Sulfonated Naphthalene Formaldehyde 9084-06-4 CAS Concrete Superplasticizer

Sulfonated Naphthalene Formaldehyde Sodium Naphthalenen Formaldehyde Product Description:

Naphthalene-based superplasticizers are generally produced using industrial naphthalene (or sometimes refined naphthalene) as raw materials. The production process is: Naphthalene becomes a powder product through sulfonation, hydrolysis, condensation, neutralization, filtration, and spray drying. The production process of naphthalene series superplasticizer is mature and the product performance is stable.

On the one hand, the product can be directly used in concrete, and the performance of the water-reducing agent concrete has been mastered by the majority of engineers. The effect of excessive or insufficient mixing on the performance of concrete can also be predicted.

on the other hand, the naphthalene-based high-efficiency reducing agent. The water agent has good adaptability with other admixtures and can be widely used as the composition of composite admixtures, such as pumping agents, waterproofing agents, air-entraining water-reducing agents, antifreeze, etc., and its composition may contain naphthalene-based high-efficiency reducing agents. Water agent.

Finally, its cost-effectiveness is relatively high and it can be accepted by the engineering community. Therefore, the naphthalene-based superplasticizer has become the mainstream product of China's superplasticizer, and it has become a widely used variety.

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.
