Embodiment 1

[0040] An ultrasonic cleaning process suitable for aluminum surfaces, the process steps are as follows:

[0041] 1) Pre-cleaning

[0042] Use hot dipping or spraying to soften, separate and dissolve the pollutants on the workpiece;

[0043] 2) rough washing

[0044] Under the action of water-based cleaning agent, ultrasonic cleaning will peel off the dirt on the surface of the workpiece;

[0045] 3) fine washing

[0046] Ultrasonic rinsing is used to wash off the residual cleaning medium on the surface of the workpiece with pure water;

[0047] 4) High pressure shower

[0048] 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

[0050] This embodiment is basically the same as Embodiment 1, on this basis:

[0051] The composition ratio of described water-based cleaning agent is as follows:

[0052] Surfactant KE-1 0.8g / l

[0053] Surfactant SDBS 2.0g / l

[0054] Surfactant NP-10 2.2 g / l

[0055] Sodium tripolyphosphate 0.5g / l

[0056] Composite corrosion inhibitor 0.8g / l

[0057] The solvent is water.

Embodiment 3

[0059] This embodiment is basically the same as Embodiment 1, on this basis:

[0060] The composition ratio of described water-based cleaning agent is as follows:

[0061] Surfactant KE-1 1.2 g / l

[0062] Surfactant SDBS 2.5 g / l

[0063] Surfactant NP-10 2.6 g / l

[0064] Zeolite 4A 0.6 g / l

[0065] Composite corrosion inhibitor 1 g / l

[0066] The solvent is water.

Abstract

The invention provides an ultrasonic washing process applicable to an aluminum surface. The process comprises the steps of 1) pre-washing, namely, softening, separating and dissolving pollutant on a component by hot dipping or spraying; 2) rough washing, namely, ultrasonically washing to enable dirt to be separated and fallen from the surface of the component under the effect of a water-based detergent; 3) fine washing, namely, ultrasonically rinsing, and washing to remove the washing medium residual on the surface of the component with pure water; 4) showering under high temperature, namely, spraying pure water under high pressure from top to bottom in all directions so as to remove pollution mediums from small blind holes and gaps, and drying with hot air; the water based detergent comprises 0.8-1.2g / l of surface active agent KE-1, 2.0-2.5g / l of surface active agent SDBS, 2.2-2.6g / l of surface active agent NP-10, 0.5-0.6g / l of builder, and 0.8-1g / l of compound corrosion inhibitor; water serves as a solvent.

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 aluminum 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. Cleani...
