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.

Calcium linosulfonate(calcium lignosulphonate) is an amorphous yellow powder extracted from sulfite pulping of wood.The framework turned out to be three aromatic alcohols:coniferyl ,alcohol,p-counmaryl alcohol and sinapyl alcohol.Complete water soluble and  practically insoluble in organic solvent.

Also known as: 104782-63-0, calcium 3-(2-hydroxy-3-methoxyphenyl)-2-[2-methoxy-4-(3-sulfonatopropyl)phenoxy]propane-1-sulfonate, Caswell No. 146

  • As a concrete water reducer : doped cement volume 0.25 to 0.3% , water consumption can be reduced from 10 to 14 or more, to improve the workability of concrete , improve project quality. Summer use, could slump loss , are generally complex and superplasticizer used .
  • Used as a binder ore : smelting industry, the use of calcium lignosulfonate with powder mixed into powder ball into the kiln dried , can greatly improve the smelting recovery .
  • Refractories : Refractory brick manufacture , the use of calcium lignosulfonate dispersant and binder , can significantly improve performance , and reduce the water , enhance , prevent cracking and other good results.
  •  Ceramics: calcium lignosulfonate for ceramic products, can reduce the carbon content increased green strength , reducing the amount of plastic clay , mud, good liquidity , increase yield 70-90 % , sintering speed from 70 minutes down to 40 minutes .
  • The adhesive used as feed , livestock and poultry can be improved eating resistance, particle strength , and reduce the amount of feed powder , powder to reduce the anti-back ratio and reduce costs. The loss modulus decreased 10-20% increase in production capacity , the United States and Canada allow content in the feed was 4.0% .
  • Other: 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 .
