| 摘要 |
A method for producing coloured, homogeneous surface-structures from thermoplastic synthetic materials, wherein an initial mixture, based upon thermoplastic synthetic materials, is processed, by thermal pretreatment above the softening temperature, into an agglomerate or granular material and, after any necessary intermediate steps, is mechanically comminuted into a granular mixture having any desired grain-size distribution. The granular mixture of freely flowing particles is shaken continuously onto a conveyor-belt in a uniform layer and is sintered, under the action of heat, until the thermoplastic material plasticizes, to form a coherent surface-structure, being then compressed under the action of pressure and heat. |
