NAPHTHALENESULFONATE

Naphthalenesulfonates are derivatives of sulfonic acid which contain a naphthalene functional unit. A related family of compounds are the aminonaphthalenesulfonic acids.
 Of commercial importance are the alkylnaphthalene sulfonates, which are used as superplasticizers in concrete. They are produced on a large scale by condensation of
 naphthalenesulfonate or alkylnaphthalenesulfonates with formaldehyde.

Ataman Chemicals supplies a range of carefully optimised super-plasticiser raw materials to the Concrete Admixture and Drymix Industry in Europe, Middle East and Africa.

Perhaps the single most important factor influencing the explosive growth of High Performance Concrete in the past 20 years has been the development of High Range Water Reducers,
 or Superplasticisers. Technical progress in this sector has been extraordinarily rapid. Recent advances permit the concrete admixture designer to achieve excellent workability
 and remarkable slump life, whilst minimising set retardation.
High workability of concrete, resulting in easy placement without reduction in cement content
High strength concrete with normal workability but lower water content
A concrete mix with less cement but normal strength and workability
The advent of these materials made it possible for the first time to:
economically batch workable concretes with water/cement ratios of 0.3 or less,
batch Silica Fume concrete at low water/cement ratios,
achieve super-fluid, highly workable concretes without excessive set extension.
 
Ataman Kimya is capable of supply of a variety of both Calcium and Sodium PNS, with various  content of free sulphates.  The offered options provide the following advantages:

Improved product quality, with lower content of free sulphates. Crystallization of sulphate during cold weather periods can thereby be avoided.
Improved colour, important especially in the application of products for preparation of latices.
Higher activity of the product
Lower raw material consumption, by reduction of sulphuric acid and correspondingly also reduction of the neutralisation agent required.
 

The range of Super-plasticiser raw materials available from Ataman presently includes:
Poly Naphthalene Sulphonates (PNS), the Super-plasticiser "work horse" internationally,
Poly Melamine Sulphonates - a specialty product for specialised applications,
PolyCarboxylates.
In addition to concrete applications, these products find uses in other major industry sectors, for example gypsum plasterboard, dry-mix formulations and mining.

Naphthalene sulfonates can be used in a variety of applications. Ataman Chemicals provides naphthalene sulfonates with excellent wetting and dispersing properties. The Ataman portfolio 
of naphthalene sulfonates includes products which vary in foaming tendency – from medium to low. Additionally, they offer acid and base stability, hard-water tolerance and high temperature
stability.
Ataman Chemicals is an industry leader in high-performance naphthalene sulfonates. Several different series of naphthalene sulfonates are available to fit specific applications.
Naphthalene sulfonates can be utilized in water-based cleaners such as carpet shampoos, automatic dishwashing detergents, and industrial detergents, as well as in emulsion polymerization,
photographic solutions, and agricultural formulations. One grade of naphthalene sulfonate can also be used as a dispersant in many areas, which include textile chemicals, pesticide 
formulations, cements, emulsion polymerization, pigments and dyestuffs, and leather tanning.

Sodium Naphthalene Sulfonate Formaldehyde (SNF)​
August 22, 2018
Many important characteristics of concrete are influenced by the ratio of water to cementitious materials used in the mixture. By reducing the amount of water, the cement paste will have higher density, which results in higher paste quality. An increase in paste quality will yield higher compressive and flexural strength, lower permeability, increase resistance to weathering, improve the bond of concrete and reinforcement, reduce the volume change from drying and wetting, and reduce shrinkage cracking tendencies.

Superplasticizers
Superplasticizers, also known as high range water reducers, are chemical admixtures used where well-dispersed particle suspension is required. These polymers are used as dispersants 
to avoid particle segregation (gravel, coarse and fine sands), and to improve the flow characteristics (rheology) of suspensions such as in concrete applications. Their addition
 to concrete or mortar allows the reduction of the water to cement ratio, not affecting the workability of the mixture, and enables the production of self-consolidating concrete 
and high performance concrete.

This effect drastically improves the performance of the hardening fresh paste. The strength of concrete increases when the water to cement ratio decreases. However, their working
 mechanisms lack a full understanding, revealing in certain cases cement-superplasticizer incompatibilities.

Another benefit of superplasticizers is concrete early strength enhancement (50 to 75%). The initial setting time may be accelerated up to an hour earlier or retarded to be an hour 
later according to its chemical reaction. Retardation is sometimes associated with range of cement particle between 4 – 30 mm. The use of superplasticizers does not significantly 
affect surface tension of water and does not entrain a significant amount of air. The main disadvantage of superplasticizer usage is loss of workability as a result of rapid slump
 loss and incompatibility of cement and superplasticizers.

Sodium Naphthalene Sulfonate Formaldehyde (SNF)
Sodium Naphthalene Sulfonate  is a light yellow to yellowish brown powder, which is an anionic surfactant. It is widely used for the preparation of free-flowing and pumpable concrete mixture in the 
construction industry. Sodium Naphthalene Sulfonate  can be used as raw material for compound accelerators, anti-freezing agents, and retarders, in different construction industries. Its high purity
 feature makes cement particles with high low foaming, high range water reducing and strengthening. In addition, it also improves cement mobility and workability.

Sodium Naphthalene Sulfonate  is easily soluble in ethylene glycol, diethylene glycol, glycerol, and water, slightly soluble in alcohols, but it is insoluble in organic solvents. 
Furthermore, it is highly utilized in various industries such as agriculture, plastics & rubber, paper, construction, textile, oil, and others.

Applications
