The current development and application of sodium gluconate are as follows:: Used in medicine: to regulate the acid-base balance in the human body to restore the normal function of nerves. It can be used as a food additive for the same purpose. : . Used as water quality stabilizer: Because sodium gluconate has excellent corrosion and scale inhibition effects, it is widely used as a water quality stabilizer. : , Used as a steel surface cleaning agent: If the steel surface requires pot plating, chromium plating, tin plating, or nickel plating to adapt to special purposes, such as manufacturing tinplate, galvanized sheets, surface chrome plating (electroplating), etc., the surface of the steel billet must be Clean strictly to make the coating firmly bond with the steel surface. At this time, adding sodium gluconate to the cleaning agent will achieve very ideal results. This has been confirmed by major international companies manufacturing tinplate. : , used as cement admixture: adding a certain amount of sodium gluconate to cement can increase the plasticity and strength of concrete, and has a blocking effect, that is, delaying the initial and final solidification periods of concrete. Therefore, sodium gluconate is used as a cement admixture. Agents have been widely used in important construction projects abroad, such as a large number of bridge construction projects in the Middle East. : In addition, it can also be used in electroplating and film manufacturing industries. : Product quality indicators
Song Dynasty>& Product introduction of sodium gluconate in the field of concrete
Song Dynasty sodium gluconate can be used as an admixture in concrete. Its functions in concrete are as follows: water reducing agent and retarder agent.
: Sodium Songti Gluconate is generally used alone, but it can also be used in combination with other retardants such as carbohydrates and phosphates. Sodium gluconate is a crystalline powder. It is produced under properly defined and controlled conditions. This compound is chemically pure and non-corrosive. Quality is constant. These features ensure reliable and repeatable results in applications.
: Sodium gluconate is used as a water-reducing agent
: By adding a water-reducing agent, the water to cement ratio (/) can be reduced. The following effects can be obtained by adding sodium gluconate:
: Song Dynasty Song Dynasty improves workability. When the water to cement ratio (/) remains unchanged, adding sodium gluconate can improve workability. At this time, sodium gluconate acts as a plasticizer. When the added amount of sodium gluconate is below .%, the degree of improvement in workability is directly proportional to the added amount.
: Songti Songti increases strength when the cement content remains constant while the water content in the concrete can be reduced (i.e./decreased). When the added amount of sodium gluconate is .%, the amount of water added can be reduced by %.
: Song Dynasty Song Dynasty reduces the cement content. The water and cement content are reduced in the same proportion, and the / ratio remains unchanged. At this time, sodium gluconate is used as cement reducing agent. In general, the following two aspects are important to the performance of concrete: shrinkage and heat generation.
: Sodium Songti Gluconate as a retarder
: Sodium Songti Gluconate can significantly delay the initial and final setting time of concrete. When the dosage is below .%, the logarithm of the initial solidification time is directly proportional to the dosage. That is, doubling the dosage will delay the initial solidification time to ten times, which makes the working time from a very short time. Fewer hours extend into days without sacrificing intensity. This is an important advantage especially on hot days and when it needs to be left in place for an extended period of time.
: Using sodium gluconate in Song Dynasty, the / ratio can be reduced, which can increase the strength of concrete. This is a high-quality concrete.
: It is difficult to construct large and heavy pouring projects. Due to the addition of sodium gluconate, the workability of concrete is improved and the setting time is delayed, which can avoid the occurrence of contact surfaces on the structure, and as a result, the structural strength can be enhanced.
: It is of great significance to improve workability by keeping the / ratio unchanged in hot areas. Large amounts of sodium gluconate were used in the construction of bridges in the Middle East.
: Songti Songti adds sodium gluconate to the concrete mixture to delay the setting time, which is very important for long-term and difficult pouring.
: In the modern concrete industry, ready-mixed concrete is prepared at a central location and then transported by mixer trucks. In this case, it is important to increase workability and initial setting time.
: The lower / ratio of Song Dynasty Song Dynasty can make concrete with higher strength and durability. Sodium gluconate can achieve this purpose. This is very important for high-strength reinforced concrete.
: Song Dynasty Song Dynasty prefabricated masonry mortar must be usable for a long time. Adding sodium gluconate can extend the working period.
: Songti Songti oil well grouting grout is difficult to operate due to high temperature. After adding sodium gluconate, the concrete can work at ℃ temperature for several hours.
