After that, the container with chips is removed from the bath and dried in a furnace at a temperature of 100-105°C for 50-60 minutes, and then the chips are removed from the furnace and kept in the open air for 20-30 minutes. Finally, the first part of the chips is mixed with the second part of the chips in a ratio of 1:1.
