Definition and Usage Area of Sodium Ligno Sulphonate
Sodium Ligno Sulphonate is a yellow brown powder is completely water soluble, naturally rich in anionic surfactants of high molecular weight polymers, sulfo and carbolsil group, and has better water solubility, surfactant activity and dispersion capacity. It can be used for construction, ceramics. Metallurgical industry, petroleum industry, fire retardant materials, rubber vulcanization, organic polymerization, mineral powder, chemical industry textile industry, which can also be used as animal feed additives due to its antimicrobial and protective properties.
- In plants, lignin in the cell wall provides the woody structure and durability of the plant, together with cellulose. It is not used in paper making, but is a by-product of paper production. It is abundant in 2nd and 3rd grade papers (duplicator papers, yellow papers such as straw paper). Lignin degrades over time, shortening the life of the paper.
- Many plant tissues contain, in addition to carbohydrates and foreign compounds, an amorphous and polymeric substance called lignin. The amount of lignin in mature tree tissue varies between 18% and 38%. Lignin is also found in grass and grass in different proportions.
- The biological role of lignin in living plants creates a tissue with excellent resistance and durability with cellulose and other carbohydrates of the cell wall. The chemical properties of lignin and the other two groups of natural polymers, carbohydrates and proteins, are quite different. They are easily and almost completely insoluble. They cannot be hydrolyzed to monomer units and lack the regular structure that is the most important feature of other natural polymers.
