Description:

Sodium Lignosulfonate is yellow brown powder completely water soluble,is naturally anionic surfactant of high molecular polymer, rich in sulfo and carboxyl group and has better water-solubility, surf-activity and dispersion capacity.Could be used for construction, ceramics, mineral powder, chemical industry, textile industry (leather), metallurgical industry, petroleum industry, fire-retardant materials, rubber vulcanization, organic polymerization,also could used as animal feed additives due to its antimicrobial and preservative properties.

Composition: It is made from the liquid waste of sulfite pulping throughChemical modification, moderate

Molecular weight and low reducing sugar content.

CAS No.:8061-51-6

Molecular Formula: C20H24Na2O10S2

Formula Weight: 534.51

 

 

Application:

 

1.Could work as plasticizer in making concrete n making concrete to maintain the ability of concrete flow with less water.Also used during the production of cement, where they act as grinding aids in the cement mill and as a rawmix slurry deflocculant (that reduces the viscosity of the slurry).

2. Could be used in lead batteries to acts on crystallization of the lead sulfate thus increase the battery to get a much longer life-time.

3. Could used as a filler and binder in ceramic tiles, resins to fiber boards, casting sand and in fodder pellets.

4.Work as dust-suppression roads as well as in dusty processes within industry. Lignosulfonate is used as a dispersant in products like fodder, disperse pesticides, dyes,carbon black, and other insoluble solids and liquids into water.

 

5. Could reduce the viscosity of mineral slurries is used to advantage in oil drilling mud, where it replaced tannic acids from quebracho (a tropical tree).

6. Could be used for the production of plasterboard to reduce the amount of water required to make the stucco flow and form the layer between two sheets of paper. the reduction in water content allows lower kiln temperatures to dry the plasterboard, saving energy.

7. Lignosulfonates could work as a binder of powder and granular materials: for iron ore powder, lead and zinc powder, pulverized coal, coke Toner pressure on the ball; extrusion of cast iron, cast steel sand repression; mud-brick wall and floor tiles molding; mineral aggregate into a ball and provides high strength, good stability, lubrication and mold good results.

Advantage as Water Reducer:

 

1.Low dosage, low air content, high compatibility with cement,

No sediment When compounded withNaphthalene-based superplasticizer

2.Water reducing rate over 14%.

3.Greatly enhanced the workability of concrete.

4.Greatly reduce the hydrating heat during initial stage of cement hydration.

5.No concrete salts content,no corrosion to rebar.

6 No alkali active substance

 

 

Usage and dosage:

 

1 the recommended dosage of sodium lignosulfonatein in concrete is 0.2% ~ 0.6% (weight of cement), the user should

 determine the optimal dosage through the experiment.

2 the sodium lignosulfonate can be made into liquid.

3 the sodium lignosulfonate , matched with Naphthalene Sulfonate has remarkable effects. the dosage and proportion, users should according to the varieties of cement, aggregate and Naphthalene Sulfonate to determine after the 

Experiment.

4 when using Sodium Lignosulfonate, the dosage should be strictly controlled, too little will conduct to the effect is not 

Obvious, too many will effect early strength.

5 when the temperature is below 5 ℃, it usually should't be used alone in concrete engineering.

 

 

Package and delivery:

in powder form the admixture is packed in polypropylene or paper sacks with polyethylene insert of 25-40 kg or big-bags 650 kg and delivered by means of auto transport, railway cars and marine containers.
