosulfonate, or sulfonated lignin, (CAS No. 8061-51-6) are water-soluble anionic polyelectrolyte polymers: they are byproducts from the production of wood pulp using sulfite pulping. Most delignification in sulfite pulping involves acidic cleavage of ether bonds, which connect many of the constituents of lignin. Lignosulfonates are obtained from sulfite pulping processes wherein cellulose is extracted from wood…

Sodium Lignosulphonate Used In Dye Industry
Sodium lignosulphonate is a kind of anion surface-active agent made of sulphite whose main raw material is the northeast white pine, following the process of concentration, sugar-exclusion,displacement ,etc. It is used in dyestuffs industry mainly. This product has many kinds of different function , for instance viscidity control , colour adjusted etc., but main function is…

Sodium lignosulfonate Structure
Sodium lignosulfonate Structure is a natural polymer has three aromatic alcohols coniferyl alcohols, p-coumaryl alcohol, sinapyl alcohol, coniferyl alcohols is the principla. Three purified sodium lignosulfonates (SLs) with different molecular weights were prepared by ultrafiltration. The structural characteristics of SL and their effects on the properties of dye were investigated. When the molecular weight is…

Lignosulfonate used in oil drilling
Lignosulfonates could be used in oil drilling working as deflocculants, chemicals to prevent the coagulation of solids. Lignosulfonateand Modified lignosulfonate from wood pulp provides a chemical that is stable at the high temperatures – 150 to 250 degrees F– that occur in well bores during drilling. Clay minerals in drilling mud, such as bentonite, often…

Lignosulfonate Used in Dust Control
Lignosulfonate Used in Dust Control ,The overall impact on the environment from applying lignosulfonates to roads is negligible. They are safer to use for stabilization and dust control than any competing class of chemicals. The manufacture of lignin involves evaporation; the evaporation process drives off any volatile contaminants such as acetic acid. Corrosion and toxicity towards…
