Product Introduction
  Â
Naphthalene-Based Superplasticizer is a second-generation high-efficiency water reducer and a traditional type of superplasticizer. The Naphthalene-Based Superplasticizer produced by our company offers a relatively high water-reduction rate (though slightly lower than polycarboxylate superplasticizers), significantly enhancing the strength of concrete at all ages. Strength improvement ranges from 20% to 60%.
Â
It is highly compatible with cement, non-air-entraining, and provides excellent dispersion. It greatly improves the flowability and slump of concrete while significantly reducing water consumption, enhancing the overall workability of concrete. This product is commonly used in the preparation of high-flow, high-strength, and high-performance concrete.

Products Description
High-purity raw materials are essential for producing high-quality Naphthalene-Based Superplasticizer. Our company uses high-grade β-naphthol and formaldehyde to enhance the product's dispersibility and stability.
Â
A 3-4 hour sulfonation reaction is performed to avoid insufficient reactions or the creation of by-products. Under strict control of acidity and temperature, naphthalene and formaldehyde undergo a condensation reaction to form naphthalene sulfonate formaldehyde condensate.
Â
The product's pH is then neutralized to between 7 and 9, impurities are filtered out, and it is dried and ground into high-quality Naphthalene-Based Superplasticizer.

Â
Advantages :
Â
01
Cement Reduction:
Can reduce cement consumption by 10-25% while maintaining the same concrete strength and slump.
02
Water Reduction:
Without changing the water-cement ratio, it can increase the initial concrete slump by more than 10 cm, achieving a water reduction rate of up to 25%.
03
Strength Improvement:
Significantly enhances the early and overall strength of concrete, with strength improvements ranging from 20-60%.
04
Slump Loss
Concrete slump shows a significant reduction over time, with slump loss of nearly 40% within 30 minutes.

Products Description
Â
   Naphthalene-Based Superplasticizers are available in two types based on sodium sulfate content: 5%and 17%.Â
Â
   5% Sodium Sulfate: This type provides stronger water reduction compared to the 17% variant, requiring a lower dosage and enhancing the concrete's resistance to salt and corrosion. It also offers some early strength benefits. With excellent compatibility with various types of cement, it is widely used in cast-in-place, precast, and commercial concrete, as well as in steam-cured concrete products.
Â
    17% Sodium Sulfate: This type has moderate water reduction performance but significantly enhances the early strength of concrete. Since it requires a higher dosage compared to the 5% variant, it is generally suitable for self-use or small-scale applications. In addition to all the advantages of Naphthalene-Based Superplasticizers, it also prevents alkali-aggregate reactions caused by highly reactive aggregates or humid environments, thus extending the lifespan of the concrete.
Â
Matters need Attention
Â
Use：
Â
   1. When using porous aggregate, add water and stir first, and then add water reducer.
   2. When the slump is large, it should be noted that the vibration time is not too long to prevent bleeding and stratification.
Â
package：
Â
   3.The packaging uses the inner film woven bag, which has a good isolation effect to avoid product deterioration or leakage
