Abstract
In the domestic and international washing machine industry,the existing testing methods for rinsing performance have a lot of problems,such as complex operation,additional reagents,inability for directly measuring,and high-intensity testing works,etc.Based on this,A test method for rinsing performance of washing machine based on conductivity was proposed.The linear correlation between the concentration of standard solid detergent and conductivity was analyzed,and the calculation formula for rinsing rate and detergent residue was established accordingly.The accuracy,distinguishability,repeatability,reproducibility and consistency of the method were evaluated comprehensively.Results showed that there is a good linear relationship between the conductivity and the concentration of standard detergent.The conductivity method has high accuracy,good distinguishability,repeatability,reproducibility and consistency.Moreover,it can used for directly and accurately evaluating without additional reagents,with simple operation,and high reliability.Results showed that the new rinsing testing method has a good application prospect.关键词
