The Process of sodium lignosulphonate
Sodium lignosulphonate is an organic compound obtained from lignin, a natural polymer found in woody plants. This polymer has the ability to bind to other plant matter and give them structural support. During the process of producing paper or wood products, lignin is separated from the pulp and is considered a waste material. However, sodium lignosulphonate is derived from this waste product and is used in a variety of industrial applications such as concrete admixtures, animal feed, and textile dyes.
The process of producing sodium lignosulphonate involves several steps. First, lignin is extracted from wood chips or sawdust by the use of chemicals such as sodium hydroxide and sodium sulfide. This results in a black liquid known as black liquor. The black liquor is filtered and purified to remove impurities before undergoing acidification to help overcome the sulfide odor. The acidification results in the formation of lignosulphonic acid.
To produce sodium lignosulphonate, lignosulphonic acid undergoes a neutralization reaction with sodium hydroxide. During this reaction, sodium ions replace some of the hydrogen ions of the acid, resulting in the formation of sodium lignosulphonate.
The final product is a brown powder or liquid with excellent dispersing and binding properties. It improves the workability and strength of concrete, acting as a water reducer. It also improves the efficiency of animal feed by binding to nutrients and facilitating their absorption. In the textile industry, it acts as a dye dispersant, improving dye uptake for more accurate coloring.
In conclusion, sodium lignosulphonate is a versatile organic compound derived from the waste stream produced during the process of producing paper and wood products. Its wide range of applications speaks to its important role as a sustainable solution for repurposing otherwise discarded materials.
How to use sodium lignosulphonate
Sodium lignosulphonate is a multifunctional organic compound that finds its use in a variety of applications. These applications include concrete, ceramics, animal feed, and insecticides, among others. In this article, we will discuss how to use sodium lignosulphonate in concrete as a plasticizer.
Sodium lignosulphonate is an effective plasticizer and water reducer for concrete, preventing segregation and improving workability. It is also used as a stabilitizer in aqueous solutions and in the pulp and paper industry to improve paper strength and reduce pulp bleaching time.
To use sodium lignosulphonate as a concrete plasticizer, it should be added to the mixing water before adding the cement. It can be added in an amount of 0.1-0.3% by weight of cement. The addition of sodium lignosulphonate should be followed by the immediate addition of cement. The mixing time should be extended by 1-3 minutes to ensure proper dispersion of the lignosulphonate in the cement.
When using sodium lignosulphonate as a plasticizer for concrete, its dosage depends on the desired properties of the resulting concrete. The ratio of concrete to water can be reduced by up to 10-15%. The use of sodium lignosulphonate will also enable faster and more efficient utilization of cement, a key component of concrete.
In conclusion, sodium lignosulphonate is a versatile organic compound that finds use in various applications, such as concrete plasticizers. Its effectiveness as a plasticizer is due to its ability to reduce water content and improve the flow properties of concrete. Its dosage depends on the desired properties of the resulting concrete and can be added in an amount of 0.1-0.3% by weight of cement. With the correct use, sodium lignosulphonate can lead to better workability and strength of concrete structures.
