The device comprises a base, a temperature sensor, a circuit switching device, a lower particle carrier, a sensor magnetic core, a displacement sensor, a lever bracket, a lever arm, a hook, an upper particle carrier, a microscope centralizing body, an HD electron microscope, a trimming platform, a lifting platform, a level bubble, a leveling knob, a constant-temperature heating device, a control panel, a torsion wire and a torsion wire connecting frame; the circuit switching device, the lifting platform and the level bubble are fixedly connected to the base; the temperature sensor and the constant-temperature heating device are fixedly connected to the circuit switching device; the lower particle carrier is hung on the hook. The device is reasonable in structure, is suitable for testing the particles with radius of 250 micrometers to 5 millimeters, overcomes the influence of temperature changes on the tensile force between two particles, and shoots the change process before and after the contact of the two particles through the HD electron microscope so as to facilitate theoretical analysis.

Description

technical field [0001] The invention relates to a test device, in particular to a micro tension test device between two viscous particles. Background technique [0002] The current micro-pulse test process between two particles is cumbersome, and the structure used is relatively complicated. It cannot overcome the influence of temperature changes on the micro-tension between two particles, and cannot record the change process of two particles before and after contact, which is inconvenient. theoretical analysis. Contents of the invention [0003] The present invention aims to solve the above problems, and provides a device for micro-tension testing between two viscous particles, which overcomes the disadvantages of cumbersome testing process, complex structure, and inconvenient analysis between two viscous particles. as follows: [0004] A micro tension test device between two sticky particles, including a base, a temperature sensor, a circuit conversion device, a lower ...
