XH-431 过滤性测试机      XH-431 Filter testing machine

简介：本机适用于PP、PE、PET塑胶、以挤出压滤方式测试颜料、添加剂及色母粒等聚合物的分散性能。

Introduction: This machine is suitable for PP, PE plastic, through extrusion and pressure filtration to test the dispersion properties of pigments, additives, masterbatches and other polymer. 

工作原理：测试原料先经单螺杆挤出机熔融、均化、后经熔体泵输送至装有滤网的模头，仪器实时测量，记录滤网前的熔体压力变化曲线，并自动分析和计算压滤值，实现对色母料或其它填充物料分散性能的表征，测试结果自动输出，界面直观，资料准确。

Working principle: The test material is melted and homogenized firstly by a single screw extruder, then conveyed to the die with a filter by the melt pump. The instrument measures in real time, records the melt pressure change curve before the filter, automatically analyzes and calculate the pressure filter value to achieve the characterization of the masterbatch or other filler material dispersion perbance, test results automatically output, intuitive interface, accurate data.
