銀管進(jìn)氧的質(zhì)譜分析
MASS SPECTRAL ANALYSIS OF OXYGEN PERMEATING THROUGH Ag TUBE
-
摘要: 本文分析了B-A規(guī)和銀管在除氣和工作過程中的放氣成份,提出了對銀管進(jìn)行N2-O2,交替高溫除氣處理。利用這一方法能有效地縮短除氣時(shí)間,提高除氣真空度和進(jìn)氧純度。文中詳細(xì)討論了影響進(jìn)氧純度的因素。

Abstract: The composition of released gasses of B-A gauge and Ag tube during degassing and operation are analyzed. The degassing processing of Ag tube at high temperature is suggested by using N2-O2 alternately. In this way, the degassing time of Ag tube is shortened effectively, the degassing vacuum is raised notably and highly pure oxygen permeating through Ag tube is obtained. The effects on the purity of oxygen are discussed in detail. -
