Concrete Admixture Sodium Naphthalene Formaldehyde Powder CAS 36290-04-7

Product Specification

Sodium Naphthalene Formaldehyde is used as concrete additive HS 36290-04-7

Water reduction is an important effect of surfactant on cement hydration. Water reducing agent does not affect the working condition of concrete, can reduce the unit water consumption; Or under the condition of not changing the unit water consumption, can improve the workability of concrete: or have the above two effects at the same time, and do not significantly change the gas content of the admixture. At present, the use of coagulant 10 water reducing agents are surfactants, belong to the dry anionic surfactant.

Naphthalene series superplasticizer is a condensation of naphthalene sulfonate formaldehyde which is obtained by sulfonation and condensation reaction of industrial naphthalene as raw material. This series of products have good adaptability to cement, strong dispersion effect, no retarding. Low bleed air, high water reduction rate, plastic protection early strength enhancement. The workability of newly mixed concrete can be greatly improved by using this agent. Increase slump, reduce water-cement ratio, increase concrete compactness, can adapt to various conditions of concrete construction, to ensure the performance of hardened concrete.

Scope of application

1. It is suitable for precast and cast-in-place concrete, reinforced concrete and prestressed reinforced concrete in all kinds of industrial and civil construction, water conservancy, transportation, port, municipal and other projects with C70 and below.

2, suitable for dry preparation of ordinary concrete, high strength concrete, plastic, pumped concrete and large mobility, self-leveling concrete.

3, suitable for gypsum board, coal water slurry production and use.

4, have good applicability to dry general Portland cement.

Main performance

1, This product is naphthalene sulfonate methyl condensation, divided into powder and liquid two, the appearance is brown. The product is non-toxic, odorless, non-combustible, no corrosion of steel bar.

2, water reduction enhancement effect is significant. Adding appropriate amount of this product into concrete can reduce the mixing use by 14%-23%, and can significantly improve the physical and mechanical properties of the warm set soil, and the early and late strength is significantly increased.

3, improve the workability of concrete mix, increase slump, save cement.

4. The product has less crystallization in winter and less slump loss in summer. Low dosage effect is remarkable, obviously improve workability, especially for large water cement ratio, low cement dosage concrete.

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.
