Interest to lignosulfonates is due to the high surface activity, what lets to use these additives in different branches of industry - petrolium, mineral, chemical, metallurgy, mixtures manufacture and concrete, foundry. ------------------------------------------------------------------------------------- Concrete production 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 quantity of 0,15-0,20%, it is necessary to insert superplastificators from the mass of dry substance in the quantity of 0,5-2,0% from the mass of dry concrete. When replacing superplastificators by lignosulfonates the solidity of concrete rises up to 20-25%, freeze resistance - in 3-4 times and the cost of mixtures reduces cause of adding of small amount of lignosulfonates, what is connected with their adsorbtion on the surface of hard phase. Usage of lignosulfonates reduces humidity of raw mud if conserving its flow behavior, what rises the manufacture of stove and reduces specific flow volume to the burning of clinker. With the usage of intensifier on the base of lignosulfonates the production of grinding units rises and there is an opportunity to change expensive and deficit chemical products. ------------------------------------------------------------------------------------------- Building materials production Due to its astringent, sticking and surface active properties lignosulfonates are used for producing plates: wood chips, wood-fiber and mineral-cotton. As in this production rather deficit, expensive, toxic, phenolformaldehyde, carbamide-phenolformaldehyde loams are used, mixture of modified lignosulfonate (20-30%) and loam lets to get combined binder. Thus toxication of plates, machined with additives on the base of lignosulfonates, reduces up to 50%. If we use 40 kg/m? of lignosulfonate while producing of mineral-cotton plates, we can succeed in fall-off of flow volume of toxic phenolic alcohols and therefore significal reducing of noxious emissions to the atmosphere. In addition wares are more firm and water-proof. -------------------------------------------------------------------------------------------- Keramzit production Technical lignosulfonates can be widely used as a correction additive in the keramzite gravel production. Keramzite gravel is the most popular artificial porous filler of light and construction concretes, it is got by heave of loam by means of quick burning in the rotating ovens. Correcting additives, added in formulation of loam raw, let to intensify process of keramzit formation, to rise the raw bloating, to reduce firmness and rise durability of keramzit. Additive of sodium of lignosulfonate in the quantity of 12% of mass of absolutely dry raw loam lets to get hard granules of keramzit with reduced firmness 0,380,43 g/cm?. ------------------------------------------------------------------------------------------------------ For uphole oilmen In the petroleum refining and oil producing industries lignosulfonates are used as a flotation agent and reagent for regulating of the basic parametres of mud flushes. Also they are a component of gel forming systems - low-viscous solutions with pH 2.5-3.0. Gel forming leads to redistribution 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. -------------------------------------------------------------------------------------------------------------- For diggers In minerals industry technical lignosulfonates are used as a flotation reagent - substance, letting to achieve incomplete washing of separating materials, i.e. different ore minerals and doing possible the flotation process. The fact that technical lignosulfonates are ones of less expensive flotation reagents, several thousands of them are known, advances rising the demand to these reagents in the branch. Besides of these technical lignosulfonates are used for drill well moonpool hardening. They are added in different carpets and ground bases. These constructions are strengthened by emulsified bituminous materials, liquid bituminous materials or coal tars, phenolics with the concrete or lime wich are added to lignosulfonates. --------------------------------------------------------------------------------------------------------------------- For metallurgists 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 reducing of cost price of suitable raw passes, rising of durability of core, reducing of their flowability up to 0,05-0,08%, reducing of temperature and retrenchment of time of the warm hot-setting. Lignosulfonates are used as a flotation reagent and binding reagent for briqueting close grained raw. They are widely used as a binding substances and plastificator in production of aglomeration of head, acid corrosion, hardening, etc. ------------------------------------------------------------------------------------------------ For chemists Lignosulfonates are used in pesticide production and treaters in the chemical production - as a dispergator and stabilizer in the manufacture of plants care chemical affinity. Also usage of lignosulfonates is widely spread in food and perfume industries. Vanilin, extracting from lignosulfonates and guaiacol is used for giving a specific smell. --------------------------------------------------------------------------------------------------------------------- Where and how to buy?
