葡萄糖氧化制備葡萄糖酸鈉的五種方法，除酶法之外，其余四種生產工藝目前在我國均有廣泛研究。在工業化生產上，生物發酵法和多相催化氧化法應用較多。從上表我們可以很容易看出在生產成本、生產周期和生產設備要求上看，生物發酵法和多相催化氧化法具有一定的優勢，但從純度和節能降耗方面來看，酶法是五種方法中比較好的，酶法工藝的突出優越性，已經引起廣大科研工作者很大的興趣和眾多葡萄糖酸鈉企業的關注。許多學者預計，采用葡萄糖氧化酶作催化劑，用空氣氧化的方法制取葡萄糖酸鈉將是今后的發展方向。但現在由于酶制劑價格昂貴，酶法現在還沒有廣泛應用到工業化生產中。
There are five methods to prepare sodium gluconate by oxidation of glucose, and the other four methods are widely studied in China. Biological fermentation and heterogeneous catalytic oxidation are widely used in industrial production. From the above table, we can easily see that in terms of production cost, production cycle and production equipment requirements, biological fermentation method and heterogeneous catalytic oxidation method have certain advantages, but in terms of purity and energy saving, enzymatic method is the better of the five methods. The outstanding advantages of enzymatic process have aroused great interest of the majority of scientific research workers and many sodium gluconate enterprises Attention from the industry. Many scholars predict that it will be the future development direction to use glucose oxidase as catalyst and air oxidation to produce sodium gluconate. However, due to the high price of enzyme preparation, enzyme method has not been widely used in industrial production.
1.葡萄糖酸鈉的應用領域
1. Application fields of sodium gluconate
（1）用做水泥摻合劑；（2）用作水質穩定劑；（3）用作鋼鐵表面清洗劑；（4）作玻璃瓶專用清洗劑；（5）用于醫藥方面和食品添加劑方面，它主要通過調節人體內酸堿平衡，以恢復神經正常作用；（6）可用于電鍍，膠卷制造等許多工業領域。
(1) It can be used as cement admixture; (2) as water quality stabilizer; (3) as cleaning agent for steel surface; (4) as special cleaning agent for glass bottle; (5) as medicine and food additive. It can restore normal nerve function by adjusting acid-base balance in human body; (6) it can be used in many industrial fields such as electroplating, film manufacturing, etc.
2.葡萄糖酸鈉與外加劑的關系
2. The relationship between sodium gluconate and additives
外加劑一般包括減水劑、緩凝劑、速凝劑、早強劑、引氣劑、泵送劑等，而葡萄糖酸鈉是減水劑、緩凝劑、泵送劑等外加劑的主要原料。外加劑是指能有效改善混凝土某項或多項性能的一類材料。其摻量一般只占水泥量5%以下，卻能夠對混凝土的和易性、強度、耐久性或調節凝結時間及節約水泥。外加劑的廣泛應用使得混凝土技術飛速發展，技術經濟效益十分顯著，使得高強高性能混凝土的生產和應用成為現實，并解決了許多工程技術難題。
Admixtures generally include water reducer, retarder, accelerator, early strength agent, air entraining agent, pumping agent, etc., while sodium gluconate is the main raw material of water reducer, retarder, pumping agent and other admixtures. Admixture is a kind of material that can effectively improve one or more properties of concrete. Generally, its content only accounts for less than 5% of the cement content, but it can affect the workability, strength and durability of concrete or adjust the setting time and save cement. The wide application of admixtures makes the rapid development of concrete technology, and the technical and economic benefits are very significant, which makes the production and application of high strength and high performance concrete become a reality, and solves many engineering and technical problems. 
3.葡萄糖酸鈉在混凝土中的應用
3. Application of sodium gluconate in concrete
葡萄糖酸鈉近幾年來在建筑工程混凝土領域中的應用效益十分樂觀，我們知道，目前的高層及高層建筑工程建設中商品混凝土須加入外加劑，但摻入外加劑后，混凝土的坍落度損失比未摻外加劑前更加嚴重，尤其是摻加減水劑后混凝土的坍落度只能保持十幾分鐘到半小時，給施工隊造成了困難。解決這個問題已有一些研究成果，通常采用的技術路線有兩類：一類是外加劑摻加方法，另一類是復合緩凝劑。減水劑與緩凝劑復合以解決坍落損失的方法已被普遍接受，該方法的理論基礎是延緩水泥早期化產物的形成達到抑 制坍落度損失。
In recent years, the application benefit of sodium gluconate in the field of building engineering concrete is very optimistic. We know that in the current high-rise and high-rise building engineering construction, commercial concrete must be added with admixtures, but the slump loss of concrete is more serious after adding admixtures, especially after adding superplasticizer, the slump of concrete can only be maintained for more than ten minutes Half an hour, causing difficulties to the construction team. There are some research results to solve this problem. There are two kinds of technical routes commonly used: one is the method of adding additives, the other is the composite retarder. The method of compounding water reducer and retarder to solve the slump loss has been generally accepted. The theoretical basis of this method is to delay the formation of cement early products to inhibit the slump loss.
