The appraisal committee chaired by Professor Cai Zuquan heard the development report, performance test report, and new report of the translucent alumina tube. The sample was viewed. After discussion, the following opinions were formed: The report was full and reliable, and the production technology was analyzed reasonably; The screw extrusion advanced technology prepares the raw material tube, the extrusion pressure is low, the surface is smooth, and the quality is ensured; the roundness and the straightness are maintained; the translation device is designed and manufactured by itself, the yield is improved, and the continuous extrusion molding and Large-scale production laid the necessary foundation; the key technology of screen printing was solved; jumpers were successfully printed on the raw material tube; dry plugs were prepared and co-fired with the green tube. The prepared alumina tube meets GE's technical standards in terms of roundness, straightness, transmittance, microstructure and life. The experts at the meeting unanimously agreed that the techniques of extrusion molding and co-sintering for large-scale production of integrated translucent alumina tubes are basically mature. This achievement is at the international advanced level and is the leading domestic one.
Developed an integrated translucent alumina tube for high pressure sodium lamps
Recently, the Shanghai Branch of the Chinese Academy of Sciences convened a scientific and technological achievement appraisal meeting on the "Integrated translucent alumina tubes for high-pressure sodium lamps" undertaken by Wang Shiwei's researcher.
