Description
PNS (Poly Naphthalene Sulphonates)
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.
