Lignosulfonate Cement Retarder for Oil-Well Cementing
.
In oil and gas well cementing, the slurry must stay pumpable for the whole placement job, then set and gain strength once it is…

Lignosulfonate as a Metal-Complexing and Adsorbent Aid
.
Lignosulfonates can be evaluated as metal-complexing or metal-adsorbing aids in selected industrial systems. The carboxylate and sulfonate functional groups present on the lignosulfonate backbone…
-
Lignosulfonate Used as a Flocculant
.
Lignosulfonates and sulfonated lignin have long been evaluated as flocculants to help decrease settling time in suspensions and slurries, and to increase the density…
-
How Lignosulfonate Works as a Dispersant: Mechanism and Qualification
.
Dispersant and concrete-admixture use accounts for a large share of industrial lignosulfonate demand. The functional basis is molecular: lignosulfonates are polydisperse, water-soluble anionic polymers…
