Sodium lignin sulfonate sodium salt/Calcium lignosulfonate

1. Introducing the wood calcium:

Calcium lignosulfonate (Calcium lignosulfonate) is a kind of multi-component polymer anionic surfactant. It is brown and yellow powder with a slight aroma. Its molecular weight is generally between 800 and 10000. It has strong dispersibility, cohesiveness and chelating property. At present, MG-1, -2, -3 series products of calcium lignosulfonate have been widely used as cement water reducer, pesticide suspension agent, ceramic body reinforcer, coal water slurry dispersant, leather tanning agent, refractory binder, carbon black granulator and so on. They are widely used in various industries and are welcomed by users.

II. Technical Indicators

Appearance brown yellow powder

Lignin content (>50-65%)

Water insoluble matter < 0.5-1.5%

PH 4.5-7

Moisture <4-7%

Reduction 7-13%

III. Main Performance

1. Used as concrete water reducer: 0.25-0.3% of cement content can reduce water consumption by more than 10-14, improve concrete and workability, and improve engineering quality. When used in summer, it can restrain slump loss, and is usually used in combination with high-efficiency water reducing agent.

2. Used as mineral binder: In smelting industry, calcium lignosulfonate is mixed with mineral powder to make mineral powder ball, which can be dried and put into kiln, and the recovery rate of smelting can be greatly improved.

3. Refractories: When making refractory bricks and tiles, using calcium lignosulfonate as dispersant and binder can significantly improve the operation performance, and has good effects of reducing water, strengthening and preventing cracks.

4. Ceramics: Calcium lignosulfonate used in ceramic products can reduce carbon content, increase green strength, reduce the amount of plastic clay, improve the fluidity of mud, increase the yield by 70-90%, and reduce the sintering speed from 70 minutes to 40 minutes.

6. Others: Calcium lignosulfonate can also be used in refining additives, foundry,  powder processing, briquette pressing, mining, mineral processing agent, road, soil, dust control, tanning filler, carbon black granulation, etc.

Packaging, storage and transportation:

1. Packaging: Double-layer packaging with plastic film lining and polypropylene woven bag for external use, 25kg/package.

2. Storage: Store in a dry and ventilated place, pay attention to moisture-proof and moisture-proof. Long-term storage does not deteriorate, if there is caking, crushing or dissolving will not affect the use effect.

3. Transportation: This product is non-toxic, harmless, non-flammable and explosive dangerous goods. It can be transported by car or train.
