Can Silica Gel Desiccant Be Reused?

Dec. 28, 2018

Silica Gel Desiccant is a Environmentally Friendly Desiccant,and highly active adsorbent material, the main component is silica, which is a highly active adsorbent material. It is usually prepared by reacting sodium silicate with sulfuric acid and undergoing a series of post-treatment processes such as aging and acid foaming. Silica gel is an amorphous material, and its shape is transparent and irregular, and its chemical formula is mSiO2.nH2O.

The most suitable moisture absorption environment for Silica Gel Desiccant Packets is room temperature (20~32 °C) and high temperature (60~90 °C), which can reduce the relative humidity of the environment to about 40%, so the desiccant application range is very wide.

1. Explode in the sun (but the water can't be completely exposed).

2. Silica Gel Desiccant can be reused after baking at high temperature. It can be baked at 80-120 degrees Celsius, and the adsorbed water can be baked for repeated use. However, it should be noted that the inner layer of the desiccant bag is heat-sealed and has a temperature resistance of 80-120 degrees, so the bag needs to be torn off and then baked (most of the wrapping paper cannot withstand high temperatures, so it should be under low temperature and long time. Drying, and the cost of packaging materials that can be directly baked is high and does not meet economic benefits.)
