Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the specific embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0038] The invention provides a technical solution: a production integrated spraying process, comprising the following steps:

[0039] A. Workpiece cleaning;

[0040] B. Primer spraying;

[0041] C. Topcoat spraying;

[0042] D. The workpiece is dried.

[0043] Workpiece cleaning in step A includes the following steps:

[0044] A1, alkali washing

[0045] Set the workpiece to be sprayed in an alkali tank with a mass concentration of 10% to 20% NaOH solution, wash and degrease with alkali for 5 to 15 minutes, and then place the alkali solution in a cold water tank at room temperature to clean the surface of the workpiece Clean and remove organic matter on the surface...

Abstract

The invention discloses a production integrated spraying process, and relates to the technical field of integrated spraying. The production integrated spraying process specifically comprises the following operation steps of A, workpiece cleaning; B, primer spraying; C, finish paint spraying; and D, workpiece drying. According to the production integrated spraying process, integrated assembly linemanagement is achieved through the four procedures of the workpiece cleaning, the primer spraying, the finish paint spraying and the workpiece drying, the spraying efficiency is improved, the two steps of alkali washing and acid washing in the workpiece cleaning process are beneficial to removal of organic matter and oxide on the surface of a workpiece, rust removal, oil removal and dirt removal are achieved, subsequent spraying operation is facilitated, two spraying procedures of primary finish paint spraying and secondary finish paint spraying are set in the finish paint spraying process, the front face of the workpiece can be comprehensively sprayed through the primary finish paint spraying, multiple edges or dead corners of the workpiece can be sprayed through the secondary finish paint spraying, a repeated continuous turning-over spraying mode is adopted, and the phenomenon of spraying missing does not likely to happen.

Description

technical field [0001] The invention relates to the technical field of integrated spraying, in particular to a production integrated spraying process. Background technique [0002] Spraying is a coating method in which spray guns or disc atomizers are dispersed into uniform and fine droplets by means of pressure or centrifugal force and applied to the surface of the object to be coated. It can be divided into air spraying, airless spraying, electrostatic spraying and various derived methods of the above basic spraying forms, such as large flow and low pressure atomization spraying, thermal spraying, automatic spraying, multi-group spraying, etc. [0003] In the spraying process of the existing workpieces after production, the corners of the workpieces need to be sprayed manually. The spraying efficiency is low and it is easy to miss spraying. However, the general integrated spraying process cannot realize the combination of primer and topcoat at one time. All spraying opera...
