Abstract

The invention belongs to the technical field of measurement, and discloses a measuring device for measuring adhesion of surface icing of a material. The device comprises a measuring system and a low temperature icing system. The measuring system comprises a computer data acquisition module, a lifting and fixing platform, a stepping motor, a weighing sensor and a drive shaft; the low temperature icing system includes an external water gun, an environmental box, an icing sleeve, a fixing fixture and a sample to be tested. The stepping motor is disposed above the lifting and fixing platform, andthe stepping motor is connected to the lifting and fixing platform through screws. The weighing sensor is arranged on the right side of the stepping motor, and the weighing sensor is tightly connectedwith the stepping motor through a fastening screw. The device is suitable for various types and multiple sizes, and high in precision, and is icing adhesion testing equipment with excellent controllability. The device is especially suitable for testing surfaces such as hydrophobic coatings with anti-icing properties, and has high test accuracy and controllability.

Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to a measuring device for measuring the ice-covered adhesion force on the surface of a material. Background technique [0002] At present, icing is a common natural phenomenon in nature. However, icing on key parts of equipment such as aircraft, radar, power transmission lines, and high-speed trains may cause certain safety hazards and even cause major accidents. Therefore, in recent years, more and more scientific researchers start with the preparation of anti-icing coatings, and carry out anti-icing work by delaying the freezing time, inhibiting the accumulation and growth of ice crystals, and reducing the adhesion of ice on the surface of materials. In terms of the means of characterizing the anti-icing performance of the material surface, the test of the freezing time and the amount of ice coating can be done very accurately, but there is still no quantitative st...
