Abstract:
1. A stain preventing cover for covering a surface of an electrostatic coating machine produced from a composite sheet as a raw material which is formed by laminating a first sheet material having a low dielectric constant and having insulation performance, a second sheet material having a dielectric constant higher than that of the first sheet material or having semiconductivity and a third sheet material having a dielectric constant lower than that of the second sheet material and having insulation performance, wherein the first sheet material is formed so as to be positioned inside of the cover; and an end of the second sheet material is positioned close to or connected to an electrostatic high voltage part of the coating machine and another end thereof is positioned distant from an earth part of the coating machine; the second sheet material is made of polyurethane, and the stain preventing cover is fitted to a power department of the electrostatic coating machine.
