Product Specification

Sodium Naphthalene Formaldehyde SNF-A Na2SO4 yellow to yellow-brown powder

Naphthalene series superplasticizer (naphthalenesulfonic acid formaldehyde condensate) and some other chemical admixtures play an important role in modern concrete materials and technologies, which can improve various properties of concrete and promote the development of new concrete technologies. When used with mineral admixtures at the same time, sodium naphthalene formaldehyde can promote the utilization of industrial by-products (such as ground slag and fly ash, etc.) in the cementitious material system, which helps to save resources and protect the environment. With the continuous search for more low-cost, environmentally compatible materials and technologies, it is expected that naphthalene superplasticizer will play an important role in future concrete production.

Sodium naphthalene sulfonate (SNF) is a light yellow to yellow-brown powder, and it is easily soluble in water, ethylene glycol, diethylene glycol, slightly soluble in alcohols, and insoluble in organic solvents. In construction industry, sodium naphthalene sulphonate is widely used to prepare free-flowing and pumpable concrete mixtures. As a leading manufacturer of construction chemicals in China, Kingsun naphthalene sulfonate powder for sale has three types, they are SNF-A, SNF-B, SNF-C. And they all have different technical specifications 

Main Features of Sodium Naphthalene Sulfonate Formaldehyde

• Reduce cement dosage. If the concrete strength and slump are basically the same, cement consumption can reduce by 10-25 %.
• As a kind of high range water reducer, naphthalene sulfonate formaldehyde can improve the water reducing rate. When the water-cement ratio is constant, the initial slump of concrete can increase by more than 10 cm, and the water-reducing rate can reach 15-25%.
• The early strength of concrete. As long as using it, the strength of concrete can increase by 20-60%.
• Improving the workability of concrete. Adding SNF powder to concrete can not only save the amount of cement, improve the workability of concrete, but also speed up the construction progress.
• Good adaptability. Sodium naphthalene formaldehyde has a good adaptability with other admixtures, and can be widely used as the composition of compound admixtures, such as pumping agent, waterproofing agent, air-entraining water-reducing agent, antifreeze, etc.
• Safety. Non-irritating or radioactive, non-dangerous. It also has obvious technical effects and economic benefits.

Note:

1,  The use of porous aggregate time to add water mixing, and then add water reducing agent.

2,  When slump is large, should pay attention to the vibration time is not too long, in order to prevent bleeding and stratification.

Naphthalene superplasticizers can be divided into high concentration products (Na2SO4 content <3%), medium concentration products (Na2SO4 content 3%-10%) and low concentration products (Na2SO4 content >10%) according to the content of Na2SO4. Most naphthalene superplasticizer synthesis plants have the ability to control the content of Na2SO4 below 3%, and some advanced enterprises can even control the content of NA2SO4 below 0.4%.

Naphthalene series of water reducing agent is the largest in our country production, the most widely used highly efficient water reducing agent (accounting for more than 70% of the amount of water reducing agent), which is characterized by high water reduction rate (15% ~ 25%), no air, little effect on the setting time, relatively good adaptability with cement, can be used with other various additives compound, the price is also relatively cheap. Naphthalene superplasticizer is often used to prepare concrete with high mobility, high strength and high performance. The slump loss of concrete with naphthalene superplasticizer is faster.
