alkali lignin/sodium lignin
product properties:
1. it is dark coffee color powder, belongs to macromolecule anion surface active materials, it could exchange metallic ions. Molecular weight 1000-100000. the density is low and free from water absorbent.
2. it has good disperse properties and viscosity. The viscosity of its liquid rises along with the rise of consistency, when the consistency is up to 35%, the viscosity rises obviously.
3. it has good water-solubility, high chemical stability, and could be made as 40% water solution.
