Its important features and application effects are as follows:
1. Sodium gluconate uses water reducing agent and retarder in concrete engineering. Its water reducing, plasticizing and retarding effects are significant, which can greatly improve the workability of concrete, reduce slump loss and improve the late strength of concrete. As a retarder, the initial setting time can be extended from a few hours to several Day without loss of strength. Moreover, it can be applied in a wide range of applications, such as pumping concrete, large fluid concrete, mass concrete, and high strength concrete.
2. Sodium gluconate has excellent corrosion and scale inhibition effect, and is widely used in water quality stabilizers. Its excellent performance is as follows: (1) It has obvious coordination effect and is suitable for various kinds such as molybdenum, silicon, phosphorus, tungsten and nitrite. (2) The corrosion inhibition rate increases with increasing temperature; (3) It has strong scale inhibition ability and has strong complexing ability to calcium, magnesium and iron salts; (4) It is also used as a circulating cooling water corrosion and scale inhibitor to eliminate pollution. It has a big advantage.
3. Sodium gluconate is used as a surface cleaning agent for steel: If the surface of steel needs to be plated, chrome-plated, tin-plated or nickel-plated to suit special applications, the surface of the slab must be strictly cleaned so that the coating is firmly bonded to the steel surface. It has good anti-fouling ability and derusting ability, and can prevent the precipitation of iron, aluminum and other hydroxides in the solution during the cleaning of the electroplated metal surface.
4. Sodium gluconate is used as a special cleaning agent for glass bottles: the professional cleaning agent for glass bottles with sodium gluconate as the main formula has strong descaling power, and will not easily block the nozzles and pipelines of the bottle washing machine; The excellent ability of rust can hang water on the surface of glass bottles; the discharge of washing water meets the national standards.
Sodium gluconate
English name: Sodium Gluconate
Molecular formula: C6H11O7Na
Molecular weight: 218.4
Properties: white or light yellow crystalline powder, soluble in water, insoluble in alcohol, salty.
Uses: acid-base balance agent, water quality stabilizer, surface cleaning agent, cement admixture, food additive.
Sodium gluconate is a polyhydroxycarboxylic acid sodium, which is widely used. The situation that has been developed and applied is as follows:
1. For medicine: regulate the acid-base balance in the human body to restore the normal function of the nerve, and can also be used for food additives for the same purpose.
2. Used as a water quality stabilizer: Because sodium gluconate has excellent corrosion and scale inhibition effects, it is widely used as a water quality stabilizer.
3, used as a steel surface cleaning agent: steel surface if you need chrome plating, chrome plating, tin plating, nickel plating to adapt to special purposes, such as the manufacture of tinplate, galvanized sheet, surface chrome plating (electroplating), etc., the surface of the billet is subject to Strict cleaning, so that the coating is firmly bonded to the steel surface, when adding sodium gluconate to the cleaning agent will achieve a very good effect. This has been confirmed by large companies that manufacture tinplate internationally.
4, as a cement admixture: the addition of a certain amount of sodium gluconate in the cement can increase the plasticity and strength of the concrete, and has a retarding effect, that is, delay the initial and final solidification period of the concrete, so sodium gluconate as cement blending Agents have been widely used in important construction projects abroad, such as a large number of bridge construction projects in the Middle East. In addition, in the electroplating, film manufacturing industry, the application of sodium gluconate can be used as a blending agent in concrete. Its function in concrete is as follows: water reducing agent and retarder.
Sodium gluconate is generally used alone, but can also be used in combination with other retarders such as carbohydrates and phosphates. Sodium gluconate is a crystalline powder. It is produced under conditions that are properly regulated and controlled. This compound is chemically pure and non-corrosive. The quality is constant. These features ensure reliable and repeatable results in your application.

Sodium gluconate as a water reducing agent By adding a water reducing agent, the water to cement ratio (W/C) can be reduced. The following effects can be obtained by adding sodium gluconate:
(1) Enhancing workability When the water to cement ratio (W/C) is constant, the addition of sodium gluconate improves workability. At this time, sodium gluconate functions as a plasticizer. When the amount of sodium gluconate is less than 0.1%, the degree of improvement in workability is proportional to the amount added.
(2) Increased strength When the cement content remains unchanged, the water content in the concrete can be reduced (ie, the W/C is reduced). When the amount of sodium gluconate added is 0.1%, the amount of water added can be reduced by 10%.
(3) Reducing the cement content The water and cement content are reduced in the same proportion, and the W/C ratio remains unchanged. At this time, sodium gluconate is used as a cement reducing agent. In general, the following two aspects are important for the performance of concrete: shrinkage and heat generation.
Sodium gluconate as a retarder
Sodium gluconate can significantly retard the initial and final setting time of the concrete. When the dosage is below 0.15%, the logarithm of the initial solidification time is proportional to the amount of addition, that is, the compounding amount is doubled, and the time of initial solidification is delayed by ten times, which enables the working time to be very high. It takes a few hours to extend to a few days without compromising strength. This is an important advantage, especially on hot days and when it takes longer to place.
(1) With sodium gluconate, the W/C ratio can be lowered, which increases the strength of the concrete, which is a high-quality concrete.
(2) Large and heavy weight infusion projects are difficult to construct. Due to the addition of sodium gluconate, the improvement of the workability of the concrete and the delay of the solidification time can avoid the formation of the interface between the structures, and as a result, the structural strength can be improved.
(3) It is important to maintain the W/C ratio in hot areas to improve workability. A large amount of sodium gluconate was used in the construction of bridges in the Middle East.
(4) Adding sodium gluconate to the concrete mix can delay the setting time, which is important for long and difficult perfusion.
(5) In the modern concrete industry, premixed concrete is prepared at a central location and then transported out by a mixer truck. In this case, it is important to increase workability and initial set time.
(6) Reduce the W/C ratio to make concrete with higher strength and durability. Sodium gluconate can achieve this purpose. This is very important for high strength reinforced concrete.
(7) Precast masonry mortar must be used for a long time. Adding sodium gluconate can extend the working period.
(8) Oil well grouting is difficult to operate due to high temperature. After adding sodium gluconate, the concrete can work for several hours at 170 °C.
