This article will introduce in detail the definition, working principle, application fields and related technical parameters of the low-temperature folding endurance testing machine.
1. Definition of low temperature folding endurance testing machine
The low-temperature folding endurance testing machine is a testing device that simulates repeated folding or bending of materials in a low-temperature environment. By setting a specific temperature and the number of folds, it can detect the folding endurance, fatigue resistance, and changes in physical properties at low temperatures of the material. This equipment is widely used in rubber, plastics, textiles, metal materials and other industries.
2. Working principle
The working principle of the low temperature folding endurance testing machine mainly includes the following steps:
1.Sample placement: Fix the material to be tested on the fixture of the testing machine.
2.temperature control: Reduce the test environment to a set low temperature (usually -40℃ to -70℃) through the refrigeration system.
3.Folding test: The material is repeatedly folded or bent through a mechanical device, and the number of folds and changes in the material are recorded.
4.data logging: The equipment automatically records the number of fractures, surface cracks and other data of the material, and generates a test report.
3. Application fields
Low temperature folding endurance testing machines are widely used in the following industries:
