中文摘要:
      漆包线铜米漆膜的脱除是困扰再生铜行业的一个难以解决的问题。利用离心式摩擦装置,以铬铁矿砂作为摩擦介质,使铬铁矿砂与漆包线铜米进行充分摩擦,从而达到铜米脱膜精制的目的。根据铜米脱膜工艺,考察了铬铁矿砂粒径、离心式摩擦装置转子转速、铬铁矿砂与铜米混合比、摩擦循环次数等因素对铜米脱膜率的影响。由于漆包线铜米的基体材料是优质的无氧铜,脱除漆膜后可直接再利用。试验结果表明,漆包线铜米脱膜最佳方案为:铬铁矿砂粒径为45目、离心式摩擦装置转子的转速为2700 r/min、铬铁矿砂与漆包线铜米混合比为1.5:1、摩擦循环次数为15次。在此条件下漆包线铜米脱膜率为96.65%,达到直接回收利用的条件。
英文摘要:
      The removal of paint film of copper wire from enameled wire is a difficult problem for the reclaimed copper industry. Using the friction equipment which produced by myself and the chromite ore, and then letting them rubbing absolutely. According to the stripping process of copper meters, we investigate the factors such as chromite ore size, the rotation rate of friction equipment, the mixing ratio of chromite ore and copper meters and friction cycle times to influence the film removal effect. As the copper meters of enameled wire is the best oxygen free copper, so the copper meters which deal with can be reused directly. The experimental results show that the best plan is that: chromite ore size is 45 size, the rotation rate of friction equipment is 2700r/min, the mixing ratio of chromite ore and copper meters is 1.5:1, and copper meters and friction cycle times is 15 times. Under this condition, the film removal rate is 89.65%, and achieved direct recycling conditions.
