Silica gel in the production process will produce adverse product, or group to stay the salvage, silica gel products factory in these cannot be reproduced, only to sell some silica gel regeneration plant, the following is some of the technical content of plant regeneration.
The drying regeneration should pay attention to the master gradually increase the temperature, to avoid burst particles caused severe drying, reduce the recovery rate.
Exept of silica gel roasting regeneration, the temperature is too high will cause changes in pore structure of silica gel and significantly reduce the adsorption effects, the impact of use value. The temperature of desorption and regeneration should be no more than 120 degrees Celsius for blue gel indicator or color changing silica.
3 after regeneration, silica should generally be sifted to remove fine particles, so that uniform particles.
Storage and packaging:
Because the silica gel has a strong moisture absorption capacity, so it should be stored in a dry place, there should be a shelf between the pack and the ground. There are steel drums, drum, packaging cartons, plastic bottles, plastic compound bag, flexible container bags etc.. To avoid rain, moisture and exposure should be in the process of transportation.
