Deoxidizing tube HTG is used for hydrogen or hydrogen gas catalytic deoxidization. It is mainly used for chromatographic spectra, energy, such as carrier gas purification, used in the chemical, electronic, metallurgy, medicine and food, aerospace and other research field of anaerobic operation and ultra pure gas preparation.
Hydrogen gas oxygen amount: O2≤3%. This paper describes and analyses principles of the main parts of CRT monitor, and arranges relative experiments for the students to get a working knowledge of the CRT monitor maintenance including experiment on the basic 3 colors with mixed time, experiment on characters of negative electrode of picture tube and deflection coil, experiment on vertical scanning output circuit, and experiment on horizontal scanning output electricity, all of which are characterized by a close combination with corresponding concept, simple procedures and apparatus(multimeter and computer only) .
The activation and regeneration: No need
For building a long-span concrete-filled steel-tube (CFST) curve bridge with an integrated installation tower,one of the key technologies is to control the arch rib alignment of the bridge.Based on the theoretical analysis and the measuring results,the designed arch rib alignment of a existence expanded bridge over give the sack be guaranteed quality by adjusting the length of the cables on-line.The engineering application shows,by using the on-line correcting cablegram technology,that it is economical and in safety for building a long-span CFST arch bridge.
Residual oxygen [hydrogen] (PPM)after purification:O2≤0.1ppm
