CAS 36290-04-7 Sodium Naphthalene Formaldehyde Anionic Surfactant Concrete Additive

Sodium Naphthalene Formaldehyde is used as concrete additive

Sodium naphthalene Formaldehyde(SNF) is anionic surfactants are a series of sodium salts of alkyl naphthalene sulfonic acid formaldehyde condensate.As a low molecular weight dispersant with moderate levels of sodium sulfate; it is especially useful in dispersions having low solids content. It is commonly used as dispersant, filler, leather tanning agent, building cement concrete water reducing agent, oil well cement water reducing agent .It’s often referred to as PNS or NSF or SNF.

It is important anionic surfactant in industry, widely used in printing and dyeing, leather making, cement, rubber, paint, oil field mud treatment and other industries. With the dramatic increase of synthetic fibers, as the main additives of synthetic fibers dyes, the demand for naphthalene sulfonic acid formaldehyde condensate has increased dramatically, and its position in the additive industry has become more important.

Technical Feature

1. The water reducing agent (SNF)can reduce the water consumption without affecting the normal construction of cement concrete, In the hardening process of cement concrete,there is less water to be lost,so there are fewer internal air holes in the concrete, which increases the strength of the concrete.

2. The water-reducing agent(SNF) can improve the workability of cement concrete and reduce the energy consumption of construction mixing.

3. The water-reducing agent(SNF) can reduce the amount of cement and water without reducing the performance and mechanical index of cement concrete, thus reducing the construction cost.

4. The water-reducing agent(SNF) is no adverse effect on concrete shrinkage and no corrosion effect on steel reinforcement.

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.
