Yancheng County guides quality innovation and creates national superhard material brand

Yucheng County Industrial Cluster is the “National Superhard Material and Product High-tech Industrialization Base” with the highest industrial cluster of synthetic diamond (micronized powder) and the most complete industrial chain. The Henan Provincial Synthetic Diamond Micropowder Quality Supervision and Inspection Center, which stands in the superhard material industry group in Yucheng County, obtained the inspection quality of the provincial quality inspection center on December 1, 2015. It is the only provincial quality inspection in China. mechanism. Its important mission is to guide the innovation drive in this field and win by quality.

Scientific and technological innovation, standard innovation, management innovation, and enhance the core competitiveness of diamond micropowder products in domestic and foreign markets
Zhou Bo, the chief expert and professor-level senior engineer of Henan Province Synthetic Diamond Micro-powder Quality Supervision and Inspection Center, recently visited the provincial-level quality inspection technology public platform to comment on the current international and domestic synthetic diamond micro-powder products market. Vertical and horizontal, in one sentence: "1 carat diamond micropowder, can sell 0.8 dollars (about 5 yuan) in the international market, and only earn 1 yuan in the domestic market, this value contrast is too exciting. "Yucheng plus the artificial diamond industry clusters in other provinces, there are currently about 500 large and small production enterprises, the overall is large but not strong, mutual technical barriers, vicious competition. To change this status quo, only through technological innovation, standard innovation, management innovation, enhance the core competitiveness of products (industry) in the domestic and foreign markets.
Henan Province Synthetic Diamond Micropowder Quality Supervision and Inspection Center was put into trial operation in September 2014. By May 2015, the Provincial Quality Supervision Bureau expert group went to the Yucheng site for on-site assessment, and had already tested and tested more than 400 batches of product samples for the production enterprises. And within a short period of time after the authorization test, it has created a miracle of continuous improvement in detection technology and breakthrough in technological innovation. The artificial diamond "Comparative Particle Standard Material" provided by an authoritative organization used by the center has been repeatedly tested and found to have an actual transmission value error exceeding the relevant standard. After careful consultation, the professional and technical personnel of the center promptly feedback relevant test data to an authoritative organization, and questioned and consulted the value of this kind of “comparison of particulate reference materials”. An authoritative expert replied: "It is impossible. This kind of particulate reference material has been put into use for more than 20 years, and no one has ever found any questions or denials about its quality..."

Test relies on standards, standards must be scientific
In order to solve the above-mentioned "tangledness", the professional technicians of Yucheng had no choice but to report the above situation to the National Standards Substance Management Committee. After fully listening to the opinions of all parties, the National Standards Substance Management Committee held the “Particle Reference Material Coordination Meeting” on October 26, 2015 in the conference room on the 6th floor of Beijing Saifu Building, from China Metrology Academy, National Standards Substance Management Committee, The 15 experts, professors and senior engineers of the Beijing Chemical Industry and Metallurgical Research Institute of the Nuclear Industry, the Metrology Department of the General Administration of Quality Supervision, Inspection and Quarantine, and the Quality Supervision and Inspection Center of the Artificial Diamond Micropowder of Henan Province were invited to discuss the meeting. Professor Bo, a former professor-level senior engineer who has been in charge of inspection and R&D for many years in the National Abrasives Quality Research Institute, is currently the chief expert of the Henan Provincial Synthetic Diamond Micropowder Quality Supervision and Inspection Center, and made a special report at the seminar. He used the actual test data of the center to indicate that there is a quality problem in the quantity of the "particle standard substance" being used, and it is recommended that the development unit correct it. After thorough discussion, the experts unanimously adopted this proposal.
On November 12, 2015, an authoritative research institution sent the “Certificate Replacement Notice” to the Quality and Technical Supervision Bureau of Yucheng County, Henan Province, to correct the mistake of the standard substance certificate issued to Yucheng in February 2015. The original certificate was invalid. To be replaced, the superstandard magnitude error transmitted by the above “Particle Reference Material” was finally corrected.
Zhou Bo said that through the seminar, these experts and professors of authoritative research institutions in the same field in China have a comprehensive understanding of the technological innovation level of the new Henan Province artificial diamond micro-powder quality inspection center. With this special opportunity, the Center has applied to join the National Abrasives Standards Committee, and strive to obtain timely information on cutting-edge scientific and technological innovations in this field, and to obtain the right to speak in national standards innovation.

