PROBLEM TO BE SOLVED: To reduce generation of harm substances by emulsifying polyvinyl chloride liquid, aluminum oxide, and silicon dioxide within a supersonic emulsification device, and by treating emulsified substances in an electric resistance furnace at a specific temperature to vitrify them. SOLUTION: Mixture members of polyvinyl chloride liquid, aluminum oxide, and silicon dioxide are inserted into a supersonic emulsification device 2 and are emulsified at a temperature of 1500 to 2000 deg.C. This emulsified mixture member is conveyed through an electromagnetic valve V2, a pump P2, a pipe 21, a monitoring section 8, an electric resistance measuring section 9, and an electromagnetic valve V5 to an electric resistance furnace 5, is melted vitrified at a melting temperature of 1500 to 2000 deg.C, is discharged from a discharging section 11, and is cooled and hardened to form a glass member. Emulsified and mixed conditions are monitored through a glass window provided at the monitoring section 8, and the electromagnetic valves V1, V4, V5, the pumps P1, P2, and the like are controlled according to a measured electric resistance valve of the electric resistance measuring section 9. In this way, generation of harm substances can be reduced and treated. |
