From this perspective, sodium lignin sulfonate is widely used in various industries and promotes the development of various fields.

What is the chemical structure of Sodium Ligninsulphonate?

Sodium lignin sulfonate is also the form of sodium salt of lignin sulfonate. Lignin is the main component of plant cell wall and has a complex three-dimensional polymer structure.
Its chemical structure is roughly like this: it is based on phenylpropane structural units, and each unit is connected by ether bonds and carbon-carbon bonds. And lignin sulfonate, that is, based on the lignin structure, the sulfonic acid group (-SO 🥰 H) is chemically modified into it. In sodium lignin sulfonate, the hydrogen atom in the sulfonic acid group is replaced by sodium ion (Na 🥰).
This structure gives sodium lignin sulfonate some unique properties. The sulfonic acid group endows it with hydrophilicity and can dissolve and disperse well in water. And because of its high molecular weight and complex spatial structure, it can be used as a dispersant, emulsifier and stabilizer in many systems. The long chain of phenylpropane units maintained by ether bonds and carbon-carbon bonds endows it with certain flexibility and mechanical properties. At the same time, the presence of sodium ions also affects its ion exchange performance and reactivity in some systems. The chemical structure of sodium lignin sulfonate makes it widely used in many industrial fields, such as concrete admixtures, dye additives, and oil drilling additives.

What is the proportion of Sodium Ligninsulphonate used in different industries?

Sodium lignin sulfonate is used in various industries and has a wide range of use cases. In the construction field, it is often used as a concrete water reducer. In the past, in civil construction, if you want concrete to have good workability, you need to add more water, but this will damage its strength. There are sodium lignin sulfonates, which can reduce water and maintain workability, and increase concrete strength. They are indispensable in the construction of high-rise buildings, bridges and roads.
In the paper industry, it is also widely used. When making paper, the fibers are not easily dispersed, resulting in poor paper uniformity. Sodium lignin sulfonate can make the fibers evenly dispersed, the quality of paper can be improved, and the paper is smooth and strong.
Furthermore, in agriculture, it can be used as a slow-release agent for fertilizers. In ancient times, fertilization was easy to lose and the utilization rate was low. With this as a slow-release agent, fertilizer was released slowly, crops could be raised for a long time, and soil fertility could be maintained, which helped greatly in the prosperity of farmers and mulberries.
Oil extraction, also see its power. When drilling, mud performance has a great impact. Sodium lignin sulfonate can adjust mud rheology, prevent water loss, ensure smooth drilling operations, and is crucial in oil well drilling. All of this shows that sodium lignin sulfonate has unique and important functions in different industries.

Is the production process of Sodium Ligninsulphonate complicated?

The production process of sodium lignin sulfonate is not simple at present. This process involves quite a lot of steps, which are interlinked and indispensable.
First, the selection of raw materials is the key. Lignin is often used as the base, but its sources are diverse, and the quality of materials is different. Careful selection is required to ensure that the lignin has a good texture before laying a good foundation for the subsequent process.
The second rule is the step of sulfonation. This is the priority of giving the lignin sulfonate group. The reaction conditions are harsh, and the temperature, pressure, reaction time and the ratio of sulfonating agent must be precisely controlled. If the temperature is too high, it may cause a cluster of side reactions and the product is impure; if it is too low, the reaction will be slow and the efficiency will be low. The same is true for pressure. Improper pressure will also affect the reaction process. The length of the reaction time is also related to the quality of the product. If it is too long, it will be over-sulfonated, and if it is short, it will not be sulfonated enough.
Furthermore, separation and purification. After the reaction is completed, the impurities in the product are mixed. If you want to obtain pure sodium lignin sulfonate, you must perform separation and purification. This process is also not easy, and a variety of methods are often used, such as filtration, centrifugation, crystallization, etc., to remove impurities and improve the purity of the product. The drying process after
should not be underestimated. The degree of drying If it is too dry, the product is easy to pulverize, and if it is too wet, it is easy to agglomerate, which is not conducive to storage and application.
All these, the production process of sodium lignin sulfonate is challenging, and it requires fine operation and strict monitoring to produce high-quality products.

What is the market price range for Sodium Ligninsulphonate?

What I am asking you is to inquire about the market price range of sodium lignin sulfonate. Sodium lignin sulfonate has a wide range of uses and is used in construction, chemical industry and other fields. Its price is not constant and often varies depending on quality, origin, and market supply and demand.
In the past, the price per ton for low quality products may be hundreds of yuan, which is suitable for occasions with lower requirements. And those with better quality can reach thousands of yuan per ton. If viewed from the origin, the price of sodium lignin sulfonate produced in a place with abundant raw materials may be slightly cheaper.
As for the current market, if the supply is abundant and the demand is not strong, the price may drop; conversely, if the demand increases sharply and the supply tightens, the price will rise. Generally speaking, the market price range is within 1,000 yuan per ton, and the high can reach 3,000 to 4,000 yuan per ton. However, this is only an approximate number. The actual price shall be subject to the real-time market conditions.
