Calcium Lignosulphonate

Description

Calcium Lignosulphonate is a multi component polymers anionic surface active agent, has a strong dispersion and bonding. From cooking waste liquid of acid pulping, usually by spray drying. It contains 30% above the reducing sugar, soluble in water, but insoluble in any ordinary organic solvents. Its PH value is about 3~11 in 1% of its water solution.


Standards Compliance

ASTM C 494, Type F; ASTM C 1017, GB8076-1997 and GB50119-2003.


Main Use & Advantages

1) As concrete water reducing agent: with 0.25~0.3% of weight of cement, water consumption can be reduced more than 10~14, improve the workability of concrete, improve the quality of engineering. Used in summer, it can inhibit the slump loss, and it generally used with high efficiency water reducing agent.

2) Used as mineral binder: in smelting industry, mixed with calcium lignosulphonate and breeze, to manufacture mineral powder ball, and then take it into kiln after dried. It can greatly improve the smelting recovery rate.

3) Refractory material: Using lignin calcium sulfonate as dispersant and adhesive then manufacturing refractory brick. And it can significantly improve the operating performance, reducing water, increase strength, preventing cracking etc.

4) Ceramics: Calcium Lignosulphonate for ceramic products, can reduce the carbon content and increase green strength, reduce the amount of plastic clay, good mud fluidity, increase the rate of finished products of 70~90% and reduce the sintering speed 70 minutes to 40 minutes.
