Estimating the term…
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.
A recycled plastic material made from laser-engraved thermoplastic.
A recycled plastic material manufactured by pulverizing laser-engraved thermoplastic, cleaning the pulverized thermoplastic, removing a cleaning solution from the cleaned thermoplastic to dry said thermoplastic, and removing from the dried thermoplastic solid matter other than said thermoplastic.
A recycled plastic material made from thermoplastic containing a metal.
A recycled plastic material manufactured by pulverizing thermoplastic containing a metal, cleaning the pulverized thermoplastic, removing a cleaning solution from the cleaned thermoplastic to dry said thermoplastic, and removing from the dried thermoplastic solid matter other than said thermoplastic.
A recycled plastic material made from thermoplastic used in an inkjet apparatus.
A recycled plastic material manufactured by pulverizing thermoplastic used in an inkjet apparatus, cleaning the pulverized thermoplastic, removing a cleaning solution from the cleaned thermoplastic to dry said thermoplastic, and removing from the dried thermoplastic solid matter other than said thermoplastic.
A recycled plastic material made from thermoplastic to which ink and components thereof have stuck.
A recycled plastic material manufactured by pulverizing thermoplastic to which ink and components thereof have stuck, cleaning the pulverized thermoplastic, removing a cleaning solution from the cleaned thermoplastic to dry said thermoplastic, and removing from the dried thermoplastic solid matter other than said thermoplastic.
A method of manufacturing a plastic part, comprising the steps of:
A method of manufacturing a plastic part, comprising the steps of:
A recycled plastic material manufactured by recycling a part molded from a thermoplastic material, characterized in that an impact strength of said recycled plastic material is not less than 80% of a virgin plastic material, and a melt flow rate (MFR) of said recycled plastic material, which indicates the flowability of a plastic material is 90 to 120% of the virgin plastic material.
A method of manufacturing a recycled plastic material, characterized in that in order to recycle a part molded from a thermoplastic material, plastic is repelletized through steps of pulverization, cleaning, drying, and foreign matter removal of said molded part, and an impact strength and a melt flow rate (MFR) of said plastic pellets are adjusted within the ranges of predetermined values.
A method of reusing a plastic material, characterized in that a part is molded from a plastic material, said molded part is used as a part after a laser engraving display is formed on said molded part, a recycled plastic material is formed through steps of pulverization, cleaning, drying, and foreign matter removal of said part, and an impact strength of said recycled plastic material falls within a predetermined range of an impact strength of a virgin plastic material.
A method of reusing a plastic material, characterized in that a plastic material is molded into an ink container and used as a part, a recycled plastic material is formed through steps of pulverization, cleaning, drying, and foreign matter removal of said part, and physical property values of said recycled plastic material fall within predetermined ranges of physical property values of a virgin plastic material.
A method of manufacturing a recycled plastic material, characterized in that
