粉末静电喷涂中 ,成品粉末需要经过高速旋转的螺杆 ,使粉末在离心力的作用下 ,通过静止不动的旋转筛网筛选后进入供粉桶 ,然后通过高压静电喷枪使粉末带电后喷涂到工件上。旋转筛网不仅仅起到过滤粉末的作用 ,它还通过旋转筛网内的导电纤维将粉末中多余电荷释放掉 ,避免因粉末 Powder electrostatic spraying, the finished powder needs to go through high-speed rotation of the screw, so that the role of centrifugal force in the powder, through the stationary rotary sieve sieve into the powder barrel, and then through the high-voltage electrostatic spray gun after spraying powder to the workpiece . The rotating sieve not only functions as a filter powder, it also discharges excess charge in the powder by rotating the conductive fibers in the sieve,
