What is difference between lignin and lignosulfonate?
.
Lignin is part of wood and is, after cellulose, the second most abundant organic molecule on Earth. Wood contains about 20–30% lignin. During sulfite…

Lignosulfonate retarder
.
Lignosulfonates retard the setting of cement. While this retardationcan occasionally be advantageous, under certain weather conditions (e.g. in cool weather) the setting time may…

Lignosulfonate Application
.
Lignosulfonates are obtained from sulfite pulping processes wherein cellulose is extracted from wood in the pulp industry. The so-called sulfite pulping process involves mixing…
