At DIXCEL, a strict temperature control is implicated at each step of the heat treatment process.
The details of the time and temperatures of the heat treatment process cannot be disclosed, so hypothetical values will be used to explain the heat treatment process.
First, the temperature is increased by 5 degrees centigrade every 10 minutes. When the temperature reaches 300 degrees centigrade, the temperature is kept the same for 8 hours.
Next, the discs are cooled by temperature being lowered by 5 degrees centigrade every 10 minutes. The graph on the left shows that the temperature control is very ideal.
The whole heat treatment process is completed over a period of 24 hours. This allows for slow and gradual process under perfect humidity control.
This helps prevent deformation, strengthens the bonds between the molecules, and allows for an increase in heat resistance.
※The temperatures and times listed in this explanation are hypothetical values. The actual temperatures and times that DIXCEL uses are different.
