In order to promote the quality improvement of super-abrasive products and industrial transformation and upgrading, and improve the quality control level of raw materials for super-abrasive downstream enterprises (wire saws and other super-hard materials products enterprises), the National Abrasives Quality Supervision and Inspection Center organized “Super†in Zhengzhou, Henan. Hard abrasive testing technology exchange meeting." The conference focused on superabrasive testing technology, and exchanged and discussed various problems arising during the use of superabrasives, providing practical technology and value information for related companies.
I. Technical exchange content
The technical exchange meeting is divided into five major themes, namely (1) "standard system"; (2) "quality control of diamond micropowder loose material"; (3) "exploration of the strength of synthetic diamond / synthetic diamond micropowder"; (4) "Method of testing diamond plating"; (5) Establishment of quality inspection system for diamond wire saw.
The details are as follows:
(1) Standard system
1. Theme: Introduction to Superhard Abrasive Standard System
Focus of attention: introduction of superhard abrasive standard system, supervision and spot check introduction.
Lu Shenfeng, deputy director of the National Abrasives Quality Supervision and Inspection Center, technical leader, and expert member of the Abrasives Standards Committee.
(II) Quality control of diamond micropowder
2. Theme: Quality Control of Synthetic Diamond Micropowder (Wire Saw Direction)
Focus of attention: For the diamond micropowder used in wire saws, after the outbreak in 2017, it will calm down in 2018. More and more manufacturers put forward higher requirements for the quality of micro-powder, how to meet the application requirements of wire saw enterprises, and which indicators affect the application of wire saws? This topic will be shared for you.
Former deputy chief engineer of Zhengzhou Sanmao Institute, former deputy director of the National Abrasives Quality Supervision and Inspection Center, and professor-level senior engineer Zhou Bo
3. Subject: Test Method for Superhard Abrasive (Diamond) Impurity Content
Focus: The impurity content of synthetic diamond/synthetic diamond powder has always been the focus of attention in the industry. The diamond impurity content in the industry usually refers to ash, surface impurities and internal impurities. What is the difference between these impurities? How to test?
4. Discussion on the Characterization of Sharpness of Micronized Particles
Focus: How is the sharpness of the particles defined? Related to those parameters? This is the focus of consistent attention in the industry. This sharing will combine the wear rate with the sharpness from the theoretical source to explore a convenient and feasible method to characterize the sharpness of the particles.
National Abrasives Quality Supervision and Inspection Center Senior Engineer Chen Xuewei
(III) Discussion on the "strength" of synthetic diamond/synthetic diamond powder
5. Application of Raman spectroscopy in diamond
Focus of attention: Raman spectroscopy principle, which can be used to characterize the performance of diamond, how to apply it to diamond detection.
6. Discussion on the "strength" of synthetic diamond/synthetic diamond powder
Focus of attention: the basis of synthetic diamond classification; the relationship between the first type, the second type and the third type which are common in the market and the current standard; the definition of the "strength" of the synthetic diamond powder; the discussion of the "good or bad" of different diamond powders; At present, the national quality inspection work report.
(4) Detection of plated diamond powder
7. Nickel-plated diamond powder detection
Focus: In diamond plating, nickel plating is the most common and the most widely used. (1) How to control the stability of the plating liquid composition during the nickel plating process, this sharing will start from the detection method of the plating liquid composition, how to adjust/control the plating liquid composition according to the test data for exchange; (2) Nickel-plated diamond quality control The standard is missing and the detection methods are not uniform. How to detect the quality of nickel-plated diamond powder, what are the indicators worthy of attention?
(5) Diamond wire saw quality inspection system
8. Theme: Diamond wire saw quality inspection system
Focus: The quality inspection system for diamond wire saws is not perfect. It can only reflect the quality of products through application, which leads to an increase in research and development costs. In severe cases, customers lose trust. How to check the quality of the product?
Invited to invite: former deputy chief engineer of Zhengzhou Sanmao, former deputy director of the National Abrasives Quality Supervision and Inspection Center, and professor-level senior engineer Zhou Bo.

Xenon Arc Lamp Aging Test Chamber
A Xenon Arc Lamp Aging Test Chamber is a specialized testing equipment used to simulate the aging effects of sunlight on various materials and products. It is commonly used in industries such as automotive, aerospace, and textiles to evaluate the durability and performance of materials under prolonged exposure to sunlight.
The chamber consists of a xenon arc lamp, which emits a broad spectrum of light similar to sunlight, and a sample holder where the materials or products to be tested are placed. The lamp emits high-intensity light, including ultraviolet (UV), visible, and infrared (IR) radiation, which can be adjusted to simulate different weather conditions and intensities of sunlight.
The test chamber is designed to control various parameters such as temperature, humidity, and light intensity to accurately replicate real-world conditions. It can simulate different weather conditions, such as sunlight, rain, and humidity, to assess the effects of these conditions on the materials being tested.
By subjecting materials to prolonged exposure in the Xenon Arc Lamp Aging Test Chamber, manufacturers can evaluate the effects of sunlight on color fading, material degradation, cracking, peeling, and other forms of deterioration. This information helps them make informed decisions about the selection of materials and determine the expected lifespan of their products.
Overall, the Xenon Arc Lamp Aging Test Chamber is an essential tool for quality control and product development in industries where prolonged exposure to sunlight can impact the performance and durability of materials and products.
