Method for testing matching property of zircon salt pretreatment process and vehicle body steel plate oil product

The invention discloses a method for testing the matching property of a zircon salt pretreatment process and a vehicle body steel plate oil product, and belongs to the technical field of vehicle bodycoating. The testing method comprises the steps of coating the surface of a steel plate with an oil product, degreasing, draining for the first time, soaking and washing with water, draining for the second time, carrying out zircon salt treatment, and confirming the continuity of a water film, if the continuity of the water film is 100% during water film continuity confirmation, indicating that the oil product is qualified, and if the continuity of the water film is less than 100%, indicating that the oil product is unqualified. According to the testing method, the qualified accuracy of the zircon salt pretreatment process and steel plate oil matching test is improved to 100%, and the testing method better conforms to the actual production situation. 本发明公开了一种锆盐前处理工艺与车身钢板油品配套性的测试方法，属于车身涂装技术领域。该测试方法的步骤如下：钢板表面涂布油品→脱脂
