Concrete with polycarboxylates for underground part

Formaldehyde condensed naphthalene sodium sulfonate is the sodium salt of naphthalene sulfonate with polymerized formaldehyde, also called sodium naphthalene formaldehyde (SNF), poly naphthalene sulfonate formaldehyde (SNP), naphthalene sulfonate formaldehyde (NSF), naphthalene built top range water reducer, naphthalene superplasticizer.

Sodium naphthalene formaldehyde use to be a chemical synthesis of non-air-entertaining superplasticizer, that has a strong dispersion volume in cement particles, thus goods concrete with high initial and final strength. As a high range water reducing mixture, naphthalene formaldehyde sodium has been widely used in prestressing, precast, bridge, platform or any other concrete where it is desired to keep the cement / water ratio to a minimum, but achieve still the degree of workability essential to offer a Informal placement and consolidation. Sodium naphthalene sulfonate Malaysia formaldehdye can be added directly or later dissolved. It can be added during mixing or added directly to freshly mixed concrete. The recommended dosage is 0.75-1.5% by weight of cement.



1. Widely used in precast and ready-mixed concrete, reinforced concrete and prestressed concrete in key construction projects, such as dams and port construction, road construction and urban planning projects and housing erections etc.

2. suitable for the preparation of early de-force, high strength and high anti-filtration and self-sealing and concrete that can be pumped.

3. used for and widely for self-cured, steam-cured concrete and its formulations. In the initial application phase, extremely important effects are shown. As a result, module and site usage can be drastically, the steam curing process is omitted on peak heat summer days. Statistically 40-60 metric tons of coal will be conserved when a metric ton of the material use to be consumed.

4. Compatible with Portland cement, normal Portland cement, Portland slag cement, Portland fly ash cement and pozzolanic cement etc.


Because of the high dispersion strength and low foaming characteristics, SNF has also been widely used in other industries as an anionic dispersion agent.

Technical lignosulfonates are stored in closed, ventilated warehouses under conditions that prevent moisture from the product. In winter, in the event of thickening of liquid lignosulfonates, they are heated in the tank by deaf steam, i.e. Through a coil made of acid-resistant steel, lowered into the tank through the upper hatch.
