Description

The PNS(Poly Naphthalene Sulphonates) is Superplasticizer for concrete. PNS is made of naphthalene, sulfonic acid, HCHO through sulphuration, hydrolyzation, condensation, neutralization reaction with sodium hydroxide and try to PNS powder.































the functions of PNS: 















Reduce *0 to *5 percent of cement content when the strength and the slump of the concrete are basically same. 















improves the initial slump of the concrete by more than *0cm. 















improve the strength by *0 to *0 percent. 















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.

The naphthalene superplasticizer is a chemically synthesized non-air-entrained superplasticizer, with chemical name of naphthalene sulfonate formaldehyde condensate. It has strong dispersion effect on cement particles and good use effect of preparing super flowing concrete as well as cast-in-situ concrete and precast members with early strength and high strength requirements, 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.
