Sodium Gluconate is used in the construction industry CAS 527-07-1
Concrete is a composite material made of cement, aggregate, mixture and water. Concrete is the largest of all man-made materials. Three quarters of concrete is aggregate, but the most active component in concrete is cement slurry. The properties and properties of concrete are mainly determined by the properties of cement slurry. Mixtures in concrete can provide some beneficial effects such as accelerating solidification, delaying solidification, making air bubble, reducing water consumption and increasing plasticity. It is common to use several mixtures in cement at the same time, and the different mixtures can reinforce each other in some applications.
Sodium gluconate can be used as an admixture in concrete. Its functions in concrete are as follows: water reducing agent and retarding agent
Sodium gluconate is generally used alone, but can also be used in combination with other retarders such as carbohydrates and phosphates. Sodium gluconate is a crystalline powder. It is produced under properly regulated and controlled conditions. The compound is chemically pure and non-corrosive. The mass is constant. These characteristics guarantee reliable and repeatable results in application.

Complies with requirements of industry grade . | ||
Application:
1, used as cement mixing agent, cement adding a certain amount of sodium gluconate, can increase the plasticity and strength of concrete, and has a resistance effect, that is, delay the initial and final solidification time of concrete.
2, used in medicine, adjust the balance of acid and base in the human body, in order to restore the normal function of the nerve, based on the same purpose, used for food additives.
3, used as steel surface cleaning agent; Steel surface such as the need to port, mirror chrome plating, tin plating, sou point to adapt to the special purpose, the billet surface must pass strict cleaning, make the coating material and steel surface firmly with, then cleaning reagent adding sodium gluconate it will achieve the ideal effect.
4. Used as a special cleaning agent for glass bottles: the professional cleaning agent for glass bottles with sodium gluconate as the main formula can improve the following common problems: scaling is not strong, easy to block the bottle washing machine nozzle and pipeline, the bottle paste and bottleneck iron pin stain is not ideal: after washing trace residue is not ideal for food safety (such as sulfate): washing water discharge into a public hazard.
5 Used in electroplating, film manufacturing and many other industrial fields
6, used in the food industry, because it can effectively prevent the occurrence of low sodium syndrome, so it can be used as a food additive.
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.
