What are the physicochemical properties of Sodium Lignosulfonate?

Sodium + Lignosulfonate, that is, sodium lignin sulfonate. This is a compound with unique physical and chemical properties.
In terms of solubility, it is easily soluble in water. This property makes it easily dispersible in many aqueous systems, and it can be fused with water. It is like the water of fish, which provides convenience for its industrial application. It can be used as a dispersant in dyes, pigments and other industries, so that the pigment particles are evenly dispersed in the liquid phase without agglomeration and settlement.
In terms of stability, sodium lignin sulfonate is quite stable. At room temperature, it can be preserved for a long time without significant deterioration, just like an ancient object that has adhered to its essence after years. This stability ensures that its properties are not easily changed during storage and transportation, ensuring the consistency of product quality.
Its surface activity should not be underestimated. In the molecular structure of sodium lignin sulfonate, one end is a hydrophilic group and the other end is a lipophilic group. This structure gives it surface activity and can reduce the surface tension of the liquid, just like laying a smooth road on the liquid surface, so that substances that are not easy to mix can better contact and fuse with each other.

What are the precautions for using Sodium Lignosulfonate?

Sodium lignin sulfonate, when using, there are various matters to pay attention to.
First, it is related to storage. This agent should be stored in a dry, cool and ventilated place to prevent moisture. After covering it with moisture, it may cause changes in its properties and affect its performance. If it is in a humid place, it is easy to agglomerate and form agglomerates, which makes the dispersion poor, and it is difficult to use it to exert its due effect.
Second, about the dosage. The dosage needs to be accurately determined according to the specific use and system. If it is used too little, it may be difficult to achieve the expected effect. If it is used as a dispersant, if the amount is small, the dispersion effect will not be obvious, and the material will be easy to agglomerate; if it is used too much, it will not only increase the cost In some water-based paint systems, excessive use or abnormal viscosity of the paint can affect the construction performance.
Third, pay attention to compatibility. When using, be sure to consider its compatibility with other substances. If it is incompatible with certain surfactants or additives, it may lead to precipitation, flocculation and other phenomena. For example, when compounding pesticide formulations, improper compatibility with other additives will reduce the stability and efficacy of pesticides.
Fourth, the operating environment should not be ignored. During operation, it is advisable to maintain good ventilation, and operators should take appropriate protective measures, such as wearing gloves, masks, etc. Because it may be irritating to the skin and respiratory tract, poor protection and vulnerable to health.
In short, the use of sodium lignin sulfonate requires careful attention in terms of storage, dosage, compatibility, and operating environment in order to achieve good use results and ensure safety.
