Method and System for Forming a Composite Material
20240317949 · 2024-09-26 ·

A method of forming a composite material includes mixing granules of thermoplastic(s) and granules of reinforcing material(s) using a mixer with an interior friction coating. The friction generated by interaction between the granules and friction coating causes granules of at least one of the thermoplastic(s) to be heated to a liquid or semi-liquid state. The liquid/semi-liquid thermoplastic(s) act a binder for the mixed material. A system for forming such a composite material includes such a mixer with an interior friction coating. The system may also include a mould and/or a press for forming material produced by the mixer into a finished shape. The method and system may use post-consumer and post-industrial material as an input allowing such material to be recycled. In some cases, cross-contaminated or mixed post-consumer/post-industrial material may be recycled, potentially reducing environmental impacts.

20180208844 · 2018-07-26 ·

A method of preparing a solution capable of etching a platable plastic. The method comprises the steps of: (a) providing an electrolyte comprising a solution of manganese(II) in a solution of 9 to 15 molar sulfuric acid or phosphoric acid to an electrolytic cell; (b) applying a current to the electrolytic cell, wherein the electrolytic cell comprises an anode and a cathode; and (c) oxidizing the electrolyte to form manganese(III) ions, wherein the manganese(III) ions form a metastable sulfate complex. Thereafter, a platable plastic may be immersed in the metastable sulfate complex for a period of time to etch the platable substrate prior to subsequent plating steps.
