Embodiment 1

[0041] An ultrasonic cleaning process suitable for copper surfaces, the process steps are as follows:

[0042] 1) Pre-cleaning

[0043] Use hot dipping or spraying to soften, separate and dissolve the pollutants on the workpiece;

[0044] 2) rough washing

[0045] Under the action of water-based cleaning agent, ultrasonic cleaning will peel off the dirt on the surface of the workpiece;

[0046] 3) fine washing

[0047] Ultrasonic rinsing is used to wash off the residual cleaning medium on the surface of the workpiece with pure water;

[0048] 4) High pressure shower

[0049] High-pressure pure water spraying from top to bottom in all directions to wash the polluted medium in small blind holes and crevices, and dry with hot air;

Embodiment 2

[0051] This embodiment is basically the same as Embodiment 1, on this basis:

[0052] The composition ratio of described water-based cleaning agent is as follows:

[0053] Surfactant KE-1 0.8g / l

[0054] Surfactant AES 2.0g / l

[0055] Surfactant NP-10 2.2 g / l

[0056] Sodium tripolyphosphate 0.5 g / l

[0057] Composite corrosion inhibitor 0.8 g / l

[0058] The solvent is water.

Embodiment 3

[0060] This embodiment is basically the same as Embodiment 1, on this basis:

[0061] The composition ratio of described water-based cleaning agent is as follows:

[0062] Surfactant KE-1 1.2 g / l

[0063] Surfactant AES 2.5 g / l

[0064] Surfactant NP-10 2.6 g / l

[0065] Zeolite 4A 0.6 g / l

[0066] Polyethylene and imidazoline 1 g / l

[0067] The solvent is water.

Abstract

The invention provides an ultrasonic cleaning process for a copper surface. The process comprises the following steps of 1, precleaning, wherein contaminants on a workpiece are softened, separated and dissolved through a hot dipping or spray-washing method; 2, rough cleaning, wherein dirt on the surface of the workpiece is stripped to fall off through ultrasonic cleaning under the action of water-based cleaning agents; 3, fine cleaning, wherein ultrasonic rinsing is adopted, and cleaning media left on the surface of the workpiece are washed off through pure water; 4, high-pressure flushing, wherein high-pressure pure water spraying is carried out in an omnibearing mode from top to bottom so as to flush away contaminating media in small blind holes and clearances, and hot air drying is carried out. The water-based cleaning agents are composed of 0.8 g/l to 1.2 g/l of surface active agents KE-1, 2.0 g/l to 2.5 g/l of surface active agents AES, 2.2 g/l to 2.6 g/l of surface active agents NP-10, 0.5 g/l to 0.6 g/l of auxiliary detergent, 0.8 g/l to 1 g/l of compound corrosion inhibitor and solvent of water.

Description

technical field [0001] The invention belongs to the technical field of metal element manufacturing and processing, and in particular relates to an ultrasonic cleaning process suitable for copper surfaces. Background technique [0002] Cleaning refers to the removal of liquid and solid pollutants on the surface of the workpiece, so that the surface of the workpiece can reach a certain degree of cleanliness. Cleaning is also an intermediate auxiliary process that cannot be ignored in the heat treatment production process. All workpieces before machining and heat treatment should be processed. Otherwise, the oil stains on the surface of the workpiece before and after heat treatment will directly enter the furnace to be heated, volatilized and burned, which will easily cause air pollution in the workshop, the surface condition of the workpiece is not good, and even affect the quality of heat treatment, especially for chemical heat treatment and vacuum heat treatment.
