Dongfeng Commercial Vehicle D530 Metal Paint Capacity Upgrading Project Launched

Recently, the author learned from Dongfeng Commercial Vehicle Body Factory that the D530 metallic paint capacity enhancement project of Dongfeng Commercial Vehicle Co., Ltd., one of the key investment projects in 2009, has been started. It is expected to be completed in September 2010 and the project will be able to meet the requirements of the D310. The mixed-flow production of 11 models, including the D530 models, has reached an annual capacity of 100,000 vehicles, and the body coating quality indicators have reached the domestic advanced level. It is reported that the D530 metal paint capacity improvement project has exceeded 100 million yuan in only one phase of investment. One of the biggest highlights of the project is to apply resource-conserving and environmentally friendly materials and processes as the starting point and adopt a large number of advanced and mature technologies in the project. , Reliable technical equipment and clean processes to minimize pollution emissions. In the paint spraying method of the D530 metallic paint capacity improvement project, the current domestic leading robotic automatic electrostatic spray process is adopted. Compared with the old air spray method, it not only can greatly reduce the labor intensity of the workers, but also can The paint utilization rate is increased by 20%-30%, which greatly reduces the paint consumption. In terms of emissions, the exhaust gas produced in the finish paint drying room and the drying oven must first be treated by the purifying device until it meets the requirements of the national environmental protection regulations.

At the same time, an energy-efficient π-type drying furnace was adopted in the top coat drying oven, which saved energy consumption by about 20% compared with the conventional straight-through drying oven.
