On December 8, 2018, the 2018 National Superhard Abrasive Testing Technology Exchange Conference hosted by the National Abrasives Quality Supervision and Inspection Center and the National Abrasives Standardization Technical Committee was successfully held in SINOMACH, more than 100 from all over the country. Experts and scholars and industry colleagues attended the meeting.
Lu Shenfeng, deputy director of the national quality inspection and expert committee of the standard committee, first delivered a speech. Later, Director Lu reported on the superhard abrasive standard system and the quality supervision and inspection of superhard abrasive products in Henan Province in 2018, and on synthetic diamond and cubic boron nitride. The reasons for the unqualified artificial diamond micropowder were analyzed, and several suggestions were put forward to strengthen the control of production process, strengthen personnel training, and conscientiously implement the inspection system.
Former Chief Engineer of Zhengzhou Sanmao Institute, Executive Deputy Director of the National Abrasives Quality Supervision and Inspection Center, and Professor Gao Bo, a professor-level senior engineer, made a report on the quality control of synthetic diamond micropowder, detailing the classification, quality and inherent characteristics of diamond micropowder. Micro-powder application demand analysis, micro-powder production quality control, micro-powder application quality control.
Professor Zhou elaborated on the concept of electroplated diamond wire saw, the main factors affecting the quality of wire saw, the application requirements of electroplated diamond wire saw, the quality and control of product and the classification and correct use of product quality inspection in the report of Diamond Micropowder Detection System. .
Chen Xuebin, Minister of the National Quality Inspection Market and Technical Service Department, shared the "Detection Method of Superhard Abrasive (Diamond) Impurity Content", and introduced magnetic susceptibility, visual method, surface impurity elements, internal impurity elements, gas elements, etc. Method for detecting the content of synthetic diamond impurities.
Minister Chen also made a report on "Testing Techniques for Plating Composition in the Process of Plating Diamond Production". The report shows that although there are many detection indicators and methods popular in the industry, the methods are not uniform, and some methods are still in the exploration stage. Finally, Minister Chen proposed to make efforts to develop relevant testing standards through the efforts of all parties.
Chen Xuewei, director of the research and development department of the national grinding quality inspection technology, explained the relationship between the sharpness of the fine powder particles and the shape parameters in four aspects: shape parameters, sharpness, wear rate, and influence of shape parameters on sharpness.
Huang Qingxiang, Manager of Jiesi Group, made a report on "Quality of Diamond Micropowder by Raman Spectroscopy", introduced the development history and main products of Jiesuo Group, successfully used Raman spectroscopy to distinguish the quality (type) of diamond micropowder, and identified diamond powder. The presence or absence of mixing has solved the dilemma faced in the detection of diamond micropowder on the market.
Zhang Yingfan, a research and development engineer of China National Quality Inspection Technology, reported on the principle of Raman spectroscopy and the application of Raman spectroscopy in the research of diamond materials such as single crystal diamond, diamond film, polycrystalline diamond composite sheet and nano-diamond, and the evaluation of the use of half-width. There are problems with diamond quality.
Li Bingwen, a research and development engineer of the national grinding quality inspection technology, made a report on the "strength of synthetic diamond/synthetic diamond micropowder". The report pointed out that at present, the national grinding quality inspection found a method for quantifying the grading of diamond micropowder and judging the quality stability of micropowder. The industry's public technology service platform, Guomao quality inspection hopes to help diamond micropowder production and use enterprises to find the most suitable parameter range, and help the quality of China's diamond micropowder.
