Lignosulfonic acid

Описание

Lignosulfonic acid is an organic compound with a variety of industrial applications. It is a multi-component high molecular polymer, an anionic surfactant, with good water solubility and surface activity. It usually appears as a yellow (brown) or brown fine powder. And Lignosulfonic acid dry powder has strong adhesion when it meets a small amount of water.
Potassium Lignosulphonate can be used as an intermediate for dyes and is widely used in the dye industry. It can help dyes to disperse and dissolve better and improve the dyeing effect.
Lignosulfonic acid is widely use in industries such as refractory materials, ceramics, casting, briquette, feed, organic phosphate fertilizer, water-coal slurry, synthetic resins and adhesives. It plays an important role in water-coal slurry manufacturing, mining flotation, smelting granulation, asphalt emulsification, concrete admixtures, oil field production, industrial water treatment, environmentally friendly resins, ceramics, refractory materials, as well as construction, energy, chemical industry, light industry and other industries.

The preparation method of ammonium lignin sulfonate is generally to obtain the cellulose from wood waste by chemical treatment. The specific preparation method may include steps such as cellulose alkali treatment, sulfonation reaction, etc.
Lignosulfonic acid is a non-flammable compound, but it may decompose at high temperatures and produce toxic gases. During storage and transportation, it needs to be keep away from fire and oxidants.
In summary, Lignosulfonic acid has a wide range of applications in industry, including dye industry, building materials and other fields. Its versatility and environmentally friendly properties make it an important additive in many industrial processes.
