Problems needing attention in the regeneration of silica gel

Lohas Silicone Rubber Co.,Ltd | Updated: Jun 01, 2017

Shan drying and regeneration should be aware of the gradual increase in temperature, so as to avoid severe drying caused by rubber particles burst, reducing recovery.

When the Shan of silica gel is regenerated, the temperature of silica gel will cause the change of pore structure and decrease the adsorption effect and the use value. For the blue glue indicator or chromotropic silica gel, the temperature of the desorption should not exceed 120 Shan, otherwise it will lose its color effect because of the gradual oxidation of chromogenic agent.

Shan after the regeneration of silica gel should be screened to remove fine particles, so that the particles even.

Storage and Packaging

Silica gel has a strong moisture absorption capacity, so should be stored in the dry place, between the packaging and the ground to have shelves. Packaging has steel barrels, paper barrels, cartons, plastic bottles, polyethylene plastics composite bags, flexible bags and so on. The transport process should avoid rain, damp and exposure.
