Snf-B Nsf-B Pns-B Fdn-B Polynaphthalene Sulfonate Chemical Building Materials

Snf-B /Nsf-B/Pns-B/Fdn-B Polynaphthalene Sulfonate Chemical Building Materials Superplasticizer

Naphthalene Sulphonate Superplasticizer Product Description:

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

Product Details And Samples:

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.

Features:

1. Main ingredient is β-naphthyl sulfonate formaldehyde condensate, sodium sulfate≤5 and 10 and 18 and 23%. 4 main types.
2. Good dispersion, water reduction and early-strength effect. It can speed up the turnover of templates and fields, accelerate construction progress and shorten the completion period. It is applicable for concrete with early-strength and high-performance requirements and other concretes that need to enhance strength and improve long term performance.
3. Increase the concrete slump and improve its liquidity, applicable for ready-mixed concrete, pumping concrete, high-liquidity concrete, grouting material, etc.
4. Without air entraining. It is applicable for all grades of concrete with steam curing condition and natural maintenance.
5. No corrosion on steel bars. It is applicable for precast concrete, cast-in-place concrete, reinforced concrete, prestressed reinforced concrete, etc. in various projects.

6. Good compatibility with portland cement, regular portland cement, portland slag cement, portland flyash cement, etc.FDN-B has good compatibility with portland cement, regular portland cement, portland slag cement, portland flyash cement, etc.

Packing, Transportation and Storage:

1. Powder pack: woven fabric bag with plastic liner. Net weight: 25kg or 50kg
2. Cautions should be taken to prevent from being torn by sharp-ended objects while packages are being transferred or delivered. When being contaminated by high humidity or moisture in case of leakage, it can be prepared in prescribed ways for further use without surrendering any effect.
3. It should be stored in a dedicated warehouse that is well-ventilated and dry. It remains effective in one year. After the expiration date, it can be used again if the testing results fall within the established range.
