Applications:
1. Concrete water reducing agent: powdery low gas retarding water reducing agent, belongs to anionic surface active substance, adsorption and dispersion of cement, can improve various physical properties of concrete. Reduce water more than 13%, improve the workability of concrete, and can greatly reduce the initial hydration heat of cement hydration, can be compounded into early strength agent, retarder, antifreeze agent, pumping agent, etc., and naphthalene series high-efficiency water-reducing agent made of liquid admixture basically without precipitation.
Coal water slurry additive (2) : add this product in the process of preparation of coal water slurry, can increase the mill output, maintain normal power consumption, to reduce the pulping pulping system condition, improved the coal-water slurry concentration, in the process of gasification, oxygen consumption, coal consumption fell, the cold gas efficiency, and can reduce coal water slurry viscosity and reaches a certain stability and liquidity.
3. Dye industry and pesticide processing filler and dispersant: used as VAT dyes and disperse dyes dispersant and filler, can make the dye color increase, color more uniform, shorten the time of dye grinding; It can be used as filler, dispersant and suspension agent in pesticide processing, greatly improving the suspension rate and wettability of wettable powder
Sodium lignosulfonate (wood sodium) is an extract from bamboo pulping process, which is condensed and modified by spray drying. The product is light yellow (brown) free flowing powder, easily soluble in water, stable chemical properties, long-term sealed storage will not decompose. Lignin series products are a kind of surface active agent, can through the methods of modification, processing, production of multiple products, mainly used for resin, rubber, dyes, pesticides, ceramic, concrete, asphalt, feed, water treatment, coal water slurry and concrete, refractory materials, oil field drilling, compound fertilizer, smelting, casting, adhesives. Experiments show that lignosulfonate is very effective in preventing sandy soil, and can also be used as a sand fixation agent in desert.
