The problem of silicone regeneration should be noted.

- Mar 06, 2018-

  1. drying regeneration should pay attention to gradually raise the temperature to avoid violent drying caused by rubber particles burst, reduce recovery.

  2. on the roasting and regeneration of silica gel, the temperature is too high will cause changes in the pore structure of silica gel and significantly reduce the adsorption effect, affecting the use value. For the blue plastic indicator or color silica gel, desorption regeneration temperature should not exceed 120 ℃, otherwise it will be due to the gradual oxidation of the developer to lose color.

  3. Regenerated silica gel should generally sieve to remove fine particles, so that the particles are uniform.
