用于过滤基材材料的方法
摘要：
本发明涉及一种用于过滤聚碳酸酯的方法，其特征在于，通过至少一种厚度为5mm～1mm的、由2层或多层组成的、金属非织造物过滤平均分子量（重均）为14,000～30,000g/mol的聚碳酸酯熔体，其中至少一层厚度为0.05～0.2mm，孔径为1～10μm。
摘要（英）：

The invention relates to a method for filtering polycarbonate, characterized in that the polycarbonate melt having an average molecular weight (weight-average) of 14.000 to 30.000 g/mol is filtered through at least one metal nonwoven having a thickness ranging from 5 mm to 1 mm and comprising two or more layers, at least one layer having a thickness ranging from 0,05 to 0,2 mm and a pore size from 1 to 10 [mu]m.
