Powder Sodium Naphthalene Sulfonate Formaldehyde Concrete Admixture Water Reducing Agent

Powder Sodium Naphthalene Sulfonate Formaldehyde Concrete Admixture Water Reducing Agent

Naphthalene Sulphonate Superplasticizer SNF NSF PNS FDN Product Description:

Naphthalene sulfonate sodium formaldehyde improves the workability of fresh concrete and has excellent slump retention ability. It can form unstable complexes in alkaline medium of cement products and free Ca2+, which can delay the crystallization of CH, and can also adsorb on the surface of cement hydration particles to inhibit the hydration reaction. Moreover, due to the existence of a large amount of electric charge on the surface of cement particles, the formation of flocculent structure of cement particles is prevented, the free water in flocculent aggregate is released, and the fluidity of concrete is increased. In addition, the product also has components such as air entraining and thickening, which can significantly reduce the slump loss of concrete. This series of products are non-toxic, non-flammable, no corrosion of steel reinforcement, does not affect the stability of cement, can be widely used in construction, roads, Bridges, hydraulic and underground engineering pumping construction of concrete.

Naphthalene Sulfonate Sodium Formaldehyde Matters Needing Attention:

1. In the change of cement varieties or new cement, should be done with cement compatibility test.
2. For the requirement of slow setting concrete, the setting time should be tested in advance according to the test of concrete.
3. Must be in accordance with the test proportion of the correct dosage, pouring concrete should be strictly in accordance with the construction specification operation.
4. When it is used with the admixture, its compatibility should be tested first.
5. During winter construction, in order to improve the early strength of concrete, the cement amount of concrete should be adjusted appropriately.
6. Like conventional concrete projects, maintenance must be strengthened according to construction specifications.

Naphthalene Sulfonate Sodium Formaldehyde Technical performance:

1. Naphthalene sulfonate sodium formaldehyde is suitable for concrete slump loss is too large, poor flow performance of new mixed concrete.
2. Naphthalene sulfonate sodium formaldehyde can make fresh mixed concrete has good workability, and can make concrete get better slump retention.
3. Good plasticity, can significantly prolong the transport time of the concrete and the retention time of the site, reduce the time loss.
4. In the mixing of pumping agent, this series of naphthalene sulfonate sodium formaldehyde can replace the amount of retarder according to the experimental effect.
5 naphthalene sulfonate sodium formaldehyde used in naphthalene, aliphatic, amino, poly carboxylic acid and other admixtures.
6. The performance of naphthalene sulfonate sodium formaldehyde is different according to the restriction of different regions.
