Sodium Lignosulphonate
Cas No.: 8061-51-6 HS Code:38040000
Product Introduction: Sodium Lignosulphonate is an anionic surfactant. It is a reaction product of wood pulp and sulfur dichloride aqueous solution and sulfite, which is the by product of pulp production. SLL is first generation concrete admixture, features of low ash, low gas content and strong adapt ability for cement, there is no precipitate in the liquid admixture which compound with naphthalene high-performance water reducer.
Application：
1.Construction industry: It is mainly used as a concrete admixture. It can improve the fluidity of concrete, reduce the water consumption, enhance the workability and strength of concrete, improve the dispersion of cement particles, prevent sedimentation and agglomeration, thereby improving the quality and durability of concrete. 2.Pesticide and fertilizer industry: As a fertilizer additive, it can increase the nutrient utilization rate and improve the physical properties of fertilizers. As a carrier for slow and controlled-release fertilizers, it can delay the release of nutrients and enhance the stability of fertilizers. It can also promote plant growth, stimulate the development of plant roots, and regulate the plant's metabolism. Moreover, it can improve the soil structure, increase the stability of soil aggregates, and enhance the soil's ability to retain fertilizers and water. It can be used as a pesticide dispersant, a pesticide slow-release agent, enhance the adhesion of pesticides, and improve the wettability of pesticides. 3.Dye industry: In the dye industry, it is used as a dispersant.
4.Paper industry: During the papermaking process, it can be used as both a dispersant and a strengthening agent.
5.Coal industry: It is used as a binder for coal briquettes. It can improve the strength and waterresistance of coal briquettes, making them easier to transport and store, and reducing dust and environmental pollution during their use.
6.Other applications: Sodium lignosulfonate can be used as a dust suppressant. It is also used in ceramic production as a dispersant for pigments, and in the pharmaceutical industry as an excipient, etc. As a pigment dispersant, it can make the pigments evenly dispersed in coatings, inks, and other materials. In the pharmaceutical industry, it can be used as a binder or a disintegrant in tablet formulations.
