A method of heating plasticity plastic-plate and heating plasticity plastic-plate

摘要

PURPOSE: A production method of a thermoplastic synthetic resin plate and the thermoplastic synthetic resin plate are provided to improve the wear resistance and the shock resistance without damaging a particular material and to improve the hygroscopic property and the sound absorbing property by sticking natural color particles on the synthetic resin plate. CONSTITUTION: A thermoplastic synthetic resin plate is formed by rolling a plastic material from an extruder through primary and secondary forming rollers(3,4). Natural color particles are spread on the synthetic resin plate. The natural color particles are stuck to the upper face of the synthetic resin plate by sequentially passing the synthetic resin plate through cooling rollers. Thereby, the wear resistance, the hygroscopic property, the sound absorbing property and the shock resistance are improved.
