Analysis of the causes of sodium fluorosilicate agglomeration

Sodium fluorosilicate often finds certain agglomeration of sodium fluorosilicate when it is used. What causes the sodium fluorosilicate agglomeration?

    1. The chemical composition of sodium fluorosilicate. The raw materials for the production of sodium fluorosilicate generally contain fluorosilicic acid, industrial salt and industrial water. Industrial and industrial waters generally contain some calcium ions, ferrous ions, and some insoluble suspended solids. These impurities are present in sodium fluorosilicate and precipitate under certain conditions, causing the particles to gradually bridge and gradually form agglomerates.

    2. The size and shape of the sodium fluorosilicate particles. The smaller the sodium fluorosilicate particles, the larger the surface area of the sodium fluorosilicate, so the contact surface with air will be larger, and the more water will be absorbed from the air, the more likely it will cause agglomeration. If the particles are not uniform, small particles will be added between the large particles, and the contact area becomes larger, which is more likely to cause agglomeration of sodium fluorosilicate.

    3. The content of water in sodium fluorosilicate. On the one hand, the water in the sodium fluorosilicate causes a crystal bridge between the particles, resulting in agglomeration of sodium fluorosilicate. On the other hand, the moist sodium fluorosilicate becomes soft, easily deformed under pressure, and the contact area of the particles is increased, and the bonding strength between the particles is also increased. Therefore, if the sodium fluorosilicate contains too much water, it will cause the sodium fluorosilicate to agglomerate more easily.

    4. The effect of temperature on the agglomeration of sodium fluorosilicate. If the ambient temperature fluctuates, the water will cause impurities in the sodium fluorosilicate particles, causing the sodium fluorosilicate crystal to repeat, causing agglomeration.

    5. The pressure when storing sodium fluorosilicate. In order to save the storage space of sodium fluorosilicate, generally sodium fluorosilicate will be stacked together for storage, which leads to an increase in the contact area between the sodium fluorosilicate particles, so the possibility of agglomeration is also greatly increased. increase.
