含示踪剂的PE100级管材专用树脂TUB121N3000B的开发
|
摘要
针对管材市场中出现的"白"加"黑"路线及掺混回收料制备混配料的现象,在实验室中以含有示踪剂的PE100级管材专用TUB121N3000B混配料为目标,使用X射线荧光光谱分析仪和手持式检测器对示踪剂可检性、稳定性及用量等进行了研究,并在此基础上,实现了TUB121N3000B的工业化生产。结果表明:使用示踪剂对掺混料可起到较好的辨别作用;X射线荧光光谱分析仪与手持式检测器两种仪器对示踪剂含量的实际测试值与理论值基本一致,X射线荧光光谱分析仪的检测偏差在1.0~2.0μg/g,手持式检测器的为4.0~8.0μg/g;示踪剂在混配料反复挤出过程中不会有明显的损失,表现出较好的稳定性;X射线荧光光谱分析仪可用于定量分析混配料中掺混料的含量,而手持式检测器仅可以定性分析混配料中的掺混料。
This paper focuses on the preparation of mix ingredients through White &Black routine or by mixing recycled materials during pipe production. The availability,stability,adding amount of tracer in polyethylene(PE)100 tube specialty TUB121N3000B were investigated in laboratory by use of X-ray fluorescence spectrometer(XRF) and handheld detector,based on which the industrial production of anti-fake TUB121N3000B was realized. The test results show that the tracer can be used to distinguish the mix materials. The results obtained from XRF and handheld detector are identical to theoretical values. The deviation of XRF ranges from 1.0 to 2.0 μg/g and that of handheld detector of 4.0-8.0 μg/g. The tracer suffers less loss during repeated extrusion,showing its stability. XRF can be used for the quantification of the mix ingredients in mix material and the handheld detector for qualification only.
