| Name | Sodium Lignosulfonate |
| Chemical Name | Lignosulfonic Acid Sodium Salt |
| CAS NO. | 8061-51-6 |
| EINECS NO. | 23-25-059 |
| Application | 1.Concrete Admixture: Sodium lignosulfonate can be used as water reducer in concrete, the water reducing rate is 8-9%. And it also can be used as retarder, early strength agent, air entraining agent, pumping aid agent and so on. If you want to used in cement, also can be cement grinding agent. 2.Dispersing: Sodium lignosulfonate is a high weight electrolyte containing sulfonate, carboxyl and phenol hydroxyl groups. It is absorbent to organic and inorganic particles chemically or physically, and keeps them dispersing stably due to its strong hydrophilic property and negative charges. 3.Binding: Lignosulfonate has a binding property since it is a high polymer. It has an excellent binding property since it contains not only lignosulfonate but also reduces sugar and sugar sulfonate. 4.Chelating: Lignosulfonate and sugar derivatives have a chelating property making hydrophilic or hydrophobic compounds since they contain sulfonate, carboxyl and phenol or alcohol hydroxyl groups and they are absorbent to polyvalent metal ions. |
| Storage | Kept in dry and ventilating place, prevent from rain and moisture when storage if agglomerated, please crush and make it into solution, and its effect will be the same. |
