Coating pre-treatment equipment

Pre-treatment equipment, mainly the use of physical mechanical erosion and chemical reaction principle deal with the workpiece; hanging in the logistics of the workpiece conveyor line in order to enter the pre-treatment equipment shed body treatment liquid corresponding step in the suction pump, sprinkler piping distribution and lower nozzle atomization, by a certain pressure, flow and temperature uniformity is sprayed on the surface, the surface of the grease, oxide, dust and debris to be cleaned; then the substrate and the bath is a chemical reaction, the workpiece final coating with excellent anti-corrosion base layer. Pre-treatment equipment and production according to the different shape of the workpiece, the main form of structure impregnated, tunnel by spraying; impregnated applicable to large, stupid pieces yield modest production line; tunnel by spraying for small workpieces and yield greater production lines; pre-treatment equipment, mainly by the process tank, bath stirring system, bath heating system, phosphate slag removal systems, ventilation systems, to the part of the drain pipe line and logistics transportation system and other components.
