Title:
再生プラスチック材料の製造方法
Document Type and Number:
Japanese Patent JP4365984
Kind Code:
B2
Abstract:
When thermoplastic is recycled by a general recycling process alone, only a low-quality recycled plastic material having physical property values lower than a virgin material can be obtained. A recycled plastic material of this invention is made from laser-engraved thermoplastic, metal-containing thermoplastic, thermoplastic used in an inkjet apparatus, or thermoplastic to which an ink or its composition have stuck. This recycled plastic material is manufactured by pulverizing any of these thermoplastics, cleaning the pulverized thermoplastic, removing a cleaning solution from the cleaned thermoplastic to dry it, and removing from the dried thermoplastic solid matter other than the thermoplastic.
