葡萄糖酸鈉是一種化合物，外觀為白色結(jié)晶或顆粒，分子式為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.
在工業(yè)上用途十分廣泛，葡萄糖酸鈉可以在建筑、紡織印染和金屬表面處理以及水處理等行業(yè)作螯合劑，鋼鐵表面清洗劑，玻瓶清洗劑，電鍍工業(yè)鋁氧著色，在混凝土行業(yè)用作緩凝劑、高能效減水劑等。
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.
工業(yè)上一般以含有葡萄糖的物質(zhì)(例如谷物)為原料，采用發(fā)酵法先由葡萄糖制得葡萄糖酸，然后再由氫氧化鈉進行中和，這樣葡萄糖酸鈉就誕生了，也可采用電解法和氧化合成。葡萄糖酸鈉國大都采用化學氧化法-次溴氧化法生產(chǎn)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.
其質(zhì)量的優(yōu)劣直接影響了工程施工的質(zhì)量。影響混凝土質(zhì)量的因素有很多，其中不同環(huán)境的溫度、成型條件，對混凝土緩凝劑的摻量也有很大的影響。葡萄糖酸鈉作為緩凝劑，佳摻量是非常重要，不容忽視的。
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，葡萄糖酸鈉們要根據(jù)不同溫度、不同類型的混凝土，科學地調(diào)配葡萄糖酸鈉外加劑的摻量。如何確定標準摻量，就需要富有經(jīng)驗的操作人員進行調(diào)配，或咨詢葡萄糖酸鈉廠家技術(shù)人員，或者葡萄糖酸鈉們的業(yè)務經(jīng)理，讓他們?yōu)槟鲈敿毜慕忉尅?/div>
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.
研究表明葡萄糖酸鈉對混凝土有明顯的輔助塑化效應，且隨著摻量的增加逐漸增強；另外，在高性能混凝土中，葡萄糖酸鈉與減水劑復配，還可提高混凝土的后期強度。葡萄糖酸鈉的適宜摻量為水泥用量的0．03％-0．07％葡萄糖酸鈉摻量超過0．1％后，由于過度緩凝使混凝土強度嚴重降低。
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.
This is only the application of sodium Gluconic acid in concrete. Sodium Gluconic acid has many other applications. Welcome to leave a message http://www.jsyjs.net Explore.
