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 high-efficiency water-reducing agent; finally, its cost-effectiveness is high and it can be accepted by the engineering community. Therefore, the naphthalene-based high-efficiency water-reducing agent has become the mainstream product of China's high-efficiency water-reducing agent, and it has become a widely used variety.
