Method for spraying surface of engineering machinery covering part

Abstract

The invention provides a method for spraying the surface of an engineering machinery covering part. Before a complete machine is assembled, spraying of parts covering the surface of a machine body is finished, and assembling of the complete machine is then performed. The method for spraying the surface of the engineering machinery covering part includes the specific steps of surface preprocessing, primer spraying, primer drying, puttying, finish paint spraying, finish paint drying and polishing. The method is characterized in that a corrosion-resisting coating is sprayed after surface preprocessing and before primer spraying. According to the method for spraying the surface of the engineering machinery covering part, the spraying efficiency of the covering part can be improved, the spraying quality is guaranteed, the dosage of primer is reduced, and the number of times of spraying finish paint is reduced.

Description

technical field [0001] The invention relates to a method for spraying the surface of a cover, in particular to a method for spraying the surface of an engineering machinery cover. Background technique [0002] Construction machinery is a kind of machinery that works outdoors. It has been exposed to harsh environments such as outdoor atmosphere and different water quality for a long time, and is subject to different degrees of corrosion in different regions and environments all the time, resulting in various " chronic disease" and "frequent disease". Construction machinery surface spraying is an important link in the manufacturing process of construction machinery products. The quality of anti-rust and anti-corrosion spraying is one of the important aspects of the overall quality of the product. The appearance quality of construction machinery not only reflects product protection and decoration performance, but also is an important factor that constitutes product value. In...

AI Technical Summary

Problems solved by technology

In the actual production and use of construction machinery products, often because the surface spraying quality of construction machinery covering parts is unqualified, resulting in surface damage such as paint film peeling off or scratches on the surface of construction machinery product covering parts, these surfaces need to be reworked and cost a lot of money time and production costs, resulting in unnecessary losses

Similarly, the surface spraying of construction machinery covering parts only pays attention to the appearance, but despises the inner quality of the bottom layer. As a result, a series of problems such as surface coating peeling, corrosion, acidification, etc. occur during use, which seriously affects the construction machinery operation and construction machinery manufacturers. reputation
