Silica gel adsorbed Moisture, can be removed by thermal desorption, heating methods have a variety of, such as electric furnace, flue gas heat and hot air drying and so on. The temperature control of the 120-180 Shan is advisable for the blue glue indicator, the color-changing silica gel, and the Blue Silica gel to be controlled in 100-120 Shan. The maximum temperature of a variety of industrial silicone regeneration should not exceed the following limits:
Coarse-hole silica gel shall not be higher than 600 Shan;
Fine pore silica gel shall not be higher than 200 Shan;
Blue Glue index Agent (or discoloration silica gel) shall not be higher than 120 Shan;
Silicone glue shall not be higher than 350 Shan.
After the regenerated silica gel, its water general control under 2% can be put into use again.
