Sodium Naphthalene Sulfonate Formaldehyde

Description:
Naphthalene superplasticizer (SNF/FDN/PNS) is a chemically synthesized non-air-entrained superplasticizer, with chemical name of sodium poly[(naphthalene formaldehyde)sulfonate]. Naphthalene superplasticizer has strong dispersion effect on cement particles and good use effect when preparing super flowing concrete as well as cast-in-situ concrete and precast members with early strength and high strength requirements. It can comprehensively improve various properties of the concrete, and is widely applied to highways, bridges, dams, harbors, tunnels, electric power, water conservancy as well as industrial and civil architecture, steam-cured and naturally-cured precast members and so on.
