GB-4A型Cu~(2+)分析仪用于氮肥生产中连续测定铜液中高价铜离子含量.在使用中,铜液的净化程度对仪器准确度有很大影响.因此,仪器本身配置二级过滤器,以滤去铜液中的杂质和油污.在实际应用中,过滤器一般使用三、四天,有的每天都要拆洗一次,有时还要用压缩空气,蒸汽和稀盐酸冲洗过滤器微孔,维护工作量很大,至使不少单位的仪器使用一段时间便因上述原因停下来,在应用中开表率很低.
GB-4A type Cu ~ (2 +) analyzer is used for continuous determination of copper ion content in the production of nitrogen fertilizer, in use, the degree of purification of copper liquid has a great impact on the accuracy of the instrument.Therefore, the instrument itself Secondary filter to filter copper impurities and oil.In practical applications, the filter is generally used three or four days, and some daily demolition wash, and sometimes with compressed air, steam and dilute hydrochloric acid wash Microporous filter, maintenance workload is large, so that many units of the instrument used for some time will stop because of the above reasons, in the application of a very low rate.
