Calcium lignosulfonate is a multi-component polymer anionic surfactant, the appearance of light yellow to dark brown powder, can contain up to 30% reducing sugar. The pH value of 1% aqueous solution is about 4 ~ 6.Spray drying of waste cooking liquid, usually from acid pulping or sulfite pulping. Soluble in water, but insoluble in any common organic solvent.slightly aromatic smell, molecular weight is generally between 800 ~ 10000, has a strong dispersion, bonding, chelation.

Specification

Application

 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.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.

1.The calcium lignosulphonate series products can be adopted as the adhesives in the briquetting procedure in the vertical retort zinc smelters
2. Can be applied as common water reducing admixture and built material of series multifunction high-performance water reducing admixtures.
3. Can be adopted as the adhesives in the briquetting procedure in the vertical retort zinc smelters.
4. Can be used as embryo reinforcing agents in the fields of pottery and porcelain and refractory materials. They can increase the fluidity of the slurry and thus to improve the strength of the embryo.
5. In the field of water-coal paste, the calcium lignosulphonate series products can be adopted as the main compound materials.
6. In agriculture, the calcium lignosulphonate series products can be applied as the dispersant agents of pesticides and pelleting adhesives of fertilizers and feedstuffs.
7.In agriculture, the calcium lignosulphonate series products can be applied as the dispersant agents of pesticides and pelleting adhesives of fertilizers and feedstuffs Technology data
