一、前言随着我国涂料工业特别是水性漆的飞跃发展,要求测试涂料性能的项目也日益增多,需要研制多种新的测试仪器,以满足生产和科研上的需要。因此,提出了库仑计的研制任务。水溶性电泳漆是通过电场的作用将涂料颗粒(实质上是一些带电离子)泳到工件上,从而完成了在工件上涂装涂料的过程。在此过程中,涂料物质被涂装到工件上是由于电场的作 I. Preface With the rapid development of paint industry in our country, especially water-based paint, there are more and more projects requiring testing of coating properties. We need to develop a variety of new test equipment to meet the needs of production and scientific research. Therefore, the development of Coulomb counter is proposed. Water-soluble electrophoretic paint through the role of the electric field of paint particles (in essence, some charged ions) swim to the workpiece, which completed the coating process on the workpiece. During this process, the coating material is applied to the workpiece due to the electric field
