[China Superhard Materials News] On November 15, the 2nd China (Zhengzhou) International Abrasives Grinding Exhibition was officially opened at the Zhengzhou International Convention and Exhibition Center. This year's three-wear exhibition will focus on the theme of “efficient cutting, innovative developmentâ€. The reporter of China Superhard Materials Network will take the opportunity to go deep into the first line of the exhibition to explore new technologies and new products that appear during the exhibition. It is no longer a dream to produce ceramic grinding tools in one hour?
Xi'an Yulang New Ceramic Materials Co., Ltd. is a high-tech enterprise specializing in the research, development, production and sales of new ceramic materials in the state-level Shaanxi Aerospace Economic and Technological Development Zone. We adhere to the enterprise development strategy of “people-oriented, continuous innovation, and foster core competitivenessâ€. We focus on developing environmentally friendly new materials, build a new ceramic material research and development platform, and give full play to the performance advantages of this material to help upgrade the enterprise. For the direction, to solve the "difficulties" in production as the entry point, share the innovation dividend, and achieve multi-industry docking.
According to the material composition to determine the structure, structure determines the performance, the performance of the value of the law, we take the inorganic polymer theory as a guide, draw on the material composite advantages, take a different approach, start from changing the material system, through long-term exploration experiments, research and development to produce original The thermosetting ceramic bond has a curing temperature of only about 200 °C, which completely changes the backward technology of high-temperature physical sintering of traditional ceramics, and simplifies the complicated problems. Some impossible things have become a reality. It is a good solution to the "difficult problem" of super-hard abrasives without ideal ceramic bond.
Specifically, the principle and process of using resin binder, using the characteristics of low curing temperature of thermosetting ceramic binder, drawing on the advantages of powder metallurgy production, taking the road of composite materials, and making the advantages of branches, ceramics and metal binders organic. Combine and learn from each other. The formation of advantages and organic complement each other, play its synergistic effect, so as to better meet the production of superhard abrasives. The "new, strange, special" property of the binder makes it possible to produce ceramic abrasives in one hour.
The thermosetting ceramic bond has the following characteristics:
1. The thermosetting ceramic bond is a low-temperature bond in the true sense. It is generally hot-pressed at about 200 °C. It does not require secondary curing. It can avoid oxidation of diamond and CBN, and can save energy and reduce pollution. ,Increase productivity.
2. There is a phenomenon of polycondensation during the curing process, which can improve the holding power of diamond and CBN abrasives.
3. The binder is an inorganic material with good high temperature resistance and no carbonization.
4. The carcass is a ceramic base. The ceramic has good toughness and can overcome the shortcomings of the traditional ceramic bond.
5, take the road of material compounding, play the synergy effect of materials. The thermosetting ceramic powder and the metal powder are hot-pressed, so that the strength and toughness of the ceramic material are improved, so that the hardness and wear resistance of the metal material are improved. Therefore, the carcass has the advantages of high strength, good toughness, high hardness, and resistance to friction. The proportions of the components can be adjusted as needed to suit different grinding objects.
6. The binder is chemically synthesized and reaches atomic level recombination, and more than 50% reaches nanometer level, which can solve the technical problem of producing micro-graded diamond and CBN grinding wheel.
7. Seamlessly connect with the traditional resin grinding wheel production process without modifying the production equipment.
8. Pure inorganic synthesis, free of harmful components such as benzene and formaldehyde, will not harm the health of producers and users.
9. Make the production process more efficient, energy-saving and clean. Provide strong technical support for the abrasive industry to eliminate backward production methods and achieve sustainable development.
