When performing X-ray inspection on high-density insulating cardboard, it is necessary to ensure that the equipment parameters are set accurately, the test piece is placed stably and accurately, so as to obtain a clear X-ray image. By interpreting and analyzing the image, it can be determined whether there are defects inside the insulating cardboard, such as cracks, surface or internal metal foreign matter, etc. X-ray inspection is a non-destructive inspection technology that can be carried out without destroying the test piece, so it is widely used in the quality inspection of materials such as insulating cardboard.
