Embodiment 1

[0029] Embodiment 1: A surface treatment process for a metal display base, comprising the following steps:

[0030] Cleaning-drying-preheating-powdering-preliminary heating-surface scraping-first heating curing-surface dry grinding-soot blowing-electrostatic spraying-secondary heating curing.

[0031] Operation precautions are as follows:

[0032] Cleaning: The cleaning liquid is water, and the workpiece is manually cleaned in clean water.

[0033] Drying: Place the workpiece in the drying room to dry.

[0034] Preheating: Preheat the workpiece in an oven to a temperature 20-30°C higher than the melting point of the powder coating.

[0035] Powder application: Make the defect surface face upwards, quickly scoop the electrostatic powder with a small utensil such as an ear scoop, and partially accumulate it at the defect. Try to be precise when accumulating, and try not to exceed the defect range too much. The powder coating is applied to the surface defect of the workpiece, ...

Embodiment 2

[0044] Example 2: A surface treatment process for a metal display base, the difference from Example 1 is that in the cleaning step, the cleaning solution is mixed with water and a surfactant at a ratio of 10:1, and the surface The active agent is glyceryl monostearate.

Embodiment 3

[0045] Embodiment 3: A surface treatment process for a metal display base, the difference from Embodiment 2 is that the surfactant is cocoyl glucoside.

Abstract

The invention relates to the field of metal products, and particularly discloses a surface treatment process of a metal display screen base, which comprises the following steps: cleaning, drying, preheating, powdering, primary thermal drying, surface scraping, primary thermal drying and curing, surface dry grinding, soot blowing, electrostatic spraying and secondary thermal drying and curing. The problem that the performance of a powder coating film is poor due to defects of the surface of a workpiece can be solved.

Description

technical field [0001] The application relates to the field of metal products, more specifically, it relates to a surface treatment process for a metal display base. Background technique [0002] The display base is a component located at the bottom of the display to support the display, which is generally made of metal or metal alloy. In the production process, the metal alloy is made by casting in the early stage and surface treatment in the later stage. [0003] The post-surface treatment process of the display base is mainly: the surface treatment is realized by powder coating electrostatic spraying on the component. However, the surface treatment effect of electrostatic spraying will be affected by the defects of the workpiece itself, mainly reflected in the pits formed by scratches, extrusion, bumps, corrosion, spot welding, riveting, etc. of the workpiece itself, as well as the sand holes exposed after casting processing, Porosity, porosity, fine knife lines after m...
