Sodium Lignosulphonate is a natural polymer extracted from wood and made by sulfonation of lignin. As a green chemical, Sodium Lignosulfonate is widely used in construction, agriculture, chemical industry and other fields, especially in concrete admixtures.

 

 

 

 

Sodium Lignosulfonate (SLS) is a kind of organic polymer compound obtained from lignin (a natural polymer compound) after a series of chemical treatments such as sulfation and alkalization. It has good water solubility, divisibility and surface activity. It is an important additive in paper making, dye, pesticide and other industries.

 

Mainly has the following characteristics:

Sodium Lignosulfonate as a concrete admixture, mainly used as a water-reducing agent and dispersant.

Main performance is:

Improve concrete strength: through reducing water consumption, increase the compactness of concrete and strength.

Improve the construction performance: improve the fluidity and ease of concrete, reduce the drainage and segregation phenomenon.

Environmental protection: come from natural materials, non-toxic and harmless, in line with the requirements of green building.

Cost-effectiveness: low production cost, high cost performance, significantly reduce the construction cost.

 

2.Agricultural

Sodium Lignosulfonate acts as a soil conditioner and a fertilizer additive.

Mainly used:

Improve soil structure: improve soil permeability and water retention, promote the growth of plant root.

Improve the fertilizer utilization rate: as a fertilizer additive, it can effectively improve the absorption and utilization efficiency of fertilizer.

Environmental protection and safety: non-toxic and harmless, will not cause soil and environmental pollution.

Promoting plant growth: promote healthy growth of crops by improving soil and improving fertilizer efficiency.

Sodium Lignosulfonate used as a dispersant to improve the fluidity of the ceramic slurry.

The main function:

Improve the slurry fluidity: improve the molding performance of ceramics and refractory materials, reduce the molding defects.

Reduce energy consumption: improve production efficiency, reduce energy consumption, reduce production cost.

Improve product quality: ensure the uniformity and consistency of ceramic products and refractory materials, and improve the final quality of products.

 

4.Chemical industry

Sodium Lignosulfonate as a stabilizer, adhesive and filler, widely used in the production of chemical products.

The main performance:

High stability: as a stabilizer, can effectively improve the stability and storage life of chemical products.

Enhance adhesion: used as an adhesive to enhance the adhesion between chemical materials.

 

5.Pulling paper making

Sodium Lignosulfonate used as a dispersant and stabilizer in the papermaking process.

The main characteristic:

Improve the quality of pulp: improve the dispersion and uniformity of pulp, enhance the strength of paper.

Reduce energy consumption: improve production efficiency, reduce energy consumption, reduce production cost.

Environmental protection: non-toxic and harmless, in line with environmental protection requirements, reduce the impact on the environment.

 

6.Leather industry

Sodium Lignosulfonate used as a degreasing agent and a dye-dispersing agent in the leather industry.

Mainly used:

Improve the effect of fat: effectively remove the oil in leather, improve the quality of leather.

Enhance staining uniformity: as a dye dispersant, improve staining uniformity and color brightness.

Environmental protection and safety: non-toxic and harmless, in line with the environmental protection standards of the leather industry.

 

 

 

Strict implementation of the standards for national certification bodies

 

1. The incorporation of our company Sodium Lignosulfonate can ffectively reduce the water cement ratio of concrete, reduce the water consumption of concrete under the same fluidity, and improve the compactness and strength of concrete. Its water reduction rate can reach 9-11%, significantly better than other similar products.

2. Under the appropriate dosage, our company Sodium Lignosulfonate water reducing agent can improve the strength of concrete by 15-20% in 3 days, the strength of 7 days by 20-30%, the strength by 15-20% in 28 days, and the long-term strength has also increased. This characteristic gives concrete a higher carrying capacity and durability in engineering applications.

3. Sodium Lignosulfonate water-reducing agent can can increase the fluidity of concrete, making it easier to pump and construct, and improving construction efficiency. At the same time, it can also improve the workability of concrete, making it easier to mix and vibrate.

4. Under standard conditions, the concrete mixed with our company's Sodium Lignosulfonate can delay the initial setting time of the concrete by more than 3 hours, the final setting time by 3 hours, and the hydration heat peak by more than 5 hours compared to the benchmark concrete. This feature is beneficial for summer construction, transportation of commercial concrete, and large-scale concrete engineering.

5. Sodium Lignosulfonate has slight air entrainment, small and uniform bubble odor, which can effectively improve the impermeability, freeze-thaw resistance, and enhance the durability of concrete in harsh environments.

6. Sodium Lignosulfonate has no corrosive effect on steel bars and aggregates when added to concrete, ensuring the long-term stability and safety of concrete structures.
