Application of sodium lignosulfonate:Use 1: it is mainly used as cement water reducer to diffuse the agglomerated cement, separate out the water contained, and increase its fluidity. So as to reduce mixing water and save cement. When it is used in the formulation of oil drilling mud, it can effectively reduce the viscosity and shear force of the mud, so as to control the fluidity of the drilling mud, keep the inorganic soil and inorganic salt impurities suspended in the drilling, prevent the mud from flocculation, and have outstanding salt resistance, calcium resistance and high temperature resistance. Lignosulfonate is a natural macromolecular compound with molecular weight of 1000 ~ 30000. It is made from the leftover from the production of pulp after fermentation and extraction of alcohol, and then neutralized with alkali. It mainly includes calcium lignosulfonate, sodium lignosulfonate, magnesium lignosulfonate, etc. the most widely used calcium lignosulfonate is made from sulfite pulp waste liquid. This kind of water reducing agent has abundant raw materials, simple manufacturing process and low price. It is widely used in China, accounting for about 80% of the total output of water reducing agent. However, its effect is not very good. It has the functions of air entrainment and retarding. It is a common water reducer and has a good effect when combined with early strength agent.
Use 2: used as concrete water reducer, dispersant for oil drilling mud, printing and dyeing dispersant, etc. used as concrete water reducer, dispersant for oil drilling mud, printing and dyeing dispersant, etc
Use 3 refractory materials and ceramic body reinforcer: in the manufacturing process of large-scale wall and floor tiles and refractory bricks, the raw material particles of the body can be firmly bonded, and the dry strength of the body can be increased by more than 20% - 60%.
Use IV filler and dispersant for dye industry and pesticide processing: when used as dispersant and dispersant for vat dyes and disperse dyes, it can increase the color power of dyes, color more evenly, and shorten the grinding time of dyes; It can be used as filler, dispersant and suspending agent in pesticide processing, and greatly improve the suspension rate and wettability of wettable powder.
Use 5 as binder for powdery and granular materials: used for pressing iron ore powder, lead-zinc ore powder, pulverized coal and coke carbon powder; Pressing of sand mold of cast iron and cast steel; Extrusion molding of mud brick wall and floor tile; High strength, good stability and good effect of lubricating mould can be obtained in the pelletizing of mineral aggregate.
Use 6: used as diluting dispersant and viscosity reducer in drilling; Improve the fluidity of crude oil transportation and reduce energy consumption. In petroleum products, it is used as cleaner, dispersant, high alkaline additive, rust inhibitor, antistatic agent, emulsion viscosity reducer, paraffin remover, paraffin inhibitor, etc.
Appearance character: Brown powder
Storage conditionsMulti layer paper bag packaging. Store in a cool, dry and ventilated place. Moisture proof
Stability1. it has good diffusion performance, can be dissolved in water of any hardness, and has good chemical stability and biodegradability.
2. lignosulfonate, also known as sulfite lignin, is a heterogeneous anionic polyelectrolyte with different relative molecular weight and different structure, that is, it has polydispersity. The solid product is yellowish brown free flowing powder with hygroscopicity. It is easily soluble in water and is not affected by the change of pH value, but it is insoluble in ethanol, acetone and other common organic solvents. The aqueous solution is brown to black and has colloidal properties. The viscosity of the solution increases with the increase of concentration. Lignosulfonate has little effect on reducing the interfacial tension between liquids, and can not reduce the surface tension of water or form micelles. Its dispersion mainly depends on the adsorption desorption of matrix and the generation of charge.
