Lignosulfonates could be used in oil drilling working as deflocculants, chemicals to prevent the coagulation of solids.lignosulfonates from wood pulp provides a chemical that is stable at the high temperatures- 150 to 250 degrees F– that occur in well bores during drilling. Clay minerals in drilling mud, such as bentonite,often coagulate.Lignosulfonates halt this process and […]

The application of lignosulfonates is widely spread as a binding material for sand and core sand mixtures in foundry. During manufacture of sand and core sand mixtures for cast iron, non-ferrous and steel casting lignosulfonates replace some deficit and toxic materials: phenolic alcohols, carbamide-formaldehyde, phenolformaldehyde pitchs. While using binding substances on the base of lignosulfonates […]

lignosulfonate-dust-control Lignosulfonate could work as naturally binder as its original form of lignin to bind the cellulose and fiber,so it can be used binding agent in pellets or compressed materials,also could used as dust control agent,which will be much more environment friendly and lower cost compared with Chloride. How lignosulfonate control the dust Lignosulfonate binds […]

Lignosulfoantein architectural ceramics Applications Currently in building ceramic body used in the formulation additives are mainly two: one is body enhancer , mainly used to increase the strength of the body , is mainly used in low viscosity carboxymethylcellulose is CMC; a coagulant solution species are primarily used to reduce the viscosity of the mud […]
