化肥厂生产的二氧化碳与纯氮气混合,并加入微量乙醇而灌制成的船用救生筏专用钢瓶可作为海洋救生艇中自动充气源设备。救生筏专用钢瓶中加入微量乙醇可提高气瓶中二氧化碳的汽化温度,使其在瞬间的充气中保持气流的稳定,防止因二氧化碳的冷凝阻塞气流。工艺生产中,救生阀专用钢瓶混装的二氧化碳、氮气及微量乙醇的含量比例必须严控制。为了准确测定各组分及痕量杂质的含量,我们采用改装的气相色谱仪
Carbon dioxide produced by the fertilizer plant mixed with pure nitrogen and added with trace amount of ethanol can be used as automatic inflatable source equipment for marine lifeboats. Adding a small amount of ethanol to the life raft special cylinder can increase the vaporization temperature of the carbon dioxide in the cylinder so that it maintains the stability of the air flow in an instant inflation and prevents the airflow from being blocked by the condensation of carbon dioxide. Process production, life-saving valve for cylinder mixed carbon dioxide, nitrogen and trace ethanol content ratio must be strictly controlled. In order to accurately determine the content of each component and trace impurities, we use a modified gas chromatograph
