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.
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.
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.
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.
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.
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.jinhao360.com Explore.
