Electrostatic application device and manufacturing method of thermoplastic resin sheet using same

摘要

The present invention relates to a method for producing a thermoplastic resin sheet having a uniform thickness using static electricity applying means capable of applying static electricity only in a predetermined direction. Both ends can be fixed and connected to a power source, using an electrostatic applying device comprising an elongated rod made of metal, covering 50 to 95% of the rod surface area along the length of the rod, and comprising a coating layer made of an insulating material. If it is, the thermoplastic resin sheet with a uniform thickness can be produced. In addition, it is easy to reduce the neck-in phenomenon of the sheet.
