Applications of Sodium Naphthalene Sulphonate Condensate
Construction:

 

 

1. 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.

 

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

 

3. 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.

 

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

 

Uses Of Sodium Dodecyl Benzene Sulfonate
 
 

Washing Effect

Sodium dodecylbenzene sulfonate is neutral, sensitive to water hardness, not easy to oxidize, strong foaming power, high detergency, easy to compound with various additives, low cost, mature synthesis process, and application It has a wide range of fields and is an excellent anionic surfactant.

 
 
 

Emulsifying and dispersing agent

Emulsifier is a substance that improves the surface tension between the various constituent phases in the emulsion to form a uniform and stable dispersion system or emulsion.

 
 
 

Antistatic agent

Any object has its own static charge, which can be negative or positive. The accumulation of static charge affects or even harms life or industrial production, and guides and eliminates the accumulated harmful charge so that it is not suitable for production.

FAQ

 

 

Q: What are the characteristics of sodium dodecylbenzene sulfonate?

A: Sodium dodecylbenzenesulfonate is a solid organic substance (light yellow) with characteristic odor at 20°C and 1013 hPa. Using the EPI Suite Mpbwin (v. 1.43) QSAR model, a Melting Point of 287.63 deg C (Weighted Value) was established.

Q: What is sodium dodecyl benzene sulfonate used for?

A: Sodium Dodecylbenzene Sulfonate is a white to light yellow sand-like solid. It is used as a detergent, in cleaning products, and in pesticides. * Sodium Dodecylbenzene Sulfonate is on the Hazardous Substance List because it is cited by DOT and EPA.

Q: What is the function of sodium dodecyl sulfate?

A: It is used in denaturing polyacrylamide gel electrophoresis for the determination of protein molecular weight. It is also used in nucleic acid extraction procedures for the disruption of cell walls and dissociation of nucleic acid:protein complexes.

Q: What is the benefit of sodium dodecyl benzene sulfonate?

A: Emulsifying and dispersing agent
As an anionic surfactant, sodium dodecylbenzene sulfonate has good surface activity and strong hydrophilicity, which can effectively reduce the tension of the oil-water interface and achieve emulsification.

Q: Is sodium dodecyl sulfate soluble in water?

A: This product is soluble in water (200 mg/ml), yielding a clear, colorless solution. SDS undergoes hydrolysis at elevated temperatures, especially in acidic medium. Prolonged heating at 40 °C or greater causes decomposition of alkyl sulfates into fatty alcohols and sodium sulfate9. 1.

Q: What is sodium naphthalene sulfonate used for?

A: Sodium Naphthalene Sulfonate is widely used for the preparation of free-flowing and pumpable concrete mixture in the construction industry. Sodium Naphthalene Sulfonate can be used as raw material for compound accelerators, anti-freezing agents, and retarders, in different construction industries.

Q: What is sodium sulfonate?

A: Sodium C14-16 olefin sulfonate is an anionic surfactant used in skin care, hair care and home good products due to its cleansing and foaming abilities.

Q: What is the function of a sulfonate?

A: Sulfonates are commonly used to confer water solubility to protein crosslinkers such as N-hydroxysulfosuccinimide (Sulfo-NHS), BS3, Sulfo-SMCC, etc.

Q: What is the mechanism of action of sulfonate?

A: Mechanism of action
Polystyrene sulfonates release sodium or calcium ions in the stomach in exchange for hydrogen ions. When the resin reaches the large intestine the hydrogen ions are exchanged for free potassium ions, and the resin is then eliminated in the feces.

Q: Is sodium polystyrene sulfonate soluble in water?

A: Solubility. Sodium polystyrene sulfonate is insoluble in water.
