    What are the main uses of Sodium Lignosulphonate?
    Sodium+Lignosulphonate, the Chinese name is sodium lignin sulfonate, which has a wide range of uses. In the construction field, it is a key component of water reducing agent. In construction, when mixing concrete, adding this agent can make the cement particles disperse evenly, reduce water consumption, improve the workability of concrete, make it more smooth to pour, and enhance the strength of concrete, making the building structure more durable.
    In the chemical industry, it is often used as a dispersant. In the production process of pigments and dyes, the pigment particles can be evenly dispersed in the medium to avoid agglomeration, improve the coloring power and stability of the pigment, and make the dyeing effect better.
    It is also used in the paper industry. In the pulp manufacturing stage, it can help lignin to separate from cellulose, reduce cooking energy consumption, improve pulp yield, and improve the physical properties of paper, such as increasing the flexibility and strength of paper.
    Furthermore, in the agricultural field, it can be used as a pesticide dispersant and a slow-release agent. It can evenly disperse the active ingredients of pesticides in the water, enhance the spraying effect of pesticides, and realize the slow release of pesticides, prolong the efficacy, reduce the loss and waste of pesticides, and improve the control efficiency of crop diseases and pests.
    In the ceramic industry, it is used as a green body enhancer and a water reducer. It can improve the formability of the ceramic body, reduce the moisture of the body, reduce the defects in the drying and firing process, and improve the quality and yield of ceramic products.
    Sodium Lignosulphonate is widely used in which industries
    Sodium + Lignosulphonate is also known as sodium lignin sulfonate. This product is widely used in various industries.
    In the paper industry, it is quite useful. When pulping paper, sodium lignin sulfonate can be derived from lignin. It can be used as a dispersant to make the fibers evenly dispersed, the paper is better formed, and the paper quality is also improved. And it can be used as a cooking aid to help lignin dissolve, reduce cooking energy consumption, and increase pulping efficiency.
    In the concrete industry, it is also indispensable. As a water reducer, sodium lignin sulfonate can reduce the amount of concrete mixing water. In this case, the fluidity of concrete remains unchanged, but the strength can be improved; if the strength remains unchanged, the amount of cement can be reduced and the cost can be reduced. At the same time, it can also prolong the setting time of concrete, which is very conducive to construction operations during summer construction or mass concrete pouring.
    Furthermore, in the agricultural field, sodium lignin sulfonate can also be used. It can be used as a pesticide dispersant, so that the active ingredients of pesticides are evenly dispersed in the water, increasing the coverage and adhesion of pesticides, and improving the efficacy. And it can be used as a slow-release agent for fertilizers, delaying the release of nutrients from fertilizers, improving the utilization rate of fertilizers, and enabling crops to absorb nutrients for a long time.
    In addition, in the ceramic industry, sodium lignin sulfonate can be used as an additive. It can improve the plasticity and fluidity of ceramic mud, make it easier to form the green body, reduce the defects of the green body, and improve the quality of ceramic products.
    In summary, sodium lignin sulfonate is widely used in papermaking, concrete, agriculture, ceramics and other industries, and is of great significance to the production and product quality improvement of various industries.
    What are the characteristics of Sodium Lignosulphonate?
    Sodium Lignosulphonate is also the best of sulfonic acids. Its characteristics can be described.
    First of all, this compound has good dispersion properties. In the industrial field, such as dyes and raw materials, it can make the particles disperse uniformly, prevent them from aggregating and settling, and ensure that the product is uniform and the performance is determined. The work of this dispersion is such that the particles are in their respective positions and do not coalesce.
    Secondly, Sodium Lignosulphonate has a certain surface activity. It can reduce the surface strength of the liquid and increase the performance. In the manufacturing process, it can help the moisture to enter the wood, promote the dispersion of the wood, and improve the quality of the product. The effect of its surface activity seems to be able to build up the beam of communication and make the connection more efficient.
    Furthermore, this material has coagulation properties. In cement concrete, it can be extended to cement setting, which is beneficial to the construction and operation of concrete. The ability of coagulation, such as the setting of concrete, is pressed to stop, so that it can be completed in the process of solidification.
    And because of its low cost and rich source, it is cost-effective in engineering and production, and can be used for both practical and practical purposes.
    Sodium Lignosulphonate is produced
    The method of making lignin sulfonic acid has been known in ancient times, and it is now described.
    First take the raw materials of wood, often pine, wood and other good things. The small amount of its crumbling is put into the cooking kettle. With sulfuric acid and a small amount of acid cooking liquid, add steam to make the temperature in the kettle rise to 100% to 10 degrees, and the strength is also increased. This lignin cooking liquid is reactive, and it is dissolved in the liquid to form lignin sulfonic acid.
    After steaming, the contents of the cold kettle are cold. The obtained liquid contains lignin sulfonic acid and others. To obtain the best quality of lignin sulfonic acid, it is necessary to improve it step by step. You can use the precipitation method first, add the sinking method, and make the lignin sulfonic acid sink, and then divide it. In the method of washing, except for the remaining waste.
    Wash the waste, re-dissolve it in water, and treat it with lipids. The lipids adsorb the waste, and the xylem sulfonate is combined with the waste, to obtain the solution of xylem sulfonic acid.
    At the end, the solution is lost, and the water can be removed by steaming. When the temperature is appropriate, the crystals are cold, and then the dry, the finished product will be solidified by xylem sulfonic acid. Its uniform soil and suitable color can be used for general workmanship, such as concrete water, dye dispersion, etc., the effect is low.
    What are the precautions in the use of Sodium Lignosulphonate
    Sodium lignin sulfonate, when using, there are several things to pay attention to.
    The first thing to know is its physical properties. Sodium lignin sulfonate is hydrophilic, and has the ability to disperse and emulsify. When using it, its solubility must be carefully reviewed. Under different solvents and temperatures, its solution state is different. If the water temperature is too low, it may not dissolve well, so that its performance cannot be fully developed, and it must be fully soluble before it can play a good role.
    The importance of secondary and compatibility. When this agent is mixed with other substances, its compatibility must be checked. In case of high-valent metal ions, or raw precipitation, its effectiveness will be damaged. When used in combination with certain surfactants, either synergistic gain or antagonistic elimination, must be tested first to clarify its compatibility and ensure that it is correct.
    Furthermore, it is related to the degree of dosage. If the dosage is too small, the work of dispersion and emulsification is not enough; if the dosage is excessive, it will only increase the cost and may lead to side effects. The precise dosage must be determined according to actual needs and tested to achieve not only the effect but also avoid waste.
    It is advisable to keep it in a cool and dry place to prevent it from getting wet and agglomerating. If it gets wet, it will not only be inconvenient to use, but also cause quality changes and reduce its effectiveness.
    In short, the use of sodium lignin sulfonate in dissolution, compatibility, dosage, and storage should be handled with caution in order to obtain its benefits and avoid its harm.
