        1. metal device

         will powder waste material pipeline 输送, in process in use metal device will is 0.75---1.2MM metal separation 离出.

        2.静 electrical separation device

         will mixed material powder 碎,投入静 electrical separation device, utilizing metal and plastics different belt/tape electrical features, can separation copper, aluminum and other metal.此 method suitable and metal filling composite/compounding material, cable material and metal plastics 处理.

        3. solvent understanding separation 离

         will coating has plastics coating metal made parts 浸入含二 chlorine 甲烷, non type surface active property agent,石 wax and water liquid in, make plastics coating solvent understanding separation 离.

        4.脆化 separation 离

         make metal and plastics mixed waste material cooling plastics temperature degree,然 rear powder 碎, again use separation method make metal and property separation 离.

        5. cable outer 皮 剥离

         electrical 线, cable outer material main/primary has polyvinyl chloride (PVC), polyethylene (PE) (包括 crosslinked polyethylene (PE)) and combined formed and 天然橡胶, remove upper electrical separation method outer, also has dry method and temperature method types methods can make plastics,橡胶 and copper, aluminum has separation 离.

        (1) dry method separation 离: use outer plant/unit make cable internal uniform add hot, again use 人工剥离 outer 皮.

        (2) wet method separation 离: will aluminum 线浸渍 in agent (surface active property agent) solvent liquid in, add hot 至70—90 degree rear outer 皮,然 rear, again use has machine solvent agent 连续清洗数次,彻底 remove 焦油即 can.
