    摘要： Various embodiments of the present invention generally provide processes for recovering and/or using one or more constituent components of carpeting. More specifically, various embodiments provide processes for reclaiming a filler material from carpet as well as processes for using the recovered filler material in subsequent carpet manufacturing processes. The present filler recovery processes can provide recycled filler material, which can be extracted at various stages of processing, and in different purities, depending on the subsequent need or use for the recovered filler material. In some instances, the filler recovery processes described herein can be implemented as sub-processes for recycling other carpet components.

    摘要： Comminuted carpet pieces are fed to a first stirred tank together with an aqueous solution containing separating salt, to form a first suspension, which is fed to a first mechanical separating stage. A first high-solids phase, a second high-solids phase containing polymer fiber material, and a liquid phase are obtained therefrom. The second high-solids phase is mixed with a water-containing separation solution in a stirred tank, to give a second suspension, which is fed to a second mechanical separating stage. A third high-solids phase, a polymer fiber material-rich phase and a liquid phase are withdrawn therefrom. An acid which is stronger than H2CO3 is introduced into the stirred tank together with the water-containing separation solution, and the pH of the liquid in the stirred tank is adjusted to 2-6.

    摘要： The invention relates to a method for recycling electronic waste in the form of disassembled printed circuit boards from electronic devices, from which the components have not been removed, known as printed circuit boards. After removal of the batteries, mercury switches and PCB-containing capacitors, the printed circuit boards are mechanically precomminuted and the particles are cryogenically embrittled with liquid nitrogen and comminuted in a hammermill. In order to obtain a higher purity of the recovered metal concentrates and, conversely, a lower metal content of the concentrated residue materials as well as less emission during recycling and a simpler process, the cryogenically embrittled particles are selectively comminuted batchwise in a hammermill, wherein the ground material is divided into a fine fraction, emerging from a sieve at the bottom of the grinding chamber, and a coarser metallic fraction, which can be discharged batchwise and from which iron particles can subsequently be magnetically removed. The fine fraction is sorted into several narrow-band size classes with a particle size of about 1:1.6 per size class. Each individual size class of particles can be separately separated with corona-roller separators into residue material particles and metal particles. The latter can then be divided into different metal classes.

    摘要翻译： 本发明涉及一种电子废料回收电子废物的方法，电子废料的形式是电子设备，组件尚未被从中去除，被称为印刷电路板。 在取出电池，水银开关和含PCB电容器之后，印刷电路板被机械预稀释，并且用液氮将颗粒低温地脆化并在锤磨机中粉碎。 为了获得更高纯度的回收的金属浓缩物，相反地，浓缩残余物质的较低金属含量以及再循环期间的较少的排放和更简单的方法，低温裂解颗粒在锤磨机中分批选择粉碎，其中 研磨材料被分为从研磨室底部的筛子出来的细小部分和可以间歇排出的较粗的金属部分，随后可以从其中磁性去除铁颗粒。 精细分数被分类成几个窄带大小类别，每个大小类别的粒度约为1：1.6。 每个单独尺寸的颗粒级可以用电晕辊分离器分离成残留物颗粒和金属颗粒。 后者可以分为不同的金属类。
