Sodium gluconate, the sodium salt of gluconic acid, is white crystalline particles or powder in appearance. It has the characteristics of soluble in water, non-corrosive, non-toxic and easily biodegradable. Sodium gluconate has a wide range of uses in industrial fields. Used as a high-efficiency retarder and water reducer admixture in concrete industry. Used as a high-efficiency chelating agent in construction, textile printing and dyeing, metal surface treatment, water treatment industry and other industrial fields. It can also be used as steel surface cleaning agent, glass bottle cleaning agent, aluminum oxide coloring in electroplating industry. For sodium gluconate price? Inquiry us now.

Adding a certain amount of SG concrete admixture to the water-reducing agent can increase the water-reducing rate, improve the plasticization of the water-reducing agent, and increase the strength of concrete.
Without adding other retarders, adding a small amount of sodium gluconate to the concrete can achieve the effect of retarding pumping, thereby solving the problems of difficulty in construction or mass concrete construction in high temperature and hot seasons. It won’t affect the concrete performance strength.
Using SG concrete admixture alone or in combination with other types of admixtures to produce water reducing admixture, concrete retarder admixture and pumping agents can improve concrete performance, reduce costs, and have significant economic effects.
After adding a certain amount of sodium gluconate powder to cement, it can increase the plasticity and strength of concrete. It also has a retarding effect, that is, delaying the initial and final solidification period of concrete. Usually used as a water reducer and concrete retarder admixture in concrete.
Used as water reducing admixture. By adding water reducing agent, the water-cement ratio(W/C) can be reduced. The advantages of sodium gluconate uses in concrete as water reducer are as follows.
Used as concrete retarder admixture. Sodium gluconate can significantly delay the setting time of concrete. When the dosage is less than 0.15%, the logarithm of the initial setting time is directly proportional to the dosage. That is, the dosage is doubled, and the initial setting time can be delayed to ten times, which makes the working time extend from a few hours to a few days without compromising the strength. Especially in hot weather and when it needs to be placed for a long time.
With excellent corrosion and scale inhibition effects, SG is widely used as a water quality stabilizer, such as, used as treatment agent for circulating cooling water systems in petrochemical enterprises, low-pressure boilers, and cooling water systems for internal combustion engines.
Used as special cleaning agent for glass bottles. A professional glass bottle cleaner with sodium gluconate as the main formula can improve the following common problems. The detergency isn’t strong and it is easy to block the nozzle and pipeline of the bottle washer. Unsatisfactory de-staining power to bottle stickers and bottle neck rust. Trace residues after washing affect the safety of food, such as phosphate residues. The discharge of washing water causes pollution.
Used as steel surface cleaner. If the steel surface needs to be plated, chrome-plated, tin-plated, nickel-plated for special purposes, the surface of the billet must be strictly cleaned to make the plating material and the steel surface firmly bonded. Adding sodium gluconate to the cleaning agent will achieve desired results.
Sodium gluconate food grade is non-irritating, no bitter and astrigent. Mask the bitter taste of magnesium. Sodium gluconate has the effect of masking the unique bitterness of magnesium, zinc, iron and other trace metals, especially magnesium, and is suitable to be added to beverages and health foods.
Replace table salt for food processing. Sodium gluconate can replace table salt in food processing to improve characteristics, adjust fermentation, and endow various functions such as food preservation and dehydration. Sodium in sodium gluconate only accounts for 10.05% of the molecular weight, while sodium in table salt accounts for 39.3% of the molecular weight. For the same amount of sodium gluconate and table salt, the amount of sodium in the former is only 1/4 of that of the latter. Therefore, sodium gluconate can completely replace table salt to process salt-reduced or even salt-free foods, and play a great role in improving human health.
It plays an important role in maintaining extracellular osmotic pressure and capacity, regulating acid-base balance, and exerting the normal function of neuromuscular. It can effectively prevent the occurrence of low sodium syndrome.
Used as an electroplating additive in the electroplating industry. It can be operated at a higher temperature and can be directly plated to obtain a bright gold coating without polishing and chrome plating. It has good rust removal performance.
Used in image develop industry. Adding an appropriate amount of sodium gluconate to the developer will make the image clear and stain-free.
