Development and application of Mooney viscosity series reference materials
Mooney viscosity is a key index for the quality control of rubber industry,which plays a vital role in the quality of rubber industry.In order to meet the requirements of technological progress in the rubber industry,the selected synthetic rubber industrial samples were tested for homogeneity and stability according to the relevant regulations for the development of reference materials,and the values were determined jointly by a number of laboratories,and through a series of work such as abnormal data judgment,data normal distribution test,Equal Precision Test and uncertainty evaluation,a series of certified reference materials with different synthetic rubber and different Mooney viscosities were developed,the standard values of Mooney viscosity of the series of reference materials were 45.6±0.5,49.1.0.8,76.6±0.8,42.4±0.8,66.3±1.1,81.9.1.4,76.2±1.1,86.6±1.0.52.2±0.7,33.5±0.8,51.2±1.0,respectively,the development of the series of reference materials for the rubber industry production control,product inspection,product trade,quality arbitration to provide technical support in the rubber industry has been widely used.
