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.
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.
The anionic polyacrylamide produced by Xinhuan Water Treatment can be used as coagulant aid, retention agent, sludge dewatering agent and coagulation precipitant. Because its molecular chain contains a certain number of polar groups, it can adsorb the suspended solid particles in water, make the bridge between particles or make the particles coalesce to form large flocs through charge neutralisation, so it can accelerate the settlement of the particles in the suspension, and it has the effect of accelerating the clarification of the solution and promoting the filtration, etc
