Recycling plastic waste |
摘要 |
A method and apparatus for recycling plastic waste to produce a wood substitute material for use in manufacture of garden products. A mixture of one or more types of plastic materials is extruded in a partially plasticised condition so as to allow gases formed by the extrusion process to escape from the surface of the extrusion to create a simulated wood. Holes (9) formed in the surface of the extruded plastic material by escaping gases are elongated by passage of the extrusion through a finishing die (7) downstream of the extruder (5) to form a rough textured surface similar to sawn wood and the plastic material is set to retain the shape and configuration of the textured surface by cooling in a water bath (8) downstream of the finishing die (7). |
