SNF-A Sulphonated Naphthalene Formaldehyde High Range Water Reducing Admixture

High Range Water Reducer Sodium Naphthalene CAS 9084-06-4 Na2SO4 Content 5% Mortar Admixtures Free Flowing Brown Powder

High Range Water Reducer Sodium Naphthalene CAS 9084-06-4 Na2SO4 Content 5% Mortar Admixtures Free Flowing Brown Powder Product Description:

Naphthalene series superplasticizer (naphthalenesulfonic acid formaldehyde condensate) and some other chemical admixtures play an important role in modern commercial concrete materials and technologies. It can improve various properties of commercial concrete and promote new commercial concrete.

The development of technology. when used together with mineral admixtures (also known as mineral admixtures), promotes the utilization of industrial by-products (such as ground slag and fly ash) in the cementitious material system, which helps to save resources and To protect the environment, under the trend of continuously searching for more low-cost, environmentally compatible materials and technologies, it can be expected that the naphthalene-based superplasticizer will play an important role in the production of commercial concrete in the future.

The Main Performance:

1. Efficient water reduction. Its water reduction rate is more than 25%. Superplasticization can effectively increase the fluidity of concrete, reduce bleeding and segregation, thereby improving the workability of concrete, making it easy to construct and compact.

2. Good enhancement effect. Under the condition of the same amount of cementitious material, the 1d, 3d, 7d and 28d compressive strength of concrete mixed with superplasticizer can be increased by 50～110%, 40～90%, 40～70% and 20～ 40%.

3. The product has strong adaptability, and the product is suitable for various specifications and types of cement. The product has good compatibility with other admixtures, and cooperates with expansion agents, air-entraining agents and other active admixtures, such as fly ash, to complement and stimulate each other.

4. Appropriate setting time. The product has little effect on the initial and final setting time of cement, and the difference in setting time is generally within 1h.

5. The product has low sodium sulfate content, and the formulated liquid will not crystallize in winter, which solves the problem of pipeline blockage caused by sodium sulfate crystallization in winter concrete manufacturing, and provides convenience for winter concrete construction; after compounding with retarding components, The concrete slump loses little over time.

6. Good product safety performance. It is non-toxic, non-irritating and radioactive, and does not contain substances that are harmful to the corrosion of steel bars; it is non-flammable and explosive, and is a non-dangerous product.

7. Good durability. The product can effectively improve the pore structure of concrete, thereby greatly improving the durability of concrete such as impermeability, carbonization and freeze-thaw resistance.

8. Easy to use. The product can be used directly, or dissolved in water first, and used as a solution admixture, which is suitable for various construction environments or the requirements of mixing models.
