Problems solved by technology

However, such warning signs cannot directly reflect the surface temperature status of pitot tubes
This will make the operator overly careful when the surface of the pitot tube is not heated, but be careless when the surface of the pitot tube is heated and be accidentally burned

Embodiment Construction

[0023] The warning sign described in the present invention may be a warning word, a warning figure or a warning symbol, or a combination of these kinds of warning signs. The warning sign 1 can be sprayed and burned on the surface of aircraft heating parts or equipment components, such as figure 1 As shown, the warning sign 1' is sprayed and burned on the surface of the pitot tube, and the warning sign 1" is sprayed and burned on the surface of the heating part of the pitot tube.

[0024] In a method embodiment of the present invention, the aircraft heating equipment part is the pitot tube of the aircraft, and the method for spraying and burning the warning sign includes the following steps:

[0025] 1) process the aircraft pitot surface 2 on which the warning sign is to be sprayed, to form a glyph surface 12 on the aircraft pitot surface 2, and form a plurality of colored depressions 11 on the glyph surface;

[0026] 2) Spraying the reversible thermochromic pigment 3 of spher...

Abstract

The invention discloses a method for spraying a warning mark on the surface of an airplane heating part or an equipment component. The method comprises the following steps of: 1) treating the surface of an airplane on which the warning mark is to be sprayed so as to form a character surface on the surface of the airplane and form a plurality of colored recesses on the character surface; 2) spraying an encapsulated reversible temperature sensing and color change paint on the character surface so as to fill paint-coated capsule particles in the colored recesses on the character surface; 3) sintering the character surface; 4) coating a protective film layer on the sintered character surface; and 5) resintering the character surface and smoothing the coated character surface after the resintering. By the method, a sprayed warning character can directly reflect the surface temperature state of the airplane heating part or the equipment component, so that operation personnel are prevented from being scalded.

Description

technical field [0001] The invention relates to a warning sign on the surface of an aircraft heating part or equipment component, in particular to a heat-sensitive warning sign on an aircraft pitot tube, and the warning sign can be used to display the surface temperature state of the pitot tube. Background technique [0002] Some equipment components of the aircraft, such as the pitot tube, are equipped with an anti-icing heating device, which plays a heating and anti-icing function during the flight of the aircraft. When the aircraft is on the ground, or before the aircraft takes off, or when the aircraft is inspected on the ground, the pitot tube of the aircraft needs to be heated. The surface temperature of the heated pitot tube can reach above 200°C. [0003] When the pitot tube is heated on the ground, its surface temperature will become very high, and if the operator is not careful, it will cause accidental burns to the operator. In addition, too high surface tempera...
