Lignosulfonate, a by-product of wood pulping, has proven to be a versatile chemical with a broad range of applications across various industries. In this comprehensive overview, we delve into the unique attributes of sodium lignosulfonate and its widespread use in building and construction, water reduction, soil stabilisation, ceramic applications, and pellet binding.
Lignosulfate Uses
Building and Construction
For decades, sodium lignosulfonate has been a cornerstone in the construction industry, known for its eco-friendly nature and stabilising features. At Bisley Company, we’ve proudly supplied lignosulfonates, partnering with Domsjö Fabriker to offer premium quality sodium lignosulfonate to admixture companies across Australia, Asia, New Zealand, and the Middle East.
One of the standout features of lignosulfonate is its water-reducing ability, a result of its surfactant properties. By releasing excess water between particles, sodium lignosulfonate improves concrete compactness and impermeability. Construction companies, drawn to its simple and cost-effective water-reducing results, have incorporated it into numerous domestic constructions.
Lignosulfate can also have a retarding effect on the setting time of cement which can be beneficial especially in warmer weather.
Soil Stabilisation
Engineers and agricultural experts increasingly turn to sodium lignosulfonate for soil stabilisation. Its ability to tightly coalesce soil particles enhances waterproofness, making it a go-to choice in road construction. Recent tests on silty soils demonstrated improved wet-dry resistance and enhanced bonding between soil particles, ultimately leading to reduced road construction and maintenance costs.
Ceramic Applications
Lignosulfonate’s molecular adaptability allows for its use in enhancing the mechanical strength of ceramics. From reducing mudflow and improving adhesive properties to curbing shrinkage and serving as a lubricant in the extrusion or pressing stage, sodium lignosulfonate makes ceramic production more cost-effective and durable.
Pellet Binding
Lignosulfonates for diverse pellet binding applications. Whether incorporated into animal feeds for improved pellet quality, used in carbon black binding for heightened pellet strength, or applied in coal and coke refining to convert powder into manageable pellets, sodium lignosulfonate stands out as a cost-effective and efficient option.
The Bisley Advantage
Bisley & Company has been selling sodium lignosulfonate for over 30 years with a strategic partnership with Domsjö Fabriker for Asia, Oceania, and the Middle East regions. Domsjö is the second largest producer of sustainably produced lignin powder in the world. The bioenergy generated by the manufacturing process is used internally and makes them virtually independent of fossil energy sources. They are the only company in the world to have a closed loop bleaching process with zero emissions. For more information on Domsjö please visit their website.
