8061-51-6 Sodium Lignosulfonate Powder For Concrete Additive Lignosulfonic Acid Superplasticizers

Sodium Lignosulphonate Powder 8061-51-6 For Concrete Additive Lignosulfonic Acid Superplasticizers

Na Ligno Sulfonate CAS 8068-05-1 Sodium Ligno Sulfonate Product Description:

Lignin is a biopolymer with a three-dimensional network structure formed by connecting 3 kinds of phenylpropane units through ether bonds and carbon-carbon bonds. It is rich in aromatic ring structures, aliphatic and aromatic hydroxyl groups, and active groups such as quinone groups.

JF SODIUM LIGNOSULPHONATE POWDER
(Synonyms: Sodium Lignosulphonate, Lignosulfonic Acid Sodium Salt)
JF SODIUM LIGNOSULPHONATE POWDER is produced from straw and wood mix pulp black liquor through filtration, sulfonation, concentration and spray drying, and is a powdery low air-entrained set retarding and water reducing admixture, belongs to an anionic surface active substance, has absorption and dispersion effect on the cement, and can improve various physical properties of the concrete.

Product Application:

(1) cement, concrete superplasticizer: lignosulfonate used as superplasticizer is one of the most widely used. Lignin sulfonate used as cement, concrete superplasticizer can not only greatly improve its fluidity and plasticity, but also can greatly reduce harmful pores, significantly enhance the compressive strength.
(2) dispersant, flocculant and corrosion and scale inhibitor: lignosulfonate is a good performance of anionic surface active
agent, can be used as dispersant, flocculant, etc.
(3) Oilfield chemicals: Lignosulfonate has a special molecular structure and is widely used in oilfield chemicals. It is often
used as surfactant for tertiary oil recovery, drilling fluid treatment agent and water plugging agent.
(4) Synthetic resin: since the 1990s, lignin is often used as a kind of synthetic polymer materials, resins and adhesives of a
basic renewable material.
(5) polymer materials: lignin and its derivatives can be mixed with polyvinyl chloride (PVC), polyethylene (PE), polyvinyl alcohol(PVA) and other olefin polymer materials, improve the stability, strength and anti-photolysis and other properties of the material. Liu Chunfang et al added lignosulfonate to rubber as a kind of rubber reinforcing agent, which can improve the mechanical properties of rubber. Li Haijiang et al. compounded hydrolyzed lignin and natural rubber to form an interpenetrating network structure, and then obtained a lignin-natural rubber compound by co-precipitation.
(6) Agricultural additives: sodium lignosulfonate can not only be used as a pesticide dispersant, but also as a wetting agent, complexing agent and fertilizer agent, widely used in all aspects of agriculture.
