Potassium lignosulfonate is a yellow powder solid which is easily dissolved in water. It is a macromolecular electrolyte with a molecular weight of 1,000-10,000. The dispersion of 10,000-40,000 is particularly effective. It has branched and cross-linked molecular structure, is a high quality cement grinding agent, after a lot of experiments and practice, has been widely used in cement plant.

Test Item Standard
Lignin content ≥55%
Water insoluble matter ≤1.0%
Moisture ≤3%
Reduzate ≤15%

1. Used as water reducer for concrete: adding 0.25 ~ 0.3% of the weight of cement can reduce water consumption by more than 10 ~ 14%, improve the workability of concrete and improve the quality of engineering. Summer use, can restrain slump loss, generally with high – efficiency water reducer compound use.

2. Used as binder: in smelting industry, potassium lignosulfonate is mixed with mineral powder to make mineral powder balls, which are dried and put into the kiln to greatly improve the recovery rate of smelting.

3, refractory materials: when manufacturing refractory bricks and tiles, using potassium lignosulfonate as dispersant and binder, can significantly improve the performance of the operation, and has a good effect of reducing water, strengthening, preventing cracking.

4. Ceramics: calcium lignosulfonate is used in ceramic products, which can reduce the carbon content and increase the strength of the blank, reduce the amount of plastic clay, improve the liquidity of the mud, improve the yield of 70-90%, and reduce the sintering speed from 70 minutes to 40 minutes.

5. Agriculture

A. improve the structure of soil mass, loosen the soil, improve the soil’s ability to retain fertilizer, adjust the pH value, reduce the content of heavy metals in the soil, and reduce the damage of salt ions to seeds and seedlings.

B. Nitrogen fixation, phosphorus dephosphorization, activated potassium, especially the synergistic effect of potassium fertilizer, which plays a role in increasing root and seedling strength, resisting stubble, disease resistance, and improving crop quality.

C. Strengthen the adhesion and fast absorption ability of plant roots, especially for the physiological diseases caused by the lack of trace elements.

6, as a feed binder, can improve the livestock and poultry like food, good particle strength, reduce the amount of feed powder, reduce the feed powder return rate, reduce the cost. Mold loss was reduced, production capacity increased by 10-20%, and the allowable dosage in feed in USA and Canada was 4.0%.

Potassium lignosulfonate can also be used in refining additives, casting, pesticide wettability powder processing, briquette press, mining, mineral processing agent, road, soil, dust control, tanning packing, carbon black granulation and other industries.
