NAPTHALENE SULFONATE

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.

Product “sodium naphthalene sulfonate” is a dispersing agent. Since it contains a sodium ion bound to a large organic molecule, it has surface active property and its structure enables the homogeneous dispersion of organic and inorganic dispersions.
This chemical product can be presented under two different trade names : “Sodium naphthalene ZWL-I” and “Powercon-100”. 
Both are presented in the form of brown powders with the same chemical properties although they are used in different sectors. 
Both are water soluble products. “Sodium naphthalene ZWL-I” is a ready-to-use superplasticizer used in concrete, in industrial and civil buildings and in miscellaneous engineering. 
It consists of an aromatic sulfonated polymer (92 %) and the dosage in the concrete might range from 0.3 % to 1.8 %.
On the other hand, “Powercon-100” consists of sodium salt of poly(naphtalenesulfonic acid) (94 %). 
Its recommended use is as super plasticizer for cement concrete, mortar and grout.

Sodium Naphthalene Sulfonate Formaldehyde (SNF)​

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 Polynaphthalenesulfonate also helps to keep the final product from separating into its oil and water components.

Sodium Polynaphthalenesulfonate and Sodium Naphthalenesulfonate are sodium salts of naphthalene sulfonic acid. 
Sodium Polynaphthalenesulfonate is used as an emulsion stabilizer, surfactant - hydrotrope, and/or surfactant - suspending agent.

Hydrotropes are surfactants which have the ability to enhance the water solubility of another surfactant. 
Prominent members of this group are short chain alkyl aryl sulfonates, sulfosuccinates, and some nonionic surfactants. Sodium Naphthalenesulfonate is used as a surfactant - hydrotrope.

Naphthalene sulfonate is a derivative of sulfonic acid with naphthalene. 
It is one of the widely used chemicals for dispersant applications across the globe. 
Naphthalene sulfonate offers a favorable cost-to-performance ratio, as it provides faster setting time when mixed with concrete. 
It is also used as a surfactant in household cleaners.


The global naphthalene sulfonate market is anticipated to expand at a rapid pace during the forecast period driven by various factors such as increase in demand from building & construction and agriculture industries. 
Naphthalene sulfonate is used as a concrete additive in the building & construction industry, as it enhances the overall performance of concrete admixtures. 
Concrete admixtures that contain naphthalene sulfonate possess superior flow and quick curing time. 
Rapid urbanization in developing countries such as China and India is anticipated to boost the demand for concrete in these countries. 
This, in turn, is projected to drive the naphthalene sulfonate market during the forecast period.

Naphthalene sulfonate also plays a vital role in the agriculture industry, as it is used as a primary dispersing agent. 
It helps active ingredients dissolve in agricultural chemicals. 
This enables chemicals to spread, thereby resulting in better performance. 
Rise in population is expected to propel the agriculture industry in Asia Pacific, thus fueling the demand for agricultural chemicals. 
This, in turn, is anticipated to drive the naphthalene sulfonate market in the region during the forecast period.

Availability of substitutes is expected to hamper the naphthalene sulfonate market during the forecast period. 
Several substitutes are available for naphthalene sulfonate. 
Major substitutes include melamine-formaldehyde condensates and polycarboxylate superplasticizer. 
Melamine-formaldehyde condensates offer superior performance as compared to naphthalene sulfonate. 
Melamine-formaldehyde condensates are available in large quantities. 
These chemicals offer good cost-to-performance ratio; therefore, these are highly preferred substitutes for naphthalene sulfonate. 
However, several concrete manufacturers are shifting toward polycarboxylate superplasticizer, which provides better performance than naphthalene sulfonate. 
It is slightly expensive than naphthalene sulfonate; however, it has better cost-to-performance ratio than naphthalene sulfonate-based superplasticizers. 
Hence, increase in competition from these substitutes is anticipated to hinder the global naphthalene sulfonate market in the near future.

A surge in the demand for this chemical from the agriculture and building and construction industry is anticipated to create ample growth opportunities for the global naphthalene sulfonate market in the near future. 
This chemical is utilized in the form of an additive in the building and construction sector. 
Once it is mixed with concrete, this chemical offers much improved flow along with faster time of setting. 
It is also utilized in the form of a surfactant in several household cleaners. 
Such multiple uses of this chemical is likely to foster growth of the global naphthalene sulfonate market in the near future. 
In the Asia Pacific region, this market is likely to expand at a considerably high speed owing to surging demand from the building and construction sector.

The construction industry is expanding at an accelerated pace due to the expanding footprint of urbanization across the globe, particularly in the developing countries. 
This development is expected to trigger the demand for ready-mix concrete, which is likely to bolster growth of the global naphthalene sulfonate market. 
Utilization of naphthalene sulfonate in concrete improves the characteristics of concrete admixtures, thereby ensuring better flow and quick spread across the surface. 
The growing demand for naphthalene sulfonate in the form of an additive in concrete admixtures is determined by the properties it posses. 
This factor is likely to play an important role in shooting demand for naphthalene sulfonate in the years to come.


Superplasticizers, also known as plasticizers or high-range water reducers (HRWR), reduce water content by 12 to 30 percent and can be added to concrete with a low-to-normal slump and water-cement ratio to make high-slump flowing concrete. 
Flowing concrete is a highly fluid but workable concrete that can be placed with little or no vibration or compaction. 
The effect of superplasticizers lasts only 30 to 60 minutes, depending on the brand and dosage rate, and is followed by a rapid loss in workability. 
As a result of the slump loss, superplasticizers are usually added to concrete at the jobsite.
