The system for measuring the adhesion strength of ice coating on the material surface disclosed by the invention has a simple structure, the method is easy to operate, and the system and the method are suitable for measuring and analyzing the adhesion force of ice coating on different material surfaces in units such as plants, laboratories and the like.

Description

technical field [0001] The invention belongs to the field of ice coating measurement, and in particular relates to a system and method for measuring ice coating adhesion strength on a material surface. Background technique [0002] Icing is a wonderful natural landscape, but it is a disaster for materials exposed to outdoor atmospheric conditions for a long time, such as overhead transmission lines, aircraft wings, communication towers and other materials covered with ice will cause mechanical loads The increase will cause safety accidents such as disconnection of power transmission lines or collapse of towers, overweight or uneven load of aircraft, collapse or deformation of communication towers, etc. The use of new coatings to inhibit and reduce the adhesion strength of icing on the surface of materials will help to inhibit and alleviate the formation and growth of icing on the surface of materials, and it will also be conducive to the deicing and deicing of material surfa...
