Abstract
The invention relates to a test device, in particular to a micro tension test device between two viscous particles. Including base, temperature sensor, circuit conversion device, lower particle carrier, sensor magnetic core, displacement sensor, lever frame, lever arm, hook, upper particle carrier, microscope centralizer, high-definition electron microscope, fine-tuning platform, lifting platform, level bubble, The leveling knob, the constant temperature heating device, the control panel, the torsion wire, the torsion wire connecting frame, the circuit conversion device, the lifting platform and the level bubble are fixedly connected to the base, and the temperature sensor and the constant temperature heating device are fixedly connected to the circuit On the conversion device, the upper particle carrier is hung on the hook. Beneficial effects: reasonable structure, suitable for testing particle radius range: 250 μm ~ 5mm, overcomes the influence of temperature changes on the micro tension between two particles, high-definition electron microscope photographs the change process of two particles before and after contact, which is convenient for 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 ...
