Polynaphthalene Sulfonate SNF NSF PNS FDN Poly Naphthalene Sulfonate​

Polynaphthalene Sulfonate SNF NSF PNS FDN 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 commercial concrete, and the performance of the water-reducing agent commercial concrete has been mastered by the majority of engineers.

The effect of excessive or insufficient mixing on the performance of commercial concrete can also be predicted; on the other hand, naphthalene The high-efficiency water reducing agent has good adaptability to 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 It is a superplasticizer; in the end, its cost-effectiveness is high and can be accepted by the engineering community.

Therefore, the naphthalene-based superplasticizer has become the mainstream product of superplasticizers and a wide range of varieties used.

Naphthalene-based water-reducing agent is the largest and most widely used high-efficiency water-reducing agent in my country (accounting for more than 70% of the amount of water-reducing agent). It is characterized by a high water-reducing rate (15%-25%) and no air-entrainment. , Has little effect on setting time, has relatively good adaptability to cement, can be used in combination with various other additives, and the price is relatively cheap.

Naphthalene-based water-reducing agents are often used to formulate high-fluidity, high-strength, and high-performance concrete.
