Sodium Gluconate

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. Adding water reducing agent can reduce the water-cement ratio(W/C). The advantages of sodium gluconate uses in concrete as water reducer are as follows.

• Improve workability. When the water-cement ratio(W/C) remains the same, adding sodium gluconate can improve workability. At this time, it acts as a plasticizer. When the addition amount is below 0.1%, the degree of improvement in workability is directly proportional to the addition amount.
• Increase strength. When the cement content remains the same, the water content in the concrete can be reduced. When the amount of sodium gluconate added is 0.1%, the amount of water added can be reduced by 10%.
• Reduce cement content. Reduce the water and cement content in the same proportion, and the W/C ratio remains the same.

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, for example, as treatment agent for circulating cooling water systems in petrochemical enterprises, low-pressure boilers, and cooling water systems for internal combustion engines.

• Obvious coordination effect. It is suitable for formulas such as molybdenum, silicon, phosphorus, tungsten, nitrite, etc. Due to the coordination effect, it can greatly improve the corrosion inhibition effect.
• The corrosion inhibition rate increases with increasing temperature. Generally, corrosion inhibitors will decrease with the increase of temperature, or even lose their effect completely. However, the corrosion inhibition rate of gluconic acid sodium salt will increase with increasing temperature within a certain range. This unique characteristic of sodium gluconate as a corrosion inhibitor is ideal for higher temperature systems or systems with temperature changes from low to high temperatures.
• Strong anti-scaling ability. It has a strong complexing ability to calcium, magnesium and iron salts, so it has a strong anti-scaling ability. Especially for Fe3+, it has an excellent chelating effect.
• Eliminate public hazards. Sodium gluconate is used as a corrosion and scale inhibitor for circulating cooling water and it can eliminate public hazards at the same time. This is an advantage that other corrosion and scale inhibitors don’t have.

Used as special cleaning agent for glass bottles. A professional glass bottle cleaner with gluconic acid sodium salt 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, then 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. Gluconic acid sodium salt has the effect of masking the unique bitterness of magnesium, zinc, iron and other trace metals, especially magnesium, and is suitable to use in 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.

In image develop industry. Adding an appropriate amount of gluconic acid sodium salt powder to the developer will make the image clear and stain-free.
