Sodium Gluconate

Sodium gluconate is widely used in industry. Sodium gluconate can be used as a high-efficiency chelating agent in the fields of construction, textile printing and metal surface treatment and water treatment, steel surface cleaning agent, glass bottle cleaning agent, aluminum oxide coloring in electroplating industry. The concrete industry is used as a high-efficiency retarder, high-efficiency water reducer, and the like.
English alias: SODIUM GLUCONATE RE; Gluconic Acid Sodium; Sodium gluconate; sodium


Used as a steel surface cleaner:
If the steel surface needs to be chrome-plated, chrome-plated, tin-plated or nickel-plated to suit specific applications, such as making tinplate, galvanized sheet, chrome (electric), etc., the slab surface must be strictly cleaned to make the coating and steel. The surface is firmly bonded, and the addition of sodium gluconate to the detergent at this time will achieve a very desirable effect. This has been confirmed by the large companies that manufacture tinplate internationally.
Used as a cement admixture:
Adding a certain amount of sodium gluconate to the cement can increase the plasticity and strength of the concrete and has a retarding effect. That is, delaying the initial and final settling time of the concrete, for example, adding 0.15% sodium gluconate can extend the initial solidification time of the concrete by more than 10 times. For example, in high temperature season construction and large engineering operations, the delayed initial solidification time is One problem, and sodium gluconate can satisfactorily solve this problem. In addition, it is difficult to bond oil wells at high temperatures. The concrete after the addition of sodium gluconate can be plasticized in a few hours at a high temperature of 170 ° C, so that the above problems can be satisfactorily solved. Sodium gluconate has been widely used as a cement admixture in important foreign construction projects, such as a large number of bridge projects in the Middle East. It is reported that sodium cellulose sulfonate is extracted from papermaking wastewater, and its effect is incomparable with sodium gluconate.

Application of sodium gluconate in construction industry

The sodium gluconate industrial grade can be reduced by adding a water reducing agent to a water to cement ratio (W/C). By adding sodium gluconate, the following effects can be obtained: 1. Improve workability When the water to cement ratio (W/C) is constant, the addition of sodium gluconate can improve 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. Increase the 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 0.15% or less, 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.

Used as a special cleaning agent for glass bottles

In the beverage industry, the food industry, the brewing industry, hundreds of millions of glass bottles, such as soda bottles, beer bottles, milk bottles, canned bottles, soy sauce bottles, wine bottles, etc., cleaning work is very important, cleaning agents The recipe is a daunting technical task.

Used as a water stabilizer

Because sodium gluconate has excellent corrosion and scale inhibition effects, it is widely used as a water quality stabilizer, for example, as a petrochemical enterprise circulating cooling water system, low pressure boiler, internal combustion engine cooling water system, etc.

For medical use

Regulates the acid-base balance in the human body to restore normal nerve function, and can also be used for food additives for the same purpose.
