1. Biological fermentation. The method includes fungal fermentation and bacterial fermentation, as well as a fixed cell fermentation process, in which the more commonly used is the Aspergillus niger fermenting technology grade Sodium Gluconate process. The method has the characteristics of fast fermentation speed, easy control of fermentation process and easy extraction of product, but it also appears that the color of the product is not easy to control and the degree of sterility is high.

2. Homogeneous chemical oxidation. Crystalline glucose is dissolved by adding water to the catalyst, controlling the temperature, dropping the sodium hypochlorite solution, and dropping the ionic membrane liquid base to control the pH value of the reaction system so that the equilibrium moves to the direction of the formation of the Tech Grade Sodium Gluconate. The use of this method to produce the Tech Grade Sodium Gluconate has the advantages of high conversion rate, simple process and low cost, but its intermediate step is more than the byproduct, the product is difficult to separate, so it is limited in application.

3. Electrolytic oxidation method. The method is to add a certain concentration of glucose solution in the electrolytic cell, then add the appropriate electrolyte, at a certain temperature, a certain current density constant current electrolysis. The determination of its industrial parameters varies with the addition of electrolyte. Although the electrolytic oxidation method to overcome the biological fermentation and homogeneous chemical oxidation of certain shortcomings, but in industrial production energy consumption, easy to control, so the industrial production is rarely used.

4. Heterogeneous catalytic oxidation. Prepare a certain amount of glucose solution added to the four-necked flask, weighed the amount of catalyst added to the flask, constant temperature. The process is simple, smooth response, easy to control, mild reaction conditions, the glucose conversion rate of 95%.
In ordinary concrete projects, the standard usage is generally between 0.05 and 1.0, and in general, more than 0.7 of the use of concrete in the performance of the other have a certain degree of weakness. 20 ℃ temperature conditions, play a retarding effect for several hours to use the amount of 0.075; at 20 ℃ temperature, want to reach more hours, the proposed use of 0.15; and at room temperature 20 ℃, want To achieve the effect of retardation within 2 days, the standard amount of mortar concrete admixture is 0.25.

In high temperature conditions, similar to the well operation, similar to 170 ℃ high temperature, concrete is more likely to solidify, and more prone to cracks and other issues, so the need to use more in order to achieve the desired retardation effect, generally in this case The use of 1.00, and the configuration of super-strength plasticized concrete required to use the amount of 1.00. Daily life in the normal requirements of the use of plastic surgery is generally 0.05, basically we can achieve our basic construction of concrete retarder requirements. However, the specific circumstances of the specific use, in the special needs of the environment, we must use the special requirements of the use of the.

Industry Grade Sodium Gluconate as a concrete additive, in the current market applications have great advantages, especially in the summer, the application of the product more, the market demand is greater, the price will be affected by the impact of demand fluctuations, In this article we briefly understand the relevant factors on the technical level of sodium gluconate prices.
First of all, the impact of the market demand, the summer demand for Tech Grade Sodium Gluconate is relatively more than the demand for winter and other seasons to be more, so the price may rise above the market supply will also be a great floating, Construction season, the demand for Tech Grade Sodium Gluconate increased, the various chemical companies in the summer orders have increased, the competitive pressure also will become larger.
And then the impact of summer temperatures, high temperature weather will increase the demand for concrete admixtures to speed up the cement hydration reaction time, the cement hydration reaction peak in advance, which caused the cement can not be completed within the specified time construction, Reaction to extend or advance will give us a direct impact on the construction, so the requirements of concrete admixtures will be more stringent.
