廢舊電纜處理方法
Disposal method of waste cable
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 uses manual peeling, which has low efficiency, high cost and poor operating environment;
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；廢舊電線電纜處理辦法
2. Incineration method: incineration method is a traditional method, which burns the plastic skin of waste cables and then recovers copper from them. However, the flue gas pollution is very serious. At the same time, the surface of copper wire is seriously oxidized during the incineration process, which reduces the metal recovery rate. This method has been strictly prohibited by the governments of various countries
3.機械剝皮法：采用線纜剝皮機進行處理，廢舊電線電纜處理辦法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: cable stripping machine is used to treat waste wires and cables. This method still needs manual operation, which is semi mechanized, with high labor intensity and low efficiency, and is only applicable to the treatment of thick diameter cables;
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，廢舊電線電纜處理辦法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 wires and cables was put forward in the 1990s. Some countries have studied the treatment methods of waste wires and cables, and China has also carried out research during the Eighth Five Year Plan period. The biggest disadvantage of this method is that the waste liquid can not be treated, which has a great impact on the environment, so it is rarely used;
5.冷凍法：廢舊電線電纜處理辦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，廢舊電線電纜處理辦法但此法的缺點是成本高，難以進行工業化的生產。
5. Freezing method: the disposal method of waste wires and cables, which was also put forward in the 1990s Liquid nitrogen is used as refrigerant to make waste wires and cables brittle at very low temperature. After crushing and shaking, the plastic sheath is separated from the copper section. During the Eighth Five Year Plan period, China has also set up a project to study the treatment method of waste wires and cables. However, this method has the disadvantage of high cost and is difficult to carry out industrial production.
