Abstract: Colloidal injection moulding of ceramics (CIMC), an innovative technique combining the advantages of conventional injection moulding and colloidal forming process, is applied to prepare thin-wall rutile tube for high capacity ozone generator. The forming process is studied detailed and the processing parameter of forming, drying and sintering schedule is determined in this research. The wall thickness of the sintered tube is 1.5~2mm and its inner diameter is about 26 mm, length is about 300 mm. The electric properties of the tube are also measured under different conditions. The above-mentioned tube is applied in ozone generator and the yield of ozone is about 55mg·L-1.

Abstract: This paper is resulted from a jetting force measurement experiment. The principle and the mathematical model of a jetting force measurement system are introduced. The characteristics of the measured data and the algorithm of extracting the jetting force are examined. The experimental results verify the algorithm and the theoretical results by use of system identification techniques.
