Description

Technical Field

[0001] The utility model belongs to the technical field of diamond abrasive processing, in particular to a surface modification treatment device for diamond micro powder. Background Art

[0002] Diamond wire saw is a cutting tool made by firmly holding high-hardness and high-wear-resistant diamond abrasive grains on a steel wire matrix through electroplating. Electroplated diamond wire saw has the advantages of high cutting efficiency, low sawing force, neat sawing seams, smooth cut surfaces, high yield rate, low noise, and low environmental pollution. It is not only suitable for processing common hard and brittle materials such as stone and glass, but also particularly suitable for sawing precious hard and brittle materials such as ceramics, gemstones, and crystals. In order to improve the dispersibility of diamond micropowder and its adhesion on the metal wire, it is generally necessary to modify the diamond micropowder after chemical nickel plating before electroplating to enhance its activation and dispersibility. In the process of modification, pickling is an important surface modification step, but it still has the following disadvantages in actual use:

[0003] 1. In the surface modification treatment of diamond micropowder, the powder needs to be immersed in the pickling composite acid solution in the container for pickling treatment. During the treatment process, the diamond micropowder is usually directly contained by filter cloth, etc., so that the pickling solution can enter it, and the diamond micropowder is immersed in the pickling treatment. However, after pickling, the diamond micropowder needs to be replaced in the container and the pickling composite acid solution is removed. During the operation, multiple devices need to work together with drying, the work process is long, and the efficiency is not high enough;

[0004] 2. In the surface modification treatment of diamond powder, the pickling composite acid solution needs to be contained in a container. After the diamond powder is pickled with the pickling composite acid solution in the container, the content of the pickling composite acid solution continues to decrease. When the content of the pickling composite acid solution drops to a certain level, it is necessary to replenish the acid. However, when the content of the pickling composite acid solution in the container is too low, it can only be judged manually, which requires additional manual attention and is not convenient to use.
