How Is Silica Gel Desiccant Regenerated And Reused?

May. 09, 2019

As a Humidity Indicator Card Supplier, let's share with you how to reuse the silicone desiccant. Silica gel desiccant will become cloudy after moisture absorption, indicating that it has absorbed moisture. How do we regenerate silica gel desiccant? You can open the silicone desiccant package, pour the desiccant into the container, put it in the microwave oven and heat it at 120 °C to 180 °C for 15 minutes. When the silica gel becomes transparent, dry the desiccant. The agent is placed in a dry, sealed container for cooling, and after cooling, the silica gel desiccant is packaged in a bag and reused. The same method of exposure and drying can be used, but the effect is not so good.

Silica Gel Desiccant

During the drying process of Silica Gel Desiccant, the temperature should be gradually increased to avoid the cracking of the silica gel caused by the intense drying. The excessive temperature of the Silica Gel Desiccant will cause the structural change of the silica gel to reduce the hygroscopic effect of the Silica Gel Desiccant. The fine particles are sieved to make the particles uniform, and they can be reused after being packaged.
