Problems solved by technology

[0003] In the application process of different industries, it is necessary to process aluminum into various parts of different shapes, and after the parts are processed and formed, they need to be cleaned in time, otherwise it is easy to cause corrosion, mildew, oxidation, etc., and even lead to the scrapping of parts
If washed with water, most aluminum materials containing magnesium will react chemically and cause corrosion, and if it is not cleaned with water, the residual dirt will accelerate the metal surface to absorb moisture and corrosive gases in the air and cause electrochemical corrosion
However, conventional aluminum cleaning agents are suitable for pure aluminum and a small number of aluminum alloys, and cannot be fully applied to various aluminum alloy materials. Therefore, water or conventional aluminum cleaning agents cannot meet the cleaning requirements of aviation aluminum materials.

[0055] Complex surfactants include nonionic surfactants, anionic surfactants and zwitterionic surfactants.

[0056] Wherein, the phosphorus-free cleaning aid is at least one of anhydrous sodium metasilicate, sodium benzoate, sodium citrate, sodium sulfate and sodium bic...

Embodiment 2

[0071] This example provides a multifunctional cleaning agent for aviation aluminum materials. The preparation method is: weigh each component according to the proportion, add water into the container, add a composite corrosion inhibitor to dissolve, and then add non-phosphorus cleaning aids in sequence. Agents, complex surfactants, rust inhibitors, complexing agents, solubilizers, antifungal agents and defoamers.

[0072] It is necessary to ensure that the metal corrosion inhibition system substances are fully dissolved and stirred evenly before adding other components, because there is a sufficient amount of water and the corrosion inhibition system substances can be completely dissolved and uniform in the reactor for 1 hour, and there is no need for a separate heating reaction to produce corrosion inhibitors. corrosion compound.
