| 摘 要： | 以铝合金隔热型材用聚酰胺隔热条为研究对象，比较了GB／T1033．1-2008规定的非泡沫塑料密度测定中的浸渍法与GB／T1423-1996规定的贵金属密度测试法所测得的结果，通过理论计算说明两者的偏差不是误差，而是由于公式应用不当引起的。GB／T1033．1-2008中的浸渍法只在极限情形，即金属丝的影响可忽略时才成立，一般试验条件并不满足此极限要求，而GB／T1423-1996中的贵金属密度测定法更具有合理性和普遍性。

| Abstract: | The density of thermal barrier strips of polyamide used for thermal barrier profiles of aluminum alloy determined by immersion method in GB/T 1033.1-2008 was compared with the results given by method of determining the density for precious metals in GB/T 1423-1996.Theoretical calculation showed that the deviation of density caused not by experimental error,but by improper formula application.Immersion method in GB/T 1033.1-2008 proofed correct only under the limitation in which the effect of wire could be ignored.As normal test conditions fail to satisfy such limitation requirement,method in GB/T 1423-1996 is recommended in consideration of its rationalities and universality. |
