丁二烯橡胶(BR)9000门尼黏度标准物质的研制

Preparation of mooney viscosity of butadiene rubber(BR) 9000

对经过筛选、通过均匀性、稳定性检验后符合标准物质定值的丁二烯橡胶样品,采用多家实验室联合定值。并对各家实验室定值的结果按照标准物质定值数据处理程序,进行了异常数据判断、数据正态分布检验、等精度检验、不确定度评估。丁二烯橡胶门尼黏度标准物质定值各实验室的数据在a=0.05的显著水平时,数据无可疑值、处于正态分布、等精度,定值标准物质的标称值为ML(1+4)100℃(45.6±0.5)。该标准物质的研制成功,普遍用于校准门尼黏度计,将会在合成橡胶行业得到广泛的应用,同时为合成橡胶行业生产控制、产品检验、产品贸易、质量仲裁提供技术支撑。

The value of butadiene rubber was defined according with standard material value after preparated,passed by uniformity and stability measure by laboratories.The dispose of proceed of standard material value was used to judge of unusual numbers,inspect of distributed numbers,testy of equal precision,appraised of uncertainty.When remarkable level a=0.05 of standard material of mooney viscosity after tested by laboratory,the number was certainty,normal distribution and equal precision,the value of standard was（45.6±0.5）ML（1＋4）100 ℃.Successful preparation of standard material should be supported to control of produce,trade of goods and arbitration of quality.
