Regeneration of silica gel

- Apr 03, 2018 -

Silica gel adsorption moisture, can be removed by thermal desorption of water, heating the way there are a variety of, such as electric furnace, flue heat heating and hot air drying. The temperature control of the additional heat is suitable for 120--180℃, the blue glue indicator, the color-changing silica gel, and the Blue Silica gel are controlled in 100--120℃.

The maximum temperature of a variety of industrial silicone regeneration should not exceed the following limits:

The coarse-hole silica gel shall not be higher than 600 ℃;

The microporous silica gel shall not be higher than 200 ℃;

Blue Gum Index agent (or chromotropic silica gel) shall not be higher than 120 ℃;

Silicone aluminum adhesive shall not be higher than 350 ℃. After the regenerated silica gel, its moisture general control under 2% can again put into use.
