Polynaphthalene Sulfonate Water Reducer Supplier Product Description:
 

JF SODIUM NAPHTHALENE SULFONATE POWDER (SNF-A)

(Synonyms: Sodium salt of Sulfonated Naphthalene formaldehyde poly condensate in powder form)

Poly Naphthalene Sulfonate - is a High Range Water Reducing Superplasticizer (Sodium Polynaphthalene Sulfonate). Sodium Polynaphthalene Sulfonate is made in powder and liquid form: in condition of brown water soluble powder or dark-brown water solution, which has the concentration of minimum 32%.
 

 
Polynaphthalene Sulfonate Superplasticizer Application:
 
In the construction market PNS plays a very important role as an admixture in concrete known as superplasticizer. PNS plays important role in concrete, cement, gypsum, and mortar mixes. There are three different plasticizers; plasticizer, intermediate plasticizer, and superplasticizer. Each defines water reduction capacity in the concrete mix while the concrete slump is basically unchanged. Concrete plasticizers improve the rheology, mechanical, and flow properties of concrete while increasing concrete strength, promoting compaction, and providing optimium workability. In summary, plasticizers reduce the amount of water and increase the strength of the concrete. Improve the pore structure of concrete and increase its compactness. Reduce the bleeding and segregation of concrete mixture and delay the setting time of the mixture. Save cement consumption and reduce engineering cost and improve the quality of the concrete in the construction project.
 

Polynaphthalene Sulfonate Usage:

1. To provide initial workability especially with low water cement ratio.
2. To significantly improve the initial workability of site mixed concrete without increasing water demand.
3. To provide improved durability by increasing ultimate strengths and reducing concrete permeability.
4. To have high slump retention with early setting time.

 
Polynaphthalene Sulfonate Superplasticizer Typical Applications & Advantages:
1. Powerful plasticizing action with improved initial workability.
2. Reduces water cement ratio to the maximum which allows production of high strength concrete while saving cement use.
3. Improved cohesion and particle dispersion minimizes segregation and bleeding and improves pumpability.
4. Long haul and hot weather concreting.
5. Gains early strength with very high slump retention

 
Dosage:
 
The optimum dosage of Naphthalene Sulfonate Formaldehyde (SNF/ PNS) to meet specific requirements should always be determined by trials using the materials and conditions that will be experienced in use.
 
Our Suggestions As Below:
A. Blending dosage at 0.5%-1.0%, 0.6% mixing dosage advised.
B. Prepare solutions as required.
C. Direct use of powder agent is allowed. Alternatively the addition of the agent is followed by water Moisturization (water-cement ratio:60%).
