FIELD: household chemistry.SUBSTANCE: invention relates to anti-acing liquids for removal and short-term protection against formation of snow-ice deposits from the outer surfaces of civil aircraft in ground icing conditions, including glycol, surfactant, corrosion inhibitor, a complexing agent, pH regulator, an antifoaming agent. Disclosed is an anti-icing fluid containing glycol, surfactant, corrosion inhibitor or a complexing agent, Ph regulator, an antifoaming agent, where glycol is used, 60-92 wt%, the surfactant used is a technical mixture of oxyethylated monoalkylphenols- -0.5- 0.2%, as a corrosion inhibitor used is a dibasic phosphate of alkaline metal - 0.1-0.8 % or as a complexing agent used is an alkali metal-biphosphonate 0.1-0.8 %, Ph regulator is used orthophosphoric acid or alkali metal hydroxide- 0.001-0.5 %, the antifoaming agent used is polymethylsiloxane - 0.03-0.07 %, water tap - the rest.EFFECT: technical result-improvement of aerodynamic characteristics of the anti-icing fluid with simultaneous improvement of its environmental friendliness.6 cl, 1 dwg, 2 ex |
