Application range of sodium gluconate

Sodium gluconate is the 1 kind of organic matter, chemical formula is C6H11NaO7, is widely used in industry, sodium gluconate can be in the construction, textile printing and dyeing and metal surface treatment and water treatment industry as efficient chelating agent, steel surface cleaning agent, glass bottle cleaning agent, electroplating industrial aluminum oxide coloring, in the concrete industry as efficient retarder, superplasticizer.

Used as a cleaning agent for steel surface: when steel surface needs to be plated with bowl, chrome, tin and nickel to adapt to special purposes, such as manufacturing tinplate, galvanized plate, surface chrome plating (electricity), etc., the billet surface needs to be strictly cleaned to firmly combine the coating with the steel surface. at this time, adding sodium gluconate to the cleaning agent will achieve very ideal effect. This has been confirmed by large companies that manufacture tinplate internationally.

Used for electroplating, film manufacturing, etc.: as the 1 kind of polyhydroxy carboxylic acid type excellent corrosion and scale inhibitor sodium gluconate, due to the above-mentioned many specific properties, such as efforts in the application of technology, will be developed into a large industry.

Application in the construction industry: Sodium gluconate can be used as an admixture in concrete. Its functions in concrete are as follows: water reducing agent and retarder. Sodium gluconate is generally used alone, but it can also be used in combination with other retarders such as carbohydrates and phosphates. Sodium gluconate is a 1 crystalline powder. It is produced under well defined and controlled conditions. This compound is chemically pure and non-corrosive. The quality is constant. These features ensure that it has reliable and reproducible results in the application.

Sodium gluconate as a retarder: sodium gluconate can significantly delay the setting time of concrete. When the dosage is below 0.15%, the logarithm of the initial setting time is proportional to the dosage, I .e. the dosage is doubled and the initial setting time is delayed to ten times, which extends the working time from few hours to several days without compromising the strength. This is an important advantage especially on hot days and when long standing times are required.

Used as a special cleaning agent for glass bottles: hundreds of millions of glass bottles in the beverage industry, food industry and brewing industry, such as soda bottles, beer bottles, milk bottles, canned bottles, soy sauce bottles, wine bottles, etc., their cleaning work is a very important thing, and the pharmaceutical formulation of cleaning agents is a difficult technical work. There is no 1 ideal medicine in China. The main problems are: the detergency is not strong, and it is easy to block the nozzle and pipeline of the bottle washing machine; The decontamination force for bottle stickers and bottleneck rust is not ideal; Trace residues after washing are not ideal for edible safety (such as phosphate residues); Washing water is discharged into public hazards (which cannot meet the standards stipulated by the state). If sodium gluconate is used as the main body in the pharmaceutical formula of the glass bottle cleaning agent, the above problems can be easily solved (in the 1980 s, large-scale tests have been done in Shanghai soda and water factory and Shanghai brewery, and there is an identification certificate). The application in this area has not yet been developed in China. If a market is formed, there is great potential.

Used as a water quality stabilizer: Because sodium gluconate has excellent corrosion and scale inhibition, 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 and other treatment agents.

Used in medicine: regulating the acid-base balance in the human body to restore the normal function of nerves, and can also be used as food additives for the same purpose.
