Application 

Sodium lignosulphonate uses sodium fertilizer's properties make it suitable for a wide variety of applications in textile dyestuff, Concrete admixture, metallurgic engineering, petroleum industry, pesticides, Carbon black, Animal feed, and porcelain, etc.

Specification

Construction concrete additive 

sodium Lignosulphonate powder can be applied as common water reducing admixture and built material of series multifunction high-performance water reducers. Sodium Lignosulphonate could improved strength and durability of the cured concrete. Reduced formulation cost and Increased workability of the concrete mix. Suitable for concrete, high fluidity concrete, pumping concrete, concrete products and concrete construction in summer as well as retarding the special requirements of concrete, concrete piles, concrete piles sink, hand-dug piles of concrete and underground bulk concrete construction, with good economic benefits.

Clay ceramic admixture

Experimental application of modified sodium ligninsulphonate series products of ceramic slurry, results showed that lignosulphonate has a better dispersion stability. For ceramics lignosulphonate can reduce the carbon content ,reduce the amount of plastic clay ,mud ,good liquidity,increase yield 70%-90%,splintering speed from 70minutes to 40 minutes.Sodium Lignosulphonate has been widely applied as ceramic additives/admixtures of Industry.

Stabilized emulsions in drilling fluid

Sodium Lignosulphonate series products could emulsify two liquids which are not compatible like oil and water, make them highly connected with each other. It shows a high adsorption affinity for a wide range of chemical substrates, like oil, fat and wax so lignosulphonate could work as emulsion stabilizers. Sodium Lignosulphonate, prominent among various stabilizing agents, have been used successfully for several years in both lime-base and brine-based fluids.

Dyestuff additive

Sodium lignosulphonate as dispersant has good heating stability, lower staining ability, minimize foaming. Sodium lignosulphonate can betterclay workability, reduced need for die lubrication,life of wearing parts,free water also reduced energy consumption;quick drying ,increase greenth. reduced Baryum Carbonate need, even up to its elimination.

Leather tanning

One of the excellent property of sodium lignosulphonate used as tanning agent is irreversible suitability bonding of vegetable tannins. Lignosulphonate retarder has influence in the early development of strength with its main purpose of retarding. The cement slurry containing sodium lignosulphonate retarder is successfully used in oil industry with th advantages.e extra

Soil improvement agent & plant growth regulator on Agriculture

Sodium lignosulphonate as soil conditioner/soil improvement agent are often used to reduce shrinkage yet maintain after-forming mechanical strength (because reduced amounts of plastic clays are needed). Especially, for the chemical fertilizer granulation, could make the wet past into granulation under low pressure extrusion is used for the conversion of powders into granules.

Main Performance1,It can reduce 10% of water consumption at least;2,It can improve mixture of the concrete;3,There will be improvement for compression strength by more than 15% equally in 3-       28 days;4,It can reduce the heat of hydration in initial stage of the cement by a large margin;5,There is no corrosion on the concrete reinforcing bar.

Operation Method1,When 0.2-0.3% of mixing amount is in concrete (with cement weight), users can adjust the mixing amount through the test.2,It can be used after mixing liquid, also can be put with cement , aggregated into mixer to use at the same time also. The time is needed to be lengthened properly.
