Factors affecting the color of Sodium gluconate
Normal Sodium Gluconate is in the form of white crystalline particles or powder. If some impurities are mixed into the sodium gluconate, it will affect its color, even if the content of these substances is very small, it will be clearly reflected. These impurities mainly include iron, copper, diamond, chromium, manganese, cerium, vanadium, lead and so on. The influence of impurities on it is not only limited to the change of color, but also the influence of the metal ions contained in these impurities on the performance of the product.
The rutile type in sodium gluconate reacts very obviously to the content of these impurities. When the iron oxide content in the rutile type sodium gluconate is greater than 0.003%, it will show a very bright color, while the content in anatase type sodium gluconate The color reaction will occur only if it is greater than 0.009%. Therefore, the degree of reaction of different types of sodium gluconate to impurities is different. We must strictly control the content of these impurities during the production process, which is not only a guarantee for product quality, but also an effective measure to enhance product competitiveness.
The performance of Sodium gluconate
Sodium Gluconate is a product obtained from sodium gluconate solution obtained by catalytic oxidation with glucose and sodium hydroxide as raw materials, and then concentrated, cooled and crystallized. According to the technological process, it is divided into solid sodium gluconate and liquid sodium gluconate. The solid sodium gluconate is divided into industrial grade and food grade according to purity and impurities.
Sodium gluconate has been widely used in various products in our lives, so in terms of safety, it can be regarded as the safest product among chemicals, but the quality is caused by some negligence in the production work. The drop is likely to cause serious quality problems in the application, so it is necessary to deal with some conditions when using the material to achieve the stability of the effect in the application. The quality and performance of sodium gluconate can be adjusted by adjusting some methods in production and the use of additives, so that the overall performance of the product can be improved during the production process, and it can also be used in use. Give full play to its own performance and role, and maintain the safety in use.
Therefore, in order to avoid unstable performance caused by failure to handle process errors and losses in production, it is necessary to understand the main production process of sodium gluconate, and at the same time, some unstable conditions in production Increase and adjust to reduce the possibility of damage to product performance caused by such unstable factors, so that the usability will be improved.
China,Bailin Group Co.,Ltd is a leading group company which produce and supply high quality Sodium gluconate for both industrial and food grade.
The characteristics of sodium gluconate as a water treatment agent:
When sodium gluconate is used as a water treatment agent, it is also a limited dissolution agent. It also has the following characteristics:
Sodium gluconate can be combined with many corrosion inhibitors to present a synergistic effect. It is used in molybdenum formulations to enhance the corrosion inhibition effect of the main corrosion inhibitor molybdate. It is also suitable for formulas such as silicon series, phosphorus series, boron series, tungsten series, nitrite series and some organic corrosion inhibitor series.
2. The corrosion inhibition rate increases with increasing temperature
For most corrosion inhibitors, as the temperature increases, the corrosion inhibition rate decreases. However, the relationship between the corrosion inhibition rate of sodium gluconate and the temperature is opposite. Not only does the corrosion inhibition rate do not decrease with the increase in temperature, but within a certain temperature range, the corrosion inhibition rate increases with the increase in temperature. For example, it is reported that the corrosion resistance of carbon steel material rose from 77°F to 124°F, but the corrosion inhibition rate increased by 5%.
3. Excellent complexing performance
Gluconic acid has an excellent corrosion inhibition effect, which is related to its excellent complexing performance, and it also has a good scale inhibition effect. The chelating performance of gluconic acid to Fe ions is more prominent.
4. No pollution, low price
Using sodium gluconate as a corrosion and scale inhibitor for circulating cooling water will not cause environmental pollution, which is an incomparable advantage to some corrosion inhibitors currently used. It is the cheapest one among the organic synthetic agents currently in use. Therefore, its use is increasingly widespread.
How does sodium gluconate remove scale？
Water is the source of everything. People can skip meals for 3 days, but they have to drink water. On average, everyone drinks 8 glasses of water a day. But in our daily life, there is scale in water, how should we solve it? Sodium gluconate is used as a water stabilizer, and its superiority is shown in:
1. It has an obvious coordination effect and is suitable for various formulations such as molybdenum, silicon, phosphorus, tungsten, nitrite, etc. Due to the coordination effect, the corrosion inhibition effect is greatly improved;
2. Contrary to general corrosion inhibitors, the corrosion inhibition rate increases with increasing temperature;
3. The technical requirements for scale inhibition ability have strong complexing ability for calcium, magnesium, and iron salts, especially for Fe3+;
4. As a corrosion and scale inhibitor for circulating cooling water, it is unmatched by other corrosion and scale inhibitors currently used, and can achieve the effect of eliminating public hazards.
