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.

Conclusion |
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.
