Frequently Asked Questions

What are the main application fields of Ligninesulfonic Acid Sodium Salt?

Ligninesulfonic Acid Sodium Salt has a wide range of uses and is used in many fields.
In the construction industry, this is an excellent concrete water reducer. It can effectively reduce the water consumption of concrete, improve its fluidity, make concrete smoother when pouring, and can enhance the strength of concrete, improve its durability, and make construction more stable and lasting.
It is also common in the paper industry. In the pulping process, it can help the dissolution and separation of lignin, improve the quality and yield of pulp. At the same time, it can also improve the physical properties of paper, such as enhancing the strength and flexibility of paper, making paper products better.
In the agricultural field, calcium lignin sulfonate can be used as a fertilizer additive. It can improve the solubility and stability of fertilizers, help crops better absorb nutrients, improve the utilization rate of fertilizers, and then promote the growth and development of crops and increase yield.
Furthermore, in the field of oil drilling, this substance can be used as a mud treatment agent. It can adjust the rheology of mud, control its filtration loss, ensure the smooth progress of the drilling process, and ensure the safety and efficiency of drilling work.
In the ceramic industry, calcium lignin sulfonate is also useful. It can be used as a green body enhancer to enhance the strength of ceramic green bodies, reduce damage during molding and drying, and improve the yield of ceramic products.

What is the role of Ligninesulfonic Acid Sodium Salt in concrete?

Calcium lignin sulfonate (Ligninesulfonic Acid Sodium Salt) plays a crucial role in clay. It can be used as a dispersant to disperse clay particles evenly. Clay particles are easy to agglomerate. After adding this substance, it can adsorb on the surface of the particles, impart the same charge to the particles, and use the force of charge repulsion to distribute the particles evenly, avoid agglomeration, and improve the stability of the clay dispersion system.
Furthermore, it can act as a water reducer. When clay is mixed with water, it can reduce the surface tension between clay particles and water, reduce the amount of water, and do not damage the plasticity and fluidity of the clay. In this way, it can not only save water resources, but also optimize the working performance of clay, such as in ceramic production and other processes that use clay as raw materials, making clay easier to form and process.
In addition, calcium lignin sulfonate also has a certain retarding effect. It will adsorb on the surface of cement particles, hinder the hydration reaction of cement, and delay the setting time. In the case of mixed use of clay and cement, such as in the concrete deployment of construction, if the proportion of clay is high, adding this substance can avoid excessive condensation, strive for sufficient construction time, and ensure the quality of construction.
In addition, it also helps the water retention of clay. It can absorb water molecules, form a hydration film, reduce water evaporation and loss, and maintain clay humidity. When constructing or storing clay-related materials in a dry environment, it can prevent the clay from drying out and maintain good performance.

How does Ligninesulfonic Acid Sodium Salt affect the stability of the product?

Lignin sulfonic acid, the reason for the qualitative influence of this product. Its molecules contain sulfonic acid groups, etc., which can affect the interfacial activity of the product. If the system needs good dispersibility, lignin sulfonic acid can be adsorbed on the surface of the grain due to its sulfonic acid group water, so that it can be repelled, avoid aggregation, and improve the qualitative dispersion.
However, its qualitative is also affected by environmental factors. For example, pH value, the degree of lignin sulfonic acid at different pH levels is high, which affects its role in the product. In an acidic environment, the sulfonic acid group is suppressed, and the dispersion performance may be reduced, resulting in the qualitative resistance of the product. And the degree of resistance also has an impact. At high temperature, the degree of resistance is changed, or the adsorption of lignin sulfonic acid on the surface of the grain is broken, which weakens the repulsion force and reduces the quality of the product.
Furthermore, the degree of lignin sulfonic acid is also low. The degree of resistance should be able to effectively disperse the grain and improve the quality of the product. If the degree of resistance is high, or the surface of the grain is adsorbed and the molecular interaction of the lignin sulfonic acid can promote the aggregation of the grain and reduce the quality of the product. In addition, the qualitative impact of the product of lignin sulfonic acid needs to be taken into account.

What is the production process of Ligninesulfonic Acid Sodium Salt?

The production process of lignin sulfonic acid is made from lignin-based and chemical-like materials. The process begins with wood or other plant raw materials rich in lignin. First, these raw materials are treated with specific cooking liquids, and most of them are cooked with sulfuric acid or sulfuric acid.
In the cooking method of sulfuric acid, the raw materials are mixed with sulfuric acid and cooking liquids in a high-temperature environment. In this way, the lignin is broken down, the carbohydrates are separated, and a sulfonic acid group is introduced to generate lignin sulfonic acid. The neutralization process is used to treat the oxidation and other substances, so that the lignin sulfonic acid is reduced to the lignin sulfonic acid.
The sulfuric acid cooking method is also commonly used. The raw material sulfuric acid cooking liquid is co-placed in the digester, and at high temperature, the lignin is cracked to form lignin sulfonic acid. At the same time, the neutralization step is taken to reduce the amount of lignin sulfonic acid.
To obtain the crude product of lignin sulfonic acid, it is still necessary to improve the quality. It is often used to remove insolubility by methods such as heat, heart, etc.; it is also used to steam and heat to increase its quality; or the method of crystals and dryness is used to create the best finished product. Depending on the application, the molecular weight and sulfonic acid content of the finished product can be adjusted to meet the needs of different processes, such as dispersion and bonding.

What are the advantages of Ligninesulfonic Acid Sodium Salt over other similar products?

Ligninesulfonic Acid Sodium Salt has many advantages over other similar products.
First, this product has good dispersibility. In many industrial processes, such as dye preparation, pesticide preparation, etc., dispersibility is crucial. Calcium lignin sulfonate can make the particles evenly dispersed in the medium, as if it can make the particles safe in their positions and not agglomerate. In this way, the stability and uniformity of the product can be greatly improved, resulting in better product quality and better effect.
Second, it has excellent water reduction performance. In the construction industry, in the preparation of concrete, adding calcium lignin sulfonate seems to build a clever bridge between cement and water, which can effectively reduce water consumption without compromising the strength of concrete. In this way, not only can the cost be reduced, but also the durability of the concrete can be enhanced, making the building stronger and more durable.
Third, calcium lignin sulfonate has a certain retarding effect. In the process of concrete pouring, this property is extremely critical. It can delay the hydration reaction of cement, just like giving the builder more time to carefully carve, so that the concrete can be solidified at the right time, ensuring the smooth progress of construction, avoiding the construction difficulties caused by premature solidification, and reducing the quality problems caused by hasty construction.
Fourth, this material has a wide range of sources and low cost. It is mostly derived from the waste of the paper industry and is obtained through rational processing. This not only realizes the reuse of resources, but also reduces production costs. Just like turning waste into treasure, it is of great significance in both economic and environmental protection.
Fifth, calcium lignin sulfonate also has good chemical stability. Under different environmental conditions, it can maintain its own structure and performance stability, and is not easily deteriorated by external factors. Like a calm person, in complex and changeable environments, it always adheres to its own quality and provides a solid guarantee for the stable performance of products.
