Description

Technical Field

[0001] The utility model relates to the technical field of detection and analysis, in particular to a plastic cold-mounting mold that does not require chamfering. Background Art

[0002] Using embedding materials (such as epoxy resins and curing agents) to prepare powdered or bulk samples into reflectance films of specific specifications for analysis using instruments such as light and electron microscopes is a fundamental method for studying the fundamental properties of materials and is widely used in research fields such as metallurgy and mineralogy. Typically, to determine mineral composition and elemental occurrence, the sample must be ground into a powder of appropriate particle size and then qualified reflectance films must be prepared. However, to observe parameters such as mineral embedding characteristics and intergrowth relationships, which reflect mineral microstructure and crystal properties, bulk mineral samples are typically mounted directly and then qualified reflectance films must be prepared for observation. Whether manual or automated, polishing involves the continuous removal of scratches on the mineral surface, ultimately rendering the mineral crystal faces visible and meeting observational requirements. Bulk rock and mineral samples, due to their larger exposed mineral surface, are more difficult to polish than powdered samples. The polishing process is particularly susceptible to scratches, particularly those caused by sharp edges on the sample surface. These scratches on the polishing consumables during the polishing process can severely impact the final sample and image quality. Although manual pre-chamfering can be used to remove sharp edges, this can still pose unavoidable safety risks and result in poor sample quality. Therefore, a plastic cold mounting mold that does not require chamfering is needed. This can avoid the safety risks associated with manual chamfering and efficiently produce qualified reflectance films of block rock and mineral samples. Utility Model Content
