PROBLEM TO BE SOLVED: To remove and decontaminate an asphalt filler strongly fastened to the inside of a vessel of a stabilizer and a surface of an inside electronic part by a simple method.SOLUTION: An asphalt filler is removed from a vessel and an inside electronic part by processing by a processing process of including: a disassembling process of separating into the vessel, the asphalt filler and the inside electronic part by taking out the inside electronic part after roughly removing the asphalt filler 5 from the vessel 4 of the stabilizer; a folding process of forming the vessel into a plate shape by folding a wall surface of the vessel firmly fixed with the asphalt filler; an immersion process of swelling the asphalt filler by transferring PCB into a hydrocarbon solvent while immersing and agitating the vessel formed in the plate shape and the inside electronic part in the hydrocarbon solvent; and a separation process of separating the swollen asphalt filler from the vessel and the inside electronic part by taking out the vessel formed in the plate shape and the inside electronic part from of the hydrocarbon solvent. |
