介绍了纯锆在电化法制过氧化氢的生产中用作一次水解管和浓缩管的试验结果。纯锆作为一次水解管,其年腐蚀率低于0.25mm/年,1.5mm壁厚的锆水解管可以连续使用三年以上,有良好的经济效果。氩弧焊接不影响其腐蚀性能。纯锆浓缩管的年腐蚀率几乎等于零,可以长久使用。 The experimental results of pure zirconium used as primary hydrolysis tube and concentration tube in the production of hydrogen peroxide by electrochemical method are introduced. Pure zirconium as a hydrolysis tube, the annual corrosion rate of less than 0.25mm / year, 1.5mm wall thickness of the zirconium hydrolysis tube can be used continuously for more than three years, with good economic results. TIG welding does not affect its corrosion performance. Pure zirconium enrichment tube annual corrosion rate is almost equal to zero, can be used for a long time.
