电线电缆回收推进相关产业转型升级和节能减排
推进我国铜铝产业提质增效,实现转型升级。要解决我国铜铝冶炼和加工产业目前存在的不同程度的产能过剩、技术水平落后和环境污染等问题。
控制行业总量规模,严格审查新上低附加值铜铝项目,提高铜铝冶炼行业准入门槛,促进铜铝工业有序平稳发展。
减少政府对市场的直接干预,加强市场在铜铝资源配置中的作用,通过提高技术标准、环境污染物排放标准、能耗、地耗、矿耗等标准,让市场自行消化过剩产能、淘汰落后企业。促进上下游及周边产业的产业链整合,延伸产业链长度,扩大产业规模,优化产业结构。
出台相关支持政策,鼓励各类企业特别是中小型企业加大科技投入和研发力度,发展特型、特种材料,优化供给侧结构性调整。鼓励企业海外投资,提高国际话语权和竞争力。推动科研攻关,提高科技含量,鼓励企业转型升级,组建技术创新战略联盟,提高对高附值新产品的政策、资金及人力支持,研发优化产品结构,提高竞争力。
严格环境准入标准,推进铜铝产业绿色生产技术与装备升级,倡导全产业节能减排。通过转型升级、提质增效,突破产能过剩、技术水平和资源环境三大压力。?
再者,发挥市场在电力电缆行业铜铝资源配置中的决定性作用,加强政府监督力度。要发挥市场在铜铝资源配置中的决定性作用,兼顾技术可行、安全保障、经济合理、施工维护和节能环保等多个方面,让企业和用户依据铜铝产品的技术和经济特点做出适合自身情况的选择,减少政府直接干预产业政策对市场秩序造成的干扰。
加大政府对电力电缆行业市场监督力度。要严格技术标准,公开产品信息,规范市场秩序,保护科学良性竞争,防止同质化恶性竞争,反对虚假宣传与欺诈行为,通过明确电力电缆产业中铜铝材料选用的技术标准,淘汰落后产能,减少低品质产品恶性竞争对市场秩序的扰乱。
优化市场激励惩罚机制,改变单一罚款的质量监督惩罚方式,严肃处理可能带来安全隐患的产品,改变单一低价的中标方式,为高质量产品提供足够的激励。严防在技术标准过程中出现的寻租腐败行为,杜绝个别企业左右技术标准制定的情况发生,保持技术标准的公正性和合理性。杜绝错误的宣传引导,谨防错误口号误导舆论、损及企业利益和国家发展。??
鼓励和支持电力电缆新技术的研发与推广,提高电力电缆性能,大力推动高等院校与设计单位、企业之间联合开展铜铝材料新技术的研发与推广。推进铜铝电力电缆回收再利用技术的研究,促进循环经济发展,鼓励和推广资源节约、环境友好的技术,拓宽铜铝导体在电力电缆行业中的应用领域。

第一种方法 ;如果要在电缆沟中铺设,在这个情况下,电缆沟的安装要每隔一段时间进行干燥或潮湿程度的检查,这样也是为了保证电缆的完好和质量问题!第二种方法. 也可以放在管道里,这个时间如果是塑料管道,主要管道的损坏,如果是金属的管道,一定要注意管道的导热,这样可能会对电缆电线造成伤害!第三种方法:也可以在.屋檐下,主要一定不要直接暴露在阳光下!第四种方法. 也可以在外墙上。
和上面方法一样,不要直接暴露在强光下!第五种方法.也可以悬空应用/架空电缆。要选择牢靠的方式,还有就是不要光太强!第七种方法 :当然也可以放在地下管道。
The first method; if it is to be laid in the cable trench, in this case, the installation of the cable trench should be dry or humid every other time, so as to ensure the integrity and quality of the cable. Second methods. Can also be placed in the pipe, this time if the plastic pipe, the main pipe damage, if it is a metal pipe, must pay attention to the pipeline heat conduction, which may cause damage to the cable wires! Third way: also under the eaves, the main must not be exposed directly to the sun! The fourth method. It can also be on the outer wall。
As with the above method, do not expose directly to strong light. The fifth method. It can also suspend the application / overhead cable. To choose a reliable way, and not to be too strong! Seventh way: of course, it can also be placed in underground pipelines。

线缆的回收就是采用一定的技术手段,使导体和外皮脱离,然后采用分选技术把导体和外皮分选开,得到较纯净的金属与塑料等,从而达到资源化的目的。 The recycling of cable is to use certain technical means to disengage the conductor and the outer skin, and then use the separation technology to separate the conductor and the outer skin, and get a more pure metal and plastic and so on, so as to achieve the purpose of resource. 常用方法有:焚烧法 The common methods are: incineration method 焚烧法一般是利用电线电缆中塑料的可燃性,采用焚烧的方法来回收电线电缆中的金属。这是一种早期原始的金属回收方法,现已被国家明令禁止,是一种被淘汰的金属回收方法。 Incineration usually takes advantage of the combustibility of plastics in wires and cables, and uses incineration to recover metals from wires and cables. This is an early primitive metal recovery method, which has been banned by the state and is a metal recovery method that has been eliminated. 