Painted Double Drum Hoist Winch to avoid direct contact between metal surfaces and air and moisture, extending the life of the equipment. On the other hand, Double Drum Hoist Winch painted in the poor environment of coal mines. It can make others discover in time and it is very eye-catching.
Double Drum Hoist Winch's first painting process is to treat the surface, because the surface may not be clean, there are all kinds of dirt, dust, coal dust, if these things are not wiped clean, direct paint will reduce the paint Adhesion is easily peeled off at a later stage, so that the metal surface is exposed again and accelerates corrosion.
