Build recycling economy of electric wire and cable industry

Information Source:Henan Huadong Cable Co., Ltd  Release date:2014-07-21

China wire and power cable, but not the wire and power cable, China's wire and cable industry compared with foreign advanced enterprises, there is great disparity in the level of management, and technology level, technical content, product quality etc.. I want to explain is two points, first is the low utilization rate of equipment, China's wire and cable equipment utilization rate is about 30% in average utilization rate of equipment, advanced countries in general 70% is normal. An important reason for low utilization rate of equipment is the excess production capacity, excess capacity problem I can be considered, so don't talk.

I want to say is another problem, environmental problem that is the wire and cable industry has been neglected. In fact, pollution during production of wire and cable routine is quite serious; the manufacture, use and waste disposal will produce large amounts of toxic substances such as dioxins, lead, halogen. In recent years, Europe, Japan and other countries American attaches great importance to the pollution associated with the wire and cable, strictly limit emissions, not only the manufacturing process of cables, the government, and the implementation of comprehensive monitoring of processing scrap wire and cable, wire and cable manufacturers to use force to meet the requirements of environmental protection material to replace traditional materials, manufacturing and environmental protection "clean type of wire and cable or wire and cable products", "green wire and cable products".

The developed countries in Europe and Japan, American, wires and cables of various types, various applications, such as high voltage power cables, control cables, communication cables, marine cables, vehicle cable, coaxial cable, telephone cable, instrument by cable, cable, optical cable construction branch, and the environmental protection type of wire and cable supporting bag belt, connector, terminal has extensive use of environmentally friendly products, non environmental protection type of wire and cable has There is not much left. in these areas in the market.

To the production of environmental protection type of wire and cable products, must start from the source, and from first to last in the production process to avoid the harmful material. The green wire and cable products are the carrier of circular economy, green products, the key is from the beginning of the design. Green design and ecological design is based on the environment as the core, using life cycle assessment technology products will be local design method of many contemporary design method of unified as a whole, to achieve optimal overall. Wire and cable industry in China, the ecological design is just beginning, the relevant government departments and local agencies have made relevant provisions.

At present, Beijing city and Shanghai city has banned the use of PVC non environmental protection wires and cables, railway, communication and other departments have been promulgated relevant regulations, in the next few years, the electricity sector in China building, traffic, transportation, communications department and all large and medium-sized city, will also implement a total ban on the use of non environmentally friendly wire and cable.

Environmental protection type electric wire & cable development model is the key material. In wire and cable production, because of its raw material cost accounts for more than 80% of the cost of production, and the copper, aluminum, steel core, rubber, plastic and sheath material as the main raw material costs, which requires the wire and cable enterprises in the aspects of how to design the distinctive products, save raw materials, development of new environmentally friendly materials such efforts. Therefore, consider the following measures must be in the future, to build recycling economy of electric wire and cable industry.

Build recycling economy of electric wire and cable industry should first eliminate cold rolling mill and the black copper rod. Second, actively promote the rare earth aluminum processing technology.

With the continuous casting and rolling process for producing electrical aluminum rod at home has been quite popular, performance is good, but the equipment is still in the early 70's development level, there is not much technical innovation. We must actively promote the optimization of processing technology of aluminum rare endemic to china. And the introduction of some of the key equipment and technology of adding aluminum zirconium alloy, the aluminum melting stove into molten aluminum fuel oil or natural gas furnace, the total elimination of molten aluminum coal burning coal dust and gas emission, and set the flue gas filtration and purification device of flue gas emissions, improve quality, increase yield, reduce the cost, at the same time the conductor temperature increased from 70 ℃ to 150 ℃, carrying capacity is increased by 1.6 times.

Actively introduce advanced technology, independent innovation and development performance of wire and cable equipment is an important means to build circular economy's wire and cable industry. At present, the wire and cable products led the key production equipment and advanced equipment, is still great technology gap, mainly in low productivity, low degree of automation, high energy consumption, poor reliability, still can not meet the needs of the development of the industry, the digestion and absorption of serious lag. Special equipment for wire and cable technology, performance and reliability for good quality, production efficiency, the material utilization rate has immeasurable wire and cable products. To actively introduce advanced technology, wire and cable equipment independent innovation and development of excellent performance, high level, to build electric wire and cable industry cycle of economic service.

Finally, the positive development of environment-friendly electric wire and cable products, strengthen the recycling of scrap wire and cable products.

At present, the production of wire and cable products are widely used in rubber, polyvinyl chloride, polyethylene polymer chemical material. Produce large amounts of toxic and harmful gas in the production process of wire and cable products. Therefore, to actively develop environment-friendly electric wire and cable materials, production of environmental protection type of wire and cable. Japan Fujikura cable companies in the development of the environmental protection type of wire and cable products, in order to monopolize the market, actively promote the government issued the environmental protection type of wire and cable products standards. In recent years, environmental protection type of wire and cable products sales share is expanding rapidly, ordinary wire and cable and cable fire simply cannot compete. Generated in the production process of wire and cable in the leftover materials, can be directly recycled reuse. Recommended the establishment of professional "PVC" waste recycling plant, fixed-point processing, used for other purposes, to avoid pollution two.

In a certain sense, the enterprise competition, technological competition, is to improve the efficiency of resource and resource competition. The essence of the circular economy is through the use of advanced clean production technology to improve the utilization rate of resources, therefore, the enterprise must make important electrical adjustment to the resource utilization and management mode, enterprises should establish a sense of environmental cost in the economic cycle, to focus resources to implement reduction; product reuse; waste recycle principle.
