General Description:
Sodium Naphthalene Sulfonate Formaldehyde Condensate (SNF) is also known as:
- Sodium Naphthalene Sulfonate Formaldehyde
- Sodium Naphthalene Formaldehyde
- Sulfonated Naphthalene Formaldehyde
- Naphthalene Sulfonate Formaldehyde Condensate (NSF)
- FDN (Fluidized Naphthalene-based Dispersant)
- PNS (Poly Naphthalene Sulfonate)
SNF is a high-purity superplasticizer widely used in the construction industry due to its exceptional performance in concrete mixtures. Its key advantages include:
- High Dispersancy - Effectively separates cement particles, preventing agglomeration.
- Low Foaming- Minimizes air entrainment, ensuring dense and durable concrete.
- High-Range Water Reduction - Significantly lowers water content (up to 20-30%) while maintaining workability.
- Strength Enhancement - Improves compressive and flexural strength of hardened concrete.
- Improved Workability - Enhances flowability, making it ideal for pumpable and self-consolidating concrete.
Technical features & adaptability:
1. Mixing amount: 0. 5-1. 0% of cementing materials, reducing rate: 20-30%
2. Keeping concrete strength intact & mixing this product, cement saving amount can reach 15-20%
3. Mixing this product 0. 7% (solid content) , slump constant increases above 10cm
4. Adapting to high strength, early strength, flowing, prefabricating & curing and prestressing force concretes etc.
5. The agent can be combined with other externally applied agents if pilot devement or laboratory experiment succeeds.
Application:
SULPHONATED NAPHTHALENE FORMALDEHYDE (SNF) has a good adaptability to various cements and it is not erodent to reinforcing bar and nonpoisonous and pollution-free. SULPHONATED NAPHTHALENE FORMALDEHYDE (SNF) has been applied to the highway, bridge, tunnel, water conservancy hydroelectric project, port, quay, skyscraper, power engineering, industrial civil building, prestressing force component and high range concrete etc.
Due to its superior performance, SNF is widely used in:
- Cast-in-place concrete - Ensures smooth placement and reduced segregation.
- Precast & prefabricated concrete - Accelerates demolding and increases production efficiency.
- Pumped concrete - Enhances pumpability over long distances.
- Steam-cured concrete - Promotes early strength development for rapid construction.
Economic & Construction Efficiency
By incorporating SNF, construction projects benefit from:
-Faster mold turnover- Reduces curing time, speeding up project timelines.
Cement savings - Lowers cement consumption without compromising strength.
Enhanced durability- Produces high-density, crack-resistant concrete.
