Green manufacturing brings great opportunities for the super-hard materials industry - China Diamond Industry New Technology Forum held successfully
On the morning of August 16th to 17th, the China Diamond Industry New Technology High-Level Forum was held in Qinhuang Holiday Hotel, Qinhuangdao City. The unique advantages and broad application prospects of super-hard materials and products in low-carbon economy and green manufacturing became the attention of participating experts. Focus. Since the carbon of the diamond-making raw material is a recyclable resource compared to ordinary abrasives, the super-hard material industry has the characteristics of renewable economy, and the energy consumption for manufacturing super-hard materials and products is also low, and more importantly: Superhard material tools provide important technical support for promoting low-carbon and energy-saving emission reduction in all areas of modern industry, which will lead to the explosive application of super-hard materials and products in China in the future to promote a low-carbon economy. Original Soundtrack : During the one-and-a-half-day meeting, the experts discussed and demonstrated the development and trend of superhard materials, especially diamonds and products, from raw material selection to process setting, from enterprise management to superhard product application. Green manufacturing and low carbon development have become industry consensus. Background analysis : In fact, superhard materials and products have always played an important role in industrial processing applications. With the introduction of the national 12th Five-Year Economic Transformation and structural adjustment policies, superhard materials and products are due to their excellent processing efficiency. With the unique use of functions, the advantages in the industrial field of low-carbon economy are becoming more and more obvious. The essence of green manufacturing is the problem of efficient use of energy and the development of new energy. Superhard materials and products are industrial consumables in the field of product processing, and their performance largely affects the production of green GDP. Due to the high processing efficiency, high processing quality and low pollution energy consumption of super-hard materials and products, it will play a major role in reducing industrial energy consumption. For example, the PDC bit will open the way for green energy drilling. Due to the gradual depletion of coal petroleum energy, natural gas will become the main force in the future energy field, and natural gas combustion only produces carbon dioxide and water, and less pollution is the direction of energy development. . However, the exploration and development of natural gas has large investment, long construction period and high technical difficulty. The wear resistance of synthetic diamond is far more traditional. Applying it to petroleum probes will bring a qualitative leap to the entire drilling technology, which is in line with green manufacturing. the concept of. At the same time, ultra-hard tools, high-speed CBN grinding wheels, diamond wire and Other super-hard products also have unique energy-saving advantages in green manufacturing, especially the application of diamond wire in photovoltaic new energy is also well known to the industry. The market for super-hard materials and green products also has great potential. According to reports, the current annual output of PCD and PCBN cutting tools in China is 400,000, and the sales volume is less than 20,000 yuan. The investigation by authoritative departments shows that the total market sales of the two tools will be More than $1.5 billion. In addition, due to the obvious advantages of cemented carbide and ordinary abrasive tools, superhard material products have explosive applications in electronic information, aerospace, infrastructure, mechanical engineering and even nuclear energy, and future marine combustible ice development. breakthrough. The application of diamond function is also a highlight of the future development of the super-hard materials industry. Although the functional application of diamond is still in its infancy, the preliminary practice of photovoltaic optoelectronic applications and nano-applications has begun to appear, and the prospects are expected. Policy support : In recent years, the super-hard materials industry has received strong support from the policy. The 12th Five-Year Plan for China's machine tool tools is focused on the development of products and technologies. The super-hard materials and products are encouraged to develop abrasive deep-processing products for CNC. High-end abrasive tools for machine tools (high-efficiency, high-speed, heavy-duty, precision and ultra-precision abrasives, new low-temperature bonding agents, etc.) and coated abrasives (synthetic diamond, cubic boron nitride coated abrasives and all-polyester fabrics) Heavy-duty abrasive belts, special coated abrasive belts, etc.). Coarse particles (more than two millimeters and gem grade) and fine particles (nanoscale) superhard materials and CVD diamond, superhard composite materials; all kinds of superhard materials (high-speed high-efficiency high-precision super-hard material grinding wheel for CNC machine tools, forming and finishing Abrasives such as rollers; special tools for precision high performance boring, milling, reaming; series tools for wafer processing in IC and IT industries; special saw blades for high-grade diamonds; tools for nano-scale diamond products and diamond geological drilling tools. It is proposed that the abrasives industry should promote innovative processes, energy conservation, emission reduction, waste recycling and reuse, and shift to a low-carbon environmentally friendly production mode. Vigorously develop super-hard materials and products with obvious low-carbon environmental protection characteristics, and accelerate its popularization and application. In the 12th Five-Year Plan for new materials to be released in September, super-hard materials and products will also be included as strategic emerging industries, supported by the strategic support of national policies. Typical examples : With the continuous expansion of new applications of super-hard materials Superhard materials continue to make breakthroughs in the technology of supporting new energy and gradually become industrialized. In the first half of this year, Jiangxi Jinkui Energy Technology Co., Ltd. has successfully achieved the production of solar monocrystalline silicon wafers by the world's most advanced diamond wire cutting technology. It is three times faster than traditional mortar cutting technology, and consumes two-thirds of the water and electricity consumed. Silicon powder can be recycled. It is energy-saving and environmentally friendly, and has the advantages of high efficiency and long life. It is of great significance for upgrading the domestic industry. The Henan Diamond Plan also plans to start the production of the diamond line project within one and a half years, and the production capacity will reach 0.33. Mm photovoltaic diamond wire is 14.4 million km / year, used to cut silicon ingots; 0.12mm diamond wire 132,000 km / year. Editor's quick comment : Although super hard materials are facing a great opportunity to accelerate development, but super hard for green manufacturing Materials and products are usually high-end products with high manufacturing strength and high technical threshold. Currently, they are mainly controlled by foreign manufacturers. China has only a small share, which requires us to increase management and scientific research. At the same time, super-hard materials enterprises It should also consider how to achieve its own green manufacturing and energy conservation and emission reduction, such as research on waste superhard materials and product recycling.
