Abstract

The invention discloses a testing device for the vertical bonding strength of ice layers on the surface of a material and a testing method thereof. The method comprises the following steps: firstly preparing the ice layers with equal volume and equal contact area by utilizing a conical drum in the testing device, and then peeling the ice layers by utilizing a drawing device to lift the conical drum; reading the maximum normal force in the peeling process and representing the vertical bonding strength of the ice layers on the surface of the material by utilizing the ratio of the maximum normal force to the contact area of the ice layers and a sample. The testing device and the testing method disclosed by the invention can be used for testing the vertical bonding strength of the ice layers on the surfaces of multiple materials, coating layers and natural organisms and on the surface of a special wettability sample, provides a simple and effective evaluation method and means for material and coating-layer selection and the surface modification technology in engineering and also provides a good representation means for scientific research simultaneously.

Description

technical field [0001] The invention relates to a test device for the strength of ice layers on the surface of metal materials, coatings, natural biological materials and special wettability surfaces, in particular to a test device and a test method for the vertical bonding strength of ice layers on the surface of materials. Background technique [0002] In nature, icing is a beautiful natural landscape that can bring visual enjoyment to human beings, but it also often causes inconvenience and even disasters to people's daily life and practical engineering. For example, in the power system, the bare aluminum conductors of high-voltage overhead transmission will be covered with ice in a certain atmospheric environment. When the transmission wire is seriously iced, disasters such as line tripping, wire galloping, line breakage, transmission tower collapse, insulator flashover, and communication interruption will occur. Icing on different parts of the aircraft surface will lea...
