Brief Overview

The extract of the bamboo pulping process is sodium lignosulfonate (wood pulp), which is manufactured by concentrating, altering, spraying, and drying.

Sodium lignosulfonate is a free-flowing light yellow (brown) powder that dissolves easily in water. The product's chemical properties are stable, and long-term sealed storage cannot be degraded. The lignin series product is a type of surfactant that can be modified, processed, and compounded to make a wide range of goods.

 

Manufacturing Process

The sodium salt of lignosulfonate is sodium ligninsulfonate, an anionic surfactant that is a natural high molecular polymer. It has a high dispersing capacity and can be used to disperse solids in aqueous solutions.
media.


There are two categories of sodium lignosulfonate production methods in general:
1) exchanging ions with calcium lignosulfonate;
2) In the pulping process, substitute sodium carbonate or calcium hydroxide with calcium oxide or calcium hydroxide.
sodium hydroxide is a substance that contains sodium. Because of its rarity, this procedure is rarely used.

Construction

Sodium Lignosulfonate is a powdered water reduction agent with low air entraining. It's an anionic surface active material that has an adsorption and dispersion impact on cement and can improve a variety of concrete's physical qualities. Sodium lignosulfonate can cut water usage by more than 13%, enhance concrete workability, and significantly lower hydration heat during the early stages of cement hydration. It can be used as an early strength agent, a retarder, an antifreeze, or a pumping agent, among other things. The sodium lignosulfonate and naphthalene superplasticizer liquid combination scarcely precipitates.

 

Binder

Ball pressing of iron ore powder, lead zinc ore powder, pulverized coal and coke carbon powder, compaction of cast iron and cast iron sand mold, and extrusion molding of mud brick wall and floor tile may all be done with sodium lignosulfonate. Mineral materials can be balled to achieve high strength, stability, lubricating mold, and other desirable outcomes.

 

Ceramics Industry

Sodium lignosulfonate may help the raw material particles of the solid body firmly cling together, increasing the dry billet strength by more than 20% – 60% in the manufacturing process of large-scale wall and floor tiles and refractory bricks.

 

Dyes

Sodium lignosulfonate can be used as a dispersion and filler for vat dyes and disperse dyes, increasing the color power of the dyes, uniformizing the coloring, and reducing dye grinding time. In pesticide processing, sodium lignosulfonate can be employed as a filler, dispersion, and suspending agent, considerably improving the suspension rate and wettability of wettable powder.

 

Feed Additive

In the food business, sodium lignosulfonate is used as a de-foaming agent for paper manufacture and in adhesives for food-contact goods. It's employed in animal feeds because of its antibacterial and preservation characteristics.

 

Other Applications

It can be employed as a pigment dispersion agent, a pesticide filler and dispersant, a wax emulsion, and a tanning agent.
