葡萄糖酸钠是一种化合物，外观为白色结晶或颗粒，分子式为C20H25NaO10，易溶于水，略溶于酒精，不溶于乙醚。

Sodium Gluconic acid is a compound with white crystal or particle appearance. Its Molecular formula is C20H25NaO10. It is easily soluble in water, slightly soluble in alcohol, and insoluble in ether.

在工业上用途十分广泛，葡萄糖酸钠可以在建筑、纺织印染和金属表面处理以及水处理等行业作螯合剂，钢铁表面清洗剂，玻瓶清洗剂，电镀工业铝氧着色，在混凝土行业用作缓凝剂、高能效减水剂等。

It is widely used in industry. Sodium Gluconic acid can be used as efficient chelating agent, steel surface cleaning agent, glass bottle cleaning agent, electroplating industrial aluminum oxide coloring agent, high efficiency retarder, high efficiency water reducer, etc. in the construction, textile printing and dyeing, metal surface treatment, water treatment and other industries.

工业上一般以含有葡萄糖的物质(例如谷物)为原料，采用发酵法先由葡萄糖制得葡萄糖酸，然后再由氢氧化钠进行中和，这样葡萄糖酸钠就诞生了，也可采用电解法和氧化合成。葡萄糖酸钠国大都采用化学氧化法-次溴氧化法生产合成。

Generally, in industry, substances containing glucose (such as grains) are used as raw materials. Gluconic acid is produced from glucose by fermentation, and then neutralized by sodium hydroxide. Thus, sodium Gluconic acid is born, which can also be synthesized by electrolysis and oxidation. In most countries, sodium Gluconic acid is produced and synthesized by chemical oxidation - bromine oxidation.

其质量的优劣直接影响了工程施工的质量。影响混凝土质量的因素有很多，其中不同环境的温度、成型条件，对混凝土缓凝剂的掺量也有很大的影响。葡萄糖酸钠作为缓凝剂，佳掺量是非常重要，不容忽视的。

The quality directly affects the quality of engineering construction. There are many factors that affect the quality of concrete, among which the temperature and molding conditions of different environments also have a significant impact on the dosage of concrete retarders. As a retarder, sodium Gluconic acid is very important and should not be ignored.

在混凝土施工前，葡萄糖酸钠们要根据不同温度、不同类型的混凝土，科学地调配葡萄糖酸钠外加剂的掺量。如何确定标准掺量，就需要富有经验的操作人员进行调配，或咨询葡萄糖酸钠厂家技术人员，或者葡萄糖酸钠们的业务经理，让他们为您做详细的解释。

Before concrete construction, sodium Gluconic acid should scientifically mix the amount of sodium Gluconic acid admixture according to different temperatures and different types of concrete. How to determine the standard dosage requires experienced operators to prepare, or consult the technical personnel of sodium Gluconic acid manufacturers, or the business managers of sodium Gluconic acid manufacturers, and ask them to give you a detailed explanation.

研究表明葡萄糖酸钠对混凝土有明显的辅助塑化效应，且随着掺量的增加逐渐增强；另外，在高性能混凝土中，葡萄糖酸钠与减水剂复配，还可提高混凝土的后期强度。葡萄糖酸钠的适宜掺量为水泥用量的0．03％-0．07％葡萄糖酸钠掺量超过0．1％后，由于过度缓凝使混凝土强度严重降低。

The research shows that sodium Gluconic acid has an obvious auxiliary plasticizing effect on concrete, and it gradually increases with the increase of the dosage; In addition, in high-performance concrete, the combination of sodium Gluconic acid and superplasticizer can also improve the late strength of concrete. The appropriate dosage of sodium gluconate is 0.03% -0.07% of the cement dosage. When the dosage of sodium gluconate exceeds 0.1%, the concrete strength is severely reduced due to excessive retarding.

这只是葡萄糖酸钠再混凝土中的应用，葡萄糖酸钠在其它方面还有许多应用，欢迎各位老板一起来留言http://qxu1539600089.my3w.com探讨。
