nature : also known as lignin sulfonate. Paper pulp by-products. A linear polymers. Tan solid, a good diffusion. Used in the manufacture of vanillin, replacing 50% of phenol and formaldehyde condense plastic products. Usually sulfite pulp from the liquid waste processing enrichment, with lime, calcium chloride, lead, acid precipitation Basic agent separation in Lignosulfonate crude products. According to require further increases acid dissolution, filtration addition to calcium, alkaline sodium into final evaporation drying from intensive products. Lignin sulfonate (sodium lignosulfonate) is an anionic surfactant, is solid in the water medium for the excellent dispersant. The widely used industrial dispersant (such as dispersants M-9) and the wetting agent, such as oil drilling mud dispersant, superplasticizer concrete, gypsum board production additives, pesticides agents, dyeing, the proliferation of drugs, wear rubber agents.
