Used as a steel surface cleaner:
If the steel surface needs to be chrome-plated, chrome-plated, tin-plated or nickel-plated to suit specific applications, such as making tinplate, galvanized sheet, chrome (electric), etc., the slab surface must be strictly cleaned to make the coating and steel. The surface is firmly bonded, and the addition of sodium gluconate to the detergent at this time will achieve a very desirable effect. This has been confirmed by the large companies that manufacture tinplate internationally.
Performance and usage
Chemical name :Sodium Gluconate
Used as a cement admixture:
Adding a certain amount of sodium gluconate to the cement can increase the plasticity and strength of the concrete and has a retarding effect. That is, delaying the initial and final settling time of the concrete, for example, adding 0.15% sodium gluconate can extend the initial solidification time of the concrete by more than 10 times. For example, in high temperature season construction and large engineering operations, the delayed initial solidification time is One problem, and sodium gluconate can satisfactorily solve this problem. In addition, it is difficult to bond oil wells at high temperatures. The concrete after the addition of sodium gluconate can be plasticized in a few hours at a high temperature of 170 ° C, so that the above problems can be satisfactorily solved. Sodium gluconate has been widely used as a cement admixture in important foreign construction projects, such as a large number of bridge projects in the Middle East. It is reported that sodium cellulose sulfonate is extracted from papermaking wastewater, and its effect is incomparable with sodium gluconate.

Application of sodium gluconate in construction industry
The sodium gluconate industrial grade can be reduced by adding a water reducing agent to a water to cement ratio (W/C). By adding sodium gluconate, the following effects can be obtained: 1. Improve workability When the water to cement ratio (W/C) is constant, the addition of sodium gluconate can improve workability. At this time, sodium gluconate functions as a plasticizer. When the amount of sodium gluconate is less than 0.1%, the degree of improvement in workability is proportional to the amount added. 2. Increase the strength When the cement content remains unchanged, the water content in the concrete can be reduced (ie, the W/C is reduced). When the amount of sodium gluconate added is 0.1%, the amount of water added can be reduced by 10%. 3. Reducing the cement content The water and cement content are reduced in the same proportion, and the W/C ratio remains unchanged. At this time, sodium gluconate is used as a cement reducing agent. In general, the following two aspects are important for the performance of concrete: shrinkage and heat generation.
