10% Na2SO4 Sodium Naphthalene Sulfonate Formaldehyde OEM
Na2SO4 Content 10% Concrete Admixture Sodium Naphthalene Sulfonate Formaldehyde Customer Customized Service
Na2SO4 Content 10% Concrete Admixture Sodium Naphthalene Sulfonate Formaldehyde Customer Customized Service Product Description:
The function of the water reducing agent is to improve the workability of the concrete while keeping the mix ratio of the concrete unchanged; or to reduce the water consumption and increase the strength of the concrete while keeping the workability unchanged; or to reduce the amount of cement while keeping the strength unchanged. , Save cement and reduce costs. At the same time, the concrete is more uniform and dense after adding water reducing agent, improving a series of physical and chemical properties, such as impermeability, frost resistance, erosion resistance, etc., and improving the durability of concrete.
In the past, water-reducing agents used in hydraulic concrete were generally ordinary water-reducing agents such as pulp waste liquid, wood calcium, and molasses. The water-reducing rate was not high, generally 5%-10%. With the improvement of the quality requirements of hydraulic concrete, the quality requirements of the water reducing agent are also getting higher and higher. The naphthalene-based superplasticizers widely used in large hydropower projects such as Ertan and Three Gorges have a water reduction rate of up to 20% to 30%.
They are mainly used to prepare high-strength and high-fluid concrete or concrete that requires a significant reduction in water consumption. The superplasticizer has obvious effects on improving the efficiency of cement use, and can save about 20% of cement consumption

Chemical uses:
1. The concrete strength and slump in substantially the same, can reduce the amount of cement 10-25%.
2. In the same water-cement ratio, the concrete initial slump raise more than 10cm water reduction rate of 15-25%.
3. The concrete has a significant early strength, the reinforcing effect, the strength of improved rate of 20-60%.
4. To improve the workability of concrete, improve the physical and mechanical properties of concrete.
5. Good adaptability to various cement, and other various types of concrete admixtures compatibility is good.
6. Is particularly suitable for use in the following concrete projects: flowing concrete, plastic concrete, steam curing concrete, impervious concrete, waterproof concrete, nature conservation precast concrete, reinforced and prestressed concrete, high strength ultra-high strength concrete .
7. When the loss of a large concrete slump, slump loss of nearly half an hour to 40%.High water reducing rate (15% ~ 25%), not bleed air, small influence on the setting time, and cement adaptability is relatively good, can be used with other complex admixture of, the price is relatively cheap.
Our company can provide a variety of specifications Sodium naphthalene Sulphonate formaldehyde condensatio, waiting for you to choose, you are welcome to visit the factory and discuss cooperation.
