Sodium Naphthalene Sulfonate Formaldehyde Based Superplasticizer CAS 9084-06-4 Powder

Sodium Naphthalene Sulfonate Formaldehyde Based Superplasticizer CAS 9084-06-4 Powder

Naphthalene Sulphonate Superplasticizer SNF NSF PNS FDN Product Description:

Sodium naphthalenesulfonate formaldehyde improves the workability of fresh concrete and has excellent slump retention ability. In the alkaline medium of cement products, it forms unstable complexes with free Ca2+, which can delay the crystallization of CH, and can also be adsorbed on the surface of cement hydration particles to inhibit the hydration reaction. Moreover, due to the large amount of electric charge on the surface of the cement particles, the formation of the cement particle flocculation structure is prevented, the free water in the flocculation aggregate is released, and the fluidity of the concrete is increased. In addition, the product also has air-entraining, thickening and other ingredients, which can significantly reduce the slump loss of concrete. This series of products is non-toxic, non-flammable, non-corrosive to steel bars, and does not affect the stability of cement. It can be widely used for pumping concrete construction in buildings, roads, bridges, hydraulics and underground projects.

Sodium Naphthalenesulfonate Formaldehyde Technical Performance:

1. Sodium naphthalenesulfonate formaldehyde is suitable for new mixed concrete with excessive slump loss and poor fluidity.
2. Sodium naphthalenesulfonate formaldehyde can make fresh concrete have good workability, and make concrete obtain better slump retention rate.
3. Good plasticity, which can significantly extend the transportation time of concrete and the residence time of the site, and reduce time loss.
4. In the mixing of pumping agents, this series of sodium naphthalenesulfonate formaldehyde can replace the amount of retarder according to the experimental effect.
5 Sodium naphthalenesulfonate formaldehyde is used in the mixture of naphthalene, aliphatic, amino, polycarboxylic acid, etc.
6. The performance of sodium naphthalenesulfonate formaldehyde varies according to the restrictions of different regions.

Sodium Naphthalenesulfonate Formaldehyde Precautions:

1. When changing the type of cement or new cement, a cement compatibility test should be done.
2. As with conventional concrete projects, the maintenance must be strengthened in accordance with the construction specifications.
3. It must be added correctly according to the test ratio, and the pouring of the concrete should be strictly in accordance with the construction specifications.
4. In winter construction, in order to improve the early strength of concrete, the cement dosage of concrete should be adjusted appropriately.
5. When used with admixtures, the compatibility should be tested first.
6. For the requirements of retarded concrete, the setting time should be tested in advance according to the test conditions of the concrete.
