The use of sodium lignosulfonate, whether sodium lignosulfonate is acidic or basic

Sodium lignosulfonate (sodium lignosulfonate) is an extract from the bamboo pulping process, which is concentrated and modified and spray-dried. The product is a light yellow (brown) free-flowing powder, soluble in water, chemically stable, and does not decompose after long-term sealed storage. Lignin series products are a kind of surfactant, which can be modified and processed to produce multiple products, mainly used in resins, rubber, dyes, pesticides, ceramics, cement, asphalt, feed, water treatment, coal-water slurry, concrete, refractories, oilfield drilling, compound fertilizers, smelting, casting, adhesives.

Through experiments, it has been proved that lignosulfonate is very effective in preventing sand from soiling soil, and can also be used as a desert fixing sand agent. The main properties are: 1. Concrete superplasticizer:

It is a powdered low gas retarding superplasticizer, which is an anionic surfactant, which has adsorption and dispersion effects on cement and can improve various physical properties of concrete. Reduce water consumption by more than 13%, improve the workability of concrete, and can greatly reduce the heat of hydration in the initial stage of cement hydration, which can be compounded into early strength agent, retarder, antifreeze, pumping agent, etc., and the liquid admixture made of naphthalene high-efficiency superplasticizer is basically not precipitated. 2. Coal-water slurry additives:

In the process of preparing coal-water slurry, the addition of this product can improve the output of the high mill, maintain the normal condition of the pulping system, reduce the power consumption of pulping, increase the concentration of coal-water slurry, reduce oxygen consumption and coal consumption in the gasification process, improve the efficiency of cold gas, and reduce the viscosity of coal-water slurry and achieve certain stability and fluidity. 3. Refractory materials and ceramic body reinforcing agent: In the manufacturing process of large-scale wall and floor tiles and refractory bricks, the raw material particles of the green body can be firmly bonded, and the strength of the dry blank can be increased by more than 20%-60%.

4. Fillers and dispersants for dye industry and pesticide processing: when used as dispersants and fillers for vat dyes and disperse dyes, the color strength of the dyes can be increased, the coloring is more uniform, and the time of dye grinding can be shortened; It can be used as a filler, dispersant and suspension agent in pesticide processing, which greatly improves the suspension rate and wetting performance of wettable powder. 5. As a binder for powdery and granular materials:

It is used for pressing balls of iron ore powder, lead-zinc ore powder, pulverized coal and coke powder; pressing of cast iron and cast steel sand molds; extrusion molding of mud bricks, wall and floor tiles, etc.; In terms of pelletizing, good strength, good stability, and lubrication of molds can be obtained. 6. It is used as a dilution dispersant and viscosity reducer in drilling; Improved flow in conveying and reduced energy consumption. In petroleum products, it is used as a cleaning agent, dispersant, high alkaline additive, rust inhibitor, antistatic agent, emulsifying viscosity reducer, wax dewaxing agent, etc.

Sodium lignosulfonate is a type of lignosulfonate. Lignin is a natural polymer with the second highest content in nature after cellulose and chitin, which can produce about 6 1014t per year in the world, and it can strengthen the interaction between plant cellulose as a filling and binding substance, and it is also a component that must be removed for large-scale extraction and utilization of plant cellulose. Lignin is a high-molecular-weight polymer with a three-dimensional network spatial structure of polyphenol and silver connected by three basic structural units, namely guaiac wood-based, clear or lilac-based and p-hydroxyphenylpropane, in the form of C-C bonds and C-O-C bonds.

Pro, sodium petroleum sulfonate and sodium lignosulfonate are two common sulfonate compounds that have some differences in structure and application. 1,**: Sodium petroleum sulfonate is prepared by petroleum sulfonate extracted from petroleum, while sodium lignosulfonate is obtained by sulfonation reaction of lignin extracted from plant cellulose.

Difference Between Sodium Petroleum Sulfonate and Sodium Lignosulfonate.

Hello, <>

Pro, sodium petroleum sulfonate and sodium lignosulfonate deficit are two common sulfonate compounds that have some differences in structure and application. 1,**: Sodium petroleum sulfonate is prepared by petroleum sulfonate extracted from petroleum, while sodium lignosulfonate is obtained by the distribution of lignin extracted from plant cellulose and the sulfonation finger talk reaction.

2. Structure: Sodium petroleum sulfonate is mainly composed of sulfate in petroleum and organic compounds in petroleum (such as alkyl sulfonic acid). Sodium lignosulfonate is formed by the reaction of the hydroxyl group in the lignin molecule with the hidden sulfonic acid group.

3. Physical properties: sodium petroleum sulfonate is usually presented as a white solid, soluble in water. Sodium lignosulfonate is also a white solid, but its solubility is slightly worse than that of sodium petroleum sulfonate.

4. Calling for application: Due to its good surface activity properties, sodium petroleum sulfonate is often used as a detergent, emulsifier and balance lubricant. It can also be used in industrial fields such as textiles, papermaking, and oil fields.

Sodium lignosulfonate is mainly used as an additive in the paper industry, which can improve the wet strength of the pulp and the acid resistance.

Hello, <>

In general, there are some differences between sodium petroleum sulfonate and sodium lignosulfonate in terms of structure, physical properties and applications. They have different roles and uses in industrial production, imitation and application.

Summary. Sodium lignosulfonate is a surfactant that can play a role in the pellet production process. It can be used as a dispersant and thickener to help the particles disperse evenly and increase the viscosity of the particles, thereby improving the stability and fluidity of the particles.

In addition, sodium lignosulfonate also has certain emulsifying and solubilizing effects, which can help the particle components to be better dissolved and dispersed in the aqueous phase. Therefore, according to the specific pellet production process and requirements, sodium lignosulfonate can be used as an auxiliary agent to improve the quality and stability of the pellets. However, it should be noted that the dosage should be controlled well when using to avoid adverse effects caused by excessive use.

Fellow, I really didn't understand, I can be more specific.

Sodium lignosulfonate can be used as a particle enhancer, which can improve the physical properties of the particles, improve the hardness and stability of the particles. In addition, sodium lignosulfonate can also be used as a dispersant for granules, which can promote the uniform distribution of active ingredients in the granules and improve the efficacy of the granules. Therefore, sodium lignosulfonate has a certain effect on the production of pellets.

However, the specific use effect of the gesture needs to be evaluated and adjusted according to the specific granule formula and production process.
