Lignosulfonate is used in paperboard production
What’s Lignosulfonate, Anyway? Lignosulfonate is a natural, sticky substance that comes from making paper. When paper mills turn wood into paper using a process called sulfite pulping, they soak wood chips in special chemicals to pull out the cellulose fibers (the stuff that becomes paper). The leftover woody part, called lignin, gets turned into lignosulfonate—a

Sodium lignosulfonate structure and property
Sodium lignosulfonate structure and property guide Sodium lignosulfonate is a water-soluble lignin derivative used as a dispersant, binder, and formulation aid. Its performance comes from a sulfonated lignin backbone, sodium counterions, broad molecular-weight distribution, and the balance between aromatic lignin segments and hydrophilic sulfonate groups. How the structure affects performance Structure feature Practical property Buyer

Sodium lignosulfonate as a concrete admixture
As a water-reducing and plasticizing admixture, it improves the workability of fresh concrete without adding extra water.The lignosulfonate polymer adsorbs onto the surfaces of cement and aggregate particles through electrostatic and hydrogen bonding.This creates electrosteric repulsion between particles, dispersing them and preventing agglomeration.The workability is increased as the inter-particle forces are reduced, allowing concrete to

Advantages of lignosulfonate over stronger synthetic superplasticizers
Lignosulfonates are a class of natural-based superplasticizers that offer several advantages over stronger synthetic superplasticizers. Here are some of the key advantages of lignosulfonates:
