Factors Affecting The Stability Of Sodium Aluminate Solution

1. The caustic ratio of the solution Increasing the caustic ratio of the industrial sodium aluminate solution at any temperature can improve the stability of the solution. Practice has proved that the sodium aluminate solution with a caustic ratio of 1.0 decomposes instantly, the solution with a caustic ratio of 1.4~~1.8 is relatively stable under production conditions, and the solution with a caustic ratio of 3 or more will not decompose for a long time

2. The temperature of the solution When Αk and the concentration are constant, the stability decreases with the decrease of the temperature until the temperature = 30 degrees.

3. The concentration of alumina has a certain special relationship. Under a certain caustic ratio and a certain temperature, solutions with concentrations below 25 and above 250 have high stability, and solutions with concentrations close to dilute or concentrated solutions are stable. less sexual. And moderate concentrations are less stable.

4. Impurities generally exist in the solution in the form of sodium salts, such as: sodium soil acid, sodium humate, sodium oxalate, etc. Some of them can be increased and some can be reduced.

5. The crystallization core, also called crystal seed, will be described in detail in the following desiliconization and decomposition process.

6. Mechanical stirring can promote the diffusion of the solution, which is conducive to the vigilant growth.
