Problems solved by technology

[0014] Due to the strong shear force caused by high-speed stirring, pumping and conveying through small pipelines, the thickener will experience irreversible viscosity loss. This mechanical transport will destroy the polymer chain and even cause damage to the polymer network structure. irreversible damage

Abstract

The invention relates to novel airplane de-icing / anti-icing liquid and a preparation method thereof. The de-icing / anti-icing liquid consists of de-ionized water and the following ingredients in percentage by weight: 30 to 80 percent of dibasic alcohol, 0.01 to 1.0 percent of thickening agents, 0.05 to 2 percent of surface active agents, 0.01 to 1 percent of corrosion inhibitors and 0.05 to 0.2 percent of antimicrobial agents, and the pH is 7.0 to 7.5. The airplane de-icing / anti-icing liquid is mainly used for clearing condensed settlings such as ice, snow, frost and the like formed on the airplane surface when an airplane stops on the ground, and new snow, ice or frost can be prevented from being formed on the airplane surface through the further accumulation.

Description

technical field [0001] The invention relates to the aerospace field, in particular to a novel aircraft de-icing / anti-icing liquid. Background technique [0002] Aircraft de-icing / anti-icing fluid is mainly used to remove condensation deposits formed on the surface of the aircraft when the aircraft stays on the ground, such as ice, snow, frost, etc., to prevent further deposition of new snow, ice or frost on the surface of the aircraft. [0003] The main difference between anti-icing and de-icing is that anti-icing mainly prevents the formation of ice; de-icing removes the ice that has formed to speed up the cleaning of the aircraft surface. [0004] Aircraft de-icing / anti-icing fluids are very important in treating aircraft surfaces. After entering winter, the surface of the aircraft will be covered with a layer of frozen material, and the deicing / anti-icing fluid will remove this layer of frozen material from the aircraft wing through the shear force formed by the sudden i...
