reflects the plasticity of the material and is used to assess the stringency of the enameled wire.
1.2 rebound angle, softness
reflects the elastic deformation of the material: use it to assess the softness of the enameled wire.
1.3 The toughness of the paint film includes winding, stretching, that is, the allowable tensile deformation of the paint film without tensile deformation of the conductor.
1.4 The adhesion of the paint film includes: violent breaking, peeling, mainly to assess the adhesion of the paint film to the conductor.
1.5 The scratch resistance test of the enameled wire paint film reflects the strength of the paint film against mechanical scratches
