APPLICATIONS
Sodium naphthalene sulfonate was employed as a detection reagent to investigate ion-pair high-performance liquid chromatographic retention behavior of copper(II)-1-oxa-4,7,10,13-tetraazacyclopentadecane complex.
Sodium naphthalene sulfonate was also employed as a stationary liquid phase for resolution of dichlorophenol isomers by GC.
Sodium naphthalene sulfonate functions as a surfactant – hydrotrope in cosmetic products, and is defined as the sodium salt of 2-naphthalene sulfonic acid that conforms to the formula.
Sodium naphthalene sulfonate is used in the following conditions and applications.
Sodium naphthalene sulfonate is used in Ready-mix concrete requiring high workability and workability retention performance.
Sodium naphthalene sulfonate is used in Industrial floors.
Sodium naphthalene sulfonate is used in Reinforced concrete slabs and floors.
Sodium naphthalene sulfonate is used in Heavily reinforced concrete elements such as column, shear wall and beam.
Sodium naphthalene sulfonate is used as a detection reagent to investigate ion-pair high-performance liquid chromatographic retention behavior of copper(II)-1-oxa-4,7,10,13-tetraazacyclopentadecane complex.
Sodium naphthalene sulfonate is also used to prepare naphthalene-1-sulfonyl chloride by reaction with phosphorousoxy chloride.
Further, Sodium naphthalene sulfonate is used as a stationary liquid phase for resolution of dichlorophenol isomers by gas chromatography.
Sodium naphthalene sulfonate superplasticizer can be applied to make flowable, strong or steam-curing concrete.
The minimum working temperature can be as low as 0 degree C.
In steam curing, concrete with superplasticizer has to be strong enough before heating.
The steam curing specification has to be pre-tested.
Sodium naphthalene sulfonate is particularly used as base material for compound admixtures.
Sodium naphthalene sulfonate possesses the features of no retarding, no air-introducing, superplastic high water-reducing and strength enhancing.
Sodium naphthalene sulfonate has low alkali content, low sulfonate, and high purity.
Sodium naphthalene sulfonate can be widely used in different concretes with less dosage and easy to use.
DESCRIPTIONS
Sodium naphthalene sulfonate based raw material designed for high water reducing in concrete admixture formulations as raw material.
Sodium naphthalene sulfonate Powder is a mild-alkaline, light brown poly-naphthalene sodium salt and a classic flux in building chemistry.
Depending on the prerequisite, Sodium naphthalene sulfonate can be used to improve the rheological and mechanical properties of concrete (workability, compressive strength and flexural strength, modulus of elasticity).
By dispersing the cement particles and breaking the cement agglomerates, for example, the use of water (reduction in the water-cement ratio of up to 30%) is reduced, which is necessary in particular in the case of high-strength concretes.
In addition, naphthalenesulfonates, e.g. influence the fluid self-leveling and the early strength.
The effect and dosage depends on the temperature, type and brand of the cement, the type of aggregates, the method of mixing and transport.
Sodium naphthalene sulfonate is a sodium salt of naphthalene sulfonic acid.
Sodium naphthalene sulfonate is a surfactant-hydrotrope used in cosmetics.
Use concentrations of Sodium naphthalene sulfonate would be typically below 2%.
In clinical studies, Sodium naphthalene sulfonate was neither an irritant (tested up to 2%), cumulative irritant (tested up to 1%), nor a sensitizer (tested up to 1%).
Sodium naphthalene sulfonate is considered safe as used in cosmetic formulations intended to be applied to the skin.
Sodium naphthalene sulfonate is a high range water reducer, high concentrate naphthalene-based superplasticizer.
Sodium naphthalene sulfonate is made of naphthalene, sulforic acid, formalin and alkali, through sulphuration, hydrolyzation, condensation and neutralization reaction. Sodium naphthalene sulfonate contains no chloride.
Thus, Sodium naphthalene sulfonate meets the requirements of chemical admixture specifications for concrete.
Advantages and Properties
•Sodium naphthalene sulfonate Increases the abrasion resistance of concrete by reducing segregation and bleeding.
•Sodium naphthalene sulfonate Provides water reduce in concrete.
•Sodium naphthalene sulfonate Enables to produce flowable concrete mixtures with low water to binder ratios.
•Sodium naphthalene sulfonate Provides high workability retention without significantly affecting the setting time of cement.
•High water-reducing rate: Sodium naphthalene sulfonate can reduce water more than 25%.
Sodium naphthalene sulfonate has features of superplasticizer, effectively increases concrete fluidity and reduces water penetration and segregation.
Therefore, Sodium naphthalene sulfonate improves concrete placement and makes concrete easy to use and compacting.
•Strengthening: Given the same amount of cement and slump requirement, this product can increase the concrete stress by 50-110%, 40-90%, 40-70% and 20-40% on day 1, 3, 7, and 28 respectively.
•High applicability: Sodium naphthalene sulfonate can be used with different variety of cement.
Sodium naphthalene sulfonate is compatible with other admixtures.
Sodium naphthalene sulfonate may be used with expanding admixture, air entraining admixture as well as fly ash for supplementary and catalystic purpose.
•Approporate setting time: Sodium naphthalene sulfonate has less effect on the initial and final setting time.
The difference in setting time generally is less than 1 hour.
•Low sodium sulfonate content: The aqueous solution has no crystals in winter, which can avoid pipeline congestions when Sodium naphthalene sulfonate applied.
•Safety: No toxic, smell and radiation; no corrosion to steel bar; no flammable and explosive material.
•Effective durability: Sodium naphthalene sulfonate can modify the structure of concrete and increase the property of anti-seepage, anti-freezing, and carbonization.
•Easy to use: Sodium naphthalene sulfonate can be added directly or used after soluted in water.
Sodium naphthalene sulfonate can be used for different working condition and concrete mixer.
Potential Acute Health Effects:
