Sodium Gluconate 99.5% White crystalline powder CAS 527-07-1
Sodium gluconate is a kind of sodium polyhydroxy carboxylic acid, which is also known as sodium hydroxy caproate, which is white or light yellow crystalline granule or powder, easily soluble in water, slightly soluble in alcohol. The product has good effect of retardation and excellent flavor, and is widely used in construction, washing, food and medicine industry.

Application:
1.Used as a steel surface cleaner.
2.Used as cement admixture.
3.The application of sodium gluconate in the construction industry.
4.Sodium gluconate can be used as a mixture in concrete, and its function in concrete is as follows: water reducer and retarder.
5.Used as a special cleaning agent for glass bottles.
6.Used as a water stabilizer.
7. Sodium gluconate as water reducer By adding water reducing agent, the water-cement ratio (W/C) can be reduced.
8. The following effects can be obtained by adding sodium gluconate:
(1). Improve workability. When the water-cement ratio (W/C) remains unchanged, adding sodium gluconate can improve workability. At this time, sodium gluconate acts as a plasticizer. When the addition amount of sodium gluconate is below 0.1%, the degree of improvement in workability is proportional to the addition amount.
(2) Increase strength. When the cement content remains the same, the water content in the concrete can be reduced (ie, W/C is reduced). When the amount of sodium gluconate added is 0.1%, the amount of water added can be reduced by 10%.
(3) Reduce cement content. The water and cement content is reduced in the same proportion, and the W/C ratio remains unchanged. Sodium gluconate as retarder 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 is delayed to ten times, which makes the working time from very few The hours are extended to a few days without compromising strength. This is an important advantage especially in hot weather and when it needs to be placed for a long time.
Packaging and storage
1, Powder products are made of chemical fiber woven bags, lined with plastic film bags, each bag net weight (25+0.2kg), can also be customized according to customer requirements.
2, Powder products should be stored in dry and ventilated special warehouse, products such as damp caking can be crushed or dissolved into water agent use, will not affect the use effect.
