Lignosulfonate manufacture process 1.Pulping This is the first step ,with purpose to separate cellulose from lignin and others.thus lignin is become the form of water soluble and insoluble lignin is get rid off. Raw material wood chips,sulfite like calcium sulfite,sodium sulfite and so on.Put them into digester vessel to start pulping process under steam pressure. […]
Lignosulfonates could be used in oil drilling working as deflocculants, chemicals to prevent the coagulation of solids.Lignosulfonateand Modified lignosulfonate 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 […]
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 used in concrete Usage of lignosulfonates on the base of sodium, relating to the hydrofilizing plastificators, at the concrete manufacture and dry construction mixtures lets to reduce the consumption of components up to 10-15%. Demixing of the concrete mass reduces and its solidity rises, the speed of hardening slows down. They insert additives of […]
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 […]
Calcium lignosulfonate is obtained from soft wood processed in sulfite pulping method for producing paper.They small pieces of softwood is put into reaction tank to react with acidic calcium bisulfite solution for 5-6 hours under the temperature of 130 degree Centigrade.During the process the bisulfite ions reacted with native lignin to for sulfonated lignin, that […]
