廢舊電纜利用方法 Waste cable use method 1.手工剝皮法：該法采用人工進行剝皮，效率低、成本高，而且工人的操作環境較差； 1. Manual peeling method: this method adopts artificial peeling, low efficiency, high cost, and poor operating environment of workers; 2.焚燒法：焚燒法是一種傳統的方法，使廢線纜的塑料皮燃燒，然后回收其中的銅，但產生的煙氣污染極為嚴重，同時 ，在焚燒過程中銅線的表面嚴重氧化，降低了金屬回收率，該法已經被各國政府嚴格禁止； 2. The burning method: incineration method is a traditional method, the waste of the cable plastic skin burn, and recovery of copper, but the smoke pollution is very serious, at the same time, the surface of the copper wire in the process of burning of severe oxidation, reduces the metal recovery, the law has been governments strictly prohibited; 3.機械剝皮法：采用線纜剝皮機進行處理，該法仍需要人工操作，屬半 機械化，勞動強度大，效率低，而且只適用處理粗徑線纜； 3. Mechanical peeling method: the use of wire flaking machine is used for processing, which still requires manual operation, which is semi-mechanized, with large labor intensity and low efficiency, and only applicable to coarse diameter cable. 4.化學法：化學法處理廢線纜技術是在上個世紀90年代提出的，一些國家曾進行研究，我國在“八五”期間也進行過研究。該法有一個最大的缺點是產生的廢液無法處理，對環境有較大的影響，故很少采用； 4. Chemical method: the technology of chemical treatment of waste cable is proposed in the 1990s. Some countries have studied it, and our country has studied it during the "eighty-five" period. One of the biggest disadvantages of this method is that the waste liquid produced cannot be processed and has a great influence on the environment, so it is seldom used. 5.冷凍法：該法也是上個世紀九十年代提出的，采用 液氮做制冷劑，使廢線纜在極低的溫度下變脆，然后經過破碎和震動，使塑料皮與銅線段分離，我國在“八五”期間也曾經立項研究，但此法的缺點是成本高，難以進行工業化的生產。 5. Frozen method: this method is also put forward in the ninety s, using liquid nitrogen for refrigerants, waste cable brittle at low temperatures, and then after crushing and vibration, make plastic skin from copper wire section, during the period of "five-year" also once project research in China, but the disadvantage is high cost, this method to industrialized production.
