ABSTRACT The coating process of tractor cabs is performed in industry by the electrostatic powder coating technique, which is the electrostatic application of powder to metal parts of the cab, requiring a protective coating. This process ensures the application of powder coating on e-coating (cataphoresis painting) to meet the minimum requirements of the atmospheric corrosivity class of C4-H (in accordance with ISO 12944). Initially, the Taguchi method was used to investigate the effects of process parameters on the response and reduce the number of parameters. Then response surface methodology – RSM – was utilised for modelling a mathematical relationship between the process parameters and the response, namely dry film thickness (DFT). Optimisation was performed to meet the minimum 75 micrometre DFT requirement. The results indicate that the RSM provides reliable quality achievement.

通过实验设计优化静电粉末涂装工艺

摘要 拖拉机驾驶室的涂装工艺在工业上是通过静电粉末涂装技术进行的，该技术是将粉末静电喷涂到驾驶室的金属部件上，需要进行保护涂层。该工艺确保在电子涂层（电泳涂装）上应用粉末涂料，以满足 C4-H 大气腐蚀性等级（符合 ISO 12944）的最低要求。最初，田口方法用于研究工艺参数对响应的影响并减少参数数量。然后，响应面方法 - RSM - 用于模拟工艺参数和响应之间的数学关系，即干膜厚度 (DFT)。执行优化以满足最小 75 微米 DFT 要求。
