提高棉包回潮率测试代表性方法探究

Research on representative methods for improving the rate of moisture regain of cotton bales

现行回潮率测试结果代表性问题一定程度上影响了棉花公定重量的稳定性,为解决上述问题,本研究将提高回潮率测试仪器测试数据的代表性作为拟解决的关键技术问题。利用比较研究的方法,采用多种测试和计算方法,测定棉包在不同时间、地点、环境下的棉花回潮率以及基于该回潮率计算的公定重量数值,比较不同测试和计算方法下棉花公定重量数据的变化情况,利用棉花公定重量恒重的基础理论,探索提高棉包回潮率测试代表性方法。

The representativeness of the current moisture regain test results has to some extent affected the stability of cotton's conditioned weight.To address these issues,this study aims to improve the representativeness of the moisture regain test instrument test data as a key technical issue to be addressed.Using comparative research methods and various testing and calculation methods,the moisture regain of cotton bales at different times,locations,and environments is measured,as well as the numerical values of the declared weight calculated based on this moisture regain.The changes in the declared weight data of cotton under different testing and calculation methods are compared.Using the basic theory of constant weight of cotton,the representativeness of testing the moisture regain of cotton bales is explored.
