A variety of production technologies for Sodium Gluconate
    Common Sodium Gluconate production methods are electrolytic oxidation, bio-fermentation, heterogeneous catalytic oxidation and homogeneous oxidation. They have their own advantages and disadvantages, the following Xiaobian give you about.
    Electrolytic oxidation method is in the electrolytic cell by adding Sodium Gluconate solution, adding the appropriate electrolyte, in the appropriate temperature and current density constant current point solution. Advantages: to overcome the shortcomings of bio-fermentation and homogeneous chemical oxidation. Disadvantages: energy consumption, easy to control. Rarely used in industrial production.
    Biological fermentation: divided into fungal fermentation and bacterial fermentation, fixed cell fermentation. Industry is often used in the production of Aspergillus niger fermented public welfare. Advantages: faster, easy to control the process, a product extraction. Disadvantages: the product is not easy to control the color, the production process aseptic demanding.
    Heterogeneous catalytic oxidation method: is to add a good solution of Sodium Gluconate into the flask, add the right amount of catalyst to keep the temperature, the solution into the air, the constant concentration of sodium hydroxide at low concentrations easy to maintain the PH value, after the solution after the solution Treated with Sodium Gluconate. Advantages: simple, smooth response, easy to control, high conversion rate. Disadvantages: the catalyst used a certain number of times, the catalytic efficiency decreased, so that the conversion rate decreased.
   Sodium Gluconate production technology there are many, industrial production technology is one of them, is also more common. It is usually used in the industry to use glucose-containing substances (such as cereals) as raw materials, the use of fermentation by the first glucose gluconic acid, and then by sodium hydroxide to neutralize, you can get Sodium Gluconate, electrolysis can also be used and oxidation synthesis. Most of our use of chemical oxidation - sub-bromine oxidation production synthesis. According to the type of fermentation enzymes used, the fermentation method can be divided into two clocks, one is the enzyme, another acid, the latter rule by virtue of glucose dehydrogenation to form lactone, and then the ester decomposition.
 Because Sodium Gluconate itself uses a wide range, it is necessary to pay attention to whether these problems can be used to ensure effective control, so that when the control of the effect can be more stable to do these conditions. For example, Sodium Gluconate has the role of maintaining water, which is more obvious in the application of cigarettes, generally in the tobacco by adding a certain amount of Sodium Gluconate, can effectively prevent the loss of water in tobacco, in use is not easy to damage the fall The
    Therefore, when using Sodium Gluconate or pay attention from its chemical properties, can produce a good effect, but in this process should pay attention to the use of its conditions. Some storage environment will have a negative impact on its performance, which is the need to pay attention to the place.
    Sodium Gluconate in the industry is widely used, we in the construction, textile, printing and dyeing industries can see its shadow, it can be said that Sodium Gluconate is a very important chemical raw materials. Since it is universal and important, then we need to understand its related knowledge. Today we mainly talk about the important role of Sodium Gluconate in concrete.
When a certain amount of Sodium Gluconate is added to the cement, it will have a very good effect on the concrete, not only to increase the plasticity and strength of the concrete, but also have a blocking effect, that is, to delay the initial and final solidification period of concrete. For example, the addition of 0.15% Sodium Gluconate can extend the initial settling time of the concrete by more than 10 times, that is, to extend the plastic's plastic time from a few hours to a few days without affecting its fastness. Plasticity and retardation The initial setting time is a very important problem in concrete operations. For example, in the high temperature season construction and large engineering operations, it is a difficult problem to delay the initial setting time. Sodium Gluconate can solve this problem satisfactorily. In addition, high temperature bonding oil wells is more difficult, added Sodium Gluconate concrete at 170 ℃ high temperature, within a few hours plastic, it can also satisfactorily solve the problem.
