Cleaning agent for aircraft pipelines and preparation method thereof

Abstract

The invention relates to the field of aviation and specifically relates to a cleaning agent for aircraft pipelines and a preparation method thereof. The cleaning agent comprises an organic acid, a corrosion inhibitor, a surfactant, auxiliaries and deionized water, wherein the organic acid is a complex organic acid, the complex organic acid comprises an aminosulfonic acid and an organic acid with a low pH buffer value, and the complex organic acid accounts for 8-20% by weight of the total cleaning agent; in order to further improve the pH buffer capacity of the cleaning agent and improve the proportion of the organic acid with the buffer function in the complex organic acid to keep the high efficiency in descaling of the cleaning agent, the proportion of the complex organic acid to the aminosulfonic acid in parts by weight is (25-50): (75-50). By adding the high-efficient corrosion inhibitor in the formula, the corrosion to metal materials caused by the acid is greatly reduced, so that the safety of aircraft materials is ensured.

Description

technical field [0001] The invention relates to the field of aviation, in particular to a cleaning agent for aircraft pipes and a preparation method. Background technique [0002] When the water-insoluble organic substances and calcium compounds produced by the decomposition of human excrement adhere to the inner wall of the sewage pipe and the inner wall of the water pipeline will form a layer of hard sediment during the long-term water delivery process, the sediment will fade after a long time will become fouled. The increase of fouling not only affects the flow of water in the pipeline, but also makes the inner diameter of the pipeline gradually smaller, and even blocks the pipeline, causing adverse effects. For example, the blockage of the aircraft sewage pipeline will cause the toilet connected to the pipeline to be unable to use normally, causing peculiar smell in the aircraft toilet, affecting the normality of the flight and the comfort of passengers. Generally spea...

Problems solved by technology

[0010] In order to overcome the problems that existing cleaning agents for aircraft pipelines cannot be compatible with various metal material pipelines, are corrosive and irritating to pipelines, and have low cleaning efficiency due to low pH buffer capacity, a special cleaning agent is now proposed. It is used to remove scale and scale in aircraft pipelines. It is a cleaning agent for aircraft pipelines that is less corrosive to the material of the pipeline system, has high pH buffer capacity, high cleaning efficiency, is not easy to volatilize during the cleaning process, and is non-irritating to human skin.
