摘要
在采用稀释作图外推法测定尼龙 - 11特性粘度的大量实验基础上 ,研究确定了用乌氏粘度计单点法测定尼龙 - 11特性粘度经验公式中的经验常数 ,通过与稀释法的比较 ,检验其准确度和精确度。结果表明 ,误差小于± 0 5%的单点法可用于测定尼龙
On basis of measuring the characteristic viscosity of Nylon-11 by means of the viscosity method,the experiental constant has been found which was in the experimental formula with aid of the U viscometer and single dot method,meanwhile its accurancy and precision were inspected by comparision with the vicosity method. The results show that it is feasible for the characteristic viscosity of Nylon-11 to be tested using single dot method whose error is within±0.5%.
