Description

Technical Field

[0001] The utility model relates to the technical field of diamond pickling treatment equipment, in particular to a micro-nano diamond acid treatment device. Background Art

[0002] Micro-nano diamond refers to artificial diamond with a grain size of less than 100nm. Micro-nano diamond not only has the excellent properties of diamond, but also has unique properties of nanomaterials such as small size effect, surface effect, quantum effect, etc. After the manufacture of micro-nano diamond, there are many impurities on its surface, and it is usually soaked and cleaned with an acidic solution to peel off the impurities on the diamond surface. At present, the acid cleaning equipment for micro-nano diamond generally soaks the diamond in a container and heats the acidic solution to make the impurities on the diamond surface fall off. However, in many cases, the impurities on the diamond surface are often firmly adhered. It is difficult to loosen the impurities by simply relying on soaking and heating, resulting in a small amount of impurities still adhering to the diamond surface. Therefore, those skilled in the art hereby propose a micro-nano diamond acid treatment device. Utility Model Content
