Potassium lignosulfonate

Sodium Lignosulphonate Used as Reinforcing Agent

Sodium Lignosulphonate ( Ceramic Body Reinforcing Agent) is one kind of modified nature lignin product. In the field of reinforcing agent for ceramic paste, the sodium lignosulphonate series products can be adopted as the main compound materials. These Sodium Lignosulphonate (HMP Ceramic Body Reinforcing Agent) attribution value is superior to other equivalent material and the economic efficiency is notable.

In the field of reinforcing agent for ceramic paste,it can enhance the strength of ceramic paste and improve the capability of molding. There will be water reducing and shortening the period for drying when mixing in the ceramic paste. It is the superior substitute goods for Carboxymethyl Cellulose .

Application of sodium lignosulphonate

Application of sodium lignosulphonate

Concrete industry:

At the concrete manufacture and dry construction,it reduces the conception of components  up to10-15% remixing of the concrete mass reduces and its solidity rises,the speed of hardeing slow down.Usage of lignosulphonate reduces humidity of raw mud if conserving its flow behaviour,which rises the manufacture of stove and reduces specific flow volume to the buring of clinker,with the usage of intensifier on the base of lignosulphonate the production of grinding units rises and there is an opportunity to change expansive and defict chemical products.

Petroleum industry:

In this area, sodium lignosulphonate is used as a flotation agent and reagent for regulating of the basic parametres of mud flushes.They are also acomponents of gel forming systerms.Gel forming leads to redistribution of fitration flows and their better regulation.Technical lignosulphonate are used for hardening of different construction types:drill well moon pool,holes,and in mine rals industry.

Building materials production:

Sodium lignosulphonate can be used in producing plates because of its astringent,sticking and surface active propertities.Because this kind of production is very expensive ,toxic,carbamide are used,mixture of  modified lignosulphonate with loam can get combined binder.Meanwhile the toxi cation of the plates can be reduced up to 50%.And in the producing of mineral-cotton plates,the products can become more firm and water-proof.

Drilling industry:

Sodium lignosulphonate can be used as a flotation reagent in minerals industry to achieve incomplete washing of separating materials. They are used for drilling well moon pool hardening and be added in different ground based in different ground bases and carpets. Sodium lignosulphonate can emulsify bituminous materials,liquid bituminous materials or coal tars,thus constructions are strengthened.

Lignosulphonate used in Asphalt industry

Crack filling composition involving quaternary ammonium salt, aliphatic amine,ammonium lignosulphonate , imidazoline, and amide.

• Water stability of an asphalt mixture can be improved by

adding 0.3% lignosulphonate fibers.

• Asphalt‐emulsifying agent containing SW sodium lignosulphonate  with

an av. mol. wt. of 200‐100,000 (sodium  lignosulfonate ,and the lignosulphonate is that broad‐leaf pine or needle‐leaf pine) has the proper HLB value, slow

demulsification speed, proper frothing ability, and strong foam stability.

• Ammonium Lignosulphonate  additive has been shown to provide a warm mix additive

that can modify the combination state of asphalt and stone material surface;

modifying the fluidity; and decrease production cost of the asphalt mixtures.

Lignosulfonate works as dispersant

Lignosulphonate use as dispersant

Dye dispersant is prepared from sulfate/sulfite pulping liquors,crosslinked with sulfite/formaldehyde, products exhibits good dispersion, property, heat-resistant stability, high temp. dispersion property, fiber staining property and azo dye reducing property.

Chemically modified lignosulphonate has been used as a dispersing agents,complexing agent, flocculent, thickener or auxiliary agents for coatings, paints or adhesives.Oil Well Drilling Muds,Coal-water slurry dispersant.

A lignosulphoante-derived material has been reported to be a good as a dispersant for soils and applications shown for cleaning and/or laundry detergent compounds.

A mixture including polycarboxylic acid, and lignosulphonate has been used for cleaning aluminum plates to prevent calcium scaling.

Lignosulphonate have been used as biodegradable and nontoxic emulsifiers or dispersants for emulsion or dispersion polymerization.

Jet printing ink was prepared including sulfonated lignin.

Lignosulphonate  use in agriculture.

•Slow-release urea is composed of 90‐99%

urea 1‐10 lignin wt.%.

Lignosulphonate is used either directly or chemically modified, as a

binder, dispersant agent for pesticides/herbicides,

emulsifier, and as a heavy metal sequestrate.

Lignosulphonate nutrient medium has been applied as an additive for

restoring vegetation on road slope and bare mountain.

• Oxidized and pulverized lignosulphoante when blended with other

chemicals has be used as a soil water retention agent in

acidic dry land or desert soil, or as a binder for fertilizer.
