Sodium lignosulfonate manufacturing process

 In the pulping process. Sodium carbonate or sodium hydroxide, calcium oxide, or a substituted calcium hydroxide. This method is relatively rare, because sodium carbonate or sodium hydroxide, is usually higher than the price of calcium oxide or calcium hydroxide. With pulp mill waste as a raw material,Sulfite or bisulfate process Bisulfite pulping of calcium contained […]

Sodium lignosulphonate

Sodium  lignosulphonate is mainly extracted from wood pulping and straw pulping.Most of Chinese manufacturer are using by products from paper factory. For paper factory they are using straw treated by NaOH to separate the cellulose for making papers then the rest is lignin and crude cellulose and sugar.Then they treated by sodium sulfite to regulate […]

Function of Lignosulfonate

Function of Lignosulfonate Ligno sulfonate ( sodium lignosulfonate ) pulping process of bamboo wood and straw extract, modification reaction was concentrated and spray- drying. Product is light yellow ( brown ) free flowing powder, soluble in water, chemically stable, long-term sealed storage without decomposition. Lignin series is a surfactant , can be modified , processing […]

Difference between lignin and lignosulfonate

Lignosulfonate is one of lignin derivatives. It is the source and lignin, chemical structures and physical properties are different. Lignosulfonate mainly from the sulfite pulping process resulting “black liquor”, separated from the black liquor extracted, mainly ligno sodium or calcium lignosulphonate. The three components of wood lignin itself (the other two are the cellulose and […]

Lignosulfonate application in leather tanning

Lignosulfonate application in leather tanning Lignosulfonate directly used in leather tanning effect is not good. Chemically modified lignosulfonate has a suitable distribution of the particle radius and bring a better soluble collagen protein reactive with a functional group reactive groups, can be used for leather tanning or retanning. Suitable modified lignosulfonate (re) tanning agent processed […]

Sodium Lignosulfonate Structurer

Sodium lignosulfonate is a natural polymer has three aromatic alcohols coniferyl alcohols, p-coumaryl alcohol, sinapyl alcohol, coniferyl alcohols is the principla. It has a strong dispersion capacity, due to the molecular weight and the type of functional group with varying degrees of dispersion capability.Also is a natural surfactant. Sodium lignosulfonate has strong cation exchange capability, […]

Function of Sodium Ligonosulfonate

Sodium lignosulfonate is a natural polymer having a strong dispersion, having a different degree of dispersion due to the molecular weight and the type of the functional group is a surface active substance can be adsorbed on a variety of solid on the surface of the particle, the metal ion exchange effect, and also because […]

About Lignosulfonate

Lignosulfonates are when traded a brown amorphous powder. They have no odour and they are not hygroscopic. They form colloidal solutions or dispersions with water but are not soluble in organic solvents. Lignosulfonates are biopolymers; they are salts of lignosulfonic acid that has been formed when pulp is manufactured by the sulphite method. The lignosulfonates […]

What is lignosulfonate

what is lignosulfonate Lignosulphonate, or lignosulfonate, or sulfonated lignin, (CAS No. 8061-51-6) are water-soluble anionic polyelectrolyte polymers: they are byproducts from the production of wood pulp using sulfite pulping. Most delignification in sulfite pulping involves acidic cleavage of ether bonds, which connect many of the constituents of lignin. Sodium lignosulphonate or calcium lignosulphonate have very […]
