Usage :
Sodium lignosulfonate (sodium lignin) is an extract from bamboo pulping process.The product is light yellow (brown) free flowing powder, easy to dissolve in water, stable chemical properties, long - term sealed storage does 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. It has been proved that lignin sulfonate is very effective in preventing sandy soil and can also be used as desert fixing agent.
1.Water reducing agent for concrete: it is a powdery low-gas retarding water reducing agent, which is an active substance on the surface of anion. It has adsorption and dispersion effect on cement, and can improve various physical properties of concrete. Reduce more than 13% water, improve the workability of concrete, and can greatly reduce the cement early hydration heat of hydration, can mix into early strength agent, retarder, antifreeze, pumping agent, after with naphthalene series high efficient water reducing agent to liquid admixture made of basic no precipitate is formed.
2, coal water slurry additive: 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. Refractory materials and ceramic body strengthening agents: in the manufacturing process of large-size wall tile and firebrick, the particles of the raw material of the billet can be firmly bonded, and the strength of the dry blank can be increased by 20-60%.
4, dye industry and pesticide processing filling agent and dispersant: used for VAT dyes and disperse dye dispersants and filling agent, can make the color dye, color more even, shorten the time of the dye mill; In pesticide processing, it can be used as filler, dispersant and suspending agent to greatly improve the suspension rate and wettability of wettable powder.
5. As a binder for powder and granular materials: used for pressing balls of iron ore powder, lead-zinc ore powder, coal powder and coke powder; Compression of cast iron and cast steel sand; Mud brick wall floor tile extrusion molding; The pellet formation of ore can obtain high strength, good stability, lubrication mold and other good results.
6. Used as dilution dispersant and viscosity reducer in drilling; Improve the flow of crude oil and reduce energy consumption. In petroleum products, it is used as cleaning agent, dispersant, high alkaline additive, anti-rust agent, antistatic agent, emulsifying viscosity reducer, dewaxing anti-wax agent, etc.
Features and benefit
1. Water reducing rate can be up to 9-11% in the appropriate mix content, compared with the reference concrete strength increase 15-20%, 3 days, 7 days strength increased 20-30%, 28 days increase 15-20%, also increase long-term strength.
2. With same water condition of concrete, could increase the fluidity of concrete, improve workability.
3. Keep the same concrete slump and strength, could save cement 8%-10%.
4. Can dely the initial setting time of concrete more than 3 hours, final set time 3 hours, the hydration heat peak delay 5 hours. It is good for summer construction and commercial concrete transportation and mass concrete engineering.
5. This product has entraning air function, the permeability of concrete freeze-thaw performance can be improved.
6. No corrosive for steel and aggregate.
