METHOD FOR ISOLATING CELLULOSE AND OTHER ADHESIVE MATERIALS DURING THE RECYCLING OF WASTE PLASTICS, IN PARTICULAR MIXED PLASTICS |
摘要 |
The invention relates to a method for isolating cellulose and other adhesive material from waste plastics during the recycling of all types of waste plastics, in particular mixed plastics. According to said method, films and pieces consisting of thicker plastic parts of optionally pre-sorted waste plastics are mechanically pre-ground to obtain flakes or particles of a pre-determined size, any oversize material being discarded. The ground product is introduced together with water into a disc refiner, the fraction of flakes and other particles being at least 10 % of the total volume, any material adhering to the flakes is rubbed off to a considerable extent and forms a separate material and the latter is isolated from the plastic particles in an individual separation method. |
