Lignin

Specifications

Introduction of lignin

Lignin and wooden calcium (calcium lignosulphonate), is a kind of multicomponent polymers anionic surface active agent, appearance for tan powder material, slightly fragrant smell, average molecular weight between 800-10000, has a strong dispersion, bonding, chelate. The calcium lignosulphonate has been widely used as cement water reducing agent, binder and refractory ceramic body strengthening agent, CWS dispersants, pesticide suspension agent, leather tanning agent, carbon black, granulation, etc., are very popular with the masses of users.

Lignin characteristics

1, the effective content of calcium lignosulphonate, is the derivatives of phenyl propane

2, anionic surfactant, good water solubility

3, the concentration of the strong cohesive force, increase the strength of viscous, when the concentration of more than 50%, significantly higher bonding degree.

4, good chemical stability, not burning, not explode, non-toxic harmless.

5, can compound modification, deep processing into various products.

Lignin purposes

1, used as a concrete water reducing agent, mixing quantity of cement 0.25 ~ 0.3%, water consumption can be reduced more than 10 ~ 14, improve the workability of concrete, improve the quality of engineering. Summer is used, can inhibit the slump loss, generally is used with high efficiency water reducing agent.

2, used in powder metallurgy bonding agent: in mineral processing, used as a flotation agent, improve the processing precision and speed; When smelting, mix with lignin and mineral powder, made from mineral powder ball, after drying in the kiln, smelting recovery can be greatly improved.

3, refractory materials, manufacturing refractory brick, the use of lignin dispersant and adhesive, can significantly improve performance, and has good water reducing, enhancing and prevent cracking effect.

4, pottery and porcelain: lignin used in ceramic products, can reduce the size of grinding time, reduce carbon content increase green strength, reduce plastic clay dosage, good mud flow, improve the yield of 70-90%, sintering speed by 70 minutes reduced to 40 minutes.

5, used as adhesives, feed for livestock and poultry diets can be improved, particle strength, reduce the amount of powder feed, reduce powder return rate, reduce the cost. 

6 micro (change), biological fertilizer industry, lignin is not only used as adhesive, used for granulation forming agent; Also can be used as an important source of fertilizer nutrients.

7, rubber additives and fillers in rubber mixing process can be added a lot of, can be more than 1.5 times of rubber base, and don't have to add softener.
