What are the main uses of Sodium Gluconate?
For the use of Sodium Gluconate, I believe that customers have learned a lot. But what is its real mainstream use?
In fact, the mainstream use of Sodium Gluconate has three main areas, namely the construction industry, the medical industry and the food industry.
First, the role of Sodium Gluconate in the construction industry:
Sodium Gluconate in concrete works with water reducing agent and retarder.
Its water reduction, plasticizing, retarding effect is very significant, can greatly improve the workability of concrete, reduce slump loss, improve the late strength of concrete, as a retarder can make the initial setting time from a few hours to a few Days without loss of strength.
But also for a wide range of pumping concrete, large flow of concrete, mass concrete, high strength concrete can be used.
Second, the role of Sodium Gluconate in the medical industry:
Regulate the body's acid-base balance, to restore the normal role of nerve.
Third, the role of Sodium Gluconate in food:
For the food industry, because it can effectively prevent the occurrence of low sodium syndrome, it can be used as food additives. Sodium Gluconate and potassium gluconate have excellent taste thresholds.
Sodium Gluconate is not irritating, no bitter taste, salt quality close to salt, the threshold is much higher than other organic acid salt, salt (inorganic salt) 5 times, 2.6 times the sodium malate, 16.3 times the sodium lactate.
Sodium Gluconate and potassium gluconate in food processing used to adjust the pH, improve food flavor, instead of salt into a healthy low salt or salt (no sodium chloride) food, to enhance human health, enrich people's lives Great effect.
Cement paste, Sodium Gluconate can play a significant role, it is used as a water-reducing agent in the application. After Sodium Gluconate experiments show that nitric acid in the light and heating conditions will be decomposed, the formation of water and irritating nitrogen dioxide gas. So the reaction of dilute nitric acid should be excessive, while ensuring that the experiment in the fume hood, the final determination of dilute nitric acid and glucose molar ratio of 8.6: 1. The oxidation time and temperature have a direct effect on the conversion rate of the product. The optimum reaction conditions of the Sodium Gluconate should be heated to 100 ° C for 15-25 minutes. The optimum conversion rate can be obtained, and the generation of impurities is avoided. By optimization, Sodium Gluconate reflects the final conversion rate of up to 78%, drying and adding crystal crystals, can be light yellow crystals.
After the comparative test, the compound obtained by oxidizing glucose by dilute nitric acid is the industrial Sodium Gluconate sample, and the impurities are judged to be sodium hyaluronate. Through the cement paste test we found that the addition of sodium dodecahydrate can not enhance the retention of cement fluidity, can not delay the cement coagulation time. On the contrary, too much Sodium Gluconate does not enhance the retention of cement fluidity, can not delay the cement coagulation time; in the construction of the construction of Sodium Gluconate can not contain too much sodium dichromate impurities, otherwise it will affect the construction The flowability of the cement during the process and the setting time.
The Sodium Gluconate crystallization device comprises an evaporating device comprising a heater, a separator and a circulating pump, and further comprising: a crystal suspension tank which connects the separator through an inclined pipe, the lower end of the inclined tube is inserted into the bottom of the separator, And a buffer tank which is connected with the crystal suspension tank through a straight pipe, the lower end of the straight pipe is inserted into the lower end of the buffer tank, the height of the straight pipe is greater than 10 m, and the buffer tank is connected through a pipe Discharge pump
