Method of decomposing thermosetting resin, apparatus and heat control program

摘要

Disclosed is a method of decomposing a thermosetting resin by a decomposer. This method comprising the steps of pre-heating the thermosetting resin up to a pre-heating temperature T0, kneading the pre-heated thermosetting resin together with a decomposer, and concurrently heating a mixture comprising the thermosetting resin and the decomposer up to a kneading temperature T1, thereby allowing a reaction to take place between the decomposer and the thermosetting resin to obtain a kneaded matter wherein the decomposer has been consumed, and heating the kneaded matter to a maximum temperature T2 to thereby decompose the thermosetting resin, wherein the pre-heating temperature T0 is not higher than the boiling temperature of the decomposer, the kneading temperature T1 is not lower than the pre-heating temperature T0 but is lower than the thermal decomposition temperature of the thermosetting resin, the maximum temperature T2 is lower than the decomposition temperature of the thermosetting resin, and the pre-heating of the thermosetting resin is performed under the following conditions of temperature T0 and time t: 100 DEG C 0.5 min
