[0036] As an optimization of the above technical solution, it further includes a positioning structure. The positioning structure includes a positioning shaft 5. A positioning through hole 16 that penetrates through from front to back is provided on the support block 11. The positioning shaft 5 penetrates through the positioning through holes 16 on the first sample preparation rack 1 and the second sample preparation rack 2.

[0037] In the above technical solution, the first sample preparation rack and the second sample preparation rack can be fixedly connected by the positioning shaft and the bolt rod.

[0038] As an optimization of the above technical solution, the notch 13 is provided at the middle position of the end edge of the support platform 12.

[0039] As an optimization of the above technical solution, the thickness of the support platform 12 is 0.5 - 3 mm; preferably, the thickness of the support platform 12 is 1 mm or 2 mm.

[0040] Reflection method: The slicing sample preparation rack (1 & 2 mm) can both be used.

The excess soft plastic packaging film beyond the bottom of the sample preparation rack does not need to be sliced.

[0041] Transmission method: Only the slicing sample preparation rack (1 mm) can be used. The excess soft plastic packaging film that is higher than the upper plane of the sample rack and beyond the bottom of the sample preparation rack all need to be sliced for cross-section treatment of the sample. If necessary, the cross-section of the sliced sample can be dyed to facilitate the quick qualitative identification of the materials of each layer of the composite soft packaging film under the metallurgical microscope using the transmission method.

[0047] The usage principle of the sectioning sample preparation rack of the present utility model is as follows:

[0048] S1: Use a small hexagon screwdriver to loosen the 2 bolt rods on the side of the sectioning sample preparation rack;

[0049] S2: Put a small piece of soft plastic packaging film into the middle of the sectioning sample preparation rack and clamp it. It is recommended that the soft plastic packaging film be placed at the position straddling the middle circular hole of the sectioning sample preparation rack. On the one hand, the middle circular hole position can be used as a reference point for quickly finding the sample under the microscope later. On the other hand, since the sample at the middle circular hole position is not physically clamped, it is not easy to cause problems with inaccurate thickness of each layer of material due to material deformation;

[0050] S3: Tighten the 2 bolt rods on the side of the sample preparation rack. If the sample cannot be clamped tightly, use a hexagon screwdriver to assist in tightening and clamping the sample. Pay attention to the clamping force of the sample to prevent the sample from being deformed by clamping, and then sectioning can be started;

[0051] Reflection method: Both the sectioning sample preparation racks (1 & 2 mm) can be used. The soft plastic packaging film only needs to be about 1 cm higher than the upper plane of the sample rack for cross-section sectioning of the sample. The excess soft plastic packaging film beyond the bottom of the sample preparation rack does not need to be sectioned;

[0052] Transmission method: Only the sectioning sample preparation rack (1 mm) can be used. The excess soft plastic packaging film higher than the upper plane of the sample rack and beyond the bottom of the sample preparation rack all need to be sectioned for the cross-section of the sample. If necessary, the cross-section of the sectioned sample can be stained to facilitate rapid qualitative identification of the materials of each layer of the composite soft packaging film under a metallurgical microscope using the transmission method;

[0053] S4: After sectioning is completed, the sample preparation rack can be directly placed under the metallurgical microscope together with the sectioned sample. Observe the cross-section of the soft plastic packaging film sectioned sample using the reflection method or the transmission method, and use the software of the metallurgical microscope to measure the thickness of each layer of material of the soft plastic packaging film under the microscope;

[0054] S5: After the test is completed, if no other chromogenic reagents are used to stain the cross-section of the section sample, directly loosen the two bolt rods on the side of the transmission section sample holder, and remove the tested sample. If there is a staining treatment, it is necessary to immediately clean this section sample holder with absolute ethanol to avoid corrosion and rust of the section sample holder;

[0055] S6: If it is found that the section sample holder is corroded and rusted, the bolts and the positioning shaft screws on the side of the section sample holder can be loosened, and rust removal and cleaning can be carried out with absolute ethanol. After cleaning, tighten the bolt rods and the positioning shaft screws.

[0056] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
