Prodcut Details
Lignosulfonates are compatible with anionic and non-ionic materials, dispersants, wetting agents and most organic and inorganic materials.
Calcium Lignosulphonate can work well with other chemicals and produce early strength agent, slow setting agent, antifreeze and pumping agent.The pH value of 1% aqueous solution is about 4 ~ 6.Spray drying of waste cooking liquid, usually from acid pulping or sulfite pulping. Can contain up to 30% reducing sugar. Soluble in water, but insoluble in any common organic solvent.
Name: Calcium Lignosulphonate
CAS No.: 8061-52-7
MF: C20H24CaO10S2
It is a kind of natural anionic surface active agent processed with sulfurous acid pulping waste through advanced production technology.. It is widely used in various concrete projects such preformed concrete, reinforced concrete and prestressed concrete, esp ecially applicable for commercial concrete, anti-freezing concrete, waterproof concrete, bulk concrete, pumping concrete, with high economic benefit.

Application
Calcium lignosulfonate is a multi-component polymer anionic surfactant, the appearance of light yellow to dark brown powder, slightly aromatic smell, molecular weight is generally between 800 ~ 10000, has a strong dispersion, bonding, chelation. Calcium lignosulfonate can be used for refining auxiliaries, casting, pesticide wettable powder processing, briquette suppression, mining, mineral dressing agent, road, soil, dust control, leather tanning packing, carbon black granulation and so on.
1. Used as concrete water reducer
Cement content of 0.25 ~ 0.3%, can reduce the water consumption of 10 ~ 14 above, improve the workability of concrete, improve the quality of the project. Summer use, can inhibit the slump loss, usually combined with efficient water reducing agent.
2. Used as mineral binder
Smelting industry, with calcium lignosulfonate mixed with ore powder, made of ore powder ball, dry into the kiln, can greatly improve the smelting recovery.
3. Used as refractory
Using calcium lignosulfonate as dispersant and adhesive in the manufacture of refractory bricks and tiles can significantly improve the operation performance, reduce water, strengthen, prevent cracking and other good effects.
4. Used as ceramic
Calcium lignosulfonate used in ceramic products, can reduce carbon content increase green strength, reduce plastic clay dosage, mud flow is good, improve the yield of 70-90%, sintering speed from 70 minutes to 40 minutes.
5. Used as a feed binder
Can improve livestock and poultry feeding, particle strength is good, reduce the amount of micro powder feed, reduce powder return rate, reduce costs. The loss of mold was reduced, the production capacity was increased by 10-20%, and the allowable content of feed in the United States and Canada was 4.0%.
6. Other industry
Calcium lignosulfonate can also be used for refining auxiliaries, casting, pesticide wettable powder processing, briquette suppression, mining, mineral dressing agent, road, soil, dust control, leather tanning packing, carbon black granulation and so on.
