The company mainly produces high-performance polycarboxylate superplasticizer water reducer, sodium naphthalene sulfonate formaldehyde water reducer, melamine-based water reducer, gypsum retarder and defoamer as its core products, forming a complete one-stop procurement supply chain. Warmly welcome your inquiry at anytime.
SNF Superplasticizer powder is a type of concrete admixture that can reduce the amount of water used in the mixing process while maintaining the basic consistency of the concrete. Most of them are anionic surfactants, such as lignosulfonate, sodium naphthalene sulfonate formaldehyde polymer, etc. When added to the concrete mixture, SNF Superplasticizer powder has a dispersing effect on the cement particles, improving the workability of the mixture, reducing the unit water consumption, and enhancing the fluidity of the concrete mixture; or it can reduce the unit cement usage, thereby saving cement.
SNF Superplasticizer powder, it is Naphthalene-based high range water reducer, β-naphthalene sulfonic acid sodium formaldehyde condensate, is highly soluble in water, has stable physical and chemical properties and excellent performance. It is a high-performance water reducer. SNF Superplasticizer powder has the characteristics of high dispersion and low foaming, with high water reduction rate, excellent strengthening effect, strong adaptability to cement, greatly enhancing the fluidity of concrete, increasing the slump, improving workability and construction performance.
SNF Superplasticizer powder is the product obtained by sulfonation of naphthalene with sulfuric acid and subsequent condensation with formaldehyde. It belongs to an anionic type surfactant. This type of water reducer appears as a light yellow to dark brown powder depending on the product. It is easily soluble in water and has a good dispersing effect on many powder materials such as cement. The water reduction rate can reach 25%.

Product Features of SNF Superplasticizer Powder
1. At low dosage, the water-reducing property of SNF Superplasticizer powder is excellent.
2. Low alkali content, no chloride ions, and corrosion-resistant reinforcing bars;
3. Excellent fluidity and slump retention properties, with highly fluid concrete;
4. SNF Superplasticizer Powder significantly reduces concrete bleeding, avoids segregation, and results in high-strength concrete;
5. Prepare for the construction of precast and prefabricated high-flow, high-strength concrete.
Mechanism of action of Sodium Naphthalene Sulfonate Superplasticizer
Dispersion effect: After cement is mixed with water, due to the hydration process of cement particles, a double electric layer structure forms on the surface of the cement particles, resulting in the formation of a solvated water film. Moreover, the cement particles carry opposite charges, causing inter-particle attraction and forming a flocculation structure. This causes 10% to 30% of the mixed water to be encapsulated within the cement particles and unable to participate in free flow and lubrication, thereby affecting the fluidity of the concrete mixture. When a water reducer is added, because the water reducer molecules can be directionally adsorbed onto the surface of the cement particles, the surface of the cement particles carries the same charge (usually negative charge), forming an electrostatic repulsion effect, which promotes the dispersion of the cement particles, disintegrates the flocculation structure, and releases the encapsulated water, participating in the flow, thereby effectively increasing the fluidity of the concrete mixture.
