Bailin Group Co.,Ltd is a high-tech group company based on biochemical engineering with annual production capacity of 150,000metric tons of Sodium Gluconate.Our company adopts biological fermentation technology to produce sodium gluconate, introduced domestic top advanced DCS distributed control system which could achieve complete automatic control in production process.
Sodium Gluconate powder can be used as a concrete admixture in construction. It has the function of a water reducing agent and a retarder in concrete. Sodium gluconate concrete admixture is usually used alone, but it can also be used in combination with other retarders.

As a water reducing agent, sodium gluconate can make concrete mixes have better processability and increase concrete slump. By adjusting the water-cement ratio and adding sodium gluconate, the strength of the concrete structure can be enhanced. Besides, the cement content can be reduced while maintaining the original strength of the concrete. By adding sodium gluconate to the concrete, you can get the following results:
1. Improve the workability of concrete. When the water-cement ratio is constant, the addition of sodium gluconate can improve the workability of concrete.
2. Improve the strength of concrete. When the cement content remains constant and the water content of the concrete decreases. With 0.1% sodium gluconate added, the concrete water consumption can be reduced by 10%.
3. Reduce cement and water. The addition of sodium gluconate can reduce the cement content to the same proportion of water consumption. The overall water-cement ratio of the concrete remains unchanged.
Production Process of Sodium gluconate :
At present, the existing production methods of Sodium Gluconate include homogeneous chemical oxidation method, point solution oxidation method, heterogeneous catalytic oxidation method, enzyme reaction method, and fermentation method.
Sodium gluconate produced by homogeneous chemical oxidation has the advantages of high conversion rate, simple process, and low cost. However, there are many steps and many by-products, and the product is difficult to decompose, so its application is limited.
The point oxidation method is rarely used in industrial production because of its high energy consumption and difficulty in control.
The heterogeneous catalytic oxidation process is simple, the reaction is stable and easy to control, the reaction conditions are mild, and the glucose conversion rate is about 95%. The disadvantage is that after being recycled for a certain number of times, the catalytic effect is reduced, the glucose conversion rate is reduced, the reaction time is prolonged, and even the catalyst has no catalytic activity. Therefore, the catalyst must be scrapped and replaced, which correspondingly increases the catalyst consumption per unit product and makes the production cost of sodium gluconate higher.
Biological fermentation methods include fungal fermentation and bacterial fermentation processes, of which the process of preparing sodium gluconate by Aspergillus niger fermentation is more commonly used. In this process, glucose is used to obtain glucose lactone and hydrogen peroxide by simple dehydrogenation of glucose oxidase produced by Aspergillus niger, and a certain amount of NaOH solution is added to maintain a certain pH value to obtain sodium gluconate. The biological fermentation method has gradually become the main production method of sodium gluconate.
The enzymatic method is to use enzyme preparation (glucose oxidase plus catalase) to oxidize glucose to gluconic acid while adding NaOH to neutralize to produce sodium gluconate and then it is finished. The enzymatic method saves nutrients and auxiliary materials, the process is simple, the product purity is high, and the energy consumption is low. But glucose oxidase and catalase are more expensive. However, as the level of enzyme preparations increases, the activity of enzymes increases, and the cost of enzymes decreases. In the long run, the replacement of fermentation processes by enzymatic processes will become the future development trend of the industry.
