What are the application examples of Calcium Lignosulfonate in different industries?

Calcium lignin sulfonate has many wonderful uses in various industries. Here are some examples of its application.
In the construction industry, it can be used as a concrete water reducing agent. Ancient construction, building walls and foundations, and material deployment need to be exquisite. At present, calcium lignin sulfonate into concrete can reduce its mixing water consumption and maintain its workability. For example, in the construction of high-rise buildings and large buildings, this agent can make concrete have good fluidity. When pouring, it can evenly fill all parts of the formwork without damaging its strength. It is like injecting agility into concrete, making the building foundation more stable.
In the agricultural field, it can be used as a soil conditioner. In the past, farmers used to rule the field, often worried about soil compaction and unsustainable fertility. Calcium lignin sulfonate applied to the soil can change its structure, increase its ability to ventilate and permeate water, make the soil loose as cotton, conducive to deep roots and wide distribution of crops, and can retain water and fertilizer, just like creating a comfortable home for crops and helping them thrive.
It is also commonly used in the papermaking industry. In ancient times, papermaking was complicated, but today's papermaking, calcium lignin sulfonate can be used as a dispersant. When the pulp is prepared, the fibers can be evenly dispersed, resulting in paper with uniform texture, smooth surface, and suitable for writing and printing, just like giving the paper a delicate quality.
In the oil mining industry, it can be used as an additive for drilling mud. In the past, drilling often encountered the collapse of the well wall and the unstable performance of the mud. The addition of calcium lignin sulfonate to mud can increase its stability, reduce its filtration loss, make the well wall solid, ensure the smooth progress of drilling operations, and pave a smooth way for drilling.
And so on, the application of calcium lignin sulfonate in various industries is the key to improving efficiency and quality, and it is an additive that cannot be ignored.

What is the production process of Calcium Lignosulfonate?

The production process of calcium-lignin sulfonate is an important method in the chemical industry. Its initial raw material is often taken from the waste liquid of sulfite pulping, which is rich in lignin sulfonate.
The first step is pretreatment. The sulfite pulping waste liquid is aggregated, and the suspended impurities, such as unevaporated wood chips and fiber debris, are removed by sedimentation and filtration, so that the waste liquid can be preliminarily clarified.
The next step is separation and concentration. By means of evaporation and concentration, the concentration of lignin sulfonate in the waste liquid is increased. Due to the gradual loss of water during evaporation, the lignin sulfonate is enriched. Afterwards, the lignin sulfonate is separated from the concentrate by ion exchange or precipitation. For example, adding an appropriate amount of calcium salts, such as calcium chloride, allows lignin sulfonate ions to combine with calcium ions to form calcium-lignin sulfonate precipitation, which is then centrifuged or filtered to obtain a pure precipitation.
Another is the drying process. The separated calcium-lignin sulfonate is precipitated and dried at low temperature to remove residual moisture. The drying method can be selected from vacuum drying or spray drying. Vacuum drying can be carried out at a lower temperature to avoid its high temperature decomposition; spray drying is quite efficient and can quickly convert liquid materials into dry powder products.
At the end is packaging and quality inspection. The dried calcium lignin sulfonate products are inspected according to Quality Standards to observe their purity, particle size, moisture content and other indicators. Those who are qualified should be packaged with suitable packaging materials for sale and application. In this way, the production process of calcium lignin sulfonate is through pretreatment, separation and concentration, drying and quality inspection packaging processes.

What is the market price of Calcium Lignosulfonate?

Calcium lignin sulfonate, the market price is also, often due to the quality of the quality, the supply and demand of the market changes. Looking at the past, its price may range from hundreds to thousands of yuan per ton.
Those with high quality, the price is high. If it has high purity and good performance, it is beneficial for industrial uses, such as as dispersants, water reducers, etc., it can improve the quality and efficiency of industrial production, and its price is often high, or up to thousands of yuan per ton.
Those with lower quality, the price is low. Such or purity is not high, and there may be limitations in application, so the price is also low, or only a few hundred yuan per ton.
In addition, the supply and demand of the city is also the main reason for the price. If there are many people who want it, but there are few people who supply it, the price will rise; if the supply exceeds the demand, the price will fall. In the past, the industry was prosperous, and there were more people who needed it, and the price often went up; when the industry slowed down and the demand was small, the price also went down.
Basically speaking, the market price of calcium lignin sulfonate, if it is of high quality and the market is prosperous, the price per ton may be nearly 3,000 yuan or even higher; if the quality is flat and the supply is small, the price per ton may be around 1,000 yuan, or even hundreds of yuan. However, the market conditions change, and the price is also variable, when the real-time market conditions shall prevail.

What are the advantages of Calcium Lignosulfonate compared to other similar products?

Calcium lignin sulfonate has several advantages in various similar products.
Its main advantage is its outstanding dispersion performance. Just like the ancient good soldiers, it can make soldiers evenly distributed and their combat strength can be developed. Calcium lignin sulfonate in powder materials can also make the particles evenly dispersed without agglomeration. In this way, it can improve the fluidity and stability of the material. In processes such as concrete mixing, cement particles can be evenly dispersed in water, enhancing the workability of concrete, making it smoother to pour, and less prone to segregation.
Furthermore, it has the characteristics of slow condensation, which is like a steady march on the way, not rash. In concrete production, it can delay the hydration reaction of cement, just like letting the army that is eager to move forward take a break, so as to prolong the setting time of concrete. In high temperature environments or long-distance transportation, this feature is of great benefit, which can ensure that concrete maintains good working performance within a specified time, and will not prematurely set and affect the construction.
In addition, calcium lignin sulfonate has a wide range of sources and low cost. Just like an inexhaustible source of materials, this is a major item in large-scale production applications. Its raw materials are mostly taken from the waste liquid of the paper industry, which turns waste into treasure, which not only solves the problem of paper waste liquid treatment, but also reduces production costs. It is in line with the ancient "make the best use of everything" approach, which is really two birds with one stone.
And its environmental performance is good, environmentally friendly. In today's environmentally friendly world, it is like a gentleman who does not disturb the peace of heaven and earth. During use, it does not produce harmful emissions, does not pollute water and soil, and coexists harmoniously with the surrounding environment, contributing to the sustainable development of engineering construction.
