Calcium Lignosulfonate (CF-4)
Wood calcium, also known as calcium lignosulfonate, is a polymer anionic surfactant with multiple components. It appears as a light yellow to dark brown powder and has a mildly aromatic odor. It easily dissolves in water and exhibits good stability. Its molecular weight typically ranges from 800 to 10,000, providing it with strong dispersion, adhesion, and chelation properties. The versatility of calcium lignosulfonate is evident in its wide range of applications, including its use as a concrete superplasticizer, industrial detergent, pesticide and insecticide, herbicide, dye dispersant, coke and charcoal processing agent, petroleum industry additive, ceramic additive, and wax emulsion component.
Details of Calcium Lignosulfonate (CF-4)
Concrete water reducer: doped cement 0.25 to 0.3%, can reduce water consumption by 10 to 14, to improve the workability of concrete, improve project quality, could slump loss in summer use, generally complex to use with superplasticizer.
Mineral binders: melting industry, mixed with calcium lignosulfonate and slag into powder ball into the kiln dried, can greatly improve the smelting recovery.
Refractors: brick manufacturing refractories, the use of calcium lignosulfonate dispersant and binder, can significantly improve performances and reduce the water enhanced to prevent cracking and other good results
Ceramic additive: calcium lignosulfonate for ceramic products, can reduce the carbon content to increase the green strength, reduce the amount of plastic clay, mud flow, increase yield by 70-90%, the sintering rate reduced form 70 minutes to 40 minutes.

Calcium Lignosulfonate (CF-4) As Water Reducer
Calcium lignosulfonate water reducing agent is suitable for large volume concrete, large fluidity concrete, pumping concrete, commercial concrete and summer concrete construction and concrete with special requirements for retarding, cast-in-place concrete, pile concrete, manual excavation of concrete and underground mass concrete construction, generally with the use of high efficiency water reducing agent.
Safety And Operation Precautions of Calcium Lignosulfonate (CF-4)
Calcium Lignosulfonate Powder is a water soluble alkaline solution, direct and prolonged contact with eyes and skin may cause irritation. Wash the affected area of body with plenty of tap water immediately. If irritations persist for long time, please contact with doctor.