Technical innovation and cooperation to promote the standardization, scale and serialization of synthetic diamond products
Since its establishment, the center has actively established technological innovation and cooperation with 16 research institutes such as Henan University of Technology School of Materials Science and Engineering and Zhengzhou Sanmao Research Institute, which has enhanced the strength of scientific and technological innovation. The paper “Diamond Micropowder Quality Inspection” written by Liang Xiaodong, the person in charge of the center, was published in the second issue of “China Powder Industry” magazine in 2015. In this paper, three kinds of analytical methods of laser, electric resistance and particle pattern for the quality inspection of diamond micropowder are compared. The results of sensitivity test on product particle size show that the resistance method and the phase method can sensitively reflect the change of product size. The result is an effective control of product quality. The results of the laser particle size analyzer show that it is not convenient to strictly control the quality of the diamond powder. It is recommended that relevant production enterprises should optimize inspection and product analysis methods to effectively improve product quality. This achievement has been recognized in the same field and is widely applied in a wide range. The center's invention and creation "a method for sampling and quantification of diamond micropowder particle size analysis" and "a method for assessing the uncertainty of measurement results of laser particle size analyzer" were applied for on March 29, 2016. Intellectual Property Office "Patent Application Acceptance Notice".
The center has obtained the qualification of the provincial quality inspection center until August 2016, and has actually tested and tested thousands of batches of products, provided more than 200 quality inspection reports for the production enterprises free of charge, and guided the establishment of technological innovation in the synthetic diamond micropowder and product industry in Yucheng. Information network. In June 2015, under the auspices of the head of the Yucheng County Government, the center led the scientific and technical personnel of the six key enterprises to form the research and development technical group of the “Quality Standard for Synthetic Diamond Micropowder Quality Control”. Currently, this is forward-looking and advanced. New standards for the alliance are under development.
In the 30 years since the 1980s, there are more than 160 synthetic diamond micro-powder manufacturers in Yucheng County. Currently, 59 pillar-type enterprises in the industrial cluster in the Yucheng industrial cluster have formed production from raw and auxiliary materials (carbon rods). Synthetic diamond extraction processing - artificial diamond micropowder production - artificial diamond products production of a perfect industrial chain, synthetic diamond products developed into standardized, large-scale, serial production. At the end of 2015, the output of synthetic diamond in the industrial cluster area of ​​Yucheng County was 1 billion carats; the output of synthetic diamond powder was 7.8 billion carats, which has a market share of more than 70% in the domestic market; the synthetic diamond products reached 7 series and more than 140 varieties, with domestic With 30% market share, quality innovation is in the leading position in the domestic industry, and some products are sold well in Asian, European and North American international markets. At the end of 2015, Yucheng County achieved an annual output value of nearly 10 billion yuan, annual sales income of 8 billion yuan, annual profit and tax of 400 million yuan, and foreign exchange earning of 300 million US dollars.
At present, there are 10 high-tech enterprises, 5 provincial engineering technology research centers, 2 provincial engineering laboratories, 2 provincial-level enterprise technology centers, and micro-nano diamond powder academicians workstations in the industrial cluster area of ​​Yucheng County. One provincial and provincial technology incubator, 85 independent intellectual property rights, including 11 invention technology patents, and 2 products of Henan famous brand products. The technological innovation capability of the industrial zone has reached the advanced level in the province, and some projects have reached Domestic advanced level. In December 2012, the industrial cluster was approved by the Henan Provincial Government as a provincial high-tech industrial development zone. In August 2013, the Ministry of Science and Technology identified it as “the high-tech industrialization base for superhard materials and products in Shangqiu State”. On January 29, 2015, the Henan Provincial Quality Supervision Bureau agreed to complete the task of creating a “Development Zone for Famous Brands of Superhard Materials Industry in Henan Province” within 24 months on the basis of the construction of the super-hard material product industrial base in Yucheng County.
