TREATMENT METHOD OF FRP WASTE FOR SIMPLE MECHANICAL MANIPULATION DURING THE RECYCLING PROCESS OF FRP WASTE

摘要

PURPOSE: A pretreatment of waste FRP is provided to enable easy mechanical manipulation for separation of two layers. CONSTITUTION: A pretreatment of waste FRP containing mat layer(1) and roving layer(2) for enabling mechanical manipulation comprises: a step of coating pretreated solution selected from sulfuric acid and hydrofluoric acid on the waste FRP; and a step of coating soluble dye to the waste FRP 5 minutes after first coating.
