Uses
1.In the medicine field,regulation acid-base balance,in the body, to restore normal nerve,sodium plays an important role to maintain extracellular osmotic pressure and capacity,regulating acid-base Balance,play the normal neuromuscular function.Triphosphate effect in preventing lowsatisfied that the incidence of SARS.for the same purpose,it can be used for food additives.
2.It has excellent corrosion,has been widely used in water stabilizer,the nature of their excellent performance in:
(1)have obvioussynergies ,Inmolybdenum,silicon,phosphorus,tungsten,nitrite,and other formula;
(2)Corrosion rate increase with temperature increasing;
(3)strong inhibition of calcium,iron salt is very complex;
(4)as circulting cooling water corrosion inhibitor to eliminate hazards is one big advantage.
3.It can be used to make metal surface of the steel plating bowl,chromium plating,tin,nickel plating to adapt to specian purpose,its billet surface shall be subject to strict cleaning.coating on the surface of steel with a solid combination.this time its cleaning pharmacy adding sodium gluconate will achieve very good results.This has been applied and confirmed in a number of large steel companies.
4.It can be used as special cleaning agent for glass bottles:sodium gluconate as the main milk bottles of professional cleaning agent can improve the following FAQ:detergents are not strong,easy to plug the machine’s nozzle and pipe;affixed to the bottles and bottles and bottleneckis to rust staining powder is not ideal.washed trace residues of food safety is not ideal(such as phosphate);wash water emission into hazards(not meet the state standard).
5.It can be used as water-reducing admixture,retrader admixture in the construction industry:cement adding a certain amount of sodium gluconate can increase the strength and also has the function of blocking,which postpones concrete the first with the final solidification time.
It can also be used in electroplating,film manufacturing industry and has broad application pros-pects.
