분체 도장 라인 전처리 시스템

The pre-treatment system of the 분체도장 라인 is a key link to ensure the quality of spraying. Its main function is to remove impurities such as oil, rust, dust, 등. on the surface of the workpiece, so that the surface of the workpiece is clean and suitable for spraying. The system usually includes multiple treatment tanks such as pre-degreasing tank, degreasing tank, water washing tank, pickling tank (selectively used according to the material and surface condition of the workpiece), neutralization tank, phosphating tank, pure water washing tank, 등. The workpiece passes through each tank in turn through the hanging conveyor chain. Under the action of different chemical agents, the surface is cleaned and converted to form a surface state that is conducive to powder adsorption and coating adhesion.
