Commodity:Sodium Aluminate
Other names:Aluminium sodium dioxide; SodiumaluminatecaHO; dialuminum; oxygen(-2) anion; sodiooxysodium
Molecular formula: NaAlO2
CAS No.: 1302-42-7

Property: colorless, odorless, tasteless, strongly alkaline.

Solid type: white powder or granules, hygroscopic, readily soluble in water. The aqueous solution may absorb CO2 and form aluminum hydroxide precipitate. Addition of NaOH is required to increase stability.

Liquid type: transparent slurry, stable during storage life. Prolonged stay of diluted aqueous solution may cause aluminum hydroxide precipitate.

Use:
In the construction process, it can be used as leaking stoppage agent combined with the sodium silicate.
In paper-making, this product can mix with aluminum sulfate to be a good filling agent.
In water treatment, it can be used as additive of purifier.

Sodium Hydroxide (Caustic Soda ) 98-99% Flakes.

Sodium Hydroxide, also known as lye and caustic soda, is an inorganic compound with formula NaOH. It is a white solid, a salt (ionic compound), consisting of sodium cations Na+ and hydroxide anions OHâ??. Sodium hydroxide is a highly caustic base and alkali, that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns. It is highly soluble in water and readily absorbs moisture and carbon dioxide from the air. It forms a series of hydrates NaOH·nH2O. The monohydrate NaOH·H2O cystallizes from water solutions between 12.3 and 61.8 C. The commercially available "sodium hydroxide" is often this monohydrate, and published data may refer to it instead of the anhydrous compound

Product Description
High Range Water-Reducing Admixture
Sodium Naphthalene Sulphonate Formaldehyde, Poly Naphthalene Sulfonate Formaldehyde Condensate,Concrete Admixture

Uses
Sodium Naphthalene Sulphonate Formaldehyde produces concrete with extremely workable characteristics referred to as high slump. PNS also allows concrete to be produced with very low water/cement ratios at low or normal slumps.
Sodium Naphthalene Sulphonate Formaldehyde is ideal for use in prestress, precast, bridge deck or any concrete where it is desired to keep the water/cement ratio to a minimum and still achieve the degree of workability necessary to provide easy placement and consolidation


Sodium Naphthalene Sulphonate Formaldehyde Specification:
Solid Content :96.42%
PH value :8.3


Chlorides Content :0.25%
Sodium Sulfate Content :4.4%

Addition Rates
Sodium Naphthalene Sulphonate Formaldehyde can be added directly or added in after melt. It can be added during mixing and after-mixing. The afterward approach can achieve better result. The suggested addition rate is 0.75%.
Sodium Naphthalene Sulphonate Formaldehyde Direction
Prepare solutions as required.
Direct use of powdery agent is allowed. Alternatively the addition of the agent is followed by water moisturization (water-cement ratio: 60%).
The agent can be combined with other externally applied agents if pilot development or laboratory experiment succeeds.
Sodium Naphthalene Sulphonate Formaldehyde Package, Storage & Handling
For powder: Woven fabric bag with plastic liner. Net weight: 25kg +/- 0.1 kg.

25kg in PP woven bag lined with plastic film

It is the condensation compound of formaldehyde and naphthalene sulfonic acid; is a good non-air bleed high efficiency water reducing agent. It can be used in the prestressed unit and concrete engineering of highway, port and high-rise. We also could supply the other type water reducer such as poly-carboxylate superplasticizer, sulfonated melamine-formaldehyde resin superplasticizer.
