Product Description

Sodium Naphthalene Sulphonate Formaldehyde

The naphthalene-based superplasticizer is a non-air-entraining high-efficiency Water Reducing Agent synthesized by the chemical industry. Chemical name Naphthalene sulfonate formaldehyde condensate, which has strong cement particle dispersibility.

Chemical Name:
Naphthalene sulfonate formaldehyde condensate, sodium salt of polynaphthalene Sulfonic acid, naphthalene formaldehyde water reducer. β-Sodium Naphthalene Sulfonate formaldehyde condensate.


It can be used together with anionic and nonionic surface active agents. It is resistant to acid, alkali, hard water, salt, diffusing and protective colloid, and has no paint penetration and foaming. It has affinity for protein and nylon fiber and has no affinity for cotton and linen fiber.

In order to prepare large flow enthalpy, existing cast-in-place concrete and prefabricated components with early strength and high strength requirements have good effects, can comprehensively improve and improve various properties of concrete, and are widely used in roads, bridges, dams, ports. Terminals, tunnels, electricity, water and civil engineering construction, steam and nature protection prefabricated components.

Naphthalene Sulfonate Formaldehyde

The superplasticizer has a strong dispersing effect on the cement, which can greatly improve the fluidity of the cement mixture and the slump of the concrete, and at the same time greatly reduce the water consumption and significantly improve the workability of the concrete. However, some high-efficiency water reducers will accelerate the loss of concrete slump, and if the amount is too large, it will bleed. The high-efficiency water reducing agent does not change the concrete setting time substantially. When the dosage is large (over-dosing), it has a slight retarding effect, but does not delay the early strength growth of the hardened concrete.
It can greatly reduce the amount of water and significantly increase the strength of concrete at various ages. When the strength is kept constant, cement can be saved by 10% or more.
The chloride ion content is small and does not cause rust on the steel. It can enhance the impermeability, freeze-thaw resistance and corrosion resistance of concrete and improve the durability of concrete.


It is suitable for prefabricated and cast-in-place reinforced concrete in various industrial and civil construction, water conservancy, transportation, port, municipal and other projects.

Suitable for high-strength, ultra-high-strength and medium-strength concrete, as well as early-strength, moderately anti-freeze, and large-flow concrete.

Precast concrete components suitable for steam curing processes.

It is suitable for the water-reducing reinforcing component (ie, masterbatch) of various composite admixtures.

Main technical indicators:

1. Appearance: powder brown powder.

2, solid content: powder 94%

3. The liquidity of the pulp is 230mm.

4. The sodium sulfate content is 10.

5. Chloride ion content 0.5%.

Dosage range:

Powder: 0.75-1.5%; Liquid: 1.5-2.5%.


1. When the strength and slump of the crucible are basically the same, the amount of cement can be reduced by 10-25%.
2. When the water-cement ratio is constant, the initial slump of concrete is increased by more than 10cm, and the water-reducing rate can reach 15-25%.
3. There is a significant early strength and enhancement effect on cockroaches, and the strength increase is 20-60%.
4. Improve the workability of concrete and comprehensively improve the physical and mechanical properties of concrete.
5. It has good adaptability to various cements and is compatible with other types of concrete admixtures.
6. It is especially suitable for use in the following concrete projects: fluid concrete, plasticized concrete, steamed concrete, impervious concrete, waterproof concrete, natural curing precast concrete, steel and prestressed reinforced concrete, high strength ultra high strength concrete .
7. The slump of concrete has a large loss over time, and the slump loss in the half hour is nearly 40%.
