JF SODIUM LIGNOSULPHONATE POWDER (MN-2)
(Synonyms: Sodium Lignosulphonate, Lignosulfonic Acid Sodium Salt)

In nature, lignin always coexists with cellulose and hemicellulose to build the plant skeleton together. Lignin is classified into three types: hardwood, conifer and herb. Generally speaking, lignin is distributed regularly in plant cells, the concentration of lignin in the intercellular layer is the highest, the concentration in the inner layer of the secondary wall is the second, and the concentration in the inner cell is the least. As the third largest organic resource in nature, although lignin was used by humans thousands of years ago, it has not been widely exploited yet.
At present, the lignin produced by our company is obtained by filtering, sulfonating, concentrating and spray-drying the black liquor of plant mixed pulp. effect. Cement, and can improve various physical properties of concrete.

Na Lignin Separate extraction:

In general, the separation of lignin can be divided into two categories: one is to dissolve the components other than lignin in the plant body, and then filter to separate the insoluble lignin. A typical example is in the wood hydrolysis industry, cellulose Under the action of acid, it is hydrolyzed to glucose, and the lignin is separated as the residue of hydrolysis; the other is to dissolve the lignin in the plant body, separate other components, and then separate out the lignin.
The latter type of separation is common in the pulping process of papermaking, and is subdivided into two types of separation methods. The former is to use an acidic sulfite solution containing calcium, magnesium, sodium, and ammonia to heat and cook the broken wood at 130~140 °C, The original lignin is sulfonated into water-soluble lignosulfonate, and then treated with lime milk to precipitate lignin; The lignin is changed into alkaline lignin, the cellulose is filtered out, and the remaining solution is treated with acid to precipitate the lignin.

Sodium Lignosulfonate Main use:

1. Reinforcing agent: It plays the role of water reduction, plasticization and flocculation in the production of refractory materials and ceramic products. It can also be used in the foundry industry. As an auxiliary binder, it has strong cohesion and good disintegration.
2. Mineral powder binder: The smelting industry mixes mineral powder with it to make mineral powder balls, which are dried and fed into the kiln to improve the smelting recovery rate, and can also be used as a mineral processing agent.
3. Used as concrete water-reducing agent: when the mixing amount is 0.2%-0.3%, it can reduce the water consumption during concrete mixing by 10%-12%, reduce the water-cement ratio, save about 10% of cement, and improve the workability of concrete. Fluidity and permeability resistance, improve concrete strength and compactness, have early strength effect, shorten setting time, improve compressive strength, and reduce concrete slump loss.
4. Antiscalants and corrosion inhibitors:
Used in industrial containers and pipes, it can prevent scale and corrosion, and improve the service life of windows and pipes.
5. Coal water slurry dispersant:
It is used in thermal power plants and other enterprises that use coal-water slurry as a dispersant to improve the dispersing ability of coal, increase the calorific rate and utilization rate of coal combustion, greatly reduce the coal content in fly ash, and reduce bridging and knots. block, improve the life of the furnace body.
6. Others: This product can be used as chemical agent for tertiary oil recovery, oilfield drilling mud diluent, and for well sealing. In addition, it can also be used as asphalt emulsifier, feed binder, refining auxiliary, etc. It is also widely used in pesticide processing, briquette production, tanning leather filler, carbon black granulation and soil, dune, and powder control.
