Sodium Naphthalene Sulphonate Formaldehyde plasticizer
Sodium Naphthalene Formaldehyde is light yellow to yellow-brown powder, an anionic surfactant. sodium naphthalene formaldehyde is soluble
in water, acid, alkali and hard water, good dispersion properties. With protein and polyamide fibers have affinity.
Mainly used to coloring for vat dyes, reactive dyes, acid dyes, acid staining pad or pigment pad dyeing of the dispersing agent, as a auxiliaries for
vat dyes's powder or sizing agent. Also used staining to levelling agent and auxiliary tanning agent in leather industry.
No corrosion products on steel. Widely used in concrete works, precast, sleepers, bridges, tunnels, military engineering, hydraulic engineering,
port and airstrip, high-rise building, etc.

1, this product meets the concrete admixtures GB8076-97 national grade standards.
2, volume of cement dosage of 0.5-1%, water-reducing rate for 17-25%; early obvious intensity increase 60-95% day, three day, 28 day strength
more than 25-50%, long-term strength has greatly improved.
3, under the same cover, mix 0.7%, slump of more than 4-7 times blank, still retains plasticity.
4, save the cement in the protection of design strength cases, concrete experience migraine can be saved.
5, improved workability, and the mechanics of concrete, structural performance, increased impermeability and durability, and have good frost
6, FDN-2 water reducer widely applicable, suitable for high-strength concrete, steel reinforcement and stress of reinforced concrete, impermeability of waterproof concrete steam curing concrete and nature conservation, high fluidity concrete, preparation of freeze-thaw resistance
of concrete and so on.
Instructions for use
1, this product is blended is generally 0.5-1%, featured content 0.7%. This product may be equipped with a solution before use, can also be used
dry mixing method. Mix concrete transport vehicle, when you can also mix again.
2, the user when using the appliance for the first time or when you replace the cement, according to the specific circumstances and requirements,
do the necessary testing concrete. During the course of construction, attention FDN-2 added actual performance,summarizing experience effects
, adjustments, in order to achieve the best results. Steam curing time should also determine reasonable conservation conditions and systems.
