Sodium gluconate, aka: pentahydroxyhexyl sodium formula: C6H11O7Na, MW: 218.14, m.p. 206 ℃, specific rotation [α] 23 + 21.1 ° (c = 1.75, water), the solubility of 55 g / dL, 10 pH% aqueous solution is 6.2 to 7.8.
Sodium gluconate English name: Sodium Gluconate,
White or light yellow crystalline powder, soluble in water, soluble in alcohol, salty.
Main purpose: acid-base balance agent, water quality stabilizer, surface cleaners, cement admixture.
1, is used as a cement admixture:
After the cement is added sodium gluconate certain amount of plasticity and strength increase of concrete, and there is blocking, and postpone concrete initial and final period of solidification. Sodium glucose can significantly delay the start and end of setting time of concrete. In an amount of 0.15% or less, the number of initial solidification and dosed amount of time proportional to that amount doubled with addition, the solidification starting time delay to ten times, which makes it capable of operating time from less a few hours to several days without compromising on strength. Especially in the long hot days and need to put the time, this is an important advantage.
2, used in medicine:
Sodium gluconate to maintain extracellular osmotic pressure and capacity, regulating acid-base balance.
3, used as water quality stabilizer:
Because sodium gluconate has excellent corrosion and scale effect, it is widely used in water stabilizer, such as the petrochemical business cycle cooling water system, low pressure boiler, engine cooling water system treatment chemicals.
4, steel surface cleaning agent used:
If you need galvanized steel surfaces, chrome, tin, nickel to suit special purposes when manufacturing a tinplate, galvanized plate, chrome plated (plating), with its slab surface shall be subject to rigorous cleaning, the surface of the coating material and steel solid combination, this time adding its cleaning agents sodium gluconate will achieve very good results.
This product uses bio-fermentation production, without any additives.
