葡萄糖酸钠是一种多羟基羧酸钠，用途十分广泛，现就已经被开发应用方面的情况介绍如下：
Sodium gluconate is a kind of sodium polyhydroxycarboxylate, which is widely used. The development and application of sodium gluconate are introduced as follows:
1、用作水质稳定剂：
1. As water quality stabilizer:
由于葡萄糖酸钠具有优异的缓蚀阻垢作用，所以被广泛用于水质稳定剂，例如作为石油化工企业循环冷却水系统，低压锅炉，内燃机冷却水系统等处理药剂。因为它有以下特异优点：
Sodium gluconate is widely used as a water quality stabilizer because of its excellent corrosion and scale inhibition effects, such as circulating cooling water system in petrochemical enterprises, low-pressure boiler, cooling water system of internal combustion engine and so on. Because it has the following special advantages:
⑴具有明显的协调效应。适用于钼、硅、磷、钨、亚硝酸盐等配方，由于协调效应影响，缓蚀效果大大提高。
(1) it has obvious coordination effect. It is suitable for molybdenum, silicon, phosphorus, tungsten, nitrite and other formulations. Due to the coordination effect, the corrosion inhibition effect is greatly improved.
⑵缓蚀率随温度升高而增加。一般缓蚀剂随着温度升高而缓蚀率下降，甚完全失去作用。但葡萄糖酸钠恰恰相反，缓蚀率在一定范围内随温度升高而提高，例如对炭钢等材质的试验中，温度从77℃F于上升到120℃F，其缓冲率平均提高5%以上。所以葡萄糖酸钠这种奇异的特性，对较高温度的体系或从低温到高温的变温体系 ，作缓蚀剂使用 是十分理想。
(2) the corrosion inhibition rate increases with the increase of temperature. With the increase of temperature, the corrosion inhibition rate of general inhibitors decreases or even completely loses its function. However, sodium gluconate is on the contrary, and the corrosion inhibition rate increases with the increase of temperature in a certain range. For example, in the test of carbon steel and other materials, the buffer ratio increases by more than 5% when the temperature rises from 77 ℃ f to 120 ℃ F. Therefore, sodium gluconate is an ideal inhibitor for high temperature system or variable temperature system from low temperature to high temperature.
⑶阻垢能力强：对钙，镁，铁盐具有很强的络合能力，所以阻垢能力很强，特别对Fe3+有极好的螯合作用，甚在全PH范围内部有作用。
(3) strong scale inhibition ability: it has strong complexation ability to calcium, magnesium and iron salts, so it has strong scale inhibition ability, especially has excellent chelating effect on Fe3 +, and even works in the whole pH range.
⑷灭公害。使用葡萄糖酸钠作为循环冷却水缓蚀阻垢剂，达到灭公害，这是目前所使用的其他缓蚀阻垢剂无法比拟的优点。
(4) eliminate public hazards. Sodium gluconate is used as corrosion and scale inhibitor of circulating cooling water to eliminate public hazards, which is an incomparable advantage of other corrosion and scale inhibitors currently used.
2、用做钢铁表面清洗剂：
2. Used as steel surface cleaning agent:
钢铁表面如需要镀钵、镀铬、镀锡、镀镍以适应特殊用途时，如制造马口铁，镀锌板，表面镀铬（电度）等，其钢坯表面均需经过严格清洗，使镀层物与钢铁表面牢固结合，这时候其清洗药剂中添加葡萄糖酸钠将会达到十分理想的效果。这一点已经被上制造马口铁的大公司所证实。
If the steel surface needs to be plated with bowl, chromium, tin or nickel to adapt to special purposes, such as tinplate, galvanized sheet and surface chromium (electric degree), the surface of steel billet shall be strictly cleaned to make the coating firmly combine with the steel surface. At this time, the addition of sodium gluconate in the cleaning agent will achieve a very ideal effect. This has been confirmed by the big tinplate companies in the world.
3、作玻璃瓶专用清洗剂：
3. As a special cleaning agent for glass bottles:
饮料工业，食品工业，酿造工业的日数以亿万计的玻璃瓶，如汽水瓶，啤酒瓶，牛奶瓶，罐头瓶，酱油瓶，酒瓶等，其清洗工作是一项十分重要的事情，清洗剂的药剂配方是一项难度较高的技术工作。目前国内尚未出现一种比较理想的药剂。主要存在问题有：去垢力不强，易堵塞洗瓶机的喷咀及管路；对瓶贴及瓶颈铁锈去染力不理想；洗后微量残留物对食用性不理想（如磷酸盐残留）；洗涤水排放成公害（不能符合规定之标准）。如在其玻璃瓶清洗剂的药剂配方中改用葡萄糖酸钠为主体，则上述问题均能迎刃而解。这方面的应用国内尚未开发，若形成市场，潜力很大。
There are hundreds of millions of glass bottles in the beverage industry, food industry and brewing industry, such as water bottles, beer bottles, milk bottles, jars, soy sauce bottles, wine bottles, etc., the cleaning work is a very important thing, and the formulation of cleaning agent is a highly difficult technical work. At present, there is no ideal medicament in China. The main problems are as follows: the cleaning power is not strong, and it is easy to block the nozzle and pipeline of bottle washing machine; the ability of removing rust from bottle stickers and bottle neck is not ideal; the micro residue after washing is not ideal for food safety (such as phosphate residue); the washing water is discharged into public hazards (which can not meet the specified standards). If sodium gluconate is used as the main body in the formulation of glass bottle cleaning agent, the above problems can be solved easily. The application in this field has not been developed in China, and if it forms a market, it will have great potential.
4、作水泥掺合剂
4. As cement admixture
水泥中添加一定数量葡萄糖酸钠后，可增加混凝土的可塑性和强度，且有阻滞作用，即推迟混凝土的更初与更终凝固时期。
Adding a certain amount of sodium gluconate into cement can increase the plasticity and strength of concrete, and has a blocking effect, that is, delaying the initial and final setting period of concrete.
