摘　　要：为了研究不同批次PVC管道抗冲助剂的差异性,本文通过X射线荧光光谱仪(XRF)、傅里变换叶红外光谱(FT-IR)、马弗炉以及转矩流变仪对四个不同批次PVC抗冲助剂进行表征。从XRF、FT-IR以及灰分测试的数据可以看出,样品1的无机盐(包括硬脂酸钙)含量与其他三个样品存在明显差异。从转矩流变试验的结果显示,样品1在塑化时间以及塑化速度方面与其他三个样品存在明显差异。In order to study the differences of impact additives for different batches of PVC pipes,four different batches of PVC impact additives were characterized by X-ray fluorescence spectrometer(XRF),Fourier transform infrared spectroscopy(FT-IR),muffle furnace and torque rheometer.From the data of XRF,FT-IR and ash test,it was observed that the content of inorganic salts(including calcium stearate)in sample 1 was significantly different from the other three samples.The results of torque rheological test show that the sample 1 was significantly different from the other three samples in terms of plasticizing time and plasticizing speed.
