自动静电喷涂电压与喷涂效果
Automatic electrostatic spraying voltage and spraying effect
在静电磁场下，对漆粒有一个作用力，电场力的大小取决于电场强度与漆粒上的电荷量。作用力的方向同电力线的方向相同，会在一定程度上加快漆粒的运动速度。电压升高会使产生的离流子增加，加强静电场的电场力，被涂物体表面部位的磁力线密度较高，在折角、边缘部位的锐角处，使涂料的上漆率增加，导致流挂、气泡等缺陷。
Under the static magnetic field, there is a force on the paint particles. The magnitude of the electric field force depends on the electric field strength and the amount of charge on the paint particles. The direction of the force is the same as that of the power line, which will speed up the movement of paint particles to a certain extent. The increase of voltage will increase the generated current separator, strengthen the electric field force of electrostatic field, and the magnetic line density of the surface of the coated object is higher. At the sharp corner of the corner and edge, the coating rate will increase, resulting in defects such as sagging and bubbles.
