Abstract

A coating technology for car includes such steps as cleaning surface, pre-removing oil, removing oil, washing with purified water, conditioning surface, phosphorizing, washig with purified water again, passivating, washing with deionized water, electrophoresis, washing with UF solution twice, and washing with deionized water again.

Description

Technical field: [0001] The invention belongs to the technical field of automobile production technology, and in particular relates to an automobile painting production technology. Background technique [0002] Usually, in the painting process of automobile body, the mechanized process of the body has always been the main production artery of the paint shop, and the pre-treatment and electrophoresis conveying equipment need to withstand the continuous erosion of acid, alkali and organic solvent due to the poor working environment. Continuous operation for a long time in a high temperature and high humidity environment has high requirements for the selection of conveying equipment. The traditional process is a set of mechanized conveying procedures that are widely used in the automotive industry for pre-painting treatment and electrophoretic conveying equipment. It has many advantages such as plane conveying, vertical lifting, spreader swing, accumulation storage and so on. ...
