Sodium lignosulfonate (sodium) is a bamboo pulping process extract, after concentrated and modified by spray drying. The product is light yellow (brown) free flowing powder, soluble in water, chemical stability, long-term sealed storage without decomposition. Lignin products are a kind of surfactant, which can produce many products by modification, processing, compound and other methods. It is mainly used in resin, rubber, dye, pesticide, ceramics, cement, asphalt, feed, water treatment, water Coal slurry, concrete, refractory material, oilfield drilling, compound fertilizer, smelting, casting, adhesive. Experiments show that lignosulfonate to prevent sand soil is very effective, but also can do desert fixed sand. The main features are:
1, concrete water-reducing agent: the Department of powder low bleed air retarding water-reducing agent, anionic surface active substances, the adsorption and dispersion of cement, can improve the physical properties of concrete. Reduce the water more than 13%, to improve the workability of concrete, and can significantly reduce the early hydration of cement hydration heat, can be compounded into early strength agent, retarder, antifreeze, pumping agent, and naphthalene efficient The addition of the water-reducing agent to the liquid admixture is substantially free of precipitation.
2, coal-water slurry additives: in the preparation of coal-water slurry process to join the product, can improve the high mill production, to maintain the normal conditions of the pulping system to reduce the pulp power consumption, so that the concentration of coal-water slurry in the gasification process , Oxygen consumption, coal consumption decline, the efficiency of cold gas increased, and can reduce the viscosity of coal-water slurry and achieve a certain degree of stability and mobility.
3, refractory and ceramic body reinforcement: in the large-scale tiles and refractory brick manufacturing process, can make the raw material particles firmly bonded together, can dry billet strength increased by 20% -60% or more.
4, the dye industry and pesticide processing of fillers and dispersants: used as a reducing dye and disperse dyes dispersants and fillers, can increase the dye color, color more uniform, shorten the time of dye grinding; in pesticide processing Can be used as fillers, dispersants and suspending agents, greatly improve the wettable powder suspension rate and wetting properties.
5, as a powder and granular materials of the binder: for iron ore powder, lead-zinc ore powder, pulverized coal, coke powder pressure ball; cast iron, cast steel sand type suppression; mud brick tiles and other extrusion Molding; mineralization into the ball can get high strength, good stability, lubrication molds and other good results.
6, in the drilling as dilution dispersant, viscosity reducer; to improve the flow of crude oil transport, reduce energy consumption. In petroleum products, as a clean agent, dispersant, overbased additives, rust inhibitors, antistatic agents, emulsifying viscosity reducer, wax and wax protection agent.
