Calcium Lignosulfonate


Calcium lignosulphonate

Product Description:

Calcium lignosulfonate (Calcium Lignosulphonate)is a multicomponent polymer anionic surfactant, the appearance of a pale yellow to dark brown powder, slight aroma, molecular weight is generally 800 to 10000, with strong dispersion, bonding, chelation. Usually derived from an acid pulping (otherwise known as sulfite pulping) of the cooking liquid and spray-drying. Soluble in water but does not dissolve in any common organic solvents.

Also known as: 104782-63-0, calcium 3-(2-hydroxy-3-methoxyphenyl)-2-[2-methoxy-4-(3-sulfonatopropyl)phenoxy]propane-1-sulfonate.

1.Used as concrete water reducer:

The amount that doped into the cement from 0.25 to 0.3%, water consumption can be reduced more than 10 to 14, can improve the workability of concrete and project quality.used in summer could control slump loss , and generally mixed use with superplasticizer.

2. Used as binder:

Smelting industry, with a combination of calcium lignosulfonate and ore into powder ball , then put it into the kiln after drying, can greatly improve the smelting recovery.

3. Used as refractories:

Manufacture of the refractory bricks,with calcium lignosulfonate as dispersants and binders ,could  improve operate performance significantly.aslo can reduce the water consumption , enhance , prevent cracking and other good results.

4.Used  in ceramics industry:

Calcium lignosulfonate used for ceramic products, can reduce the carbon content and increased the green strength , reducing the amount of plastic clay , slurry have good liquidity , increase the rate of finished products form 70% to 90 % , Sintering rate was reduced from 70 minutes to 40 minutes.

5. Used as feed adhesive:

Make the livestock and poultry eat more. calcium lignosulfonate can also imporve particle strength,reduce the return rate of fodder powder, lower the cost of feeding. According to the experience in USA and Canada, they are using 4% content of calcium lignosulphonate in the feed binder, their production capacity can improve 10-20%.


Calcium lignosulfonate additive can be used for refining , foundry , pesticide wettable powder processing, briquette pressing, mining, beneficiation agent selected mining , roads , soil, dust control , leather tanning fillers, granulated carbon black and other aspects .
