On September 1, 2007, the appraisal meeting for the development of the "High Temperature Combined Filter Cartridge Dedusting System" of Zhengzhou Jinhao Technology Development Co., Ltd., which was issued and funded by the Zhengzhou High-tech Industrial Development Zone, was successfully held at Yichuan Yilong International Hotel. . The meeting was hosted by the Science and Technology Department of Henan Province. Experts such as Dai Hongjun, Xia Yaofeng, Xiao Xuede, Zhao Yongde, Li Zhengxin, Lian Jinyan, Yang Zhenling and other experts carefully listened to relevant research reports, technical reports and user usage reports, and watched the demonstration of the project. Relevant information was reviewed, and questions and comments were conducted. After discussion, the following opinions were formed:
1. The project has a correct technical route, reasonable design and advanced technology. The data, technical data and drawings provided are complete and meet the requirements for appraisal.
2. Tested by Zhengzhou Environmental Monitoring Center, the dust removal efficiency of this project is high, and the dust emission concentration complies with the national “Industrial Kiln Air Pollutant Emission Standard” and “Air Pollutant Integrated Emission Standard”, and the effect is good by users. It has good economic benefits, social benefits and environmental benefits, and has broad application value.
3. The project has reasonable design, advanced technology and independent intellectual property rights. The economic, social and environmental benefits are remarkable, and the overall level has reached domestic leading and international advanced level.

Recommendation: Promote applications in multiple industries as soon as possible.

 

Alumina Ceramics

Alumina ceramics are ceramic materials based on alumina (Al2O3) for thick film integrated circuits. Alumina ceramics have good conductivity, mechanical strength and high temperature resistance. It should be noted that ultrasonic cleaning is required. Alumina ceramics is a versatile ceramic. Because of its superior performance, it has been widely used in modern society, satisfying the needs of daily use and special performance.The high-purity alumina ceramics have a Al2O3 content of 99.9% or more. Since the sintering temperature is as high as 1650-1990 ° C and the transmission wavelength is 1 to 6 μm, the molten glass is generally used to replace the platinum crucible; Sexual and alkali-resistant metal corrosion is used as a sodium lamp; it can be used as an integrated circuit substrate and high-frequency insulation material in the electronics industry.
