Calcium lignosulfonate
The product effluent from the pulp manufacturing process through advanced too strict. Calcium-based, low-sodium, low sulfur content, PH value is close to neutral (weak base), easily soluble in water and soluble in water, very little foam and water insoluble, product stability, combined with high intensity.
Used as concrete water reducer: doped cement 0.25 ~ 0.3%, can reduce water consumption 10 to 14 above, to improve the workability of concrete, improve project quality. Summer use, can inhibit the slump loss, are generally related to the use of superplasticizer compound.
2, used as a mineral binder: smelting industry, the use of calcium lignosulfonate and slag mixture made of slag balls, dried into the kiln, you can greatly improve smelting recovery.
3, Refractories: Production of refractory bricks, the use of calcium lignosulfonate dispersant and adhesives, can significantly improve the operational performance and has reduced water, increased, to prevent cracking and other good results.
4, ceramics: calcium lignosulfonate used in ceramic products, can reduce the carbon content increased green strength to reduce the amount of plastic clay, mud flow is good, to improve yield 70-90%, sintering rate was reduced to 70 minutes by 40 minutes .
5, used as a feed binder can improve the preference of livestock and poultry, grain strength, to reduce the amount of feed powder to reduce the powder anti-return rate and reduce costs. Mode to reduce the losses, productivity increased 10-20%, the United States and Canada allow the dosage in the feed was 4.0%.
6, Other: calcium lignosulfonate can be used for refining additives, foundry, pesticide wettable powder processing, coal suppression, mining, mining beneficiation election agent, roads, soil, dust control, leather tanning filler, black granulation and so on.
