Rotary atomizing head of a rotary atomizing electrostatic coating apparatus

摘要

A bell head of a rotary atomizing electrostatic coating apparatus includes a bell head body made from high electric resistance material, a semi-conductive layer formed on an outside surface of the bell head body, and a high electric resistance layer formed on an outside surface of the semi-conductive layer. The high electric resistance layer is also of a chemical-proof and of a thinner-proof type.