剥线法 Stripping method 该种方法对于大直径的线缆的拆解在工厂中应用较广泛。自动剥线机工作原理如下图所示,右滚轮步进电机带动上、下右滚轮将夹持的被加工线左右移动;裁刀步进电机带动上、下两裁刀向相反方向运动,通过控制上、下裁刀之间的位移,实现剥皮和裁线的功能; This method is widely used in factories for the disassembly of large diameter cables. The working principle of the automatic stripping machine is shown in the following diagram. The right wheel stepping motor drives the upper and lower right rollers to move the clipped machined line, and the cutter stepping motor drives the upper and lower two cutting tools to move in the opposite direction, and realizes the function of peeling and cutting by controlling the displacements between the upper and the lower cutting tools。
左滚轮步进电机带动上、下左滚轮将夹持的被加工线左右移动;扭线轮步进电机带动上、下左滚轮向相反方向前后运动,实现扭线功能。其中扭线轮与左滚轮在物理上是指同一滚轮。 The left roller stepping motor drives the upper and lower left rollers to move the clipped machined line, and the twisting wheel step motor drives the upper and lower left rollers to move to the opposite direction, and realizes the twisting function. The torsion wheel and the left roller refer to the same roller in physics. 该种方法针对大直径的线缆的拆解有较好的效果。但由于其人工依靠性强,针对中小直径线缆的生产效率太低,自动化程度差,对线缆的类型的分选性差。 The method is effective for the disassembly of large diameter cables. However, because of its strong manual dependence, the production efficiency of small and medium diameter cables is too low, and the degree of automation is poor. 低温破碎法 Cryogenic crushing 韧性物料在破碎加工时会呈现各种塑性、粘性和弹性行为。一般认为颗粒的破碎主要受以下三个因素的影响:温度、冲击速度、粒度,这三个变量控制着破碎的发生和破碎程度。低温破碎的基本原理就是利用制冷技术使物质发生改性脆化而容易被破碎。 Ductile materials exhibit various plastic, viscous and elastic behavior during crushing. It is generally believed that the crushing of particles is mainly affected by the following three factors: temperature, impact velocity and particle size, and these three variables control the occurrence and degree of breakage. The basic principle of low temperature crushing is to use refrigeration technology to make materials brittle and easy to be broken. 低温破碎技术最早实现工业化是在1948年,目前常用的制冷方法有2种:一是制冷剂制冷,二是空气膨胀制冷。 The cryogenic crushing technology was first industrialized in the 1948. There are 2 commonly used refrigeration methods: refrigerant cooling, and air expansion refrigeration two。
目前,低温破碎技术在废旧电路板、废旧线缆的破碎中得到了较好的应用,在液氮冷却下,废旧电路板、废旧线缆变脆,很容易粉碎,但是低温破碎液氮冷却装置成本较高。 At present, the crusher technology has been well applied in the breakage of waste circuit board and waste cable. Under the cooling of liquid nitrogen, the waste circuit board and the waste cable are brittle and easy to crush, but the cost of the cryogenic liquid nitrogen cooling device is high. 机械破碎分选法 Mechanical crushing and sorting method 机械破碎法主要包括破碎和分选两个单元。废旧线缆经破碎单元被分解成一定尺度的颗粒单元,然后经分选单元把铜和塑料分选开从而得到纯净的铜和塑料。 Mechanical crushing includes two parts: crushing and sorting. The waste cable is broken into a certain size unit through the crushing unit, and then the copper and plastic are separated by sorting unit to get pure copper and plastic。
