Product Description
Company introductionProduct descriptionTrade Name | Naphthalene superplasticizer | Chemical Name | Sodium salt of Sulfonated Naphthalene formaldehyde poly condensate |
CAS.No. | 9084-06-4 |
HS code | 3824401000 |
Towards | Concrete,textile,pesticide,rubber,oil drilling,leather and so on. |
Chemical Expression | The raw material naphthalene superplasticizer (SNF/FDN/PNS) has strong dispersion effect on cement particles and good use effect of preparing super flowing concrete as well as cast-in-situ concrete and precast members with early strength and high strength requirements, can comprehensively improve various properties of the concrete, and is widely applied to highways, bridges, dams, harbors, tunnels, electric power, water conservancy as well as industrial and civil architecture, steam-cured and naturally-cured precast members and so on. |

The influence of sodium sulfate content on concrete: 1. If the content is large, it may crystallize at low temperature which blocks pipes and valves, and reduces the water reducing capacity and strength.Because the solubility is affected by temperature change.When the outdoor temperature is below 20ºC, the solubility will drop suddenly. When the outdoor temperature is below 16ºC, the crystal of sodium sulfate is obvious.During crystallization, some effective components of naphthalene series superplasticizer will be adsorbed, which will affect the water reducing ability and strength of concrete. |
The effect of chloride ion content on reinforcement: Chloride ion is the catalyst of corroded steel bar, which will not be consumed in the process of corrosion. If the content of chloride ion in the admixture is too high, it will accelerate the corrosion of steel bar and affect the strength of concrete |
Application- Construction:
a.Widely used in precast & 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.
b. Suitable for preparation of early-strength, high-strength, high-anti-filtration and self sealing&pumpable concrete.
c. 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.
d. Compatible with Portland cement, normal Portland cement, Portland slag cement, flyash cement and Portland pozzolanic cement etc.
Others:
Because of the high dispersion force and low foaming characteristics, SNF has also been widely used in other industries as Anionic Dispersing Agent.
Dispersing agent for disperse, vat, reactive and acid dyes, textile dying, wettable pesticide,paper,electroplating, rubber, water-soluble paint, pigments,oil drilling, water treatment,carbon black, etc.
