利用X射线衍射仪测量β-PPR管件中β晶含量

Determination of the β Crystal Content in β-polypropylene Random Copolymer Fitting by X-ray Diffraction Analysis

本文运用X射线衍射仪测试β晶型无规共聚聚丙烯(β-PPR)管件中β晶含量。讨论了扫描速度、测试功率和接收狭缝等测试条件对结果的影响。结果表明,较慢的扫描速度、较高的测试功率、适当的接收狭缝等条件下测试结果相对可靠。

The β crystal content of polypropylene random copolymer fitting was measured by X-ray diffractometer.The effect of scanning speed,test power and receiving slit on the results are discussed.It was shown that the test results are relatively reliable under the conditions of slower scanning speed,higher test power and appropriate receiving slit.
