Silica gel desiccant is a kind of transparent particles, no toxic smell, it can be reused. Silica gel desiccant will crackle when thrown into water, relying on its own porous structure to absorb moisture in the environment, and can be used continuously after drying. Let the editor of Shenzhen Mingwei Industry explain to you what are the drying methods of silica gel desiccant?

The drying method of silica gel desiccant is as follows:

1. The desiccant can be exposed to the sun, and the silica gel desiccant after exposure can remove some water.

2. The moisture can be removed by thermal desorption. There are many heating methods, such as electric furnace, flue waste heat heating and hot air drying. The temperature for removing the additional heat should be controlled at 120-180℃, and for blue gel indicator, discoloration silica gel, and DL-type blue silica gel, the temperature should be controlled at 100-120℃.

When calcining silica gel desiccant silica gel, too high temperature will cause changes in the pore structure of silica gel, which will significantly reduce its adsorption effect and affect its use value. For blue gel indicator or color-changing silica gel, the desorption temperature should not exceed 120°C, otherwise the color development effect will be lost due to the gradual oxidation of the color developer.

The above is about the drying method of silica gel desiccant, I hope it will be helpful to you.
