Main Usage:
1. Because sodium gluconate has excellent effects of corrosion and
scale proof, it is widely used as water quality stabilizer, such as
the treatment chemicals in the cooling cycle system in
petrochemical field and low pressure boilerandengine cooling water
system .
2. It is used as water stability agent and its advantages lie
in:
(1)It has obvious coordinating effect, which makes it apply to
various formulations.
Because of its influence in coordinating effect, its effect in
corrosion resistance will be more remarkable.
(2)On the contrary to the common inhibitor, the rate of corrosion
resistance will increase with the increase of temperature.
(3)The ability technology of scale inhibition requires the
combination ability of various elements, especially the chelation
to the Fe3+.
(4)As the chelation for the recycling cooling water, nothing can
compare with it and it has the function to kill the pollution
nuisance.
3. It is also used as glass bottle exclusive cleaning agent
4. It is also applied as a water reducer
