Sodium lignosulfonate is used as a defoamer in papermaking in the food industry and as an adhesive in articles that come in contact with food. It has antiseptic properties and is used as an ingredient in animal feed. It is also used in construction, ceramics, mineral powder, chemical industry, textile industry, metallurgical industry, petroleum industry, flame retardant materials, rubber vulcanization, organic polymerization. It is a pepsin inhibitor.
sodium lignosulfonate uses in construction
The applications of lignin and its modified products are mainly in the following aspects:
(1) Cement and concrete water reducer: Lignosulfonate is currently the most widely used water reducer. In 1935, successfully developed a water-reducing agent with lignosulfonate as the main component. Since then, mankind has begun the research on lignosulfonate water-reducing agent. The use of lignosulfonate as a water reducing agent for cement and concrete can not only greatly improve its fluidity and plasticity, but also greatly reduce harmful pores and significantly enhance compressive strength.
(2) Dispersant, flocculant and corrosion and scale inhibitor: Lignosulfonate is an anionic surfactant with excellent performance, which can be used as dispersant, flocculant, etc.
(3) Oilfield chemicals: Lignosulfonates have a special molecular structure and are widely used in oilfield chemicals. They are often used as tertiary oil recovery surfactants, drilling fluid treatment agents, and water shutoff agents.
(4) Synthetic resin: Since the 1990s, lignin has often been used as a basic renewable material for synthetic polymer materials, resins and adhesives.
(5) Polymer materials: Lignin and its derivatives can be blended with polyvinyl chloride (PVC), polyethylene (PE), polyvinyl alcohol (PVA) and other olefin polymer materials to improve the stability, strength and Anti-photolysis and other properties. Liu Chunfang and others added lignosulfonate to rubber as a rubber reinforcing agent, which can improve the mechanical properties of rubber. Li Haijiang and others compounded hydrolyzed lignin with natural rubber to form an interpenetrating network structure, and then prepared a lignin-natural rubber compound by co-precipitation.
(6) Agricultural additives: Sodium lignosulfonate can be used not only as a pesticide dispersant, but also as a wetting agent, complexing agent and fertilizer enhancer, and is widely used in all aspects of agriculture.
Sodium lignosulfonate It is produced by reed as raw material and produced by low pollution technology,sodium lignosulfonate is with good solubility, high surface activity and dispersing ability.It is a sulfonate derivative contents benzoic acid and carboxyl.It's adhesion, dispersion and chelation are widely used in various industries to improve its physical and chemical properties, save costs and improve efficiency. Mainly export for Concrete: Polycarboxylate superplasticizer is a new type of water reducing agent. The water reduction rate is generally around 20%, but it has high requirements for cement and sand of concrete.If the mud content in the sand is slightly larger, the polycarboxylate superplasticizer has a water reduction rate of 0.However, the technical team found that when using polycarboxylate superplasticizer's dosage is 6% of weight with sodium lignosulfonate's dosage 4%-6%,the water reduction rate will reach the most ideal water reducing ratio and the cost of concrete admixture is also the most economical.Because of the characteristics of calcium and magnesium ions in Sodium lignosulfonate, it is easy to occur precipitation and discoloration when mixed with polycarboxylate superplasticizer.
Applications: In Animal feed stuff Nutrition feed for Poultry, Layers, Cattle. Primarily used as a dairy cow feed supplement, the buffering capability of Natural Soda's pure and natural feed grade sodium bicarbonate helps stabilize rumen pH by reducing acidic conditions. Improves calcium absorption and eggshell quality of laying hens during peak production.

Applications; This grade is intended for general applications like chemical synthesis, dyes, leather, fire extinguishers, water treatment, plastic molding, flue gas treatment & in the drilling industry, sodium bicarbonate is used to chemically treat drilling mud when it becomes contaminated with calcium ions from cement or lime. It is NOT intended for applications, directly or indirectly, related to human consumption.
Sodium lignosulfonate is used for ceramic binder, cement water reducer, charcoal binder and grinding dust sag binder
White powder or tiny crystals, inodorous and salty, easily soluble in water, insoluble in alcohol, presenting slightly alkalinity, decomposed when heating. Decomposed slowly when exposed to moist air. Natural soda is firstly dissolved into solution (Na2CO3) and filtrated. The clear solution is then fed to carbonizing tower ; accordingly, CO2 is compressed and bubbled up from the bottom of the tower, After carbonization, the slurry will be flowed from the bottom and separated. Dried to the finished product. Usage: Used as food fermentation, detergent ingredient, carbondoxide foamer, pharmacy, leather, ore milling and metallurgy, detergent for wool, exiting usher and metal heat-treating, fiber and rubber industry, etc.
