Chemical Lignosulfonic Acid Sodium Salt CAS 8061-51-6 For Concrete Water Reducer

Sodium Lignosulphonate used as concrete water reducer

Sodium Lignonsulphonate:

Sodium lignosulfonate (sodium salt of lignosulfonic acid) is a natural polymer and anionic surfactant. Its appearance is brown powder or liquid, no special odor, non-toxic, easily soluble in water and lye, precipitated by acid, and has strong dispersing ability. As a kind of surfactant, sodium lignosulphonate can produce multiple products through modification, processing, compounding and other methods, mainly used in concrete, cement, resin, rubber, dye, pesticide, ceramics, asphalt, feed, water treatment , coal water slurry, refractories, oil field drilling, compound fertilizers, smelting, casting, adhesives.

How to use it

1. During the construction process, we must strictly control the dosage. Once the amount is too large, it may cause the coagulation time to be significantly prolonged.
2. Product delay increases significantly as temperature decreases. The lower the temperature, the slower the strength increase.
3. The sodium lignosulfonate powder is easily soluble in water and can be formulated into an aqueous solution of 1％-50％ When dissolving, put water into the container first, then quickly add sodium lignin sulfonate while stirring to avoid agglomeration or prolong dissolution time. After being formulated into a solution, it should be used up within ten days to prevent mildew.
4. Before use, we need to carry out the adaptability test of the cement variety. This is because concrete water reducers must be tested and meet the technical requirements before they are put into engineering use.
5. For concrete with air-entrained amount, when the air-entrained amount is too large, it is necessary to choose an appropriate vibration time or take other defoaming measures to make the air content meet the technical requirements.

Packaging and storage

1. Powder products are made of chemical fiber woven bags, lined with plastic film bags, each bag net weight (40±0.2kg) or (25±0.2kg) or (750±0.2kg), can also be customized according to customer requirements.

2. Powder products should be stored in dry and ventilated special warehouse, products such as damp caking can be crushed or dissolved into water agent use does not affect the actual effect.
