Dear Academician Li Peigen, Academician of the China Society of Mechanical Engineering, Academician Tan Jianrong, deputy director of the Henan Association of Science and Technology, Shangqiu City, distinguished guests, delegates: good morning everyone! First of all, please allow me to represent the organizers and organizers of this forum and express my warm welcome to the industry colleagues from home and abroad! Welcome everyone to Zhengzhou, Henan! Here is the birthplace of China's synthetic diamonds, known as the world's synthetic diamond capital by foreign counterparts; here is the only national Torch Plan superhard material industry base approved by the Ministry of Science and Technology, and the only superhard material and products approved by the National Development and Reform Commission. High-tech industrial chain construction base. Current situation Zhengzhou is at the intersection of the east, the west, the south and the north in the geographical coordinates. This time, in the time coordinate, this seminar is also at the intersection of the new and old times of industry development. For the super-hard materials industry, the past more than half a century is the era of tools. It is an era in which super-hard tools are gradually developed from scratch. The main tools are grinding, drilling, sawing and cutting. High mechanical properties; From now on, the 21st century is a functional era, which will be developed in the direction of functional applications. It is necessary to exploit the special properties of diamond, such as sound, light, electricity and heat, to open up new areas of its functional applications. The age of functionality does not mean that tools are outdated. In the age of functionality, new superhard tools will continue to evolve and will continue to revolutionize efficiency and precision. For example, Abrasive tools: This is the earliest development of superhard material tools, and is still in the early stage of development. The world-recognized abrasive abrasive industry development trend AB→CD progress, that is, diamond, CBN abrasive tools to replace SiC, corundum abrasives, so far the replacement rate is less than 30%. For example, the tool: it is still in the ascendant. Diamond, CBN tools instead of hard alloys, high-speed steel tools, is also a general trend, but the current replacement rate is less than 10%. In the "13th Five-Year Plan" "National New Materials Industry Development Guide" document, as "CNC machine tool materials", both diamond and CBN are listed as key development products. For example, wire saws, which began to enter the photovoltaic and IT industries from alternative silicon carbide mortar saws, were introduced abroad in the 1990s, and domestic production has only been in the past ten years. In the first few years, only a few companies such as Muller, Huajing, and Sanchao produced very few. Diamond wire saws have achieved outstanding performance in many years due to their application in the photovoltaic and IT industries to improve efficiency, accuracy, and material yield while reducing costs and eliminating pollution. A large number of diamond wire saw enterprises have appeared in various parts of the country. Among them, some enterprises have already scaled up production and even came to the fore. Some enterprises have just been put into operation, some factories are under construction, and some are ready to build factories, which are being planned and designed. The above-mentioned tools such as abrasive tools, tools and wire saws, if the grinding tools are in the early stage of development, equivalent to the sun at 10 o'clock in the morning, the tool can be said to be eight or nine o'clock, and the wire saw is about seven o'clock in the morning. The functional application of superhard materials in the fields of light, electricity, sound and heat is still only in the pre-dawn stage. It is the beginning of the show, and the small lotus is sharp and sharp, and the industrialization curtain has not been fully opened. The super-hard materials and products industry is undoubtedly a sunrise industry, and its development prospects are limitless. Issues that need attention The diamond wire saw is currently a hot spot, and it seems that the development situation is very good. In a good situation, if you look calmly, you will find that there are some issues that need attention. ♦ From the diamond wire saw industry development model Need to pay attention to the same technology, simple replication of the same model, to avoid duplication of construction; need to pay attention to the same product homogenization competition problem, to prevent falling into a vicious circle of price wars; need to pay attention to the development of different varieties, different uses of wire saws, to promote serialization, special Differentiation and development. ♦ From the core technology of diamond wire saws Although wire saws have entered the stage of industrialization, the technology is not very mature, and there are still many problems to be solved. E.g: High-speed plating solution and brush plating process applied to wire saws; plating wire saw and Resin wire saw abrasive combination is not strong; need to find another way to find other new wire saw manufacturing methods; diamond wire saw processing silicon material, surface The problem of streaking; the problem of popularizing applications in processing polysilicon, and so on. These are major technical issues that hinder the development of the industry and need to be further studied. Around the theme of this conference, we have invited experts from various fields to make a series of special reports covering the entire industrial chain of diamond wire saws in the middle and lower reaches, including raw and auxiliary materials, production processes, product standards and application technologies. Etc. The content system is comprehensive and colorful. We look forward to the fruitful results of this forum under the joint efforts of all of you. Conclusion In summary, under the new situation of the booming and rapid expansion of the current wire saw industry, we held a seminar in Zhengzhou to discuss issues of concern to us, clarify the direction of advancement, and guide our wire saw industry. It is necessary to develop rapidly and to develop healthily; it is necessary to achieve the world's first industrial scale and the world's first quality level. This is our dream, our goal. The purpose and significance of this meeting is also here! Finally, I would like to thank all the sponsors for their unity and cooperation, and thank the sponsors for their support. I wish all friends and all the guests a good job during the Zheng period, happy and healthy! thank you all! Cocamide DEA, or cocamide diethanolamine, is a diethanolamide made by reacting the mixture of fatty acids from coconut oils with diethanolamine. CDEA,Coconut Diethanolamide CDEA,CDEA For Washing Hand,Cocamide DEA 6501 Yucheng Jinhe Industrial Co.,Ltd , https://www.jinhetec.com
Characteristics:
1.Excellent decontamination, wetting, dispersion, anti-hard water, and antistatic performances.
2.Perfect thickening, foaming, foam-stabilizing and derusting abilities.
3.Compounded with other anionic surfactants, such as LABSA, the foaming ability will be obviously improved, and foam is more affluent, stable, and long-standing. The washing effect is also enhanced.
Application:
1.Added in shampoo and hand washing, it can not only stabilize foam and thicken the liquid,
but also will reduce the irritation to the skin.
2.For it can soften fiber textile, it is especially suitable for washing animal fiber, such as hair and thread, etc.
3.Its applications are in liquid Detergent, shampoo, dishware detergent, liquid soap, fiber
modifier, wool cleanser and metal rinse, etc.
4.Also used in electric plating, shoe polish and printing ink, etc.
