Benefits of technology

This patented process produces an oil that makes it easier to clean up any dirt on surfaces like frostings during flight. Its properties are excellent with regards to its ability to stick well onto these materials without causing them to lose their appearance overtime due to water evaporation from moisture condensation caused when they get wet again after being used repeatedly. Additionally, this new material doesn't harm our health if exposed to sunlight because it won’ts no bad smell even at high temperatures. Overall, this process provides technical benefits such as improved visibility, reduced glare, less pollution, environmental friendliness, lower costs compared to existing methods, ease of use, etc., making it ideal for various applications where precise data acquisition needs have been achieved through optical techniques.

Problems solved by technology

This patents describes two technical problem areas related to airplanes' operation that are being threatened with getting snow from inside outdoors due to factors like rainwater damage caused by precipitation during winter months. These issues include deformation of wing surfaces (frost) made up mostly of water droplets when they freeze), changes in altitude affecting flying height, and potential hazards associated with accumulation of moisture near critical points where condensation occurs. There may also occur situations involving ice formation over certain types of structures called runways, leading to accidents causing delays and reduced passenger comfort levels. Therefore there needs better ways to accurately measure these conditions without damaging them themselves while minimizing costs.

Abstract

The present invention belongs to the technical field of aircraft icing ice-shaped measurement, and especially relates to a developing agent for aircraft icing ice-shaped three-dimensional scanning anda preparation method thereof. The developing agent comprises TiO2 powder, PMMA powder and a dichloromethane solvent. The preparation method comprises the steps of: pouring the TiO2 powder and the PMMA powder into a beaker, pouring dichloromethane into the beaker along a beaker wall by employing a measuring cylinder, and performing pre-stirring with pouring to obtain pre-mixed solution; and employing a ball-milling blender to perform stirring of the pre-mixed solution to make the developing agent. The problem is solved that the ice-shaped light transmittance is too high and cannot meet the laser three-dimensional scanning requirement, the provided developing agent has good adhesive force for the ice shape so that the ice-shaped light transmittance is greatly reduced, light shielding effectduration is long, secondary icing or ice melting cannot be caused, the developing agent for aircraft icing ice-shaped three-dimensional scanning is environmentally friendly and low-toxic, easy to spray, and has a very important practical significance for promotion of the application of the laser three-dimensional scanning technology at the aircraft icing ice-shaped three-dimensional measurement technology.
