Problems solved by technology

[0004] The technical problem to be solved by the present invention: Aiming at the disadvantages that the current deicing and anti-icing liquid has a short duration and cannot achieve long-term deicing effect after use, resulting in a large consumption, a kind of combination of guar beans and homemade Seedling-raising substrates are mixed, and the active substances are catalyzed by the enzymes in the germination process of guar beans, and then the germinated guar beans are steamed and left to mold. Under acidic conditions, the active substances in the guar beans are extracted and concentrated by rotary steaming. The concentrated solution is used as a thickener and a surfactant component, and then mixed evenly with ethylene glycol, propylene glycol, etc. to prepare a long-acting aircraft deicing and anti-icing fluid

Abstract

A preparing method of a long-acting airplane deicing and anti-icing fluid is disclosed and belongs to the technical field of airplane deicing and anti-icing fluid preparation. The fluid is prepared by mixing guar seeds with a self-prepared seedling culturing matrix, generating active compounds by utilizing enzyme catalysis itself in a guar seed germination process, steaming the germinated guar seeds, then allowing the seeds to stand and mildew, extracting the active compounds in the guar seeds under acidic conditions, performing rotary concentration to obtain a concentrate liquid that is adopted as a thickener and surfactants, and fully mixing the concentrate liquid with glycol, propylene glycol, and the like. Beneficial effects of the method are that preparation steps are simple; the lasting time of the prepared fluid is prolonged by 40-50 min than that of other deicing and anti-icing fluids; and the fluid is safe, environment friendly, pollution-free, and low in corrosion to airplane body materials and airport runways, can ensure safe landing and taking off of airplanes in winter and can be popularized and applied in a large scale.

Description

technical field [0001] The invention relates to a preparation method of a long-acting aircraft deicing and anti-icing fluid, belonging to the technical field of aircraft deicing and anti-icing fluid preparation. Background technique [0002] Our country has a vast territory and a large span from north to south. The climate conditions of various airports are very different. Except for a few airports in southern regions such as Guangdong, Guangxi, and Fujian, it rarely snows, and airports in Northwest, Northeast, and North China often experience snow in winter. It is a long period of ice and snow, and the ground and the surface of the aircraft fuselage are prone to ice, frost and snow accumulation. When the frost and snow are attached to the fuselage, wings and control surfaces of the aircraft, the surface of the aircraft will be rough, causing changes in those parts of the aircraft that generate lift, which will damage the smooth aerodynamic efficiency and lift of the wings, ...
