Abstract

A rectangular polymer profile made of glass fiber-reinforced thermoplastic sheathing material and a polyethylene terephthalate foam core were to be separated for recycling. For this purpose, a mechanical recycling process utilizing a cutting mill and the high-voltage fragmentation (HVF) process were used and their achievements in composite separation were compared. For both separation methods, parameter variations resulted in a total of two test series each consisting of drying, screening, optional density separation, ashing, weighing, microscopic analyses, and glass fiber length measurements. Using HVF, a better separation of the core and sheath materials was achieved and longer glass fibers could be recovered.

利用高压碎片回收热塑性玻璃纤维增强复合材料
由玻璃纤维增强热塑性塑料护套材料和聚对苯二甲酸乙二醇酯泡沫塑料芯材制成的矩形聚合物型材需要分离回收。为此,我们采用了利用切割机的机械回收工艺和高压破碎(HVF)工艺,并比较了这两种工艺在复合材料分离方面的成果。对于这两种分离方法,参数的变化导致了总共两个系列的测试,每个系列包括干燥、筛选、可选密度分离、灰化、称重、显微分析和玻璃纤维长度测量。使用 HVF 可以更好地分离芯材和鞘材,并回收更长的玻璃纤维。
