Technical field

The utility model relates to the technical field of cleaning equipment, in particular to a dust removal and cleaning device used for testing flat flexible materials.

Background technique

Flexible materials are a broad concept. Compared with rigid materials, flexible materials can stretch, bend, twist, and deform without losing performance. In practical applications, the flexible materials we commonly use are generally polymer materials, such as resins, fibers, etc. , Daily products such as clothing fabrics, plastic films, flexible electrodes, flexible sensors and so on. Before use, flexible materials need to do many performance tests, including conductivity, deformation, friction, etc. The existing flat flexible material testing devices are mostly workbenches, and the testing instruments are directly placed on the surface of the workbench.
