Cement Grinding Aid Sodium Lignosulfonate

Description

The sodium lignosulphonate, which is prepared from straw and wood mix pulp black liquor through filtration, sulfonation, concentration and spray drying, and is a powdery low air-entrained set retarding and water reducing admixture, belongs to an anionic surface active substance, has absorption and dispersion effect on the cement, and can improve various physical properties of the concrete.

Performance

1. To improve the cement mill output : After adding the aids, under the premise of maintaining or slightly improving the cement’s physical properties, the mill production capacity can be increased by 10 %.

2. Reduce the mill consumption: by improving the powder’ surface charge performance inside the mill, it can eliminate the " pastes surround the grinder" phenomenon; meanwhile the aids can improve the micro- cracks’ extending of the powder particles, improve the grinding efficiency, thereby reduce the miller energy consumption, cement mill per tonne of power consumption can be reduced by 10-20% .

3. To prevent " excessive grinding " and reduce the grinding temperature : because of the grinding efficiency’s raising, accelerate the cement mill’s passing speed, to avoid " over-grinding " phenomenon, thus reducing the mill inside temperature. Grinding temperature’s decrease can prevent dihydrate gypsum’s dehydration, to improve the setting time and strength development and other cement performance.

4. To improve the cement’s physical performance: to improve the cement strength ( especially 10-20 % improve the early strength) or shorten setting time ( especially the final setting time ) ; take advantage of added the grinding aids can help improve the cement’s performance, can increase the mixing content amount, or add of part of the shaft kiln cement clinker in rotary kilns to reduce costs.

5. To reduce powder surface adsorption energy: Adding the aids can help reduce powder surface’s static enrichment, to avoid the powder clumping and compaction to harden, eliminating cement silo bottom "bonding " phenomenon ; improve powder mobility, reduce transportation energy consumption;

6. Economic analysis by using cement grinding aids (Take 100T per year output cement companies for example )

Application

1. Can be used as a water-reducing admixture for concrete, and applicable for projects such as culverts, dikes, reservoirs, airports, expressways and so on.

2. Used as a scale remover and a circulating water quality stabilizer on boilers.

3. Sand preventing and sand fixing agents

4. Used for electroplating and electrolysis, and can ensure that the coatings are uniform and have no tree-like patterns.

5. Used as a tanning auxiliary in leather industry.

6. Used as a flotation agent for ore dressing and an adhesive for mineral powder smelting.

7. Coal water slurry additive

8. Long-acting slow-release nitrogen fertilizer agent, a modified additive for high-efficiency slow-release compound fertilizers

9. Used as a filler and a dispersant for vat dyes and disperse dyes, a diluent for acid dyes and so on.

10. Used for anodal anti-piping agents of lead-acid storage batteries and alkaline storage batteries, and can improve the low-temperature urgent discharge and service life of the batteries.
