Coating technology for engineering dumper container

Abstract

The invention provides a coating technology for an engineering dumper container, comprising the steps of pre-degreasing, degreasing, rinsing, surface conditioning, phosphorizing, rinsing, drying the water, spraying primer, drying, spraying finish paint, drying and cooling, and spraying and drying twice after integrally phosphorizing the engineering dumper container. The coating technology is used for solving the problem of integrally phosphorizing the engineering dumper container, and sprays and dries twice while phosphorizing, is characterized by low investment, small occupied area, low cost for operation and maintenance, feasible and simple process, and improves high quality of the product, and reduces producing cost, and the like.

Description

technical field [0001] The invention relates to a new coating process for cargo boxes, in particular to a coating process for automotive engineering cargo boxes, which belongs to the automobile manufacturing industry. Background technique [0002] At present, the known coating process of the cargo box of the self-unloading engineering vehicle is: derusting the surface of the cargo box, degreasing the surface of the cargo box with gasoline, drying the surface of the cargo box naturally, spraying anti-rust primer, drying the primer, Spray the container topcoat and dry the topcoat (two-spray and two-dry process). The process uses gasoline, which is prone to fire and has serious safety hazards. In this process, there are too many manual processes, the quality is difficult to control, and the production efficiency is low. It is difficult to achieve large-scale production and the production cost is high. And it is greatly affected by the weather and the site. When the container p...
