Gluconic Acid 50% Solution can not replace the five reasons
Why do Gluconic Acid 50% Solution is irreplaceable? What makes it take such an important position?
Mainly by the five aspects to decide, it is these five functions and uses only make Gluconic Acid 50% Solution has been favorable.
First, for the 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 with the steel surface firmly bonded, this time its cleaning agent added Gluconic Acid 50% Solution will achieve a very satisfactory results.
Second, as a cement admixture:
Cement to add a certain amount of Gluconic Acid 50% Solution, can increase the plasticity and strength of concrete, and have a blocking effect.
Three, that is, to delay the initial and final solidification period of concrete, such as adding 0.15% Gluconic Acid 50% Solution, the concrete can be the initial solidification time more than 10 times, that is, the plastic plastic time from a few hours extended to a few days, Without affecting its fastness.
Plasticity and retardation The initial setting time is a very important problem 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 50% solution of gluconic acid can solve this problem satisfactorily.
In addition, high temperature bonding oil wells is more difficult to add Gluconic Acid 50% Solution solution after the concrete at 170 ℃ high temperature, within a few hours of plastic, it can also satisfactorily solve the problem.
Therefore, Gluconic Acid 50% Solution solution as a cement admixture in foreign countries has been used in a large number of 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 of Gluconic Acid 50% Solution solution is simply not comparable.
In addition can also be used in electroplating, film manufacturing industry.
As a polyhydroxycarboxylic acid type of good corrosion and scale inhibitor Gluconic Acid 50% Solution, 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.
Four, Gluconic Acid 50% Solution in the construction industry in the application:
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 aggregate, 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. Sodium gluconate can be used as a blending agent in concrete, and its function in concrete is as follows:
Water reducing agent and retarder, Gluconic Acid 50% Solution is generally used alone, but can also be used with other retarders such as carbohydrates and phosphates.
Gluconic Acid 50% Solution 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.
5, Gluconic Acid 50% Solution as a water reducing agent:
By adding a water reducing agent, the water to cement ratio (W / C) can be reduced.
By adding a Gluconic Acid 50% Solution, the following effects can be obtained:
1, to enhance the work of water to cement ratio (W / C) the same circumstances, adding Gluconic Acid 50% Solution can improve workability.
At this time, Gluconic Acid 50% Solution solution is the role of plasticizer. When the amount of Gluconic Acid 50% Solution is less than 0.1%, the degree of improvement of workability 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 addition of Gluconic Acid 50% Solution is 0.1%, the amount of water added can be reduced by 10%.
