Purity: 98% Product Grade: a product density: 1.45 (g / cm3)
English name: Sodium gluconate Chinese name: sodium gluconate Molecular formula: C6H11NaO7 Characteristics: white or yellow crystalline particles or powder. White to brown crystalline granules or powder, easily soluble in water, slightly soluble in alcohol, insoluble in ether. Quality Standard: FAO / WHO Packing: 25KG use: 1, a water reducing agent sodium gluconate By adding a reducing agent, the water to cement ratio (W / C) can be reduced. Sodium gluconate can be obtained by adding the following effects: 1, increase workability at water cement ratio (W / C) remain unchanged, added sodium gluconate can enhance workability. At this time, from the sodium gluconate is a plasticizer. At 0.1% or less of sodium gluconate increase the amount of improvement is proportional to the degree and amount of work. 2, while enhancing the strength of the cement content of the concrete remains constant and the water content can be reduced (i.e., W / C decreased). When the amount of sodium gluconate is 0.1%, the amount of water can be reduced by 10%. 3, reducing the amount of water and cement with the cement in order to reduce the proportion of the content, W / C ratio remains unchanged. At this time, as a cement, sodium glucose reduction agent. Under normal circumstances, these two aspects of the performance of concrete that is very important: contraction and generate heat. 2, as the retarder Sodium gluconate Sodium gluconate can significantly delay the start and end of the setting time of concrete. In an amount of 0.15% or less, the number of initial solidification and with addition of an 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 3, used glass bottles for cleaning agents: Beverage industry, food industry, industrial brewing for several days to hundreds of millions of glass bottles, such as soda bottles, beer bottles, milk bottles, cans bottles, soy sauce bottles, wine bottles, etc., the cleaning work is a very important thing, cleaning pharmaceutical formulations agent is a higher degree of difficulty of the technical work. At present, it has not yet appeared an ideal agent. The main problems are: detergent is not strong, easy to plug the bottle washer nozzle and pipe; rust on the bottle labels and bottlenecks to dye force is not ideal; washed trace residues on food safety is not ideal (such as phosphate the residue); wash water discharged into public nuisance (can not comply with the provisions of the national standard). Such as the use of glucose, sodium acid in its pharmaceutical formulations for glass cleaning agent body, the above problems can be solved. (The eighties has been done in the bottling Shanghai, Shanghai Brewery large trials have proof of identification) applications in this area is not yet developed, if the formation of the market potential is great. 4, 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. Because it has the following specific advantages: ⑴ obvious coordination effect. Suitable for molybdenum, silicon, phosphorus, tungsten, nitrite formula, lack of coordination Effect, inhibition effect of greatly increased. ⑵ efficiency increases with increasing temperature. General corrosion inhibition efficiency increased with increasing temperature decrease, or even completely useless. But sodium gluconate on the contrary, inhibition rate within a certain range with increasing temperature increase, for example, carbon steel and other materials of the test, the temperature rose from 77 ℃ F on to 120 ℃ F, which buffer the average rate increased by 5% the above. So sodium gluconate this strange characteristic of high temperature systems or from low to high variable temperature system is ideal to use as a corrosion inhibitor. ⑶ scale capability: calcium, magnesium, iron has a strong complexing ability, so the scale are strong, especially for Fe3 + has excellent chelation, even in the full range of PH inside the role. ⑷ off pollution. Using sodium gluconate as circulating cooling water corrosion inhibitors, to reach off pollution, which is an advantage of other corrosion inhibitors currently in use can not be compared. 5, used in medicine: Regulate acid-base balance in the human body to restore normal nerve action, also for the same purpose for food additives. |
