Four Applications of Sodium Lignosulphonate
Concrete industry:
At the concrete manufacture and dry construction, it reduces the conception of components up to 10-15% remixing of the concrete mass reduces and its solidity rises, the speed of hardening slows down.
Usage of lignosulphonates reduces humidity of raw mud if conserving its flow behaviour,which rises the manufacture of stove and reduces specific flow volume to the burning of clinker,
with the usage of intensifier on the base of lignosulphoantes the production of grinding units rises
and there is an opportunity to change expansive and deficit 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 a components of gel forming systerms. Gel forming
leads to redistribution of filtration flows and their better regulation. Technical lignosulphonate are used
for hardening of different construction types: drill well moon pool, holes, and in minerals industry.
Building materials production:
Sodium lignosulphoante 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 lignosulphoante with loam can get combined binder. Meanwhile the toxication 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 lignoslulphonate 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 bases and carpets. Sodium ligno can emulsify bituminous materials, liquid bituminous
materials or coal tars, thus constructions are strengthened.
