What is Calcium Lignosulphonate? Make the Best Use of the Same

Calcium lignosulfonate is a kind of natural anionic surfactant processed with sulfurous acid pulp residues through advanced production technology. This can work fine with other chemicals and create an early forte agent, slow setting agent, antifreeze, and pumping agent. It is widely used in various concrete projects such as preformed concrete, reinforced concrete and prestressed concrete, especially applicable for commercial concrete, antifreeze concrete, waterproof concrete, bulk concrete, pumped concrete, with high economic benefit.

What is lignosulfonate used for?

Lignosulfonates happen to be used to disperse dyes, pesticides, carbon black, and other insoluble liquids and solids into water. They happen to be used in tanning leather. They are also used to suppress dust on unpaved roads. 

Calcium Lignosulfonate Methods of Operation

  1. 0.2-0.5% of the amount of mixing in concrete (with cement weight), users can adjust the amount of mixing through testing;
  2. Can be used after mixing the liquid, can also be put with cement, add in the mixer to use at the same time as well, need to lengthen the time correctly;
  3. The result is more evident after mixing with a high-efficiency naphthalene department water reducing agent. The user can determine the appropriate dosage according to the result of the fixing of the variety of cement, the situation of the aggregates, the type of water reducing agent of the naphthalene department;

Main performance

1 、 Used as a water reducing agent for concrete: 0.25-0.3% of the cement content can reduce water consumption by more than 10-14%, improving concrete workability and project quality. It can be used in summer for suppressing slump loss and happens to be usually used in combination with superplasticizer.

2 、 Used as a mineral binder: In the foundry industry, calcium lignin sulfonate is mixed with mineral powder to make mineral powder balls, which are dried and placed in the furnace, which can improve the recovery rate of the casting.

3 、 Refractories: When making refractory bricks and tiles, the use of calcium lignin sulfonate as a dispersant and binder can significantly improve operational performance and has good effects of water reduction, reinforcement and crack prevention.

4 、 Ceramic: Calcium lignosulfonate is used in ceramic products, which can reduce carbon content, increase green strength, reduce plastic clay consumption, improve mud fluidity, improve performance by 70-90%, and reduce sintering speed from 70 minutes to 40 minutes.

5 、 Used as a feed binder, it can improve the preference of livestock and poultry, good particle resistance, reduce the amount of fine dust in the feed, reduce the return rate of dust, and reduce costs. Mold loss is reduced, production capacity is increased by 10-20%, and the allowable amount of feed in the United States and Canada is 4.0%.

6 、 Others: Calcium Lignosulphonate Malaysia can also be used in refining aids, smelting, pesticide wettable powder processing, briquette suppression, mining, mineral processing benefit agent, road, soil, dust control, filling of leather tanned leather, carbon black granulation and other aspects.

Numerous studies have shown that the main reason for the low fertiliser usage rate is because chemical fertilisers have poor physical and chemical qualities. In the case of heat decomposition in the soil caused by soil component fixation losses owing to surface runoff, erosion, and subsurface infiltration, common chemical fertilisers dissolve quickly, polluting the ecological environment.

Rich source of calcium lignosulfonate, slow degradation in soil, no toxin, no residue, can improve the overall fertility of the soil, making fertiliser more conducive to increasing production and lowering costs.

Slow-release fertilisers with slowly dissolved nitrogen, non-volatile, slow release, and difficult leaching efficiency can be made with calcium lignosulfonate. The effect of calcium lignosulfonate on urease activity, nitrification, and denitrification, to a degree, can minimise ammonia volatilization. 1.01 percent calcium lignosulfonate and 19.4 percent sulphur wrapped in slow-release urea are added to urea.
