Product Details

Concrete Additives Sodium Salt For Naphthalene Sulfonate Polymerized With Formaldehyde COA / MSDS

 

Name: Sodium Naphthalene Sulphonate Formaldehyde Condensate.

Name: Short for SNF, PNS, FDN
Also called: Poly Sodium Naphthalene Sulphonate;

 

Synthesis:


The product is made of naphthalene, sulfonic acid, HCHO and Alkali through sulfonation, condensation, hydrolyzation, and neutralization reaction.

 

Naphthalene formaldehyde sulphonate water reducing agent is a synthetic powder based on                 beta-sulphonate formaldehyde ondensate and reactive polymer.
It has the properties of high range water reduction, set retarding and excellent strengthening.
Elt-nsf sodium sulfate is less than 10% , suitable to middle strength or high strength
concrete where high range water reduction is desired.

 

Models:

We have 3 models: SNF-A; SNF-B; SNF-C.
ITEM SNF-A SNF-B SNF-C
Appearance Light Brown or Dark Brown Powder.
Solid Content 87~88~90~91~92~93~94~95
PH Value 7-9
Sodium Sulfate Content <5% <10% 20%
Chlorides Content <0.3% <0.4% <0.5%
Cement Flowing Rate ≥250 mm ≥240 mm ≥230 mm
Concrete Reducing Water Rate ≥14% ≥14% ≥14%

 

 

Technical features & adaptability:


1. Mixing amount: 0.5-1.0% of cementing materials, reducing rate: 20-30%
2. Keeping concrete strength intact & mixing this product, cement saving amount can reach 15-20%
3. Mixing this product 0.7% (solid content), slump constant increases above 10cm
4. Adapting to high strength, early strength, flowing, prefabricating & curing and prestressing force concretes etc.

 


Application:

 

A:Used for and widely for self-cured, vapor-cured concrete and its formulations. At the

early stage of application, extremely prominent effects are shown. As the result, the modulus and

site utilization can be drastically, the procedure of vapor cure is omitted in peak-heat summer days. Statistically 40-60 metric tons of coal will be preserved when a metric ton of the material is

consumed.

 

B.Suitable for preparation of early-strength, high-strength, high-anti-filtration and self-sealing& pumpable concrete.

 

C.Widely used in pre-cast & ready-mixed concrete, armored concrete and pre-stressed reinforced concrete in key construction projects such as dam and port construction, road building & town

planning projects and dwelling erections etc.

 

D.Compatible with Portland cement, normal Portland cement, Portland slag cement, fly-ash

cement and Portland pozzolanic cement etc.

 

 

USAGE:


A. Blending dosage at 0.5%-1.0%, 0.6% mixing dosage advised.
B. Prepare solutions as required.
C. Direct use of powder agent is allowed. Alternatively the addition of the agent is followed by water moisturization (water-cement ratio:60%).
