Sodium Naphthalene Sulfonate(SNF) in Kingsun

Sodium naphthalene sulfonate formaldehyde(SNF/PNS/FND), also called poly naphthalene sulfonate or naphthalene superplasticizer, belongs to a type of high range water reducer, and it can be used in cement and construction industry. SNF is made of naphthalene, sulfuric acid, formaldehyde and liquid base, and undergoes a series of reactions such as sulfonation, hydrolysis, condensation and neutralization, and then is dried into a powder. By the way, Kingsun SNF superplasticizer is mainly used as concrete water reducer for construction, so it is uaually as a water reducing agent which used to formulate concrete superplasticizer, high-strength concrete, steel concrete, prestressed concrete, large formwork concrete, slip forming concrete etc. If you want to buy this product, please contact us online now.

Features of Poly Naphthalene Sulfonate(PNS)

  • High water reduction rate. The water reduction rate of naphthalene superplasticizer can be as high as 25% or more. It can effectively increase the fluidity of concrete, reduce bleeding and segregation, thereby improving the workability of concrete, facilitating construction and being easy to compact.
  • The enhancement effect is good. Under the same conditions of the amount of cementitious materials, the compressive strength of concrete with naphthalene-based superplasticizer is greatly improved compared with the reference concrete.
  • Adaptability. PNS superplasticizer is suitable for various specifications and models of cement. And it has good compatibility with other concrete admixtures, for example, it can be combined with an admixture such as a swelling agent, an air entraining agent, and an active admixture such as fly ash.
  • Good durability. The product can effectively improve the pore structure of the concrete, thereby greatly improving the durability indexes of concrete such as impermeability, carbonation resistance and freeze-thaw resistance.
  • Good safety performance. It is a non-hazardous chemical with many characteristics such as non-toxic, non-irritating and non-radioactive.
