38244010 Naphthalene Based Superplasticizer Powder SNF-A Na2SO4 Content 5%

Product Specification

Sodium Naphthalene Formaldehyde SNF-A Na2SO4 content 5%

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.

USE:

1. SNF powder can be used directly, or the cement aggregate can be fully moistened with 60% mixing water before adding it.
2. When using porous aggregate, in this case, you should add water first, and then add SNF superplasticizer.
3. When the slump is large, the vibrating time should not be too long to prevent bleeding and stratification.
4. It can be used when it is prepared into a solution of the required concentration.
5. When concrete needs to be transported for a long time or a mixer truck is used, it is a good method to mix the concrete with sodium naphthalene sulfonate before use.
6. It has good adaptability with other concrete admixtures. For example, it can be widely used as a composite auxiliary agent composition, formulated into special functional auxiliary agents, such as pumping agents, waterproofing agents, air-entraining water-reducing agent additives, antifreeze, etc.
7. Prevent damp and caking. When SNF powder becomes damp and agglomerates, it must be dissolved in hot water first, and then added together with the concrete mixing water, and the moisture must be deducted.

Packaging and storage

1. Powder products are made of chemical fiber woven bags, lined with plastic film bags, each bag net weight (40±0.2kg) or (25±0.2kg) or (750±0.2kg), can also be customized according to customer requirements.

2. Powder products should be stored in dry and ventilated special warehouse, products such as damp caking can be crushed or dissolved into water agent use does not affect the actual effect.
