The molecular structure of lignin

The molecular structure of lignin Lignin is composed of four alcohol monomer (p-coumaric alcohol, Coniferin 5 – hydroxy Coniferin, mustard alcohol) to form a complex phenolic polymer. Lignin is a component of plant cell walls constituting, with the role of the cell is connected. Lignin is a negatively charged group containing many polycyclic organic polymer […]

Calcium lignosulfonate in concrete action and dosage – Stone Refractories I. Calcium lignosulfonate water reduction in concrete reinforced role Calcium lignosulfonate and sodium lignosulfonate reducing agent is a surface-active agent, added to the concrete, due to the orientation of hydrophobic groups adsorbed on the surface of cement particles, so that the cement with a negative […]

Calcium lignosulfonate Properties

Calcium lignosulfonate (referred wood calcium) is a multi-component polymer anionic surfactant, the appearance of brown powdery substance, slight aroma, molecular weight is generally 800 to 10000, with a strong dispersion, bonding, chelation. Currently calcium lignosulfonate products have been widely used as a cement water reducing agent, pesticide suspensions, ceramic body enhancers, CWS dispersants, leather tanning […]

Lignosulfonate used in oil drilling

Lignosulfonate-used-in-oil-drilling Lignosulfonate used in oil drilling 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 process and extend the use of the bentonite.  Using purpose In oil industry – used as reagent for regulation of drilling agent; In chemical industry –used as the stabilizer, dispersing agent for manufacture of briquetted means of plants protection; In cement industry and manufacture of castables -used as cement softener and  binding material. Function In the oil refining and oil industry for drilling oil and gas wells lignosulfonates are used as a reagent to control the basic parameters of drilling fluids. Also, they are a component of gelling systems, which are low-viscosity solutions with pH 2.5-3.0. The formation of the gel leads to the redistribution of filtration flows and their better management, alignment profile pick-injection wells,restriction of water in the process, which in turn increases the recovery of oil. Using these systems lignosulfonates is possible by adsorbingproperties of surface-active additives. Just as in the mining industry, technical lignosulfonates are used to enhance various types of structures: mud pits, wells, etc.   In the petroleum refining and oil producing industries lignosulfonates are used as a flotation agent and reagent for regulating of the basicparametres of mud flushes. Also they are a component of gel forming systems – low-viscous solution with pH 2.5-3.0. Gel forming leads to  predistribution of filtration flows and their better regulation, annealing of injectability prophile, limit of inflows of water in processes, what rises oil production. Usage in these systems of lignosulfonates is possible by means of adsorbing properties of tensioactive additives. Technical lignosulfonates are used for hardening of different construction types: drill well moonpool, holes, etc, as well as in minerals industry.

Lignosulfonate used in concrete

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 lignosulfonates in the […]

Lignosulfonate used in smelt industry

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 work as dust control agent

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 […]

About Lignosulfonate

Lignosulfonates are when traded a brown amorphous powder. They have no odour and they are not hygroscopic. They form colloidal solutions or dispersions with water but are not soluble in organic solvents. Lignosulfonates are biopolymers; they are salts of lignosulfonic acid that has been formed when pulp is manufactured by the sulphite method. The lignosulfonates […]
