Calcium Lignosulphonate: What It Is and How It’s Used


Calcium Lignosulphonate is a versatile and widely used additive in the Malaysian industrial sector. It is a natural and renewable polymer derived from wood pulping processes and has many applications in various industries, including construction, ceramics, agriculture, and chemical manufacturing. In this article, we will explore what calcium lignosulphonate is, how it’s used, and its benefits.

What is Calcium Lignosulphonate?

Calcium Lignosulphonate is a water-soluble polymer derived from lignin, which is a natural compound found in the cell walls of plants. It is produced during the pulping process of wood and is obtained by treating the black liquor with sulfur dioxide and a calcium compound. This process results in a highly purified, light-brown powder that is easily dispersible in water.

How is Calcium Lignosulphonate Used?

Calcium Lignosulphonate is used in various industries due to its unique properties. In the construction industry, it is used as a water reducer and a plasticizer in concrete and mortar. It improves the workability of the mix and increases its strength and durability. It is also used as a dispersant in gypsum wallboard and ceramic tiles, preventing agglomeration and improving their mechanical properties.

In agriculture, calcium lignosulphonate is used as a binder in animal feed pellets, improving their physical properties and reducing dust formation. It is also used as a chelating agent, increasing the availability of micronutrients in the soil and promoting plant growth. In chemical manufacturing, it is used as a dispersant and a stabilizer in emulsion polymerization, preventing coagulation and improving the quality of the final product.
