Lignin Process


Lignin is a chemical compound, which is usually separated from the tree, which is a lot of plants and algae in the second layer is the main component of cell walls. 1819 De Candolle introduced the concept of lignin, this phrase from Latin lignum, meaning trees. In woody plants, the lignin is the world’s second […]

lignin properties

lignin-properties Different pulping processes and lignin extraction method to obtain the main physical and chemical properties include the following: 1, the color of lignin Original lignin is a white or nearly colorless material. We see the color of lignin, in isolation, caused by the preparation process. With the separation of the different preparation methods, showing […]

lignin Structure

The molecular structure of lignin

Lignin is composed of four alcohol monomer (p-coumaric alcohol, Coniferin 5 – hydroxy Coniferin, mustard alcohol) to form a complex phenolic polymer. Lignin is a component of plant cell walls constituting, with the role of the cell is connected. Lignin is a negatively charged group containing many polycyclic organic polymer on soil metal ion has […]


Calcium lignosulfonate uses in concrete

Calcium lignosulfonate in concrete action and dosage – Stone Refractories I. Calcium lignosulfonate water reduction in concrete reinforced role Calcium lignosulfonate and sodium lignosulfonate reducing agent is a surface-active agent, added to the concrete, due to the orientation of hydrophobic groups adsorbed on the surface of cement particles, so that the cement with a negative […]
