Calcium lignosulfonate

Calcium Lignosulfonate Description

Calcium lignosulfonate (CAS NO. 8061-52-7)is a lignosulfonate compound that contains calcium as a cation. It is derived from lignin, a natural polymer found in the cell walls of plants.

Key points about calcium lignosulfonate:

1. Chemical Composition: Calcium lignosulfonate is primarily composed of lignosulfonic acid salts derived from the sulfite pulping process. It consists of lignin molecules modified with sulfonate groups and calcium ions.
2. Solubility: Calcium lignosulfonate is soluble in water and forms a solution in which the calcium ions and lignosulfonate molecules are dispersed.
3. Physical Properties: Calcium lignosulfonate is typically a brown to dark brown powder or granules. The exact appearance may vary depending on the manufacturing process and the specific product grade.

Calcium Lignosulfonate Application

1. 1. Concrete Admixture: Calcium lignosulfonate is widely used as a concrete admixture to improve workability, reduce water content, enhance strength and durability, and control setting time. It acts as a water reducer and dispersant, allowing for better handling and performance of concrete.
   2. Soil Stabilization: Calcium lignosulfonate can be used for soil stabilization in construction projects. It helps in binding and stabilizing soil particles, improving soil strength, reducing erosion, and preventing soil movement.
   3. Dust Suppression: Calcium lignosulfonate is utilized as a dust suppressant to control and reduce airborne dust particles. It is commonly used in construction sites, mining operations, and agricultural activities to minimize dust pollution and improve air quality.
   4. Animal Feed Binder: Calcium lignosulfonate acts as a binder in animal feed pellets. It helps to improve pellet quality, prevent dustiness, and enhance feed durability, making it easier to handle and ensuring proper nutrient intake for livestock and poultry.
   5. Ceramic Additive: Calcium lignosulfonate can be used as an additive in ceramic formulations. It acts as a binder, dispersant, and plasticizer, improving the workability, shaping, and drying characteristics of ceramics.
   6. Dispersant: Calcium lignosulfonate is utilized as a dispersant in various industries, including paints, coatings, and ceramics. It helps to disperse and stabilize solid particles, pigments, and clays in liquid systems, promoting uniform distribution and preventing settling or agglomeration.
   7. Agriculture: Calcium lignosulfonate can be used in agriculture as a soil conditioner and plant growth enhancer. It helps improve soil structure, water retention, and nutrient availability, leading to enhanced plant growth and productivity.
   8. Textile Processing: Calcium lignosulfonate can be used in textile processing as a dispersant, leveling agent, and dyeing auxiliary. It aids in the dispersion and leveling of dyes, ensuring uniform coloration and improved dye penetration on textile fibers.
