         plastics separation methods

         hot separation 离

         wet separation 离

         electrical separation 离

        1, hot separation method

         utilizing add hot rear plastics property achieve separation methods

         hot method

         separation plant/unit electrical add hot material and inner belt/tape 刮刀 空心筒(转鼓)组 formed, and add hot versus 接, 二者逆 toward 旋转, 筒底部连接一 material 槽. material from material add 入, its in plastics formed separation and hot 筒一旦接触开始熔 melt, in upper, use 刮刀刮 lower, material in. method can will 90% above plastics and separation 开, already separation plastics amount very small, can control in 1% below/following.

         hot gas method

         utilizing plastics film hot shrinkage, decrease small ratio principle achieve property film and separation 离. will film and mixed combined material add hot 区, add hot can is 一台农 use material drying machine, pellets 状, from make its surface decrease small, again will it and mixed combined material 送入空 gas separation device, gas will mixed combined material in belt/tape 走, thermoplastic property plastics pellets in separation device 底部. method can plastics and full separation 开.

        2, wet separation method

         will from dry separation method separation equipment to light material 送入搅碎 machine, by 搅碎 纸浆 from separation sheet/plate upper small in 流出, lower plastics from separation export 排出, rear 送入脱 water machine water, again 送入空 gas separation device in separation 离.

        3, electrical separation method

         will and plastics mixed combined material 由一台振动喂 material device separation machine in, 落入旋转 碾碎鼓, rear to electrical electrical and between formed electrical 晕区, by toward electrical 极, plastics still in upper, 随 鼓 转动塑 property to it 底部收集起. using/adopting method wet degree for separation 离结果 has very large effect/influence, mixed combined material wet degree is 15%时, can make and plastics separation 离, property still by a large amount of 纸污染, wet degree improve/increase 至50% above 时, can make property and full separation 离.
