Calcium Lignosulfonate(CF-5)

Short Description:

Calcium Lignosulfonate(CF-5) is a kind of natural anionic surface active agent

processed with sulfurous acid pulping waste through advanced production technology. It can work well with other chemicals and produce early strength agent, slow setting agent, antifreeze and pumping agent.

  • Model: CF-5
  • Chemical Formula: C20H24CaO10S2
  • CAS No.: 8061-52-7
  • Product Detail

    Calcium Lignosulfonate(CF-5)


    Calcium lignosulfonate is a multi-component high molecular polymer anionic surfactant. Its appearance is light yellow to dark brown powder with strong dispersibility, adhesion and chelating properties. Usually comes from the cooking waste liquid of sulfite pulping, which is made by spray drying. The product is a brick red free-flowing powder, easily soluble in water, chemically stable, and will not decompose in long-term sealed storage.


    Appearance Free flowing brown powder
    Solid content 93%
    Lignosulfonate content 45% – 60%
    pH 7.0 – 9.0
    Water content ≤5%
    Water insoluble matters 2%
    Reducing sugar 3%
    Calcium magnesium general quantity ≤1.0%


    1.  Used as a water reducing admixture for concrete: the mixing amount of the product is 0.25 to 0.3 percent of the weight of the cement, and it can reduce the water consumption by more than 10-14 percent, improve the workability of the concrete, and improve project quality. It can inhibit slump loss when used in simmer, and is usually compounded with superplasticizers.

    2.  Ceramic: When the calcium lignosulphonate is used for ceramic products, it reduces carbon content,   improves green strength, reduces the consumption of plastic clay, has good slurry fluidity, improves the rate of finished products by 70 to 90 percent, and reduces the sintering speed to 40 minutes from 70 minutes.

    3.  Others: The calcium lignosulphonate can also be used for refining additives, casting, processing of pesticide wettable powder, briquette pressing, mining, ore dressing agents for ore dressing industry, the control of roads, soil and dust, tanning fillers for leathermaking, carbon black granulation and so on.


    Packing: 25KG/bag, double-layered packaging with plastic inner and outer braid.

    Storage: Keep dry and ventilated storage links to avoid dampness and rainwater soaking.
