Discussion on dry basis and wet basis representation in KCl product analysis and calculation

浅谈氯化钾产品分析结果计算中干基表示法和湿基表示法,介绍了氯化钾产品先以湿基计,再换算成干基计的计算方法,通过国内外氯化钾产品含量干湿基和优缺点对比,阐述了产品水分较大时,氧化钾含量以有效成分为主表示时,应采用干基计更合理,更具有可比性,水分较小几乎不影响检测结果时,主含量以湿基计较为合适。

Dry basis and wet basis representation in KCl product analysis and calculation is discussed in this paper.Also,the conversion of wet basis representation to dry basis representation with KCl product is introduced.These two representation ways and their advantages and disadvantages are compared to illustrate a more suitable representation way through the product of KCl at home and aboard.The results show that:when the water content of KCl is higher and the content of KCl is expressed with effective constituents,the dry basis representation is more suitable and comparable;when the water content is less and nearly doesn’t affect the measured effects,the main content expressed with wet basis is more suitable.
