Method of decomposing thermosetting resin, apparatus and heat control program

A control program for controlling heating of a thermosetting resin in a decomposition process of said thermosetting resin, wherein said program comprises the steps of:

• instructing a computer to heat a chamber accommodating the thermosetting resin up to a temperature T0;
• instructing the computer to determine if said temperature T0 of said chamber is in the range of 100 to 260° C., and if heating time is in the range of 0.5 min to 7 min;
• instructing the computer, when it is determined that said temperature T0 of said chamber is in the range of 100 to 260° C., and said heating time is in the range of 0.5 min to 7 min, to feed a decomposer to said chamber for a decomposition of the thermosetting resin;
• instructing the computer to heat said chamber at a temperature of less than the thermal decomposition temperature of the thermosetting resin;
• instructing the computer to detect the quantity of residual decomposer left in said chamber;
• instructing the computer to determine if the quantity of residual decomposer is less than 10%;
• instructing the computer, when it is determined that the quantity of residual decomposer is not less than 10%, to continue heating of said chamber while keeping the temperature of the thermosetting resin to less than the decomposition temperature of the thermosetting resin;
• and
• instructing the computer, when it is determined that the quantity of residual decomposer is less than 10%, to raise a maximum temperature from a temperature T1 at this moment up to T2, which is higher than T1.
