Sodium gluconate has a wide range of usages, mainly used as a buffer for concrete admixtures, as a water stabilizer in the water treatment industry, as a cleaning agent for steel surfaces, a special cleaning agent for glass bottles, and in the food industry.
Application in the concrete field. The application benefits of Sodium gluconate in the field of construction engineering concrete are very optimistic. Its benefits are mainly reflected in prolonging the setting time of concrete, reducing the loss of concrete during slump, and increasing the strength of concrete. It is a good stabilizer in the field of water quality treatment. In the field of glass bottle washing, the washing effect is good, its superiority is very prominent, and it is a very good stabilizer.
Application in the food industry. With the development of society and economy, the food industry is currently moving toward a healthy path of diversification of dietary life, nationalization of processed foods, and low-saltness. People's requirements for seasonings are more detailed and more colorful. Sodium gluconate is a new type of functional flavoring. It can impart sour taste to food, act as a stabilizer for pH adjustment of food, improve the taste of food, and prevent protein change.
Application of sodium gluconate as concrete water reducer:
Sodium gluconate water-reducing agent is a kind of concrete superplasticizer (water-reducing agent) widely used in the market. It is also a surfactant, which can be concentrated on the surface or interface, thereby reducing the surface tension of water or Interfacial tension. When the cement is mixed with water, due to the intermolecular force between the cement particles and the electrostatic attraction, the cement slurry forms a flocculating structure, and part of the mixing water is contained in it, thereby reducing the fluidity of the mixture.
When an appropriate amount of water reducing agent is added, the fluidity of concrete can be effectively increased. The hydrophilic group in the sodium gluconate water reducing agent is very polar, so the water reducing agent adsorption film on the surface of the cement particles can form a stable solvated water film with water molecules. This water film has a good lubricating effect. , Can effectively reduce the sliding resistance between cement particles, thereby further improving the fluidity of concrete.
Application of Sodium Gluconate as Rust Inhibitor of High Performance Concrete:
Sodium gluconate was mainly used in medical and industrial cleaning applications in the past. In recent years, it has been used in concrete preparation, mainly as a retarder. And whether it can be used as a concrete rust inhibitor, there have been few studies in this area in the past. Preliminary experiments show that sodium gluconate has the potential to be used as a concrete rust inhibitor.
The appearance of sodium gluconate is white to light yellow crystalline particles. In medicine, it is often used to adjust the acid-base balance in the human body to restore the normal function of nerves. For the same purpose, it is used as a food additive. In industry, it is mainly used as a surface cleaning agent. In the application of concrete, it was mainly used as a retarder in the past to delay the hydration reaction of cement and prolong the setting time of concrete. Studies have shown that sodium gluconate has a significant retarding effect on concrete. At the same water-binder ratio, as the content of sodium gluconate increases, the setting time of concrete, both the initial setting time and the final setting time, are prolonged, and when the content of sodium gluconate exceeds the appropriate content, serious slowdown will occur. Condensed.
Chloride ions in the external environment invade the concrete in different ways, causing corrosion of steel bars and premature damage to the concrete structure and loss of durability, which seriously affects its service life. Chloride ions are a major culprit in the corrosion and destruction of reinforced concrete. Therefore, the key to the corrosion and corrosion resistance of concrete lies in the resistance to chloride ion penetration of concrete. Therefore, it is conjectured that if sodium gluconate can be used as an effective rust inhibitor, it should first increase the resistance of concrete and have a good hindering effect on the penetration of chloride ions.
Application of Sodium Gluconate in Construction Industry:
Sodium gluconate has been widely used in the construction industry, among which the use of concrete is the most common, which is a combination of cement, aggregates, admixtures and water. The production volume of concrete is relatively large. Three-quarters of concrete is aggregate, but the active ingredient in concrete is cement slurry. The properties and performance of concrete are mainly determined by the properties of cement paste. The admixture in concrete is very important, because it can accelerate the solidification, delay the solidification and other characteristics, generally use several admixtures in the cement at the same time, can be strengthened.
Sodium gluconate is such an admixture, and mixing it with concrete is of great help. Sodium gluconate mixed with it has the following functions: water reducer and retarder. Sodium gluconate is generally used alone, but it can also be used in combination with other retarders such as carbohydrates and phosphates. The production of this crystalline powder of sodium gluconate is made under constant control and reasonable prescribed conditions. This compound is chemically pure and non-corrosive. The quality is constant. These features can ensure that it has reliable and reproducible results in the application.
Application of Sodium Gluconate in Pumping Agent:
Concrete is an indispensable material in building construction. With the increase of building design height and the complexity of building design structure, higher requirements are put forward for concrete construction performance. In order to meet the constantly complex construction environment, the use of high Performance concrete pumping agent has been approved.
Pumping agents are generally composed of water reducing components, retarding components, air-entraining components, etc.The substances that can be used as retarders are divided into organic and inorganic types. The organic types are mainly lignosulfonates and polyhydroxyl Carbohydrates, humic acid type water reducing agents and hydroxycarboxylic acids, the more commonly used ones are: sodium lignosulfonate, molasses, citric acid and sodium gluconate, etc.; inorganic types are mainly borax, sodium hexametaphosphate, and tripolyphosphoric acid Sodium and zinc salts, etc.
At present, the more widely used retarders are mainly organic retarders. Among them, sodium gluconate is widely used in the production of admixtures due to its good adaptability. The combined use of sodium gluconate and water reducing agent can improve the reduction. Water rate, inhibit the hydration of cement particles, delay the setting time of cement paste, reduce the loss of concrete slump, and improve the strength of concrete. At present, most of the widely used powders are sodium gluconate powder, which is difficult to dissolve in winter production. The use of incompletely dissolved products into concrete can easily lead to a long local setting time of concrete or even non-condensation, causing engineering accidents.
