Sodium lignosulfonate uses as water plasticizer in construction
Sodium lignosulfonate used as plasticizer in concrete will reduce the cost by 10-15%,the sodium lignosulfonate could assume 0.5-2% of the total mixture w/w,will increase the strength of concrete by 20-26%. Sodium Lignosulfonate plasticizer Functions as follows Improved strength and durability of the cured concrete Reduced formulation cost Increased workability of the concrete mix Sodium lignosulfonate uses…

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…

Lignosulfonate CAS and Property
CAS No Substance 8061-51-6 Sodium lignosulfonate 8061-52-7 Calcium lignosulfonate 8061-53-8 Ammonium lignosulfonate 8061-54-9 Magnesium lignosulfonate Lignosulfonates are when traded a brown amorphous powder. They have no odour and they are not hygroscopic. They form colloidal solutions or dispersions with water but are not soluble in organic solvents. Lignosulfonates are biopolymers; they are salts of lignosulfonic acid that has been formed…

Lignin
Lignin is a chemical compound, which is usually separated from the tree, which is a lot of plants and algae in the second layer is the main component of cell walls. 1819 De Candolle introduced the concept of lignin, this phrase from Latin lignum, meaning trees. In woody plants, the lignin is the world’s second…

lignin properties
Different pulping processes and lignin extraction method to obtain the main physical and chemical properties include the following: 1.Color of lignin Original lignin is a white or nearly colorless material. We see the color of lignin, in isolation, caused by the preparation process. With the separation of the different preparation methods, showing different shades. Acid…

How to extract lignin
Two method to extract lignin One is the plant body other than the components are dissolved out of lignin, lignin as an insoluble component separated by filtration; typical example of this approach is the acid hydrolysis of wood, the cellulose is hydrolyzed into glucose, the hydrolysis of lignin residues are separation. Available 65% to 72%…
