Paint spraying method

Abstract

The invention relates to the technical field of paint spraying, and particularly relates to a paint spraying method. The paint spraying method comprises the steps that step 1, cleaning operation is conducted, specifically, surface cleaning treatment is conducted on a to-be-sprayed workpiece; step 2, preheating operation is conducted, specifically, preheating treatment is conducted on paint, so that the paint is heated to the first viscosity; step 3, heating operation is conducted, specifically, after preheating is completed, the paint is pumped into a paint container of a spraying machine through a pump body and heated, so that the paint is heated to the second viscosity; step 4, spraying operation is conducted, specifically, after heating is completed, the paint is sprayed to the surfaceof the workpiece through a spraying gun on the spraying machine, and the paint spraying thickness meets the paint thickness requirement of the workpiece; and step 5, drying operation is conducted, specifically, after spraying is completed, the workpiece is put into a drying channel, so that the paint on the surface of the workpiece is solidified into a film. According to the paint spraying method,paint spraying operation can be completed without adding a cosolvent or a diluent, so that the paint using safety is improved, and the spraying efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of paint spraying, in particular to a paint spraying method. Background technique [0002] When the existing paint is in use, it is necessary to add a cosolvent or a diluent to mix it to dilute and reduce the viscosity of the paint, so as to facilitate the brushing or spraying of the paint. In the paint, there are also paints with higher viscosity. This type of paint with higher viscosity has a relatively viscous characteristic. If you want to achieve the best use effect, you need to add more additives. Solvent and Thinner Thinning for Viscosity Reduction. However, when too many co-solvents and diluents are added, it is easy to cause the problem of a decrease in the solid content of the paint, which affects the performance of the paint. harm. Contents of the invention [0003] (1) Solved technical problems [0004] In order to solve the above problems, the present invention provides a painting method, ...
