Food Grade Sodium Gluconate Is Widely Used In Industry

 Food Grade Sodium Gluconate Food grade sodium gluconate is widely used in industry, food grade sodium gluconate can be in the construction, textile printing and dyeing and metal surface treatment and water treatment industries such as efficient chelating agent, steel surface cleaning agent, glass bottle cleaning agent, electroplating industrial aluminum Oxygen coloring, in the concrete industry for efficient retarder, superplasticizer and so on.

  Used as a steel surface cleaning agent:

  Steel surface such as the need for plating, chrome, tin, nickel to adapt to special purposes, such as the manufacture of tinplate, galvanized sheet, the surface chrome (electricity), the billet surface are subject to strict cleaning, so that the coating and steel The surface of a solid combination, this time its cleaning agent to add food grade sodium gluconate will achieve very good results. This has been confirmed by international companies making tinplate.

  Used as a cement admixture:

  Food Grade Sodium Gluconate Cement to add a certain amount of food grade sodium gluconate, can increase the plasticity and strength of concrete, and a blocking effect

  , That is, delayed the initial and final solidification period of concrete, such as the addition of 0.15% of the food grade sodium gluconate, the concrete can be the initial setting time of more than 10 times longer, that is, the plastic molding time from a few hours to a few days, Does not affect its fastness. Plasticity and retardation The initial setting time is very important in concrete operations. For example, in the high temperature season construction and large engineering operations, it is a difficult problem to delay the initial setting time. The food grade sodium gluconate can solve this problem satisfactorily. In addition to high temperature bonding oil wells is more difficult to add food grade sodium gluconate concrete at 170 ℃ high temperature, within a few hours of plastic, it can also satisfactorily solve the problem. Therefore, sodium gluconate as a cement admixture in foreign countries has been widely used in important construction projects, such as a large number of bridges in the Middle East. But our domestic application in this area has not yet been applied, it is said that in the papermaking wastewater extraction of sodium cellulose sulfonate, the effect and food grade sodium gluconate is simply comparable.

  In addition can also be used in electroplating, film manufacturing industry.

  As a kind of polyhydroxycarboxylic acid type of good corrosion and scale inhibitor food grade sodium gluconate, due to the above-mentioned many specific properties, such as in the application of technology willing to work hard, will be developed into a large industry.

  Application of Food Grade Sodium Gluconate in Construction Industry

  The concrete is a composite material made of cement, aggregate, blending agent and water. Concrete is the largest amount of all artificially manufactured material. Three quarters of the concrete is aggregates, but the most active ingredient in the concrete is the cement slurry. The properties and properties of concrete are mainly determined by the nature of the cement slurry. Admixtures in concrete can provide beneficial effects such as accelerated solidification, retardation of solidification, the presence of air bubbles, reduced water consumption and increased plasticity, and so on. Typically, several admixtures are used in the cement, and various admixtures can be reinforced in some applications.

  Food grade sodium gluconate can be used as a blending agent in concrete, its function in concrete as follows: water reducing agent and retarder

  Food grade sodium gluconate is generally used alone, but it can also be used with other retarders such as carbohydrates and phosphates. Food grade sodium gluconate is a crystalline powder. Is produced under the conditions of proper regulation and control. This compound is chemically pure and non-corrosive. The quality is constant. These features ensure that it has reliable and reproducible results in the application.

  Food grade sodium gluconate as a water reducing agent

  Food Grade Sodium Gluconate By adding a water reducing agent, the water to cement ratio (W / C) can be reduced. By adding food grade sodium gluconate, we can achieve the following effects: 1, to improve the workability in the water to cement ratio (W / C) the same circumstances, adding food grade sodium gluconate can improve workability. At this time, food grade sodium gluconate is the role of plasticizer. When the amount of sodium gluconate in the food is less than 0.1%, the degree of improvement is proportional to the amount added. 2, enhance the strength When the cement content remains constant and the water content of concrete can be reduced (ie, W / C reduced). When the amount of food grade sodium gluconate is 0.1%, the amount of water added can be reduced by 10%. 3, reduce the water content of cement and cement to reduce the proportion of the same, W / C ratio remains unchanged. At this point, food grade sodium gluconate as a cement reducing agent. Under normal circumstances, the following two aspects of the performance of concrete is very important: shrink and produce heat.

  Food grade sodium gluconate as retarder

  Food grade sodium gluconate can significantly retard the initial and final solidification time of concrete. When the dosage is 0.15% or less, the logarithm of the initial solidification time is proportional to the amount of the addition, that is, the addition time is doubled and the time of the initial solidification is delayed by ten times, A few hours extended to a few days without compromising the strength. Especially in the hot days and need to place a long time, this is an important advantage.

  Used as a special cleaning agent for glass bottles:

  Beverage industry, food industry, the date of the brewing industry to hundreds of millions of glass bottles, such as vials, beer bottles, milk bottles, canned bottles, soy sauce bottles, bottles, etc., the cleaning work is a very important thing to clean Agent of the pharmaceutical formula is a difficult technical work. At present, China has not yet appeared in a more ideal agent. The main problems are: the cleaning force is not strong, easy to plug the bottle washing machine nozzle and pipe; bottle stickers and bottlenecks rust is not ideal; washed after the residue of food safety is not ideal (such as phosphate Residue); washing water discharged into public pollution (can not meet the national standards). Such as in its glass bottle detergent formulations to use sodium gluconate as the main body, the above problems can be solved. (The eighties in Shanghai soda plant, Shanghai brewery to do a large test, there are identification) in this application has not yet developed, if the formation of the market, great potential.

  Used as a water stabilizer:

  Food Grade Sodium Gluconate As the food grade sodium gluconate has excellent corrosion and scale inhibition, it is widely used in water quality stabilizers, such as as a petrochemical enterprise circulating cooling water system, low pressure boiler, internal combustion engine cooling water system and other treatment agents. Because it has the following specific advantages: ⑴ has a significant coordination effect. Applicable to molybdenum, silicon, phosphorus, tungsten, nitrite and other formulations, due to the coordination effect, corrosion effect greatly improved. ⑵ corrosion rate increases with increasing temperature. General corrosion inhibitor with the temperature rise and decline in corrosion rate, or even completely lost its role. But the food grade sodium gluconate on the contrary, the corrosion rate in a certain range with the temperature rise, for example, carbon steel and other materials in the test, the temperature from 77 ℃ F to 120 ℃ F, the buffer rate increased More than 5%. Therefore, the food grade sodium gluconate this strange characteristics, the higher temperature system or from low temperature to high temperature of the temperature system for corrosion inhibitor is very ideal. ⑶ scale inhibition capacity: calcium, magnesium, iron salts have a strong ability to complex, so the scale inhibition capacity is very strong, especially for Fe3 + has excellent chelating effect, even within the full PH range of the role. ⑷ off pollution. The use of food grade sodium gluconate as a circulating cooling water corrosion inhibitor, to achieve pollution, which is currently used by other corrosion inhibitors can not match the advantages.
